A little information to show that a 500 pound flywheel could have easily run for 54 days using very little energy.
Years ago I made two small flywheels for a magnetic free energy machine I was working on. The wheels measured 6 inches and weighed just over 1 pound. I'll say 2 for this. They had a 3/4 inch bearing in the center and had 8 extending arms made from hollow, square shaped brass tubing, each terminating in a stack of 4 1 inch by 1/8 th inch magnets. Spinning them by hand, so they had an estimated spin rate of 180 rpm, resulted in their rotation lasting just over 8 minutes. Now, for these figures I am going to lean slightly towards the skeptical, in that a flywheel spinning at 90 rmp is going to actually spin longer than 4 minutes (probably closer to 5) since any increase in speed also results with an increase in air friction. But for ease I am only going to say 4 minutes. Also, with these paticular flywheels, they were not covered but were open further increasing air resistence, but wont take that into effect. So a 22 rpm flywheel is going to last for about 1 minute from first impulse spin. That's approximatly a loss of 1 rpm per every 3 secs. So...in order to maintain the wheels spin rate it needs an energy burst once every 3 secs. Now, a spinning flywheel needs far less energy to maintain its momentum than it does to get up to running speed, just because the only resistence it's fighting is friction, and not friction plus inertia. It was shown on Bessler's wheel, and quoted, that it turned easily from side to side when pushed by hand (which incidently to me shows it was not an overbalancing act since the wheel did not take off when this was done, but that's another matter.)
and john maintains it was started with a slight push with the fingers. As well, it is thought to be run by only five pound weights. These things show it to be a very well balanced flywheel. Contrary to what some may believe any increase in a flywheels weight or size is going to increase it's storage capacity. A wheel that is either double in size, or double in weight is going to double in how long it runs. As I stated these wheels of mine were 6 inches at 2 pounds
. Increasing the 6 inches to 12 feet results the 1 minute duration becoming 24 minutes. Increasing the weight from 2 pounds to approx 50 pounds results 24 minutes becoming 576 minutes, or 9.6 hours. An increase from 50 pounds to 500 pounds results a duration increase to 90.6 hours, or 3 days 17 1/2 hours of run time from first impulse. This means the wheel looses 1 rotation per every 3.4 (rougly) hours. This means the wheel needs an impulse every 3.4 hours to maintain it's speed. Since it is already shown that very little force is needed to set it in motion, and a lot less to maintain it's momentum, You'll see not much stored energy would be needed to keep it going. I am roughly estimating well under 1 horsepower ( I'll keep you posted). A typical microwave needs 1 horsepower to run. That means the amount of energy the wheel would have to have stored to be the equivelent of turning your microwave on for 1 sec. or to turn on 7 50 watt lights for 2 secs.
