Alt text:

An idling gas engine may be annoyingly loud, but that's the price you pay for having WAY less torque available at a standstill.

An interesting article about the Muskmelon, Tesla, and fuel cells. []https://energynews.biz/will-tesla-release-hydrogen-car/ (take the article with a spoonful of salt I think) It's perhaps another attempt at a pump and dump stock fraud as he does need money for twitter. But, I've seen a couple of these blurbs lately and I can't find where they originate from.

Even the ketamine wonder wants to sound like he thinks Tesla is going to abandon pure EVs and build and sell something with a hydrogen fuel cell evidently. If so,and you can't rule out it out completely yet, the ICE engine might not be done yet - just swapping a fuel source.

A fuel cell generates power through an electrochemical reaction, not combustion. So no, even if we went to hydrogen fuel cells, the ICE engine is done.

But you will burn the hydrogen to release the energy in some form. That would seem to indicate some form of combustion would it not?

Fuel cells don't burn the hydrogen. There is no combustion.
