Tag: renewable energyUsing CO2 to Extract Geothermal Energy Carbon dioxide captured from power plants could make geothermal energy more practical. Superconductors to Wire a Smarter Grid A superstation for connecting three independent grids could help solar and wind power. Nanowire anodes could let lithium-ion batteries run twice as long. Coatings and composites ease the air-traffic worries dogging wind power. Ultracapacitor Startup Gets a Big Boost An energy storage startup gets new government funding. A continuously variable transmission could lead to cheaper wind power--if it is rugged enough. Obama Offers Hope for Climate Bill Speaking at MIT, Obama countered recent statements from his administration that climate legislation is bogged down. The low-cost cells make their debut on electronics-charging bags. Cyrus Wadia is using abundant materials to grow nanocrystals for cheaper photovoltaics. Next Stop: Ultracapacitor Buses A U.S.-Chinese venture is out to prove the benefits of quick-charge buses. Natural Gas Changes the Energy Map Vast amounts of the clean-burning fossil fuel have been discovered in shale deposits, setting off a gas rush. But how it will affect our energy use is still uncertain. Michael Idelchik, VP of Advanced Technologies, discusses energy research. GE Grabs Gearless Wind Turbines New direct-drive turbines promise to lower the cost of offshore wind energy. Forecasters see no need for new coal and nuclear power plants. Forget Curbing Suburban Sprawl Building denser cities would do little to reduce CO2 emissions, a new NAS report concludes. |
