Miles-High Kites Could Generate Electricity

Airborne turbines like these depicted in this illustration could generate electricity from strong high-altitude winds

The sky might literally be the limit for wind power — rotors spinning miles high could help supply electricity worldwide. "There is a huge amount of energy available in high-altitude winds," said researcher Ken Caldeira at the Carnegie Institution's Department of Global Ecology in Stanford, Calif. "These winds blow … Continue reading

A ceremony for the Jindo Uldolmok Tidal Power Plant was held in Uldolmok, an area off Jindo, an island in South Jeolla Province, according to the … Continue reading

Improving Performance of Nanotubes in Solar Cells that Produce Hydrogen Gas from Water

Scanning electron microscope image of typical titania nanotubes for a photocatalytic cell to produce hydrogen gas from water

A research team from Northeastern University and the National Institute of Standards and Technology (NIST) has discovered, serendipitously, that a residue of a process used to build arrays of titania nanotubes-a residue that wasn't even noticed before this-plays an important role in improving the performance of the … Continue reading

Swift Wind Turbine

swift_01

The Swift Wind Turbine was developed by Renewable Devices in Scotland, and is the first quiet rooftop turbine that generates electricity by harnessing the power of the wind as a cost effective energy source for home, commercial, and industrial applications. The Swift generates an of average of 1,680 watts of immediate … Continue reading
