Ummm . . . Interstellar?!
I got an idea of placing two coils almost touching the aluminium rim and wiring them somehow obscurely with capacitors (how people do in wind power plants with squirrel cage motors nobly relabeled as "self excited induction generators") so they would prime themselves and start generating. If it works with cyclic asynchronous motor it should work with a linear one too, shouldn't?
In what way is it self-priming? Given a large enough, flat plate dynamo, I'm sure one could exploit the Earth's natural magnetic field. But, a small dynamo the size of which is suitable for a bike would never have sufficient surface area for electrical generation, no matter how fast it's made to spin. Remember that energy is neither created nor destroyed -- if it's self-generating, it has to draw energy from somewhere. Traditional alternators draw this energy from shaft rotation. Where is the self-excited generator drawing its energy from?
1) Reproduce the electricity meter configuration with externally driven 2 coils from relays, one 90deg after the other (the wheel should turn). This is how trains and roller coasters with linear motors work so I guess it should work.
This is basically a coarse-grained stepper motor as I currently understand the configuration.
2) Drive the wheel manually and see on a scope if the contraption really generates more energy than it eats
It will never do so. If it *looks* like it is, it's because it's drawing energy from multiple sources. Remember, with the laws of thermodynamics, you can't even break even -- you always lose. -- Samuel A. Falvo II
