Crikey. An alternator is actually a very efficient device. Sounds like
they're clutching at straws.

NO, using waste heat to produce electricity . Run a 100A alternator off an
electric motor.

Eh?, Where or what is powering is err umm rotary converter system?..

Most take around a 8 to 9 Hp motor to turn it when charging.
That is they take about 9 hp off the crank. Remove that, the mechanical oil
pump, water pump, a/c and replace all with electric and the fuel consumption
rises, as the parasite hp suckers are not sucking off the engine. An oil
pump alone can consume 10hp off the crank.

Then a smaller engine is needed reducing fuel consumption yet again. All
simple stuff that can be done tomorrow.

Parasite engine ancillaries can take one third of the HP from an engine.
Removing them and having a mechanism that charges the battery by waste heat
and kinetic energy is the answer to make these useless inefficient crocks
last a few more years before EVs take over fully.
