It's Earth Day, of course, so there's a ton of green blogables out there. Here's a rousing overview of bright green gizmos:
Ever since the first Earth Day in 1970, a steady stream of inventions and gadgets have been popping up to help make the planet a little bit better. The old brick in the toilet, which saved a brick's worth of water with each flush, eventually gave way to today's low-flow models. Stand-alone solar panels have been integrated into systems that let consumers actually sell excess power back to their utilities.
Small wonder, then, that this year's Earth Day is a high-tech affair. From superefficient home appliances to recyclable razors, new ideas to save the planet are quickly coming on the market.
