If it's going to run inside a sealed enclosure won't the warm liquid cause enough humidity for not to run because it won't evaporate? Would you need to apply heat or just ambient temperature difference between the "head" and "belly" is enough to run on its own?

Something like the minto wheel?

Yes, it is the same sort of principle. They are heat engines.

So is a rubber band stretch it and it heats up, contract it to its original size and it can cool less than room temperature.
Make a wheel and use rubber bands instead of spokes and focus a hot bulb on one point in the rotation and it will start to rotate, it's just a gimmick like the bird

I guess we will never know how tinman did it. Oh well, moving on.
