This video is about Nitinol memory metal engines that are basically Stirling heat engines and work on a very low temperature difference.
This technology can be easily scaled up into the KWatts range and drive a power generator to generate 50 or 60 HZ AC power. If you use solar power via Fresnell lenses to heat the hot water bath you can convert this heat energy into mechanical motion energy and then use a generator to generate 120 Volts 60 Hz AC or 230 Volts 50 Hz AC power.
Too bad the oil industry killed this invention also as it did also kill the electric cars !
In this report it is said, that 1 KWatts would require 600 US$ investment for the engine and that it is cheaper than PV and Nuclear power and this was in the 1970s. With todays alloy technology this price could be dropped dramatically and this would be a very cost effective technology.

It was a major threat to the oil barons as is proved in this documentary. So where is all of this hidden technology now?

This Shape Memory Metal (Nitinol) engine is driven by hot water!
You may recall the famous Thermobile, created in 1985 by Frederick Wang. The Heatmobile is a similar design, although offered as a simple self-assembly kit. It is essentially a heat engine that demonstrates the conversion of heat into mechanical energy. It uses the unique property of Nitinol alloy called the “memory effect”. Once Nitinol has been formed into shape at high temperature (about 600º C) and allowed to cool to room temperature, it can be easily deformed. However, when heated above a transition temperature (in this case about 70ºC to 80º C) the Nitinol object abruptly returns to its high-temperature shape with substantially more force than that required to deform it when cold.
Heatmobile uses a Nitinol wire formed into a closed loop that drives the two connected wheels. However the high temperature shape of the wire is straight. So when the bottom part of the wire loop is heated by the water, it tries to deform into a straight shape. This action provides a torque at the bottom wheel, and causes it to rotate. As the wire goes up around the top wheel, it is cooled by the air.
this is how to make a thermal electric generator using nitinol wire and copper.
