You asked.
It looks to me as if the first idea was flawed due to overunity, or almost overunity, thinking.
The drag effect on the magnets is due to the power they are making in the generator.
Power comes from somewhere, and it takes power to make power.
The magnets only have 'drag' if they are making power.
Making power means power is moving.
Moving power means losses.
Losses mean it won't work.
If it takes 250W to move, and 250W is supplied to the generator, then the 'moving thing' will stop. Watts are used up in the generator, bearings, etc. It will not keep moving by itself. Losses to run the thing are greater than just running the thing by hand.
Otherwise, we could use a weedwhacker engine to power an alternator, and the alternator to make a lot more power than the weedwacker engine,
Then a DC motor to run some alternators, which make more power, fed to larger motors, repeat, repeat, repeat.
Then there would be plenty of powr to have a DC motor can replace the weedwacker engine, then we can all sell power back to the electic company.
We'll tell everyone who would do the same thing we did.
They will send everyone $100,000 a month.
We'll all be rich from what the electric company pays us.
And nobody would need the electric company, except to mail us those checks everybody is getting, and the money they send would be coming from the poeople who didn't hear about this wonderful device we all have.
It is possible to make a terrawatt at 250RPM. It will weigh a lot.
