Note, in this next video we only had a few hours to test our prototype at the wind tunnel and we didn't figure out until a few days later, that when we taped down the wires to the three-phase permanent magnet generator, we were locking up the axle because of its built-in overspeed protection.  The generator is directly connected to the flywheel, which is why it wasn't exactly flying...  We figured that once we get it working smoothly then we'll measure it's power, but the illusive mechanical issue was never solved and we ran out of time.
