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.

Truly a study in inefficient power conversion!

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

WOW. This is great.

Any one trying to do this experiment. Let us know and tell us how well it goes.

Aw! and if your in need of flashlights then here is where you can get them from. http://www.super-cool-gadgets.com/shake-flashlight.html
