MIT students created water bottle light bulbs
that diffract natural sunlight and provide the equivalent of a 55 watt light bulb out of an empty plastic bottle, water, and a few drops of bleach. They are being installed and used in shanty towns where no natural light gets into the makeshift tin roof homes.

Recycle your computer junk.
A large US office supply retailer just became the first to offer everyday, in-store recycling for computers & other office technology, and will recycle them using EPA guidelines. Only $10 an item (smaller stuff like mice and keyboards are free).

Quite a good human interest story from yesterday's Guardian about what happens to clothes after they go in the recycling bin or off to the charity shop.
