Your old laptop's battery will light homes in developing countries

Don’t be too quick to toss out the battery from that ancient laptop – it might just be the key to powering homes in developing countries, and helping the environment in the process. IBM researchers have revealed UrJar, a device that turns old lithium-ion battery packs into rechargeable energy sources for low-power devices like LED light bulbs, fans and cellphones.

What a great idea. Places that accept batteries for recycling or proper disposal need to get clued into this.
