I was wondering if you built a homopolar generator like the one Faraday did but built the main shaft and balanced it like a gyroscope so there would be little frictional losses, could you in theory build an overunity device.
I mean if you get a perfectly balanced gyroscope like that of one off of an single engine airplane that can spin for hours and in turn made a generator out of it,
would it build up a large enough electrical charge during those hours where you could then run it back into a battery, then discharge some power from the battery back into the generator itself to increase the rpm back up sufficiently as to produce more current to charge the battery and maybe have a little leftover as excess charge...
would there be any magnetic drag that would cause this to be impossible/impracticle???
I have tried to make this as clear as I can, let me know if I can clear anything up!

And yes, I DO KNOW THIS HAS NOTHING TO DO WITH R&S, BUT I THOUGHT I'D GET THE MOST ANSWERS HERE.
That's why I'm asking this question again...

over unity is not possible...
I've seen a simple driven pendulum design that is very efficient, using the magnetic field collapse on the drive coil to recharge the battery.
And I've seen a clock winder design that used atmospheric pressure changes for power... to the untrained, is appears perpetual.

There will always be loses. Friction is one, as well as core/copper loses. Also the battery wouldn't be perfect. All of this is based on the second law of thermal dynamics. You could overcome some by superconductivity, but that would take more energy than you would get. Maybe in the cold of outer space.
I worked with superconductivity many years ago with a particle accelerator. There were problems, so the next generation was going to room temperature.

the problem with an overunity gadget is that, on a similar time as you are able to decrease losses to an extremely small point you will no longer have the means to do away with all of them. additionally the performance of your generator would be under one, the skill will run out sometime. additionally the skill which you pull out of the generator for something is lost to the device. The gyro in a small plane is powered.

No. You ignore a lot of physics (everything other than friction which you write off). I quick terms, moving charges will take energy from the rotor.

Try asking whether god would approve of such a device... lol
