UCLA researchers create polymer solar cells with higher efficiency levels
“Previously, the synthesizing process for the polymer was very complicated. We’ve been able to simplify the process and make it much easier to mass produce,” said Jianhui Hou, UCLA postdoctoral researcher and co-author of the study. “Though this is a milestone achievement, we will continue to work on improving the materials. Ideally we’d like to push the performance of the solar cell to higher than 10 percent efficiency. We know the potential is there.”

Heat we emit could warm the Earth
Cowern and Ahn’s argument is logical, says Jonathan Gregory, a climate expert at the University of Reading, UK. “Human energy dissipation is currently small compared with other factors, but you can imagine it becoming much bigger.” However, he adds that energy production would need to grow significantly for the effect to kick in. “It’s fair to ask if we could ever produce so much power,” he says.

Solar Power Concentrator that concentrates sunlight 900 times to produce 1,500 watts of power
Imagine a machine that can concentrate sunlight 900 times and direct a precisely controlled, white-hot beam at a nearby target.
A solar death ray?
No, far from it.

It’s a 1.5 kilowatt power plant. And two poeople can assemble it in half a day without a crane or other special tools. Plus, it generates prodigious amounts of usable heat as well as electricity.
Standing 18 feet high with “wings” spanning 13 feet, the generator is small enough to tuck into some backyards or plant 90 to an acre in a kind of high-tech orchard farm.
