What is the fastest R.P.M. possible for an object such as a gyro?
Can the speed of electricty be achieved?
I have designed a flywheel type device that could achieve very high speeds. I am wondering if anyone has experimented with super R.P.M.'s or Rounds Per Second as I would see it?
I am thinking that at a certain speed things unknown to us so far would happen. Thanks for your thoughts on this matter.

When you say gyro do you mean gyroscope of gyrocopter?
- dental turbines run at 400,000 rpm [1]
- nanoscale silicon turbines run at above 1,000,000 rpm [2]
The parts fail when the tension due to angular acceleration is equal to or greater than the tensile strength of the part. That means that the max tension is related to molecular binding force.
If you are looking for relativistic effects the kinetic energy needs to be on the order of the rest mass. No known chemical bonds in matter can hold nuclear energy densities, or we could have a thermonuclear explosion internal combustion engine, and hot fusion power-plants wouldnt be a problem. Holding the rest-mass of a quarter would be 100 times larger than holding in a thermonuclear explosion.
Many perpetual motion machines (bad science) are based around angular motion, because the brain takes a while to build an intuition around that sort of thing.

Regarding Joseph G's answer, I worked with a functioning laser gyro at Honeywell in the late 1960's. See http://content.honeywell.com/dses/products/gyros/default.htm

Mechanical gyros are going to be replaced by optical gyros. Laser light running around in a fiber optic cable could be more accurate, and not subject to shock and vibration.

Hi. The fastest speed of rotation possible would be where the surface approached the speed of light. Any material know to man would have long since failed due to centripetal force.
