Hamster-powered Light

If you look at hamsters, all they do is eat, sleep and run on the hamster wheel. Maybe you could (literally) make its life a little brighter by allowing the hamster wheel to power a small night light. A recent project added a low RPM alternator to a hamster wheel, allowing the hamster to power its own light source. Magnets were used to pass by a stationary coil in order to induce a current, though it doesn’t generate enough power to charge a battery, so your hamsterwill only keep its mini-sun alive as long as it’s exercising. You might not want to keep this hamster cage in your room, though.
