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

An automotive alternator is very inefficient.

Really, why is that and just how inefficient?.

It's inefficient because it's made to a price and petrol was cheap.

removes a parasitic load from the IC engine.
