Maybe it's the matter of how many words you write, like in legal documents :) anyway, what i was saying is that different circuits may be used after the generator. Linear wouldn't make sense due to low efficiency, but on the other hand switching circuits tend to keep power constant, which may have all kinds of effects. | |

With a simple rotating PM alternator voltage increases approximately linearly with RPM, tailing off as various secondary effects become dominant. For a constant current load - such as would be seen if a linear regulator fed a constant resistance load, then load power increases linearly with voltage. For a constant resistance load (no regulator) load power increases as load squared and current linearly. Energy is the time integral of power and is not overly relevant in this discussion. | |

| Jul 7, 2019 at 7:53 | comment | added | Russell McMahon♦ | Gregory - try again :-) -> As he suggests that RPM is liable to be up to 20x the speed at which the required energy will be generated the odds of the load choking the source is small. If load is resistive then power increases and decreases as square of V . V is liable to be about proportional to speed. So at say 50% of speed load is 25% of required or less. | |

| Jul 6, 2019 at 1:30 | comment | added | Russell McMahon♦ | Gregory - based on what he says odds are that the enery hatrvesting is not the main power consumer. "Choking" the power source mechanically sounds both impractical and undesirable. I may be wrong :-). | |
