Ocean Wave Power Generator Demo
Unit |
|
A while back, a Discover Circuits
visitor wanted a simply way to demonstrate how electricity could be generated from
the up and down movement of ocean waves. The system was to be part of a science
fair project, showing different renewable energy sources.

I gave this some thought and came up with the system
shown below. It uses a simple plastic foam float attached to a lever arm, which is
connected to the shaft of an inexpensive stepper motor, available from
www.jameco.com. The AC voltage output of the stepper motor was connected to a
few Schottky diodes to convert the signal to DC. When properly mounted in a
tank of water, the motion of a wave in the tank causes the shaft of the stepper
motor to move. That movement produces enough electricity to turn on the visible
red LED. |
