Just out of curiosity what supposed law of thermal dynamics is being broken?
And which methods of accounting for the energy exchanges are being used?
And catalysts are known for having interactive properties with chemical reactions yet they dont actually add or consume energy from the system themselves.
I am just curious.
As far as getting the low voltage higher current out of an alternator I already mentioned how to do it earlier in the thread.
Or as mentioned using a switch mode system would work too. Just use a buck converter set up if electrical isolation is not a problem.
