FWIW, Calculations show that this approach is twice as efficient as
a Zenon propellent "Ion Space Drive" (~ 5 amps @ 600 volts) and
68% efficiency as a Bladeless Microturbine (4 inch dia rotor @ 96,000 RPM).
Microturbines (essentially Turbochargers used on engines) are a big item
for distributed power generation these days. Some go as high as 120,000 RPM.
