The Consumer Electronics Show in Las Vegas this year was awesome and grandiose as always. As I scoped out the latest in tech madness, I was assaulted by a sensory overload of 3-D screen enablers, perceptive sensors, gaming devices for a lazier and racier audience and phones that promise to be smarter than ever before. The general trend in every category seems to be hybrid super gadgets that perform multiple functions like smartbooks which function as smartphones and netbooks that are also e-book readers, smart TVs that display websites, mobile TVs for cars and phones, and so forth.

Shrink Nanotechnologies is one of several companies that is using bioplastics to find a new way of making devices that will minimize the use of increasingly-scarce rare metals.

The company’s OptiSol Solar Concentrator is billed as a nanotechnology-based plastic solar concentrator and solar film. Traditional silicon solar cells absorb only a small fraction of the total incident solar radiation potential, with a majority of the light either reflected or converted to thermal energy.

Carbon dioxide air emissions is one of the big issues in global warming debate. However, before you start controlling by putting the carbon in the ground, you first have to put lawyers in a room to argue. After a year that saw billions of dollars spent around a variety of carbon capture and storage pilot projects, the focus in 2010 will shift from press conferences and engineering discussion to court cases and conference tables.

Everyone has an opinion on what is the right thing to do in global warming. Far from just an engineering decision the task of making technology an effective weapon in the fight against climate change will take a lot more than working out funding details and letting the engineers work.

It’s cleaning up space junk, and is giving us lab-on-chip biofilters for detecting contamination. Now nanotechnology has produced a coating for windows or solar panels that repels grime and dirt. Expanded battery storage capacities for the next electric car could be within reach too.

New Tel Aviv University research, just published in Nature Nanotechnology, details a breakthrough in assembling peptides at the nano-scale level that could make these futuristic visions come true in just a few years.

Operating in the range of 100 nanometers (roughly one-billionth of a meter) and even smaller, graduate student Lihi Adler-Abramovich and a team working under Prof. Ehud Gazit in TAU’s Department of Molecular Microbiology and Biotechnology have found a novel way to control the atoms and molecules of peptides so that they “grow” to resemble small forests of grass.

U.S. researchers have demonstrated a technology that uses the sun’s heat to convert carbon dioxide and water into the building blocks of traditional fuels, a reverse combustion process that may emerge as a practical alternative to sequestration of CO2 emissions from power plants.

The prototype “Sunshine to Petrol” system, developed by Sandia National Laboratories in New Mexico, uses concentrated solar energy to trigger a thermo-chemical reaction in an iron-rich composite located inside a two-sided cylindrical chamber.

The iron oxide is designed to lose an oxygen molecule when exposed to 1,500 degree C heat, and then retrieve an oxygen molecule when it is cooled down, essentially converting an incoming supply of CO2 into an outgoing stream of carbon monoxide.

In spite of leaps and bounds in technology, investment capital, political support and public will over the past decade – much less the past year – there is one element of a revolution that has not emerged in the clean tech movement: an icon. Sure, standard-bearers of the green movement that began in the 1960’s are still visible and active and there are brilliant scientists, entrepreneurs and politicians out there who might be candidates. But, as greens cast about for their own JFK in government, or a Green Gates in the private sector, what they really need is their own Green Gandhi. He may be emerging.

Five years ago the U.S. Environmental Protection Agency assured the nation that the technology credited with opening vast new natural gas supplies was safe. Now Congress has ordered the agency to take another look.

As part of the $32 billion Interior and Environment Appropriations Bill recently signed by President Obama, lawmakers asked the EPA to re-visit hydraulic fracturing, the process where copious amounts of water and sand mixed with toxic chemical additives are furiously pumped underground to break up gas-bearing rock thousands of feet below.

Earlier in the week, Jonathan Axelrad, Co-Chair of this past weekend’s Jewish Response to the Energy Challenge (J-REC) conference held in San Francisco and broadcasted through out the United States and Israel, was asked if a “Jewish response to energy” wasn’t as superfluous as the Korean response to hurricanes.

As one of the few, if not only, gentiles I began the morning a bit skeptical, though after a day of thought provoking lectures and panels, I feel it was not another superfluous conference, and the concept of a concerted Jewish response could indeed be the seed of a terrifically successful piece of the large puzzle that will be the energy (and consumption) solution of the future. The core ideas behind why I agreed with the many bright panelists and moderators for why there should be a particularly Jewish response is because of the interdisciplinary and international nature of the energy challenge, the acute water and related energy challenge within Israel, and the Jewish concept of tikkun olam (loosely translated from Hebrew: the pursuit of things that avoid social chaos).

For more than 40 years, scientists have dreamed of collecting the sun’s energy in space and beaming it back to Earth. Now, a host of technological advances, coupled with interest from the U.S. military, may be bringing that vision close to reality.

Despite the enormous promise of solar power, the drawbacks of the technology remain significant. People need electricity every day, around the clock, but there’s no part of the United States that is cloud-free 365 days a year — and no solar radiation at night. You have to find some way to store the energy for those sunless periods, and there’s not yet a large-scale way to do that.

Moreover, the best locations for solar arrays — the deserts of the American Southwest — are far from the centers of population, so even under the best of circumstances you’d have to send electricity many hundreds of miles through transmission lines that don’t yet exist.

NPR’s On Point never disappoints, and their show with Christopher Steiner, author of $20 Per Gallon: How the Inevitable Rise in the Price of Gasoline Will Change Our Lives for the Better was no exception. Steiner’s thesis is that as liquid hydrocarbons become all the more difficult to naturally extract and regulation makes them all the more costly to refine and use, prices will inevitably rise. At $20 a gallon, we might not recognize our lives…all for the better, says Steiner.

People will live and buy their locally-grown produce in mixed-use developments clustered around high-speed rail lines. In Steiner’s view, $6 a gallon is an inflection point that begins to redefine the way we live our lives. But, will innovation (or the US government) ever allow prices to remain at that level? Not according to Mark Mills, co-author of The Bottomless Well: The Twilight of Fuel, the Virtue of Waste, and Why We Will Never Run Out of Energy.
