Hi Argentina, and Isarmann
It would be great if you find a thermal modeling program to evaluate the turbine action, and share with the forum, your findings.
It is my thinking that, the compression of air you mention above, has to be a part of the turbine's energy cycle or you have too much loss outside the system.
A closed loop system should look exactly like a heat pump, with the turbine acting as the expansion valve, and giving it the ability to expand and contract the space between the blades, while turning, is important to the pressure/vacuum buildups.
So many things can be done with the basic design, it is good to see experimenters looking at Tesla's idea.
