Solar power cells need to stay relatively cool for the sake of both efficiency and longevity, but active cooling (like ventilation) isn't practical; it's expensive, and may block the very rays the cells are supposed to collect. To tackle this problem, Stanford University researchers have created a...

Thermoelectrics -- which use wasted heat to generate electricity -- could get a lot more interesting thanks to a company called Alphabet Energy. It's set to commercialize tetrahedrite, a metal that more than doubles the efficiency of current tech for as little as a fiftieth the cost. Thermoelectri...

There are certainly clothes and wires that can transmit electricity, but wouldn't it make sense if they could hold on to it as well? Researchers at the University of Central Florida certainly think so, since they've just developed technology that lets wires and threads store energy. Their approach...

Solar panels have become cheaper and more efficient in recent years, but you can't say the same for the big, costly inverters turning their energy into usable electricity. Google isn't happy with this lack of progress, so it's about to launch the Little Box Challenge, an open competition to build ...

Many green energy sources only generate power in a narrow range of conditions. Solar panels won't work when it's dark, for instance, and wind turbines are useless when everything is still. If Solar Wind Energy Tower has its way, though, we'll soon get clean electricity around the clock. It recentl...

You can't buy a Tesla in New Jersey, but now you can Supercharge one up! Tesla's 100th Supercharger just came online in Hamilton, located just a few miles from the NJ state capital of Trenton. The Garden State's very first Supercharger sports six stalls, and, since it's positioned just a few miles...

If you're playing Defiance, you could probably use a bit more gun. The designers certainly thought so. As often as not, higher-rated weapons just weren't worth upgrading to compared to your older weapons with lower ratings. But that's not true with the next major patch. Your EGO rating will be a lo...

Solar power just hit the big time in the US -- BrightSource Energy has confirmed that the world's largest solar thermal plant, the Ivanpah Solar Electric Generating System in California, is up and running. The array, also backed by Google and NRG Energy, produces a total 392MW of power through 173...

Apple's original MagSafe connector was a simple, but revolutionary new feature for its notebooks. Its T-shaped design also hates being placed in a lap. The straight-out shape makes it difficult to rest a MacBook on a pair of crossed legs without snapping the charger out of place. The second genera...

We've all been in this situation before: You haven't plugged in your iPhone in a couple of days and now you have just a sliver of battery life left. Your phone has been warning you that it's near death, but you have nowhere to charge it. At this point, you don't care if your phone is the fastest o...

iOS 7 is all kinds of sexy, but with a slew of fancy new features comes more strain on the ever-important statistic of battery life. iOS 7 is compatible with iPhone 4 or later (though not all features are supported on older devices), so if you're upgrading your current device to the new operating ...

Google's goal of meeting its electrical needs with renewable sources got another big boost today. The Happy Hereford wind farm in Texas will produce 240 megawatts of juice, and all of that output has been bought by Big G. That power won't flow directly from the turbines into Google's data centers,...
