Laser cooling has been used on a solid film of semiconductor for the first time, reducing its temperature to a chilly 4 K. The work has been done by researchers in Denmark, who suggest that with future developments the semiconductor's temperature could be chilled further so that its vibrations are reduced almost to the quantum ground state in at least one direction.

Policymakers and energy industry experts often talk about clean energy as though it isn’t reliable. In fact, while an MIT study recently found the existing grid would probably be up to the challenge of absorbing clean energy, intermittency does present a real challenge that renewables must address to get to high levels of penetration.

A solar-powered car on a quest to circumnavigate the globe is kicking off a 49-day trek across the U.S. on Tuesday in Half Moon Bay, Calif. Propelled only by the sun’s rays, the two-seat SolarWorld Gran Turismo sports car is slated to travel 21,000 miles and set a “Guinness World Records” record for the longest distance covered by a solar car, according to its co-creator SolarWorld.
