My plan to buy an EV in the next five years may be realistic after all. Happy!

You may not have a choice in the matter as more and more countries are thinking of/implementing ICE bans in the near future.

We do have a choice because, on paper, we do have a choice in choosing those countries’ politicians. I know I’ll never give my vote to a politician keen on banning gasoline cars.

It’s sadly also true that the technocrats actually taking those decisions are a lot less directly accountable, but nothing that a second “yellow vests” movement won’t be able to fix.

They're unlikely to succeed because if the massive tax on poor people (ICE bans) actually gets implemented, all of the poor people who are forced to buy an unaffordable EV will vote for populists promising to unwind the bans.

They’re only banning sales of new EVs in the short term, and poor people don’t buy new cars anyway. By the time they are buying EVs, they’ll be much cheaper.

and then in Germany right wing/neoliberal politicians run around, make smug faces and tell people: ooooh, we need e-fuels because those combustion engines, they are sooooo good, the chinese are envious and will just copy (yes. for tanks...). During their reign: - solar industry: gone (in the 2000s germany had everything, domestically produced) - wind energy: gone (well, Siemens did it themselves too) - existing domes…

It's ridiculous to dump these failures on the right wings/neoliberals. The actual government (and past governments) should take responsibility for the dumpster fires.

"CATL has announced a new “condensed” battery with 500 Wh/kg which it says will go into mass production this year" This is a lot more credible than most of the battery stories, because CATL is already producing a ton of batteries, lending them some credibility. This is a little under 2x the density of current batteries.

> battery with 500 Wh/kg

Wow, that's amazing, creeping up towards the energy density of gasoline at around 1200 Wh/kg

Of course you don't have to lug around the spent gasoline after you've used it, but that's really the problem too innit?

Not banning per se, just stopping sales of new. So there will still be plenty of used ICE cars knocking around for a good few years.

Key numbers: They doubled Wh/kg from about 280 to about 500. I assume that thinking about battery capacity form first principles, the theoretical limit is reached when the charged battery consists of 50% matter and 50% antimatter, right? Then during discharge, the reaction between the two would turn the matter/antimatter into energy. How would that stack up against the 500Wh/kg stated here? Update: Did a bit of googl…

Ridiculously higher. One gram of matter converted to energy (matter-antimatter annihilation assumed to be 100% efficient) yields, using E = mc^2 and 3.6x10^6 Joules per Kilowatt-hour, 25 million Kilowatt-hours

500-600 Wh/kg is the target for replacing average flight durations. Fuel is one of the highest costs for an airline, so eliminating the majority of that will make the demand for any viable options go bananas, even with a much higher upfront cost. Being seen as 'green' is a big bonus for the airline.

If the tech takes off (pun intended) every major airport will need a SMR. Which is maybe good? But politically impractical today .

With the energy efficiency attainable by traveling in the upper atmosphere, this might be the greenest possible long range transportation.

God such a tantalizing solar punk dream. I would love just to hear the inside of an electric commercial airliner at altitude.

At least in the U.S., poor people buy used cars, while existing and proposed ICE bans effect new car sales. Any real economic effect will be delayed until after the ban, and in any event they'll still be buying used cars. I suppose used EVs might end up costing more, but they might end up costing less. Also, the immediate effect of bans might actually be to create a glut of cheap, used ICE cars.

None of that implies less risk of a populist backlash, though; not for any class of 'mericans, rich or poor.

Could you help us understand why you would like to keep buying gasoline cars?

(Edit: I see that you are being down voted. Perhaps elaborating on your desire to continue to be able to buy gasoline cars might help clarify your position better)
