Breakthrough furnace can cut solar costs

(PhysOrg.com) -- Solar cells, the heart of the photovoltaic industry, must be tested for mechanical strength, oxidized, annealed, purified, diffused, etched, and layered.

Microwave ovens a key to energy production from wasted heat

More than 60 percent of the energy produced by cars, machines, and industry around the world is lost as waste heat – an age-old problem - but researchers have found a new way to make "thermoelectric" materials for use ...

Beaming rockets into space

Space launches have evoked the same image for decades: bright orange flames exploding beneath a rocket as it lifts, hovers and takes off into the sky. But an alternative propulsion system proposed by some researchers could ...

Microwaving Water from Moondust (w/ Video)

NASA is figuring out how to make water from moondust. Sounds like magic? "No magic--" says Ed Ethridge of NASA's Marshall Space Flight Center "-- just microwaves. We're showing how microwaves can extract water from moondust ...
