Today’s Google Doodle celebrates the life and career of inventor Robert Noyce, co-founder of Fairchild Semiconductor and Intel. Noyce, who died in 1990, is credited with the invention of the integrated circuit. His patent for a “Semiconductor Device and Lead Structure” paved the way for the semiconductor revolution of the next decades.
He was called the Mayor of Silicon Valley and his relaxed corporate structures encouraged his employees to experiment in an era of buttoned-down austerity. Without Noyce and his various projects, you probably wouldn’t be reading this right now.
Even in the dark early days of the IC, Noyce understood the value and importance of a high-tech education. Quoth Wikipedia:
In his last interview, Noyce was asked what he would do if he were “emperor” of the United States. He said that he would, among other things, “make sure we are preparing our next generation to flourish in a high-tech age. And that means education of the lowest and the poorest, as well as at the graduate school level.”

MAN-PORTABLE NON-LETHAL PRESSURE SHIELD PATENT APPLICATION
- 6 pages
- September 29, 2011
A man-portable non-lethal pressure shield provides both a physical as well as pressure shield. The pressure shield addresses the concerns of military, police and human rights organizations and international law as regards effectiveness, efficiency and safety and efficiency. A folded acoustic horn is incorporated into the physical shell of the shield. The horn couples acoustic pulses from a sonic pulse generator to an acoustic aperture to output a pulsed pressure beam that approximates a plane wave to produce a pressure barrier. The operator may specify a desired effect on its human target that is maintained as range-to-target changes or a desired effect at a specified perimeter range. The shields may be networked to facilitate coordinated action among multiple pressure shields as a force multiplier or to provide a more sophisticated pressure
barrier.…

Long Endurance Multi-Intelligence Vehicle (LEMV), United States of America
The Long Endurance Multi-intelligence Vehicle (LEMV) is a long-range hybrid airship system, developed by Northrop Grumman, for the US Army. The hybrid air vehicle is capable of providing intelligence, surveillance and reconnaissance support for land forces.
In June 2010, the US Army Space and Missile Defence Command / Army Forces Strategic Command (USASMDC / ARSTRAT) signed a $517m contract with Northrop Grumman for three LEMV systems.
Under the agreement, the manufacturer is responsible for completing the design, development and testing within 18 months and should transport the vehicle to Afghanistan for assessment.
Long Endurance Multi-intelligence Vehicle development
"The LEMV's design is based on the HAV304, a hybrid vehicle designed by HAV. The hull of LEMV will be made of laminated fabric."
Northrop Grumman has teamed-up with Hybrid Air Vehicles (HAV), Warwick Mills, ILC Dover, AAI Corporation and SAIC for the LEMV development.
HAV provides the base platform, while Northrop Grumman is responsible for system integration, flight and ground control systems.
The System Readiness Review (SRR), Initial Baseline Review (IBR) and Preliminary Design Review (PDR) of the vehicle were completed by November 2010. The Critical Design Review (CDR) was concluded in February 2011.
Upon completion of the ground and flight testing phase, the vehicle will be transported to Afghanistan in 2012 to take part in an army joint military utility assessment.
Design and features of Northrop Grumman's LEMV
The LEMV's design is based on the HAV304, a hybrid vehicle designed by HAV. The hull of LEMV will be made of laminated fabric.
"The hybrid air vehicle is capable of providing intelligence, surveillance and reconnaissance support for land forces."
It will incorporate internal catenary system for holding a payload module. The aerodynamic shape of the hull delivers up to 40% of lifting for the vehicle.
The internal diaphragms are designed to allow minimal compartmentalisation to enhance fail-safe characteristics of the vehicle. The pressure control is accomplished by multiple ballonets at forward and aft, on either side of the hull.
The payload module placed in the centreline of the hull consists of three sections including flight deck, mid-body and aft-body. The flight deck includes a pilot station, single pilot control, large foils, a fuel control system and payload compartment. The mid and aft bodies accommodate universal load beam and fuel tanks respectively.
LEMV has a length of 91m, width of 34m and a height of 26m. The envelope volume of the air vehicle is 38,000m³. The vehicle can carry multi-intelligence payloads, such as sensors, ground moving target indicator radar, full motion video, signal intelligence and communications relay systems.
The vehicle allows integration of different types of exchangeable payloads, to support wide variety of missions. It can be integrated with a universal ground control station with 100% interoperability and with the distributed common ground system-army (DCGS-A).
Engines and landing gear of the long-range hybrid airship system
LEMV is powered by four 350hp 4l V8 direct injection diesel engines, two forward of the hull and two aft of the hull. Equipped with supercharged induction system, each engine is assembled in ducts with blown vanes. The configuration allows thrust vectoring for optimum control on the motion of the air vehicle.
LEMV is fitted with a bow thruster for low-speed control and loitering capability. The vehicle can supply up to 16kW of electrical power for payload.
Pneumatic tubes are fitted at the bottom of the two outer hulls for amphibious capability. The take-off / landing operations are supported by ballonet fans using a hull pressure system. The vehicle will require only a short runway to perform take-off and landing.
Performance of the US Army's long endurance multi-intelligence vehicle
LEMV can be optionally manned, remotely piloted or autonomously operated. It can fly at a maximum altitude of 20,000ft.
It is capable of carrying payload weight of 2,750lbs. It consumes about 3,500 gallons of fuel to remain aloft continuously for a period of 21 days.
The maximum range of the air vehicle is 2,400nm with 15,000lbs (heavy lift configuration). The vehicle can fly at a speed of 30kt and a dash speed of 80kt.
The Global Military Aircraft Market 2011-2021

I’ve promised to write about the surveillance drone that I’ve been building over the past couple of months. I have always wanted to have my own drone that could send back a live video feed. This is partly inspired by products like the AeroVironment RQ-11 Raven, which is currently in use by the US military, and which you can view in action here. The Raven is basically just a glorified RC airplane, with a sophisticated landing system that allows it to be recovered by a soldier without great pilot skills (which is one reason they cost around $35,000 each).
To get to the bottom line, my drone has taken its first flights, the results of which you can see in a video of my office at Stanford and in a local park.
When my kids were younger I looked into buying an RC helicopter for this purpose and actually tried to wire a camera on a car, but the consumer technology wasn’t up to snuff back then. Now it is.
Instead of using an RC airplane I went with a helicopter for a couple of reasons. I could test the helicopter in my back yard, while an airplane would require a runway. Helicopters are better for precise, close-in surveillance because they can hover. The big drawback is that they are very hard to fly; indeed, learning to fly an RC helicopter is the single biggest impediment to the use of this kind of drone. (Among other reasons, they’re hard to fly because left and right switch meanings on the joystick when the helicopter is pointing toward you.)
I slowly worked my way up the hierarchy of helicopters, from a Syma S107 to a Blade CX2 to a T-Rex 450 (pictured above) to a DJI Innovations F450 quadcopter (below), which is the platform I used for the videos. It is very difficult to learn to fly a helicopter without a simulator; I’ve logged quite a number of hours on RealFlight 6. While many people use the single main-rotor T-Rexs or their clones as platforms for cameras, they are not very stable; their main purpose is acrobatic flying (they can be flown upside down, among other things, because of the main rotor collective pitch). The practical implication of this is that you have to constantly repair your crashed helicopters, which costs lots of money and takes lots of time.
The DJI F450 quadcopter on the other hand uses an extremely sophisticated Naza controller with a three-axis accelerometer that can sense where the machine is going, and automatically corrects for movement. As a result, they are stable and easy to fly. You still need basic piloting skills, and it is often hard, as with many quadcopters, to see where the nose is pointing, making it hard to maneuver properly when at the limit of visual range. But they hover beautifully and have the lifting capacity to loft a small digital recorder which I used for the videos above. I’m currently using an old Sony flip video camera.
It is extremely easy to build a drone now that can do not just surveillance but can carry rather large payloads. If you want to see how large some of these planes get, check out this video of a model Airbus A380. I don’t have to spell out the implications of this. I want to have my drone before the government makes them illegal. The US has been fighting such low-tech enemies lately that we haven’t thought through the nature of a world in which lots of people have sophisticated drones, not just other countries but private individuals. One somewhat worrying thing is that virtually all of this equipment comes from China or Taiwan.
The next stage in this project is to equip the drone with telemetry. I’ve bought the package that includes a real time video transmitter and receiver, camera, and telemetry system that will send back GPS data on the drone’s location, heading, airspeed, etc. This requires, among other things, a ham radio license. Stay tuned.

Our industrial civilization is at a crossroads. Oil and the other fossil fuel energies that make up the industrial way of life are sunsetting, and the technologies made from and propelled by these energies are antiquated. The entire industrial infrastructure built off of fossil fuels is aging and in disrepair. The result is that unemployment is rising to dangerous levels all over the world. Governments, businesses and consumers are awash in debt and living standards are declining everywhere. A record one billion human beings — nearly one seventh of the human race—face hunger and starvation. Worse, climate change from fossil fuel-based industrial activity looms on the horizon, imperiling our own species’ very ability to survive.
Since the beginning of the Great Recession in the summer of 2008, governments, the business community, and civil society have been embroiled in a fierce debate over how to restart the global economy. While austerity measures and fiscal, labor, and market reforms will all be necessary, they are not sufficient to re-grow the economy. Let me explain by way of an anecdote. Just months after arriving in office, the new Chancellor of Germany, Angela Merkel, asked me to come to Berlin to help her administration address the question of how to create new jobs and grow the German economy in the twenty-first century. I began my remarks by asking the chancellor, “How do you grow the German economy, the EU economy, or, for that matter, the global economy, in the last stages of a great energy era and an industrial revolution built on it?”
“It is becoming clear that the Second Industrial Revolution is dying. What we need now is a bold new economic narrative that can take us into a sustainable post carbon future.”
It is becoming increasingly clear that the Second Industrial Revolution is dying and that industrial induced CO2 emissions are threatening the viability of life on Earth. What we need now is a bold new economic narrative that can take us into a sustainable post-carbon future. Finding that new vision requires an understanding of the technological forces that precipitate the profound transformations in society.
A New Economic Narrative
The great economic revolutions in history occur when new communication technologies converge with new energy systems. New energy revolutions make possible more expansive and integrated trade. Accompanying communication revolutions manage the new complex commercial activities made possible by the new energy flows. In the 19th century, cheap steam powered print technology and the introduction of public schools gave rise to a print-literate work force with the communication skills to manage the increased flow of commercial activity made possible by coal and steam power technology, ushering in the First Industrial Revolution. In the 20th century, centralized electricity communication—the telephone, and later radio and television—became the communication medium to manage a more complex and dispersed oil, auto, and suburban era, and the mass consumer culture of the Second Industrial Revolution.
Today, Internet technology and renewable energies are beginning to merge to create a new infrastructure for a Third Industrial Revolution (TIR) that will change the way power is distributed in the 21st century. In the coming era, hundreds of millions of people will produce their own renewable energy in their homes, offices, and factories and share green electricity with each other in an “Energy Internet” just like we now generate and share information online.
“Internet technology and renewable energies are beginning to merge to create a new infrastructure for a Third Industrial Revolution (TIR) that will change the way power is distributed in the 21st century.”
The establishment of a Third Industrial Revolution infrastructure will create thousands of new businesses and millions of jobs and lay the basis for a sustainable global economy in the 21st century. However, let me add a cautionary note. Like every other communication and energy infrastructure in history, the various pillars of a Third Industrial Revolution must be laid down simultaneously or the foundation will not hold. That’s because each pillar can only function in relationship to the others. The five pillars of the Third Industrial Revolution are (1) shifting to renewable energy; (2) transforming the building stock of every continent into micro–power plants to collect renewable energies on-site; (3) deploying hydrogen and other storage technologies in every building and throughout the infrastructure to store intermittent energies; (4) using Internet technology to transform the power grid of every continent into an energy internet that acts just like the Internet (when millions of buildings are generating a small amount of renewable energy locally, on-site, they can sell surplus green electricity back to the grid and share it with their continental neighbors); and (5) transitioning the transport fleet to electric plug-in and fuel cell vehicles that can buy and sell green electricity on a smart, continental, interactive power grid.
The creation of a renewable energy regime, loaded by buildings, partially stored in the form of hydrogen, distributed via a green electricity Internet, and connected to plug-in, zero-emission transport, opens the door to a Third Industrial Revolution. The entire system is interactive, integrated, and seamless. When these five pillars come together, they make up an indivisible technological platform—an emergent system whose properties and functions are qualitatively different from the sum of its parts. In other words, the synergies between the pillars create a new economic paradigm that can transform the world.
The public/private financing of the Third Industrial Revolution infrastructure build-out across the world will be at the very top of the agenda for the international banking and financial community in the first half of the 21st century.
The Shift To Lateral Power
The Third Industrial Revolution is the last of the great Industrial Revolutions and will lay the foundational infrastructure for an emerging collaborative age. Its completion will signal the end of a two-hundred-year commercial saga characterized by industrious thinking, entrepreneurial markets, and mass labor workforces and the beginning of a new era marked by collaborative behavior, social networks and professional and technical workforces. In the coming half century, the conventional, centralized business operations of the First and Second Industrial Revolutions will increasingly be subsumed by the distributed business practices of the Third Industrial Revolution; and the traditional, hierarchical organization of economic and political power will give way to lateral power organized nodally across society.
Lateral power is a new force in the world. Steve Jobs and the other innovators of his generation took us from expensive centralized main-frame computers, owned and controlled by a handful of global companies, to cheap desktop computers and cell phones, allowing billions of people to connect up with one another in peer-to-peer networks in the social spaces of the internet. The democratization of communications has enabled nearly one third of the human population on earth to share music, knowledge, news and social life on an open playing field, marking one of the great evolutionary advances in the history of our species.
But as impressive as this accomplishment is, it is only half of the story. The new, green energy industries are improving performance and reducing costs at an ever accelerating rate. And just as the generation and distribution of information is becoming nearly free, renewable energies will also. The sun, wind, biomass, geothermal heat and hydropower are available to everyone and, like information, are never used up.
When Internet communications manage green energy, every human being on earth becomes his or her own source of power, both literally and figuratively. Billions of human beings sharing their renewable energy laterally on a continental green electricity internet creates the foundation for the democratization of the global economy and a more just society.
Distributed Capitalism
Energy regimes shape the nature of civilizations—how they are organized, how the fruits of commerce and trade are distributed, how political power is exercised, and how social relations are conducted. To understand how the new Third Industrial Revolution infrastructure is likely to dramatically change the distribution of economic power in the twenty-first century, it is helpful to step back and examine how the fossil fuel–based First and Second Industrial Revolutions reordered power relations over the course of the nineteenth and twentieth centuries.
“The distributed nature of renewable energies necessitates collaborative rather than hierarchical command and control mechanisms. This new lateral energy regime establishes the organizational model for the countless economic activities that multiply from it.”
Fossil fuels—coal, oil, and natural gas—are elite energies for the simple reason that they are found only in select places. They require a significant military investment to secure their access and continual geopolitical management to assure their availability. They also require top down command and control systems and massive concentrations of capital to move them from underground to the end users. The ability to centralize production and distribution— the essence of modern capitalism— is critical to the effective performance of the system as a whole. The centralized energy infrastructure, in turn, sets the conditions for the rest of the economy, encouraging similar business models across every sector.
Virtually all of the other critical industries that emerged from the oil culture—modern finance, telecommunications, automotive, power and utilities, and commercial construction—and that feed off of the fossil fuel spigot were similarly predisposed to bigness in order to achieve their own economies of scale. And, like the oil industry, they require huge sums of capital to operate and are organized in a centralized fashion.
Three of the four largest companies in the world today are oil companies—Royal Dutch Shell, Exxon Mobil, and BP. Underneath these giant energy companies are some five hundred global companies representing every sector and industry—with a combined revenue of $22.5 trillion, which is the equivalent of one-third of the world’s $62 trillion GDP—that are inseparably connected to and dependent on fossil fuels for their very survival.
The emerging Third Industrial Revolution, by contrast, is organized around distributed renewable energies that are found everywhere and are, for the most part, free—sun, wind, hydro, geothermal heat, biomass, and ocean waves and tides. These dispersed energies will be collected at millions of local sites and then bundled and shared with others over a continental green electricity internet to achieve optimum energy levels and maintain a high-performing, sustainable economy. The distributed nature of renewable energies necessitates collaborative rather than hierarchical command and control mechanisms.
This new lateral energy regime establishes the organizational model for the countless economic activities that multiply from it. A more distributed and collaborative industrial revolution, in turn, invariably leads to a more distributed sharing of the wealth generated.
The extraordinary capital costs of owning and operating giant centralized telephone, radio, and television communications technology and fossil fuel and nuclear power plants in markets is giving way to the new “distributed capitalism,” in which the low entry costs in lateral networks make it possible for virtually everyone to become a potential entrepreneur and collaborator, creating and sharing information and energy in open commons. Witness twenty something young men creating Google, Facebook, and other global information networks, literally in their college dorm rooms and thousands of small businesses converting their buildings to green micro power plants and connecting with one another in regional electricity networks.
What I am describing is a fundamental change in the way capitalism functions that is now unfolding across the economy and reshaping how companies conduct business. The shrinking of transaction costs in the music business and publishing field with the emergence of file sharing of music, eBooks, and news blogs, is wreaking havoc on these traditional industries. We can expect similar disruptive impacts as the diminishing transaction costs of green energy allow manufacturers, service industries, and retailers to produce and share goods and services in vast economic networks with very little outlay of financial capital.
Democratizing ManufacturingFor example, consider manufacturing. Nothing is more suggestive of the industrial way of life than highly capitalized, giant, centralized factories equipped with heavy machines and attended by blue-collar workforces, churning out mass-produced products on assembly lines. But what if millions of people could manufacture batches or even single manufactured items in their own homes or businesses, cheaper, quicker, and with the same quality control as the most advanced state-of the-art factories on earth?
While the TIR economy allows millions of people to produce their own virtual information and energy, a new digital manufacturing revolution now opens up the possibility of following suit in the production of durable goods. In the new era, everyone can potentially be their own manufacturer as well as their own internet site and power company. The process is called 3-D printing; and although it sounds like science fiction, it is already coming online, and promises to change the entire way we think of industrial production. Think about pushing the print button on your computer and sending a digital file to an inkjet printer, except, with 3-D printing, the machine runs off a three-dimensional product. Using computer aided design, software directs the 3-D printer to build successive layers of the product using powder, molten plastic, or metals to create the material scaffolding. The 3-D printer can produce multiple copies just like a photocopy machine. All sorts of goods, from jewelry to mobile phones, auto and aircraft parts, medical implants, and batteries are being “printed out” in what is being termed “additive manufacturing,” distinguishing it from the “subtractive manufacturing,” which involves cutting down and pairing off materials and then attaching them together.
“In the new era, everyone can potentially be their own manufacturer as well as their own internet site and power company. The process is called 3-D printing.”
3-D entrepreneurs are particularly bullish about additive manufacturing, because the process requires as little as 10 percent of the raw material expended in traditional manufacturing and uses less energy than conventional factory production, thus greatly reducing the cost.
In the same way that the Internet radically reduced entry costs in generating and disseminating information, giving rise to new businesses like Google and Facebook, additive manufacturing has the potential to greatly reduce the cost of producing hard goods, making entry costs sufficiently lower to encourage hundreds of thousands of mini manufacturers—small and medium size enterprises (SMEs)—to challenge and potentially outcompete the giant manufacturing companies that were at the center of the First and Second Industrial Revolution economies.
Already, a spate of new start-up companies are entering the 3-D printing market with names like Within Technologies, Digital Forming, Shape Ways, Rapid Quality Manufacturing, Stratasys, Bespoke Innovations, 3D Systems, MakerBot Industries, Freedom of Creation, LGM, and Contour Crafting and are determined to reinvent the very idea of manufacturing in the Third Industrial era.
The energy saved at every step of the digital manufacturing process, from reduction in materials used, to less energy expended in making the product, when applied across the global economy, adds up to a qualitative increase in energy efficiency beyond anything imaginable in the First and Second Industrial Revolutions. When the energy used to power the production process is renewable and also generated on site, the full impact of a lateral Third Industrial Revolution becomes strikingly apparent. Since approximately 84 percent of the productivity gains in the manufacturing and service industries are attributable to increases in thermodynamic efficiencies— only 14 percent of productivity gains are the result of capital invested per worker— we begin to grasp the significance of the enormous surge in productivity that will accompany the Third Industrial Revolution and what it will mean for society.
Near Zero Cost Marketing and LogisticsThe democratization of manufacturing is being accompanied by the tumbling costs of marketing. Because of the centralized nature of the communication technologies of the first and second industrial revolutions—newspapers, magazines, radio, and television—marketing costs were high and favored giant firms who could afford to devote substantial funds to market their products and services. The internet has transformed marketing from a significant expense to a negligible cost, allowing start ups and small and medium size enterprises to market their goods and services on internet sites that stretch over virtual space, enabling them to compete and even out compete many of the giant business enterprises of the 21st century.
Consider Etsy, a brash, web start-up company that has taken off in the past seven years. Etsy was founded by a young New York University graduate, Rob Kalin, who made furniture in his apartment. Frustrated that he had no way to connect with potential buyers interested in hand-crafted furniture, Kalin teamed up with a few friends and put up a website designed to bring individual craftsmen of all kinds, from around the world, together with prospective buyers. The site has become a global virtual showroom, where millions of buyers and thousands of sellers from more than fifty countries are connecting, breathing new life into craft production—an art that had largely disappeared with the advent of modern industrial capitalism.
Connecting multitudes of sellers and buyers in virtual space is almost free. By replacing all of the middlemen—from wholesalers to retailers— with a distributed virtual network of sellers and buyers and eliminating the transaction costs that are marked up at every stage in the marketing process, Etsy has created a new global craft bazaar that scales laterally rather than hierarchically, and markets goods collaboratively rather than top-down.
“The Internet has transformed marketing from a significant expense to a negligible cost, allowing start ups and small enterprises to compete with many of the giant business enterprises of the 21st century.”
Etsy brings another dimension to the market—the personalization of relationships between seller and buyer. The website hosts chat rooms, coordinates online craft shows, and conducts seminars, allowing sellers and buyers to interact, exchange ideas, customize products, and create social bonds that can last a lifetime. Giant, global companies mass-producing standardized products on assembly lines operated by anonymous workforces can’t compete with the kind of intimate one-to-one relationship between artisan and patron.
Although still in its infancy, Etsy is a quickly growing enterprise. In 2011, Etsy’s sales topped nearly $500 million. In a recent conversation, Kalin told me that his mission is to help foster “empathic consciousness” in the global economic arena and lay the foundation for a more inclusive society. His vision of connecting up “millions of local living economies that will create a sense of community in the economy again” is the essence of the Third Industrial Revolution model. Etsy is only one of hundreds of global Internet companies that are bringing together producers and consumers in virtual marketing spaces and, in the process, democratizing marketing costs across the global economy.
As the new 3-D technology becomes more widespread, on site, just in time customized manufacturing of products will also reduce logistics costs with the possibility of huge energy savings. The cost of transporting products will plummet in the coming decades because an increasing array of goods will be produced locally in thousands of micro-manufacturing plants and transported regionally by trucks powered by green electricity and hydrogen generated on site.
The lateral scaling of the Third Industrial Revolution allows small and medium size enterprises to flourish. Still, global companies will not disappear. Rather, they will increasingly metamorphose from primary producers and distributers to aggregators. In the new economic era, their role will be to coordinate and manage the multiple networks that move commerce and trade across the value chain.
New Business Models and Jobs in the 21st Century
Germany is leading the way into the new economic era. The Federal Government has teamed up with six regions across Germany to test the introduction of an energy internet that will allow tens of thousands of German businesses and millions of home owners to collect renewable energies on site, store them in the form of hydrogen, and share green electricity across Germany in a smart energy internet. Entire communities are transforming their commercial and residential buildings into green micro-power plants. To date, more than 1 million buildings in Germany have been converted into partial green micro power plants. Companies like Siemens, Bosch and Daimler are creating sophisticated new IT software, hardware, appliances and vehicles, that will merge distributed Internet communication with distributed energy, to create smart buildings, infrastructure, and green mobility for the cities of the future.
“The transition to the Third Industrial Revolution will require a wholesale reconfiguration of the entire economic infrastructure of each country, creating millions of jobs and countless new goods and services.”
The transition to the Third Industrial Revolution will require a wholesale reconfiguration of the entire economic infrastructure of each country, creating millions of jobs and countless new goods and services. Nations will need to invest in renewable energy technology on a massive scale; convert millions of buildings into green micro power plants; embed hydrogen and other storage technology throughout the national infrastructure; lay down a green energy internet; and transform the automobile from the internal combustion engine to electric plug-in and fuel cell cars.
The remaking of each nation’s infrastructure and the retooling of industries is going to require a massive retraining of workers on a scale matching the professional and vocational training at the onset of the First and Second Industrial Revolutions. The new high tech workforce of the Third Industrial Revolution will need to be skilled in renewable energy technologies, green construction, IT and embedded computing, nanotechnology, sustainable chemistry, fuel-cell development, digital power grid management, hybrid electric and hydrogen-powered transport and hundreds of other technical fields.
Entrepreneurs and managers will need to be educated to take advantage of cutting edge business models, including distributed and collaborative research and development strategies, open source and networked commerce, performance contracting, shared savings agreements, and sustainable low-carbon logistics and supply chain management. The skill levels and managerial styles of the Third Industrial Revolution workforce will be qualitatively different from those of the workforce of the Second Industrial Revolution.
The lateral scaling of the Third Industrial Revolution shifts the fulcrum of power from centralized global companies to distributed small and medium size enterprise networks. The rapid decline in transaction costs brought on by The Third Industrial Revolution are leading to the democratization of information, energy, manufacturing, marketing, and logistics, and the ushering in of a new era of distributed capitalism that is likely to change the very way we think of commercial life. The Third Industrial Revolution offers the hope that we can arrive at a sustainable post-carbon era by mid-century. We have the science, the technology, and the game plan to make it happen. Now it is a question of whether we will recognize the economic possibilities that lie ahead and muster the will to get there in time.

Report of an Expert Panel on the Future of Army Laboratories
Abstract
The U.S. Army is in the midst of an unprecedented technical transformation as it rapidly adopts and adapts to cutting-edge science and technology to remain an effective and relevant fighting force. This report describes the result of an expert panel assembled to consider how current trends in research and development (R&D) might unfold over time and how those trends could affect the laboratories and R&D centers that support the Army. The panel looked at national trends in basic research and R&D, including trends in Department of Defense research funding; conducted an in-depth examination of the Army research enterprise; and profiled several non-Army laboratories known for their high-quality basic research, to gain insight into how the Army might better structure and fund its own labs. The panel identified several trends, such as an increasing focus on near-term results and tendency toward risk aversion, that are hampering the Army research effort. The report concludes with a list of recommendations for addressing these issues to help the Army get the best long-term value from its investments in basic research.
Arkyd 300 series spacecraft investigates an asteroidSome time in the next 18 to 24 months, Planetary Resources, Inc. will launch a series of mass-produced 9" space telescopes, dubbed Arkyd Series 100 spacecraft. They're specifically designed to identify which of the roughly 8,900 near-Earth asteroids are both smaller than 50 meters and suitable targets for retrieval back to Earth orbit. These small near-Earth asteroids represent a transient population, with life spans in the millions of years, typically cut short by running into a planet or being thrown out of the solar system by Jupiter.
That mission, according to Planetary Resources co-founder Eric Anderson, will be completed well enough within the ensuing year or two that the follow-up spacecraft, the Arkyd Series 200, can track some of these asteroids as they fly by in high Earth orbit. Still later, Arkyd Series 300 swarm spacecraft can begin launching to survey those asteroids from a closer perspective, gathering information on spin, shape, and composition.
In theory, several spacecraft could be launched every year for as long as necessary. At some point, the company would have enough information to launch spacecraft built to travel to an asteroid and retrieve them over several years, ultimately delivering them to a high Earth orbit. By some time in the next decade, both robotic and manned spacecraft would be waiting in orbit for the asteroids as they arrived.
The Obama Administration has set 2025 as the year NASA would be set to attempt a human-asteroid rendezvous, which coincides with the Planetary Resources schedule. Humans would harvest asteroids from that point forward.
The announcement was made on Tuesday morning during a press conference at the Seattle Museum of Flight. Many luminaries from industries well outside space exploration attended the event, as well as scientists and engineers with significant space credentials. Several of those scientists and engineers are either part of the new company, involved in a predecessor company, Arkyd Technologies, or authors of a large enabling report on asteroid mining authored by the Keck Institute for Space Studies. Ars Technica provided some coverage of that report last week.
A model of the Arkyd 100 spacecraft sat on the stage near the podium during the announcement. Chris Lewicki, formerly JPL's flight director for the Mars Exploration Rovers and the Phoenix Mars Lander and now the president and chief engineer of Planetary Resources, detailed the contrast between the one-off approach of government space agencies and the low-cost, mass-production approach of Planetary Resources. But what's the target of that mass production?

The value of asteroidsThroughout decades of academic and industry conferences on engineering and operations in space, thousands of papers on the economics of asteroid mining have been presented by true believers to small rooms full of fellow true believers. The gist of the presentations is that asteroids theoretically contain large percentages of highly pure metals or other materials that would be highly valuable either in space or here on Earth.
One of the foremost materials mentioned enthusiastically in asteroid mining circles is platinum, along with other metals in the platinum group of elements. Palladium, in particular, is used in large quantities in the automotive industry and would be valuable on the Earth. Platinum group metals do not occur naturally in the Earth's crust (they mostly sank to the core with iron), so most or all platinum-group metals used today actually arrived from space in the form of asteroid impacts. So why not go to the source?
What might be a far more valuable resource in the near term is water, necessary for any kind of human presence in space. Because it's comprised of hydrogen and oxygen, it's also the best resource for putting together a propellant depot network throughout the solar system. According to Eric Anderson of Planetary Resources, an 80-meter asteroid the size of the museum gallery in which the press conference took place would certainly have $100 billion-plus worth of materials, whether it was water or platinum. A chondrite asteroid half that size would have enough water in it to power every single space shuttle ever launched.
Essentially, as was detailed in another recent Ars Technica article, propellant depots serve a role much like the one that gas stations quietly serve across the developed world: they make easy travel possible. And because water and oxygen and hydrogen are so difficult to bring up from the surface of the Earth, it's far easier to bring them back from near-Earth asteroids.
But that really isn't why Planetary Resources was formed, at least while there are so few humans in space. Each of the speakers seemed to have a different version of the reasoning.
Peter Diamandis (co-founder): "The mission of Planetary Resources is to gain access to the natural resources of space by mining near-Earth approaching asteroids. With technological advances that are coming out of exponential technologies and investors willing to bear the risk, small teams are able to literally do what only governments and large corporations were able to do before."
Eric Anderson (co-founder): "If it's successful we're going to make a lot of money, but we also understand that we're not going to make it overnight."
Tom Jones (advisor): "We can use most of the materials available on these asteroids to create a thriving economy in space."
Chris Lewicki (President): "Good morning, everyone. I'm Chris Lewicki, and I'm an asteroid miner.
Close on the heels of SpaceX, Planetary Resources will become the second company to enter modern mass production of spacecraft. Many years ago, the Soviets took a mass production approach to their space program, stockpiling rockets and spacecraft for decades to come. With the computerization of machine tooling, modern space companies can produce spacecraft even more cheaply."
Summed up, the short-term goal seems to be to establish the equipment and skills necessary to make a new industry of asteroid mining possible, and the long-term goal seems to be to make the colonization of the solar system by humankind possible. The investors in Planetary Resources would be properly termed "angel investors," since they do not expect to see a return in the short term. (Although, through contract work, the company is apparently operating at a profit at the moment.)
These angel investors form an amazing list. They include Google's CEO Larry Page and Chairman Eric Schmidt, Microsoft billionaire Charles Simonyi, Ross Perot Jr., and James Cameron. Charles Simonyi has been to space twice via one of Eric Anderson's previous ventures, Space Adventures. Ross Perot and James Cameron are also known as adventurers in their own right, and Cameron just returned from a solo submarine voyage to the bottom of the Mariana Trench. All are willing to contribute large sums of money at high risk of loss for what could be a long period of time.
Shouldn't the government put a stop to all this trillionaire tomfoolery?
The Outer Space Treaty, to which over 100 countries (including the US) have became signatories since 1967, states that "the activities of non-governmental entities in outer space, including the Moon and other celestial bodies, shall require authorization and continuing supervision by the appropriate State Party to the Treaty." That requirement remained completely theoretical for the most part over the intervening years. But since the X-Prize competition and the advent of companies like SpaceX, Blue Origin, and Virgin Galactic, the US has been hard pressed to keep up with the sudden burgeoning of the private space industry.
In recent years the FAA's Office of Space Transportation has worked hard to catch up with entrepreneurs. A company proposing to launch a rocket or spacecraft would now apply to that office for a launch permit, subject to continuously evolving standards set by the office. Launch sites must also apply for licenses.
There's no doubt that the Planetary Resources plans will cause a big scramble in the US government, not only at the FAA but within the entities responsible for deciding who owns mining resources in space—provisions don't exist for that kind of activity. A new body of law will need to be fabricated and detailed. The subject matter isn't entirely new; space law is already a growing field and many discussions have taken place over several decades regarding what would happen when this day arrived.
Beyond the legal issues, some people are fearful that an asteroid might be brought back to impact the Earth accidentally, or even used as a weapon. It would be surprising if there aren't several Congressional hearings on the subject called in the years before the first attempt to return an asteroid physically to Earth orbit. Congress is sure not to give up its right to speak about the matter extensively.
What might be surprising, though, is that other than as a recruitment device for space mining companies, NASA really has no involvement in what Planetary Resources is doing, no prior knowledge, and no hardware capable of matching the company's. Planetary Resources plans to essentially mass produce space telescopes, something NASA would never be able to do for political reasons, and one that's hard to justify scientifically. NASA's mission of space exploration will necessarily be informed by the information Planetary Resources (and its followers) will harvest, but NASA has no involvement before now.
Humanity's next big endeavor?
There's an old space industry joke that goes something like, "How do you make a small fortune in aerospace? Start with a large fortune!" And certainly, as practiced up until the present, that's been the rule for many companies. The US government has changed its mind often in the middle of business partnerships, the most recent case being the Congressional struggle with the Obama administration to slow down commercial space.
But in this particular case, perhaps optimism and capitalism will have their day. As was summed up at the press conference this morning, "The best way to predict the future is to make it happen."
How do you test the functionality of a wholly new type of satellite docking system in the weightlessness of space, without shooting round after round of prototype into orbit? If you're DARPA, you float the satellites—air hockey-style—on top of a 37.5-ton slab of granite.
Conventional satellites to this point have generally employed specially-designed, one-off docking systems—and that's only if the satellite is designed to be serviced or maintained in the future. It's not like you can just shoot any service satellite into orbit and expect it to successfully rendezvous and dock with another satellite already in the sky. But that's exactly what DARPA is trying to build. The US agency has funded the Front-end Robotics Enabling Near-term Demonstration (FREND), a project aiming to create a fully autonomous docking capability for satellites that weren't built to be serviced.
FREND will also allow a satellite to reposition its own orbital trajectory. With this ability, fleets of satellites could be moved, say to improve television coverage in times of national crisis. Individual satellites could last longer saving by using this add-on system (rather than their own fuel supplies) to move into safe orbits. This could also destroy dead satellites altogether by plunging them into the atmosphere.
But before the FREND system can be tested in space, it needs to prove its mettle here on Earth. To do that, researchers at the U.S. Naval Research Laboratory Spacecraft Engineering Department, recently built a Gravity Offset Table, the only one of its kind. The table itself is a 20-foot by 15-foot by 1.5-foot single granite slab pulled from Raymond Granite Quarry in Clovis, Ca and honed to a tolerance of +/- 0.0018 inches flat across the entirety of its surface. Prototypes are suspended above the slab using powerful jets known as air bearings. The ultra-smooth, ultra-flat face of the granite accurately reproduces the inertial forces and orbital dynamics found in space, allowing the prototypes a full six degrees of freedom when moving about.
"We accomplish this by floating models of spacecraft and other resident space objects on air bearings—similar to the dynamics of an upside-down air hockey table," Dr. Gregory P. Scott, space robotics scientist, said in a press statement. "Based on the inertia of the 'floating' system, a realistic spacecraft response can be measured when testing thrusters, attitude control algorithms, and responses to contact with other objects."
The Gravity Offset Table testbed is also equipped with a precision optical measurement system to track satellites' positions and orientations, which allows researchers to optimize the approach and docking procedure in the lab.

Using a robot arm, 'Cathy' was able to lift a bottle for the first time in 15 years.

Two people who are unable to move their limbs have been able to guide a robot arm to reach and grasp objects using only their brain activity, a paper in Nature reports today1.
The study participants — known as Cathy and Bob — had had strokes that damaged their brain stems and left them with tetraplegia and unable to speak. Neurosurgeons implanted tiny recording devices containing almost 100 hair-thin electrodes in the motor cortex of their brains, to record the neuronal signals associated with intention to move.
In a trial filmed in April last year and presented with the paper, Cathy, who had her stroke 15 years ago and received the implants in 2005, used her thoughts to steer a robot arm to grasp a bottle of coffee and lift it to her lips. She drank and smiled (see video).
‘We’ll never forget that smile,” says Leigh Hochberg, a neuroengineer at Brown University in Providence, Rhode Island, and a co-author of the paper.
The work is part of the BrainGate2 clinical trial, led by John Donoghue, director of the Brown Institute for Brain Science in Providence. His team has previously reported a trial in which two participants were able to move a cursor on a computer screen with their thoughts2.
“To move from this type of two-dimensional movement to movements involving reaching out for an object, grasping it and then guiding it in three-dimensional space is a huge step for us,” says Donoghue. “It seems like more than one additional dimension in complexity.”
The power of thought
The challenge lies in decoding the neural signals picked up by the participant’s neural interface implant — and then converting those signals to digital commands that the robotic device can follow to execute the exact intended movement. The more complex the movement, the more difficult the decoding task.
The neuroscientists are working closely with computer scientists and robotics experts. The BrainGate2 trial uses two types of robotic arm: the DEKA Arm System, which is being developed for prosthetic limbs in collaboration with US military, and a heavier robot arm being developed by the German Aerospace Centre (DLR) as an external assistive device.
In the latest study, the two participants were given 30 seconds to reach and grasp foam balls. Using the DEKA arm, Bob — who had his stroke in 2006 and was given the neural implant five months before the study —- was able to grasp the targets 62% of the time. Cathy had a 46% success rate with the DEKA arm and a 21% success rate with the DLR arm. She successfully raised the bottled coffee to her lips in four out of six trials.
Scientists are euphoric about the results, which show that people who have been paralysed for many years can still be helped to communicate and perform tasks by themselves. Rodrigo Quian Quiroga, a neuroengineer at the University of Leicester, UK, who was not involved in this study, was “amazed” that the brain’s movement intentions could be read so long after a person had been paralysed. “It’s all very promising,” he says.
But Donoghue stresses that there is long way to go. “Movements right now are too slow and inaccurate — we need to improve decoding algorithms,” he says.
In the meantime, his team is continuing to recruit for the BrainGate2 trial, which is aimed mainly at testing whether the implanting procedure is safe. So far, seven people have received the implants, and none has shown serious adverse effects. The researchers hope to recruit a total of 15 people who have been paralysed by stroke, by neurodegenerative conditions such as amyotrophic lateral sclerosis, or because their spinal cords have been severed.
In the longer term, the scientists want to dispense with the wires that must be attached to a patient’s skull; wireless systems are in development, says Donoghue. Even further in the future, researchers hope to dispense with the robot arms and direct the decoded brain signals straight to the patient’s own muscles.

In a bid to avoid having to send humans into environments with extremely high radiation levels, Toshiba has launched a new robot to help engineers decommission the Fukushima nuclear plant.
Toshiba says the new robot can withstand high levels of radiation, but struggles to climb stairs, is prone to freezing with one leg in the air and once it falls over can’t get up on its own.
The robot, which was specially designed to help decommission Japan's crippled Fukushima Daichi nuclear plant, features a dosimeter to measure radiation and six cameras.
It can also stay in highly irradiated areas, such as a 100 millisievert environment, for about a year. Such environments are extremely dangerous for humans; a rise in cancer becomes statistically detectable at 100 millisieverts, AP reports.
However, the four-legged machine as a few teething troubles. During a jerky demonstration to reporters, it had to be lifted and rebooted by several people, after which it crawled up a flight of eight steps, taking about a minute to get up one step. And if it does fall over, it won’t be able to get up without a helping human hand.
Despite its limitations, Tokyo Electric Power Company (TEPCO), which owns the destroyed nuclear power station, is hoping it might be able to go where they dare not send any human.
The reactors' suppression chamber, which melted down when a tsunami hit the plant in in March 2011, is highly irradiated. TEPCO hopes the robot may be able to help in the cleanup process.
“We need to go in and first check what is there,” said Goro Yanase, Toshiba’s Senior Manager.
The suppression chamber registered a radiation level of 360 millisieverts when it was last measured.
This is not the first time that robots have been used at Fukushima. In April 2011, just a month after the disaster, a Packbot probe was sent into highly irradiated areas – and found temperatures of up to 41 degrees Celsius and humidity ranging from 94% to 99%.
Japanese firms manufacture some of the most advanced robot technologies in the world, but until now their wireless remote-controlled networks have not been designed to cope with high radiation fields.
During the Chernobyl disaster in 1986, robots proved useless and men were thrown into the breach instead. But Toshiba said the robot’s wireless network can be controlled in high radiation by automatically seeking better transmission when reception becomes weak.
If there was any doubt that the military has new confidence in its forthcoming laser arsenal, the Navy’s top geeks want to outfit Marines with a laser cannon to shoot small drones out of the sky.
Specifically, the Office of Naval Research thinks that Marine air-ground task forces are too vulnerable to adversaries flying cheap, small spy drones overhead, like the four-pound Raven the Marines themselves used in Iraq. Its answer: outfit Marine ground vehicles with laser guns.
It’s all part of a new Office of Naval Research program, formally unveiled Thursday, with the clunky name of Ground-Based Air Defense Directed Energy on the Move. For the time being, it’s just a research effort, but the office expects to award grants and contracts for it worth up to $400,000. And it’s doable.
So, the specs. The idea is to get a laser cannon weighing less than 2500 pounds mounted onto a Marine Humvee or comparable truck. The cannon needs to provide a “minimum optical output power” of 25 kilowatts, with an eye toward scaling up to 50 kilowatts, for a two-minute full-power blast. Hardware that can adjust for all “environmental conditions” Marines operate in — from a muggy beach to the arid climes of Helmand Province — is encouraged; the Office is agnostic on how researchers get there.
Is the effort realistic? Yes, but it’s also ambitious.
The Navy is making a big push during 2013 to get its laser arsenal finally out of the lab and into the fleet. The first task anticipated for the laser arsenal is exactly the one envisioned here for Marine trucks — shooting down small drones hovering too close for comfort. The Navy’s had solid-state lasers capable of burning through a boat’s outboard motor at sea for two years, and those models generated 15 kilowatts worth of power. In tests three years ago, an MK-15 Phalanx cannon tricked out to host a laser successfully shot down small drones.
The hard part is going to be generating the power necessary for the laser beam either from a truck or portable within it. The generators on board ships are massive things that can divert enough power to a sub-100 kilowatt laser without jeopardizing propulsion. It’s unclear from the outline the Office of Naval Research provides just how a generator capable of generating 25 kilowatts worth of pew-pew-pew for two minutes and “followed by a 20 minute recharge to 80% of total capacity (power and thermal)” (!) is going to either fit in a Humvee or, more problematically, draw from the truck’s electrical systems. Then there’s the problem of cooling the thing down so it’s safe to drive. (Also, be careful where you point that thing.)
Those are engineering problems that the Office of Naval Research feels confident its industry partners and associated geeks can crack. The effort underscores one of the drawbacks of small surveillance drones, even as they proliferate and generate angst within defense circles: they’re slow and easily shot down — particularly by a line of sight weapon that can burn through them. And the Marines definitely want to demonstrate that as the drones just get cheaper.
