Tesla turbine + shake flashlight

From the MAKE Flickr pool
MrfixitRick finds a new use for his CD Tesla Turbine, this time generating light via water pressure -
The Shake Flashlight Shaker is seen mounted on top of the Tesla CD Turbine, which is running on faucet water pressure. The CD magnetic coupling acts as a crankshaft with a copper wire connecting rod to the magnet in the stripped down shake flashlight. A second shakelight is clamped next to the first and is able to charge wirelessly by simple magnetic coupling of the neodymium magnets.

Here are my suggestions for improvement:
1) Have the light generated shine on a solar panel.
2) The electricity from the panel will then be passes through distiled water.
3) Funnel the hydrogen produced into a gas generator.
4) Have the generator power the water pump feeding the turbine.
You have just created a perpetual motion machine.

uhh, loss of conservation of energy comes into play with creating a perpetual motion device. unless you were to create a perfect machine, and have a perfectly frictionless environment incliuding gravity. and even a distance form stars creates friction.
oh wait that was a joke, okay i get it now.

Gab - that is the farthest thing from perpetual motion. He is using the force of gravity that the water has to turn a small turbine.
It is a good idea, but not perpetual. If you were to put one of these on your yard sprinkler, you could use it as a supplement to your solar electrical system. Everytime you run the faucet and dishwasher, you would get some electricity.
Water pressure is usually around 30 PSI, this is a lot of force to be exerted on a small turbine. Granted, you would loose a small amount of water pressure, but just skip the shower ;)
