“A quick google search shows that gasoline has an energy density of 12,200 Wh/kg, “

Anyone with even a basic understanding if thermo engines knows that most of that energy is lost to heat and not available to power the car.

EV are worse but their inefficiencies are upstream of the consumer, so they don’t, like, even exist, amirite?

Yet it is virtually free cabin heat whenever needed. Heat that doesn’t drain a battery in the middle of a blizzard on I-95 stuck just a few miles outside of DC for 12 hours. We can agree that the heat by product eats up a lot of the energy capacity difference but you aren’t suggesting it eats up the WHOLE 24X advantage, are you? THAT! I’d find difficult to believe, frankly.

Ice efficiencies range from 20 to 35%.

So even at 20% gas has about 5 times the usable energy density than the LA battery.

Just the facts.

Current gasoline engines have a thermal efficiency of about 40% (40% of the energy of the gasoline gets turned into motion), with some experimental engines getting to 50%

Coal-fired electric power plants average thermal efficiency is also around 40%

And then you have to account for transmission-line loss, and loss from charging the battery (you don’t get 100% of the power back that you put in)
