Smart grid for electric vehicle fleetWed, 05 Mar 2014 08:46:12 EST
Being able to charge up to 30 electric cars at once requires some ingenious energy management. Researchers are incorporating a mix of renewables into the design of a smart grid for Germany’s largest charging station. Transparent, color solar cells fuse energy, beautyTue, 04 Mar 2014 13:00:29 EST
Colorful, see-through solar cells could one day be used to make stained-glass windows, decorations and even shades that turn the sun's energy into electricity. Solar power: Making it less expensive and more efficientTue, 04 Mar 2014 09:50:33 EST
Researchers are reporting early results on a way to make solar-powered panels in lights, calculators and roofs lighter, less expensive, more flexible (therefore less breakable) and more efficient. Artificial photosynthesis: Key intermediate steps in artificial photosynthesis reaction identifiedTue, 04 Mar 2014 09:50:25 EST
The first direct, temporally resolved observations of intermediate steps in water oxidation using cobalt oxide, an Earth-abundant solid catalyst, revealed kinetic bottlenecks whose elimination would help boost the efficiency of artificial photosynthesis systems. A new renewable energy source? Device captures energy from Earth's infrared emissions to outer spaceMon, 03 Mar 2014 15:40:15 EST
When the sun sets on a remote desert outpost and solar panels shut down, what energy source will provide power through the night? A battery, perhaps, or an old diesel generator? Perhaps something strange and new. Scientists now envision a device that would harvest energy from Earth's infrared emissions into outer space. Heated by the sun, our planet is warm compared to the frigid vacuum beyond. Thanks to recent technological advances, the researchers say, that heat imbalance could soon be transformed into direct-current (DC) power, taking advantage of a vast and untapped energy source.
