4F30.10-2 - Stirling Engine with Generator
To demonstrate the energy conversion of light and heat to electricity to power an LED board using a stirling engine.
Attach the Stirling Engine assembly with parabolic reflector to the tripod assembly. Use 2 banana cables to connect the LED board to the generator outputs. For operation outside, this is all that is necessary.
For lecture hall use, set up the 750W light bulb on a scissor jack with a variac. Place the assembly at the focus of the mirrors from the Light the Match demo. Be sure to squeezee clamp the large mirror down. To position the stirling engine, have the reflector be centered in the beam from the 750W bulb. Then move it in or out until the black paper ring is entirely illuminated by the light from the mirror across the room. If it is not entirely illuminated, the Stirling Engine will not work.
Turn on the 750W bulb to about 15% of its power. Walk over to the Stirling Engine to make sure the black paper ring is being illuminated by the source. Then turn the 750W bulb up to about 60%. Bump start the Stirling Engine to get it to begin running. Observe the LED light bar illuminate from the power generated by the Stirling Engine.
