MIT students modified an exercise bike so it can power your laptop.

The next Tour de France winner may very well be the tech nerd from your IT department if MIT's new invention makes it to the mainstream. Taking a page out of the "GZ PC-Sport and Power Stepper" book, students modified an exercise bike so it can power your laptop.

The device works with a bicycle wheel attached to a generator, which in turn charges a conventional car battery. A 12-volt cigarette-lighter adapter is then used to hook up with your laptop. This prevents overcharge and fluctuating current damaging your PC.

This also begs the question: Does one have to pedal like a madman just to check e-mail? Not really, as these researchers discovered that only 30 watts are required to charge a notebook battery, and the average person can generate up to 75 watts continuously.
