Volkswagen have been experimenting with thermpiles in the exhaust to

Crikey. An alternator is actually a very efficient device. Sounds like
they're clutching at straws.
An automotive alternator is very inefficient. And not having it

A parasite gives nothing in return. An alternator is a commensal or
symbion. It turns mechanical energy into very useful electrical energy.
