Here's one idea which may provide a non solid coupling between Compressor and Turbine. The use of magnets? The magnets not being in direct contact ...the idea was a micro-turbine which starts up as a motor -jet (electric motor to spin the compresor) but there is a magnetic coupling to the turbine stage if this makes any sense. I've not seen a miniature motor jet powered by brushless motors and lithium batteries However I see no reason for there not being such devices but to add a turbine which was linked possibly using electromagnets then there could be possibilities to excercise control of the amount of regenerative feed back to the compressor?
