Well, finally, a movie that shows that there is a cold-driven engine. this refutes a bit the current theory of heat engines, it also extends it to "cold" engines. So the Lord Kelvin's laws only work in a narrow range of reality .. Here, shown how a tightly corked plastic bottle changes the volume of soybeans as a result of pouring cold water on it .. So there is a vacuum inside it. This negative pressure can be introduced into the engine under a vacuum, such as in aviation pneumatic applications powered by negative pressure from the Veturi nozzle during the flight. and it is imaginative that, however, we can make such an engine, using a few bottles and valves, which all the time, when the cold comes to them, will give them a vacuum and the engine will rotate all the time. Here is a movie and the principles of operation of the engine on negative pressure. Well, maybe the global warming will not threaten us.
