The Advanced Research Projects Agency for Energy (ARPA–E) works on a three-year cycle: Funded projects have three years to prove worthy—or not. Program directors who help fund projects such as Plants Engineered to Replace Petroleum (PETRO) or Batteries for Electrical Energy Storage in Transportation (BEEST) have three years to steer the research. And, after three years at the helm as the founding director of ARPA–E, mechanical engineer Arun Majumdar has announced that he will be stepping down in June.

"Under Arun's leadership, we have seen ARPA–E grow from a fledgling program to become a leading agency for innovation and energy research," Secretary of Energy Steven Chu wrote in an e-mail announcing the surprise change. "Arun has been an invaluable resource to me, to the department, to the administration—and we will miss his leadership."

Majumdar has led the agency's quest for what Secretary Chu has called "a second Industrial Revolution, a revolution that gives [the] developed and developing world the energy it wants and needs, but that can be clean energy," overseeing more than $500 million in funding for roughly 180 projects in 12 program areas. He even helped devise program acronyms like PETRO.

Modeled on the Pentagon's successful Defense Advanced Research Projects Agency (DARPA) but uniquely focused on developing energy technologies that can be cheap and have a big impact, ARPA–E has already seen some of its most successful projects garner an additional $200 million in private investment. "Pound for pound, dollar for dollar, it's hard to find a more effective thing the government has done than ARPA–E," argued FedEx chairman Fred Smith at the agency's most recent conference.

Scientific American spoke with Majumdar about ARPA–E and its future at the agency's third annual conference in March.

[An edited transcript of the conversation follows.]

ARPA–E has recently announced some successes like a new, more energy-dense lithium ion battery. As these technologies flower or fail, how do you reassess your programs?
There are the original milestones in the cooperative agreements that we have with projects. Before we start any project, before we even have a contract signed, we negotiate technological milestones, which in [the case of the Envia battery] included both energy density and cycle life. For the successes like Envia, they will probably have to raise some private sector money, which they are doing. General Motors is investing in the technology, for example. They will need more to put up a manufacturing plant. Ultimately, it's a business proposition. I don't know exactly what they're doing. They don't have to share it with us. I would love to see them off and running.

How does it work with other parts of the Department of Energy (DoE)? Do you sometimes hand projects off?
The DoE has applied-energy programs. Some technologies take longer for the private sector to come in. That's where applied energy programs are helpful in general—to carry on the baton to the point where the private sector comes in.

    Sounds like a real neat idea, working 3 years then giving it up to some new blood. That should keep the interest up on going into and coming out of a program.

    I guess my first question is why do places that seriously address the energy questions get so little attention but mention religion and you get over 100 responses in days. Hamradio thank you for posting, hopefully you will have responses.

    My response to anything dealing with energy are three fold.
    1) Carbon in the forms of graphene, graphite,nanotubes, buckeye balls, carbon composites and the growth and farming of synthetic diamonds. Carbon continues to show conductive, semiconductive and nonconductive properties and in the form of graphene it has been shown to tunnel 100% of the time. Carbon is easy to mold into new products and we have a lot of it. Today we burn it, waste it and are killing ourselves with the stupidity of these practices.
    2) Cynobacteria is able to poop H2 and O2 prolifically and sustainably allowing the creation of a H2 based society. Germany is currently laying down an infrastructure of H2 delivery systems in the to fuel cells and H2 as fuel. Gee wiz, when you oxidize H2 you get water. Last I checked it is not a green house gas.
    3) In 2006 Sciam did an amazing article on a scientist from MIT who was custom tipping viruses to create nano devices at will. She had demonstrated successful creation of batteries (DARPA is currently implementing this) but also of any other electronic device you can imagine. Picture a computer imbedded in your clothes. This was real science and she won scientist of the year that year and now you have to buy the original article.

    So my point is that we have a lot of technology in place that works, has been tested and has then been put back on the shelf so we can continue to kill our selves using fossil fuel. If you are interested in section 2 and 3 of this comment follow these links. As I said the one that actually dealt with the science of custom tipping viruses now is for sale only but you can dig through the chaff and get the dirt on most of it.

    Also of interest
    http://www.scientificamerican.com/article.cfm?id=scientific-american-50-re

    So take a minute and scratch your head, like I have and ask why are we waiting to implement these technologies. One hint I will give you is on the cynobacteria there was a Shell Oil ad posted on the site for several years. Interesting, very interesting but stupid!

    I liked the questions better than the answers. Questions about nuclear energy were bypassed. ARPA-E funds no such research. Questions about hydrogen production ignored the obvious (to nukes) high temperature dissociation of water using a copper-sulfate catalyst process to make hydrodgen with a 50% thermal/chemical conversion efficiency.

    The whole idea of Government innovation is itself an oxymoron. It is right up there with "military justice" or "Central Intelligence". I challenge readers to supply examples of innovation that was funded by or created by our government.

    Why not Arun Majumdar did research on very small unit of wind solar and water energy project.In India some NGO did wonderful project on these energy. Every project is very small only provide to village energy by water, or wind or solar system.Expenses are limited., field are limited.Wasting money on big project I think if Majumdar spend his energy on small unit he can give more result to society

    AT LAST?????

    ODEANOGENIC POWER: http://ireport.cnn.com/docs/DOC-654397

    Hydropower, super clean, cheap, efficient, and now, enough. The same that moves the oceans: the earth's rotation around its own axis, and the force of gravity, mainly between the earth and moon.

    The possibility of loss due to thermodynamic reasons, can we dismiss this, as only the movement of
    the oceans is causing this type of wear and is
    many "illions" of times larger than the energy used by mankind.

    Sounds interesting. Distribution issues but they may not be that hard to overcome. I like it better than putting turbines in the gulf stream which was discussed several years ago.

    I would hope an ecological study is done to make sure we are not killing or decimating feedback systems to tap this but on the surface it has a lot of merit.

    Dear friend, what you say is true, but to reach the levels of generation that US and the world needs, the current control technology allows to ride the wave that it will form in the interoceanic "spillway" entries, varying its height according to the energy needed, and in resonance with the lunar cycle.

    Also, this hydropower, because it involves a field of turbines, is unique in that, for maintenance, you can stop a turbine while another replaces its service, and sustain profitability. This will allow put appropriate filters or ecological barriers for the control of species, again for the first time, while remaining profitable.

    We are smarter than the fish, we only need water to generate energy, and we talk of a sea bed, totally artificial. For land animals, we may well do ecological bridges.

    Sorry and please, this is for experts, who also want to solve the ecological problem of rising prices, that peak oil production is causing, and which is killing already by starvation both men and women, at least in Panama.

    It is a shame we do not tap into tidal pools and use a lock like system that when the tide is in locks and like a ratchet releases the water in a synchronous method allowing us to create hydro electric power.

    During the inflow of tides we can preform the same operation in reverse and once it is in the tidal pool and locked in so to speak we can control the release of the energy even if it is not the same day. I would imagine with all the inlets that exist especially in designated dead zones where there is no ecological impact we could at least create some proof of concept experiments. I know free energy sounds quixotic but it is not free just smart use of energy that is available.

    But then poor poor big oil would not benefit with the commodity based economics that drive non renewable resources. Shame that greed trumps need.

    The apex of ecological pyramid is the man. I'm Catholic: every human being.

    Therefore, I disagree with a violent change of infrastructure, either by war or by disruptive technologies.But in the second case, the history and logic demonstrate the ability of human creativity, working in peace and quiet, to develop the necessary and make a peaceful transition, and as we need today: friendly with the planet, and for the future in harmony with the Universe.

    The latter vanishes fanatical concern for the overpopulation issue directly solved, by some animals, and unconsciously by the Chinese, and even emerge, for fans nervousness: the need for another version in this regard.

    I agree that hydrogen and oxygen are the solution, even friendly with the current infrastructure, as energy carrier.

    But dismissing solutions that can already start production, clean and massive, of hydrogen and oxygen (such as oceanogenic power, and the simple electrolysis of sea water) by others that need more research time, is evidence of harmful manipulation by those who do not really care, find solutions, but unfortunately, have the money that determines who makes the decisions.

    I fear we do too much damage to the ocean already. Keep in mind 90% of the fresh water in the world is underground and we have a plethora of dead zones where we can do no more wrong.

    Some one talked about putting turbines in the gulf stream, that would be like leaving a large truck turned sideways on I-95 and walking away. Almost all migratory sea life uses the streams/rivers in the ocean, I would much rather work with places we have already killed and the cynobacterias are a remnant or collateral damage in these areas.

    The bacteria research was done in 93, resurrected in 2010 and put back to bed. As the article says it works, it is prolific, it eats chlorophyll, and it creates both gasses somewhat as a just in time method.

    Oceanogenic power, uses an artificial spillway. The only place where you can build, is Panama, and is enough for all the world in 200 years and more.

    Putting turbines where there are fish, and not be able to put up barriers to protect them, is a worse solution. Although I know a friend who has designed a wind turbine to protect birds.

    But these turbines have only 50% efficiency. In case, that I suggest, the efficiency goes to 90%.

    But the other major ecological problem, my friend Russell, is that if we do not produce enough clean energy, oceans, atmosphere, and land already are being destroyed, at least, in the surroundings of the gigantic current generation of dirty power.And we must add the ecological damage, by the wars that have already begun, for the last drops of oil.

    Again it seems that arguments without sufficient review by the right people, but very well financed and marketed in the media, are trying to block real solutions.

    I myself am proof of this: I inform you that in Panama, the friends of these procedures have me fired from my job because of my discovery: oceanogenic power.

    Exactly. This is to outsmart the fish. And besides this solution, oceanogenic power, to maintenance or even for fishing, can completely stop a turbine of any size without ceasing to produce a single watt of all power demand.

    Imagine the cost in Hoover dam to clean alleged ecological barriers or filters: At some point would have to stop serving by weeks, up to 130 MW to change these filters. This is inconceivable to this project, but not in the case of oceanogenic power.

    Hydrogen Peroxide is very useful and again not a terrible waste product. I have seen the formula and arrangement. I think the only by product to be wary of is O3 and that is at our low level, it is a benefit in the higher levels of the atmosphere but lung burning and almost caustic at sea level.

    If someone sees an article that is a must see then please send to dcota@aol.com. Make sure you mark it from as relating to the article and I will check it. That goes for any other contributors. I love the give and take and yes we have some clowns but we also have some great minds that can see the elephant from a different vantage point. One of my favorites is a gentleman whose tag is Carlye and he is from Australia. He is more conservative than I and makes me have to think a lot harder but the conversations I have had with him are very enlightening.

    Regarding the waste product H2O2, I have used it on occasion but never to dye my hair.

    I would be interested in finding a solution to creating an output that creates tritium that may be useful in the search for fusion. I still have doubts on fusion but a lot of money and pride is on the line. Freeman Dyson warns of projects such as that in Gaia and Eros but still countries like to spend money on big guns, trucks and other things that make you think something else is lacking.

    My self is a Carbon fan but not of burning it. I love that two Nobel prizes were awarded for graphene research and I think the future is in nanotubes, synthetic diamonds, graphene as a conductor, nonconductor and semiconductor and as a building block for nanotubes which may drive the need for rare metal back to the stone ages and provide much better efficiency in products coming down the road.

    Also Angela Belcher did wonderful work several years ago by custom tipping viruses but only DARPA has picked up on this scientist of the year's work in 2006. And my favorite from 2010 is the little bug that poops O2 and H2 and only needs chlorophyll to start the engine running.

    What I do think is exciting is that at the end of the 19th century scientist were pretty sure everything was found and only the details needed filled in. We started the 21st century realizing we know nothing yet. Carry on Schultzy, carry on.

    Right David, but Truth is also universal, or Catholic. I speak not of the catholic religion, but of Catholic truth.

    As written so far, upper and lower case have meaning.

    If we are honest or we fear the truth, the division of religions is because we all want to manage the collection of money. That is, we want power. And this is because we do not want to be crucified.

    The good news is that current advances in communications, are evidence that we are walking to the unit by the beauty of Truth.
