What is the energy requirement for this device? What little research I 
did (in the past) indicated that you needed a trunkfull of batteries to 
sustain this device, and still needed to do intercooling (same as if you 
supercharged)..  even though you are proposing it for takeoff only...

If you want something that is ONLY for takeoff, I'd go the nitrous 
route, like one of our members has done with his amphibious rotary 
powered Coot.
