Developing green technology isn’t child’s play, but children’s games can certainly inspire new ideas. Playground equipment made from old wind turbines, and a solar powered night light are just two of this week’s green tech finds.
A couple of weeks ago, a friend tweeted out a question about recycling Tyvek™ envelopes. I responded that she could – if she mailed them to a location that accepted them. She was a little put off: after all, the envelope was marked with a #5 plastic recycling symbol, so shouldn’t she just be able to throw it in her recycling bin?
Refrigerate and cook food without electricity? We’ve got finds this week that get you pretty close, along with mushrooms that eat plastic, and plans to reuse dirty diapers (really!).
The DIY, electricity-free refrigerator: Ever heard of a zeer pot? This very old concept for keeping food chilled only requires two clay flower pots, and some sand and water to build yourself. (via @dothegreenthing)
And then cook that food without power: Well, not exactly, but with a lot less power. The Wonderbag keeps food cooking after the heat’s turned off, and was originally designed for very poor people who couldn’t afford much fuel. (via Inhabitat)
