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. Most take around a 8 to 9 Hp motor to turn it when
charging. That is they take about 9 hp off the crank.
I think you've finally flipped. Use an electric motor to generate
electricity...
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.
Just do without one then. Who needs oil circulating in an engine?
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.
And all you need to do now is invent a way of turning waste heat into
electricity economically. If they existed, we'd be using them to generate
electricity from the sun, etc.
well to be fair that's how a nuclear power station works..

All heat engines are inherently inefficient. Heat is an intermediary
in most processes.

Its not inherently inefficient any more than anything else is.

Ineptocracy

(in-ep-toc’-ra-cy) – a system of government where the least capable to
lead are elected by the least capable of producing, and where the
members of society least likely to sustain themselves or succeed, are
rewarded with goods and services paid for by the confiscated wealth of a
diminishing number of producers.- Hide quoted text -

Creating heat can be 100% efficient.
Turning heat into anything else is the big problem.
