Nitinol Heat Engine -
powered by hot and cold water.
The Heat Engineis a very special kind of heat engine that demonstrates
the conversion of heat energy into mechanical energy. Based upon the
work of Dr. Alfred Johnson who was granted a patent on this type of heat engine in 1977 patent # 4,055,955.
It uses the unique property of Nitinol alloy to generate mechanical
motion from heat. Nitinol has trained into a shape at high temperature
(about 600° C) and allowed to cool to room temperature, where it can
be easily deformed and welded into a loop.
When heated above a transition temperature (in this application about
50° C to 70° C) the Nitinol object abruptly returns to its high-temperature
shape with a substantial force that is able to drive the pulleys and
thus create motion.

Brass Candle Accessory for Heat Engine |
|
Replace the birthday candle on your magnetic heat engine with this brass candle that does not burn down like a wax candle. Simply fuel with alcohol and let it burn. Be careful, once lit candle becomes very hot.
