Don't use a generator, just use an RC drone/helicopter motor. Not hard to find one rated to 30k rpm, and it'll cost you like 100 bucks.
Dr. Mad Thrust Series Motor 4082 - 1400kv for 90mm EDF /8S
41000rpm
If you do some back of the napkin calculations, it should be able to pump out more power than a car alternator, you just have to step it down with a DC DC converter.
This is essentially a motorcycle or race car PM generator on crack. Those spin at 16000rpm and have a really good power to weight ratio, now you're just increasing speed and decreasing torque.
