"That's the worst misapplication of basic thermo I've seen in a long time."
Is it now? Well, just make sure you wear a good pair of walking shoes when you buy that new electric vehicle.
You might bring a thermodynamics book to read along the way, so you can figure out where you went wrong.
Electric cars are only off by an order of magnitude (on the short side) from being actually comparable and viable vehicles - on cost and performance.
If you simply do not want to compare like vehicles, then why not go the rest of the way and just ride a bike everywhere you go?
Well, why don't you just tell me where is it you think I went wrong? I'm an engineer, too, always willing to learn.
