If one were to make an injected, hypergolic, IC engine, you would squirt the fuel in at the top of the piston stroke; no compression required. You have a point to all this nonsense? -- Jim Pennino Remove .spam.sux to reply.

Just have the PVs drive a rotor coil, much like a car alternator, and pick up the energy with another set of stator coils. (separate from the ones that extract the physical motive energy, of course). You couldn't use that for your main rotor current, however, because then they wouldn't generate anything at night. Unless, of course, you put some batteries and a charge controller in your rotor, which seems to be growing exponentially. ;-) Cheers! Rich |
