Does anyone make a small 500 + volts DC generator. Amps can be just milliamps. Size of a tractor generator.

They are called tachometer generators.
Typically 50Volts/1000 RPM. But you can get higher voltages than that. This site says up to 200Volts at 1000 RPM. To get 500Volts, you run it at 2500 RPM. The voltage is directly proportional to the speed.
If these are too small, you could also buy a 500VDC motor and energize the field, running it as a generator. You can usually get them with 150 / 300 Volt fields. They also make them in permanent magnet fields, but only rated at 180Volts @1750 RPM. You would have to run at 5000RPM, which might not hold up.
Rectified 120V Ac is about 150 volts.

electric fence charger on an inverter?

use an inverter to make 110 ac, then use a 1:5 or so turns ratio transformer with a 120vac input voltage to make ~500 volts. then rectify the voltage and filter to your needs. Easier than doing it with a different rotating device. Jim

Thanks. That is interesting.

It would need to be belt driven like a tractor generator.

It has to be a steady voltage like a battery pack.

google gogyropower.com to see where it is needed. Thanks.
I tried to watch the video, but I almost fell asleep waiting (and wading) through all the quotes that state how great this guy is.
Unfortunately I never did get to the part of the video that actually demostrates what he is trying to prove.
But by the name gryopower, I assume he is trying to set a body in motion and keep it in motion. i.e. Newtons law of motion. This works great in theory but not so well in principle. There is not such thing as "free" energy (conservation of energy).
Are there any videos that demonstrate his theory?
Sorry if I sound skeptical, but if it sounds too good to be true it usually is.

This is very easy. Get a transformer 1:5, take the secondary run it through a bridge rectifier then add a big capacitor.
You end up with clean DC. This is probably $20 worth the parts from Radio shack. Make sure the diodes will carry the amps and the capacitors are rated for the voltage.

Well, if you watch the whole video , you will see what is going on.
