Gyroscope used as a generator |
| Question: |
I have read in several places that gyos can be used as electric generators, what i dont see are output estimates. Just how much net power can be produced? Any links to related research would be appreciated. |

| | Gyroscopes can beused to give kinetic energy to an object, but the amount of friction created in trying to convert it to electrical is stupid. I've got 1volt at about 100mA from a gyroscope about 4" in diameter, not much.

| | IT is called a homopolar generator...
Best link regarding this is at: http://depalma.pair.com/
It explains why it work and this type of device it is not really known around because it omits relative motion of magnet/wire which is usualy needed to have some induced current regarding pto the faraday's motional EMF- law (wire moving trough a mag. field)...
It even sopose to produce anomalous output power (overunity effect) but there is no courage in the peaople doing that kind a research to look into that phenomena little bit more in detail there is no satisfactory explanation of the phenomena up to date...
Some peaple claim they solved that problem but there is no evidence fo me to tell you that is true ( www.distinti.com ) solving a faraday riddle...
The truth is there is inertial force inside a rotating object (centrifugal force) that might make some yet not studied effect on magnetised rotating conductor...

| | Gyroscopes are not used as generators. Flywheels are used to store energy which is generated my other means. A flywheel would behave as a gyroscope if it were allowed to, but this would be dangerous: the French telephone system power-supply was backed up by a flywheel and it had to be kept in a pit in case of unbalance or bursting. The homopolar generator is a well-understood (by physicists) device. However, because 'schoolboy' rules (flux-cutting, flux-linking) do not apply to it, certain crackpots have wrongly imagined that it does not obey the conservation laws. Its gyroscopic properties are irrelevant.

| | The only use of a gyroscope as a generator I've ever heard of is by using the earth's rotation to create precession in the gyroscope and then capture that precession with a regular generator. I'm not sure this is would actually work but who knows. You would need to bump the gyroscope off axis slightly whenever it aligned itself with the earth's axis. Also to be practical, it would have to generate enough power to keep the gyro going and still provide a reasonable amount of excess power. This is by no means free energy (although it would seem free to you). The use of such a generator would slow the earth's rotation by some miniscule amount.
