    If you now rearranged natural Magnets on the flywheel and in a circular frame around it, so that it keeps getting constantly repelled, would you not be able to harness some "free energy" (well, convert some magnetic force into electric energy?)

    Could this work if you put the magnets on the outside of the flywheel 🤔 It would take more material but would it produce more current?

    You need iron or any feromagnetic material instead of air for the inductances cores, this is needed for the magnetic circuit to have low reluctance. With air coils the result is low voltage and current.

    To get more power why don't you just stack more "alternators" along the shaft.

    The magnetic design of this looks pretty inefficient. I think you'll get significantly better results with coil of this shape using thin round (coin shaped) magnets with poles on opposing flat sides.

    I wonder how much power you could get if you added a hand-crank to spin up the fly-wheel (of course, you would need a release to allow for it to free spin without the crank also needing to spin) :3

    To further reduce the friction, you can use also magnets to replace the pin at both ends. Then put the entire system inside a vacuum chamber

    You have a massive voltage drop from the diodes, regular diodes have a 0.7 forward voltage. That means with 2 diodes you already lose 1.4V! Shottkeys can decrease this to about 0.5V and Germanium diodes to 0.3V. Also depending on the quality of each. While synchronous rectification can have you lose almost nothing.

    Flywheel storage systems for vehicles have been developed over a number of years, the braking energy is used to spin up a (250Kg?) flywheel to over 10,000 rpm (in a vacuum to reduce windage losses) the stored kinetic energy is then recovered to accelerate the vehicle (usually a bus).

    Could you also constrain the axle with another set of repelling magnets at both ends? That way even the tiniest friction from the end of the shaft touching the end stop is eliminated.

    I really want to see this revised in 3 ways: - Correct the problem of the bent shaft so it can spin much faster and still be relatively safe. - Is it possible to add magnets *above* the shaft to give it more security? - Add some sort of mechanism that will allow you to manually spin it **WAY** faster. Basically the same as a bicycle in high gear. I don't know the specific name for the mechanism, but it's the one that allows you to peddle very rapidly and the peddles are basically "locked" on gear teeth when spinning in one direction, but if you stop peddling or even peddle backwards, the wheels of the bike can spin independently of the peddles. I'm no scientist or engineer, but it seems to me that if you were to do those 3 things, this device could actually have a practical application in the real world. Probably not an efficient way of generating electricity unless you think of the disproportionately costly input as being a small workout and good for your fitness, but this would be a really cool and fun novelty power source for a small light or other cosmetic machine.

    There are many "infinite energy backyard scientist" type people who think they've discovered some great thing when they learn how alternators work. They're just like "I'll use magnets to power it", and its like, you're just adding the magnetic equivalent of gears, you still need to spin any combination of floating magnets to generate power. I think it's good uneducated people are learning, what I don't like is they're often learning to support conspiracies like the government is hiding magnetic tech from us and going down the conspiracy rabbit hole.

    Serious noob question but how is the resistance working when he's just hot swapping those LED's? I.e. I thought the component usage had to match the output of the generator but he doesn't seem to add any resistance. Is it something to do with the fact he is using a capacitor?
