Solar Power Water Bottle
Some of us geeks like to travel around with our own water bottle (also to be used for other liquids).
And for those geeks I found this cool little toy. It is a 32oz. water bottle but it has a solar panel in the top and when it gets dark just press the switch and you have light for hours and hours. And it even has two colors of light first there is white and that one takes the most power from and then there is red and that one uses very little power so you can leave it on all night so that you know where you drink is.
I believe that this bottle could be the ideal camping tool even when you are just camping under your desk at work.
