but this has nothing to do with an alternator using any kind of "free power". The whole concept you are presenting defies logic. If there was extra power available to drive an alternator using the same amount of fuel, is in contradiction to the law of conservation of energy. It does not happen.
I am not talking about defying the law of conservation of energy LOL
The little quotes: “ “ I used or italics are there on purpose.
When you run your car heater you are using “waste” as any heat or energy- alternator or heater- not applied to the work is ‘waste.’ An inefficiency.
Correct. The ‘free’ is not necessarily free. But the percentage load is - or can be- minuscule. In some conditions essentially not measurable by the gas gauge.
Argue if you want to but between Smokey Yunick and GM and I think even Toyota Tundras with variable valves and some other
current vehicles utilize methods to fractionally decrease fuel use by shutting down use when not deemed necessary.
This does not defy thermal or energy science. It points out that with trucks especially older or large RVs there is no
apparent consequences to running other equipment. This is due to either low percentage of losses or the power production of the motor in some flat or particularly downhill driving isn’t fully utilized or not at all. This is why ‘mileage’ races use coasting to gain sometimes HUGE fuel savings.
The second alternator isn’t doing some magic thing or defying the law of conservation of energy in any way- it just is a high likelihood of not visibly or
noticeably altering fuel mileage.
Nothing defies the laws of science. He wasn’t talking about laboratory conditions but was looking at possible ways of creating practical methods of creating hot water for several options of use.
Your diatribe above goes down rabbit holes of stuff I never suggested. Cylinder deactivation for example: how on earth did you think that was a free energy reference?? It was a reference to the fact that
at times during driving a distance in a vehicle all the possible power is not required. Tesla uses this concept, basically all e-cars use regen, and my 2021 nissan rogue company car has an incredible coast functionality.
Way, way back to Crower and Yunick and many others they knew about excess power. Yunick explored several things including high heat operations which virtually all vehicles today use.
There are no suggestions of energy science laws being broken in anything I wrote. Just the fact that you can run a second alternator potentially with no apparent consequences. Ymmv lol- pun intended
Thank you.
