Tag: efficiencyA new device could convert conventional electricity meters, making the smart grid cheaper. Cash-Strapped Green Tech Changes Strategy The economy is slowing the progress of green technologies, but energy efficiency and clean coal continue to attract money. A new fuel cell uses a cheap nickel catalyst. A biomimetic ceramic that is strong and tough could be used to make lightweight vehicles. An engine from Lotus and Continental Powertrain consumes 15 percent less fuel. Thin but efficient solar cells use one-tenth the silicon of conventional cells. Nanocrystals could light the way to using LEDs to replace the lightbulb. A new solar laser could be instrumental in the quest to use magnesium as a source of energy. Startup Heliovolt could help bring high-performance thin-film solar cells to market. A Better Way to Make Hydrogen? A Purdue researcher claims aluminum alloys could make fuel-cell vehicles practical. A Better Gauge on Battery Life A new battery-gauge chip could make mobile phones more reliable and help them last longer on a single charge. Silicon Nanocrystals for Superefficient Solar Cells Research shows that silicon can wring two electrons from each photon of incoming light. Smaller, Cheaper Biofuel Reactors A new catalytic process efficiently converts biomass to syngas. A new type of engine could be relatively inexpensive.
