Here is my own concept of a heat expansion motor designed to be more efficient than the Minto's wheel which works on similar principles. the sonic water hammer technology was added to enhance the efficiency of the heat expansion rotor array.
nice done! just keep in mind how low are critical points for helium and nitrogen, u won't be able to keep them liquid at the temp where water is still in liquid form ;) . So just changing the working fluids and i see no problem with it making some turns.
BTW I just commented the wheel. Cavitation pump is an apart subject.
PS: i don't think it is capillary process, principle is quite different.
You have my attention, since you put your full name on this. :o
Here's the same link in your diagram of the first post. It's not clickable in the diagram, so I doubt many will take a look. Nice work btw.
