Is kite power economically viable in the 21st century? We'll find out. The TwingKite,  based on Empa's Tensairity technology, is set to take flight thanks to a  “Venture Kick” jury that is…

A National Renewable Energy Lab researcher at the IEEE Photovoltaic Specialists Conference in Tampa announced a 31.1% conversion efficiency for a two-junction solar cell under one sun of…

Natural gas is much cleaner than coal but it's also important that its energy return on investment (EROI) - the total input energy with the energy expected to be made available to end users - is…

With nuclear power trapped in committee meetings and biofuels exposed as a bad idea, the search for another carbon-neutral alternative is ongoing. While the sun gives us enough energy in an hour to…

Fuel cells can be as efficient (or more) than internal combustion engines, silent, and at least one type produces zero greenhouse emissions at the tail pipe. Car and bus manufacturers as well as…

Lignocellulosic waste such as sawdust or straw can be used to produce biofuel – but only if the long cellulose and xylan chains can be successfully broken down into smaller sugar molecules. To do…

Young entrepreneurs tackling hard problems and billion dollar markets took top prizes at the First Look West (FLoW) regional finals competition with technologies that recover waste energy…

The U.S. Department of Energy has approved a Small Business Innovative Research (SBIR) Phase 1 grant proposal for $149,900 to study the differential data from retrofitting a concentrated solar…

Global use of nuclear power has prevented about 1.84 million air pollution-related deaths and release of 64 billion tons of greenhouse gases that would have resulted from burning coal and other…

People generally like the idea of wind energy, they just don't want generation facilities anywhere near their homes. Or, in the case of offshore wind power, their yachts. But remote, cold places may…
