EcoModo - The Best of Treehugger

This week, we have some unusual ways to recycle your cell phone, smart algorithms for a cheaper Internet, really smart cars that use only the cheapest electricity, and UFOs that clean water.

Recycle your phone by throwing it. Really! Check out 4 ways to keep your phone green.

Electric cars are already a greener option for automobiles, but what if they were also smart enough to charge up only when electricity is at its cheapest? Ford is looking to give customers exactly this with new charging software.

Speaking of cheaper electricity options, the Internet could become less energy intensive with smart algorithms. A new study shows how energy-savvy algorithms could switch traffic to data centers where the cost is lowest.

And finally, what week kicks off well without UFOs? Well, UFO-like objects, anyway. This very cool solar-powered water filter just hit the waterways of Japan.
