An engineering team at the University of Arizona have made big strides in making solar energy cheap for everyone.

NASA and other scientists believe that they have found a new planet on the edge of the solar system, inside the Oort asteroid cloud.

The Sun has generated the first X-Class solar flare of Solar Cycle 24. While this will be an opportunity to test the radiation resistance of our satellites, for us on Earth it simply means that we could be treated to a showing of Northern Lights.

A team of scientist at Purdue University takes a biomimetic approach to engineering solar cells, appropriating the components of living systems to novel ends.

We’ve seen solar-powered laptop cases and even a crazy Apple patent that suggested sun powered back lighting, but this is a concept that could change computing as we know it. The “IMEC meets Howest” is claimed to be the first laptop which relies completely on the power of the sun. Energized by two solar panels, no electricity source is needed ...

Now that you can control your NXT robot with your Android phone, rather than using yet another electronic device, there are ways to save the planet even further, thanks to Dexter Industries’ dSolar Systems. The 9V solar power system allows you to rig your Mindstorms NXT robots for harnessing the power of the sun. The solar system provides about 250 ...

If you had the chance to build a contraption that would provide you with green internet access almost anywhere, wouldn’t you take it? This DIY WiFi Repeater needs absolutely no electricity to function, yet extends your reach into the cloud by a significant amount. Solar panels power a Linksys WRT54G v8 router with 7.5 volts at 500 milliamps in direct ...

Batteries eventually need to be replaced. That’s the way we’ve been living for decades, so shelling out the cash for batteries just seems like something we have to do. The SunMod Modification Kit ensures that you’ll never have to replace your batteries again. For a very reasonable $20, SunMod turns any of your AA or AAA battery powered devices into ...

Resembling some sort of Steve Jobs’ approved sunflower, Mac Funamizu’s iPetals is an elegant and fun method of charging your iPhone through the dasterdly power of the sun. Harness those UVs! Yeah! Dig, dig, dig! Excuse me for that outburst. I knew I shouldn’t workout right before I post.

Al Gore, Barack Obama and now, there’s you. Trying to save the planet isn’t always an easy job, but somebody’s gotta do it. Well, these Christmas lights actually are pretty easy. The solar panels do all of the work. All you have to do is hang the lights and enjoy. Not only do you get to save a butt load ...
