Victor, do me a favor... you have trusted me this far, so trust me now when I say that it cannot work.
Electrical resistance is something technology has not yet been able to overcome. Yes, we can mitigate it, but not eliminate it.
Mechanical friction is another thing we have not yet overcome. We have magneto-fluid bearings, hydrodynamic bearings, and some of the most advanced lubricants to date... but friction still exists.
Is a "perpetual motion" machine impossible? No, I'm sure it isn't. Eventually technology will get there. What WILL be impossible is using that machine to do any sort of workload, because once you start taking energy out of that perpetual motion machine, it will slow down and eventually stop. If it did not, that would mean you are somehow siphoning energy from somewhere else... which again, isn't possible at this time. The idea of drawing energy from a so called zero point clean vacuum is fascinating, but likely unattainable, at least in our lifetimes.
Trust me now, Victor... you would be better off using photovoltaics and/or a nuclear power source for something like this - relatively simple, abundant energy that requires little to no fuel to be carried with you.
