Innovate or Die

First of all, seems like a pretty graphic title but sounds like a great competition. The device I found to be most practical and useful was the ipod charging stationary bike. It is a very simple design, but could be useful. It is very unlikely anyone will be biking long enough to completely drain the power in your ipod, except for Lance Armstrong, but it is an easy way to get a good workout and atleast maintain your battery. It is doubtful anyone would actually by the product, but a cool idea nonetheless.
