Cotton threads: As good as a metal wire to conduct electricity?

A Cornell Univ. team has developed cotton threads that can conduct electric current as well as a metal wire can, yet remain light and comfortable enough to give a whole new meaning to multi-use garments.

New energy source comes from the common pea

New energy source comes from the common pea

If harnessing the unlimited solar power of the sun were easy, we wouldn't still have the greenhouse gas problem that results from the use of fossil fuel. And while solar energy systems work moderately well in hot desert climates, they are still inefficient and contribute only a small percentage of the general energy demand. A new solution may be coming from an unexpected source—a source that may be on your dinner plate tonight.

Silicon nanowires trap sunlight

Silicon nanowires trap sunlight

Solar cells made from silicon are projected to be a prominent factor in future renewable green energy equations, but so far the promise has far exceeded the reality. While there are now silicon photovoltaics that can convert sunlight into electricity at impressive 20% efficiencies, the cost of this solar power is prohibitive for large-scale use. Researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab), however, are developing a new approach that could substantially reduce these costs.

A clean energy America…is it coming or not?

A clean energy America…is it coming or not?

Almost a year ago, the buzz during the downturn was that the economic stimulus will help boost jobs in a sort of national improvement program reminiscent of the 1930s. Our coal would be phased out. Our grids would get smart. Our cars would get hybridized.

Flexible solar cells created with silicon wire arrays

Flexible solar cells created with silicon wire arrays

Using arrays of long, thin silicon wires embedded in a polymer substrate, a team of scientists from the California Institute of Technology (Caltech) has created a new type of flexible solar cell that enhances the absorption of sunlight and efficiently converts its photons into electrons.

Rethinking renewable energy strategies

Researchers at Queen’s Univ. suggest that policy makers examine greenhouse gas (GHG) emissions implications for energy infrastructure as fossil fuel sources must be rapidly replaced by windmills, solar panels and other sources of renewable energy.

Partnership to launch bright, liquid-free future for solar energy

Partnership to launch bright, liquid-free future for solar energy

P2i, a leading maker of liquid repellent nano-coating technology, has teamed up with U.S.-based to commercialize a new plasma process that dramatically reduces the surface energy of a material so that when liquids come into contact with it, they form beads and simply roll off.

NREL expansion targets solar power

NREL expansion targets solar power

The National Renewable Energy Laboratory, Golden, Colo., will spend $5.4 million in federal stimulus funding on facilities to study advanced concepts in concentrating solar power (CSP).

New solar distillation pond methods developed

New solar distillation pond methods developed

Ecosystems of terminus lakes around the world could benefit from a new system being developed at the Univ. of Nevada, Reno to desalinate water using a specialized low-cost solar pond and patented membrane distillation system powered by renewable energy.

Solar irrigation improves diet, income in sub-Saharan Africa

Reliance on rain-fed agriculture has led to tenuous lives for many rural residents of the sub-Sahara, which has prompted the development of a solution to irrigation without centralization power. A two-year study by Stanford Univ. found that solar-power pumps and drip irrigation were effective at battling the shortages of the dry season.

Much ado about next to nothing

Much ado about next to nothing

The recent review of the past 10 years of the National Nanotechnology Initiative--as presented by the President's Council of Advisors on Science and Technology--suggested the rise of nanomanufacturing as the near future of nanotechnology. But the actual proposed funding reflects a cautious approach, even about nanotech in general.

Lunar tires, space MRSA, and resonating microfluidics

Lunar tires, space MRSA, and resonating microfluidics

I typically attend the annual Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy each year in pursuit of specific coverage. This year, I sought out candidates for coverage in a vacuum technology article, and pulled together some instruments for a spectroscopy guide. But as busy as that kept me, it wasn’t all mass spectrometers and vacuum pumps on the show floor.
