In keeping with the old proverb that rolling stones gather no moss, this stationary table not only gathers plenty of moss, but gathers plenty of electricity as well, hacking into the photosynthesizing plants to harvest enough power to keep small devices like clocks charged up and happy.

Here at Dvice we've reported on a variety of alternative street lamp designs. We've seen kinetic powered versions and solar models , but this glowing green lamp is a first

There are plenty of places we are learning to save costs on electricity, such as energy efficient light bulbs and solar power . However, a new study released by Carnegie Mellon University highlights an area where we aren't so smart — electricity costs spent on game consoles are soaring, especially as they sit in idle mode.

Philips was the only entry in the Department of Energy's L Prize for designing a super-efficient light bulb, so I guess it's not really surprising that the company managed to win. But, Philips did manage to meet the DoE's stringent efficient criteria with its new bulb, and the result of their efforts is officially going to be on sale as of this Sunday.

The developing world has a continuous need for two things: electricity, and clean water. But more than that, there's a need for a decentralized way to produce both of these things, without a lot of additional infrastructure, and a new type of wind turbine that can suck water straight out of the air seems like the ideal solution.

There are solar-powered street lights and even trash-powered lamps, and now here's one powered by you and me.

Some of the metal sculptures in the Mr. Iron Robot theme park are over ten feet tall — and so what if they aren't official Transformers ?! These robots made out of scrapped cars and machine tools would definitely do in a pinch

The only way that solar power is ever going to contribute an appreciable amount of energy to the betterment (and cheaperment) of society is if we plaster solar panels on everything, everywhere, all the time.

Pollution glue may sound like a joke, but it is real and it's being deployed in London in a bid to clean up one of Europe's dirtiest cities . The glue is really a dust suppressant solution sprayed on some of the city's busiest streets to keep airborne particulates to a minimum
