Here is a little gadget to show your support for green energy. The solar powered Keychain LED light gives you light when you need if you expose it to some sun once in a while.
The Solar panel on this keychain is very small, but the 3 white LEDs just do not need much juice.
The Hong Kong based Gadget store Brando sells the Solar keychain for $9.50.
