This fully assembled Nitinol Heat Engine works like an engine without any visible power source. As a shape memory alloy, the Nitinol wire reacts to small changes in temperature converting low temperature thermal energy into mechanical energy and driving the engine as it tries to return to its "remembered shape".
The wheels of the Thermobile will continue to spin as long as it remains heated. To start the engine, simply immerse the edge of the smaller pulley into a water bath between 45 and 90 degrees Celsius and spin the larger pulley.
8" long x 1" thick, 4 oz.
