12V to 30V Car Voltage Booster

This is just conceptual and is not in any way something you'd want to try. It's very simple and doesn't have any protections. A good booster will have a low battery shutdown protection, also an overvoltage and current limiting, a few lowpass filters here and there and a short circuit protection (to say the least). The only good thing about this is that it doesn't draw a full current at no load condition, so if this were to be interpret as an amplifier class, this should be class AB.

Interesting though.

Seems Youtube had car generator or alternator without regulator doing different voltages at different RPM's lighting lamps or heating appliances with aid of voltmeter.

Super inefficient. Did you not notice the source current waveform and average level are just insane? Also, this is the kind of model where you cannot omit the series resistance of your working inductor and still expect it to perform realistically. Also, virtually all power mosfets include an integrated inverse parallel avalanche diode between drain and source. Although that diode may not always affect the circuit, it's usually a highly relevant consideration when switching inductive loads. A lot of the stuff you post is pretty sophisticated and often over my head so you may be rolling your eyes as you read this. Not trying to be a jerk, I just calls 'em as I sees 'em.
