Scientists have long talked about black silicon (that is, silicon with nano-sized structures) having the potential to trump conventional solar power, and there's now some proof that this is happening. Aalto University researchers have developed black silicon solar cells that achieve a record 22.1 ...

Back in November, SolaRoad launched a test bike path that generates energy through solar cells embedded in the concrete. It sounds like an outlandish idea, but it's apparently paying off very quickly. The company has revealed that its road has generated much more energy than expected -- it produce...

The standard line about solar power is that while good in theory, the technology just isn't there to keep our lights on and our Netflix streaming. But a new study from MIT (PDF) suggests that's not the case. According to the massive report (an epic 356 pages) current crystalline silicon photovolta...

However much you may like grilling food on a warm day, you probably don't like dealing with gas tanks or other typical grill hassles... and most solar cookers won't help much if it's overcast outside. The upcoming GoSun Grill might be a smarter way to handle those backyard shindigs, however. It ca...

Here's an electric bike that doesn't need plugging in.. or swapping out batteries. As the name suggests, the Solarbike has solar cells built into both sides of the party typical bicycle wheels, using cells (and a design) that's apparently "shadow optimized": The inventor is based in Copenhagen, ...

While you're just about to head to bed, over in Abu Dhabi the Solar Impulse team will attempt to fly around the world, powered by solar energy alone. While the plane takes off today in March, it won't likely return until late July, early August. The route will take in the sights of India, China, N...

Apple makes much ado about using clean energy sources to power its buildings these days, and it just put its money where its mouth is... a lot of money. The company is investing a whopping $848 million in a First Solar plant in California's Monterey County that, according to Apple chief Tim Cook, ...

Think the load of Bluetooth speakers announced at CES is rather ho-hum? Well, Braven has something to say about that. The company's new BRV-PRO Bluetooth speaker sports the rugged look we've come to expect from them, and claims 20 hours of battery life on a charge. Those are easily the two least i...

Solar power just hit one of its biggest milestones, in more ways than one. First Solar recently finished building Topaz, a 550-megawatt plant that represents the largest active solar farm on the planet. And we do mean large -- the installation's nine million solar panels cover 9.5 square miles of ...

If you're a cyclist, you know the anxiety that comes with running out of water in the middle of a bike ride -- the last thing you want is dehydration when you're miles away from home. Design student Kristof Retezàr may just set your mind at ease, though. He recently developed Fontus, a bike...

It's great that manufacturers recover lead from discarded car batteries to use in new ones, since lead production from ores yields toxic residues. The problem is, when we shift from lead-acid to lithium-ion and other types of batteries (and we're starting to), over 200 million old batteries could ...

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...

What's a fairly low-powered solar panel going to get you on a 600 horsepower car? Plenty, according to Aston Martin, which is set to install one of the roof of a Vantage GTE race car for the World Endurance Championship. The luxury car company said it's not looking at thin-film solar "because it's...

Right now, you can install relatively cheap technology on your own roof and power your house, gadgets and even your car. For free! Sorcery? Not so much. The Earth receives more energy from our sun in about one hour than humans consume in an entire year. That's why solar power was the second leadin...

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...
