Engineering Explained posted this video where they go through why ICE engines are going away anytime soon. As they usually do in their videos they make a very compelling case.

I'm curious to hear what everyone thinks about this.

The highlights of the video for me are the energy density comparison and where they break down the cost for manufacturers.

HIs analysis looks sound. This is a bigger problem for aircraft than for cars as more frequent stops and power storage weight are both possible in cars. Of course, time to charge becomes another important factor he doesn't really get into. These are tradeoffs BEVs will continue to have until energy density goes up significantly, probably requiring a new battery chemistry.

While ICE fuel is more energy dense, a lot of the energy produced is wasted during the combustion process (friction). Much of the energy produced from petroleum cannot be used in a productive way which is a big downside of ICE, along with the inability to recapture wasted energy (braking). It is very important to also consider operational efficiency, not just energy density, when comparing the two.

He does, just not in that video. He posted another one about a week later where he also takes efficiency into account. Still not looking pretty for EVs :LOL::
