Re: How to build a set of spinning concentric rings? (Mass Relays, Gravity Drive, etc
correction: Perpetual Motion is impossible in atmosphere. Gravity is actually essential for many designs of 'perpetual' motion devices. Friction and air resistance is what kills them, not gravity.
Re: How to build a set of spinning concentric rings? (Mass Relays, Gravity Drive, etc
I want to build a set, too, although I'm doing it on a much larger scale and am planning to use stepper motors, LEDs, and slip-rings. However, while doing research to get design ideas, I did find a metal...
