Before I continue: batteries are barbaric technology. Many things to choose from, but not light weight or low volume.

Also: I don't see a NEED to combat CO2 emissions. CO2 is the breath of life, without it, Earth turns into the Moon, Mars or Venus like places. Stuff needs to grow and nothing does without CO2. 3 or 4 parts per 10,000, that's not a whole lot. Greenhouse farmers buy CO2 and injects it into their farms to boost crop growth, add harvests per years. Food prices are high, people DIE of famine, CO2 is needed, not the enemy. Climate was never stable anywhere and isn't stable on any planet we known with an atmosphere, not even now. The last true climate change we had, was in the 12th hour of homo sapiens and most people who preach climate change don't know a thing about it, what species were extincted or how super recent that catastrophe was, let along what caused it. Odd, because the extinction of only large reptiles, 5000x longer (yes, you read that correctly) ago, everyone seems to know about in quite some detail...

Non-CO2 exhaust gasses I'd love to see reduced, they seem to not have the same critical uses for Earth?

Better still that charging or swapping would be topping up during a drive. There's a project that worked on 20 kW in-road-surface inductive charging that works while driving at highway speeds. If enough main corridors are equipped with that, and cars with compatible charge loops, there is no longer need for large batteries.
Smaller PHEV batteries that suit communiting and rarely starting the on board ICE would actually suffice even for long distance driving. Just follow long distance highways, like most everyone does on long drives.


In Formula 1 racing, they have a unique device called MGU-H. I can't pretend to fully understand it, but it's a generator on the hot exhaust gasses that puts energy back into the drivetrain either via the battery or by spooling the turbo. I am really fuzzy on it. This MGU-H brings around 80 kW non-stop that would otherwise have floated away as heat and sound. Yes, it makes the car less loud.
Combined with a (weak) hybrid system that is greatly flawed by small battery and regulated deployment per lap, these F1 powertrains still achieve >50% thermal efficiency.
Regulation have limited the fuel flow and battery size, so teams work on efficiency a lot to go faster.


Sadly the MGU-H is deemed useless for road cars as it needs concentrated heat and exhaust flow to work. I'm not super convinced. Perhaps a small family car could have an exhaust system that optimized for the kinds of flow an appropriately sized and tuned MGU-H calls for, and still return a few kW, which would be pretty significant for cars that use around 5-10 kW in everyday urban driving and 20 kW on the highway (where the MGU-H would work better).

So batteries are barbaric and fossil fuels are smart, got it.

Why do you think they call oil a fossil fuel? ie a fossil?. For example, if you found a dead road kill that's been out in the sun for weeks the stinky black slimy goo pooling under the carcass is basically oil. In fact, the oil producers mine dead plant/animal graveyards similar to our graveyards. So when you fill up your car your literally burning the residue from the dead for fuel.

So when people talk about fossil-fuels I get this image of one of those B rate horror flicks where a bunch of brain dead zombies are running around eating the dead and burning them for fuel like cord wood to stay warm. I mean burning dead animals for fuel is kind of fubar and as barbaric as it gets and yet this is exactly what were doing. Does that sound intelligent?.

I'm still surprised any of these people can say they "love oil" with a straight face. When people say they love fossils fuels I see the picture below. It's just so absurd and barbaric a person has to laugh otherwise we would lose our mind.

Hey I'm not the one making stupid statements like batteries are barbaric and implying climate change is a hoax and not a problem because plants like CO2.
