Designing the First Fully Sustainable Block in the U.S.

In the near future, a crumbling parking lot in downtown Dallas, Texas will be the location of the first fully sustainable, urban square block in the United States. Re:Vision Dallas is the sixth competition in a series from the San Francisco, California-based organization, Urban Re:Vision – a group of people focused on changing the urban landscape by re-imagining the components which make up a city block.

World's First Full-Scale Floating Windmill to Undergo Testing

News of the world's first full-scale floating windmill being built spread over a year ago. Now, the Hywind has reached its final destination, where it will face rigorous testing. The Hywind concept combines known technologies in a novel way: a 2.3 MW wind turbine is attached to the top of a Spar-buoy, a solution familiar from production platforms and offshore loading buoys. It captures the wind's energy where the wind is strongest – out at sea.

Yb14MnSb11 as a High- Efficiency Thermoelectric Material

NASA’s Jet Propulsion Laboratory has found Yb14MnSb11 to be well-suited for use as a p-type thermoelectric material. The figure of merit that characterizes the thermal-to-electric power-conversion efficiency is greater for this material than for SiGe, which, until now, has been regarded as the state-of-the art high-temperature p-type thermoelectric material.

Utilizing Ocean Thermal Energy in a Submarine Robot

A proposed system would exploit the ocean thermal gradient for recharging the batteries in a battery-powered unmanned underwater vehicle (UUV) of a type that has been deployed in large numbers to research global warming. A UUV of this type travels between the ocean surface and depths, measuring temperature and salinity.
