Anyone with a house and an EV can do it. I don't have an EV yet but some friends just stayed for a week with a rented Tesla, and charging it up in the garage every night worked great, even with just a regular 120V outlet available.

> Anyone with a house So how many people is that? Don't estimate house ownership or house rents on your circle of friends. What about cities, apartments with no means to install chargers? World is not urban sprawl where houses have garage and power available for charging cars.

70% of Americans live in houses:

It's less populist and more a talking point. It's the perfect cover. "We can't stop allowing the rich to destroy the climate because we care so much about poor people." In '35 it's doubtful ICE will be cheaper than EV anyway (look at price development over last decade...) Banning ICE will speed up this development. Climate change will disproportionately affect people who are already vulnerable. Tax carbon emissions a…

ICE prices will continue to drop. SSD hard drives (the newer, more efficient and faster technology) prices have plummeted in the last 10 years, however spinning rust prices have also plummeted, making spinning rust the only choice if capacity-per-dollar is your metric. You also mention climate change, but I don't see how an extra average degree of weather (if that materializes) will be worse than stripping poor peopl…

You're the one dreaming.

The US is fundamentally incapable of building public transportation? Ludicrous. What's required is political will.

ICE prices will not drop faster than EV. It's much more mature technology.

If forbidding new ICE cars (in 7+ years) "strips people of transportation" we clearly need som kind of subsidies to alleviate that.

Climate change is a threat. It's not just something people talk about because it's fun. The current estimates predict 3 degrees of warming until the end of the century. That's assuming we stop burning fossile fuels some time this century. The disruption this would cause to agriculture and living conditions around the world are just staggering. If nothing else, consider the costs of 2 meeters sea level rise until 2100...

Preventing climate change is a cost saving measure.

Why would anyone want to use e-fuel in 2035 instead of electricity? (Except for "luxury" brands that just want to be special to distinguish themselves from the rabble.)

I'll still be driving my land cruiser in 2035.

The ban is for new vehicles so that's not relevant.

Someone should do a followup on all the batteries break-troughs on the front page of HN over the last 5 years and count how many got into production. Still, an announcement from a big company like this is a lot more credible than from research labs or small start-ups, IMO.

I follow these announcements with a sense of dread, as battery limits are the main obstacle between our current situation and widespread adoption of drones and robotics for military use.

I've got Civic e:hev, which has kind of similar setup. ICE does drive wheels in some situations (high speed, much power required), but mostly is just EV. It does not even have a gearbox, so there is only direct coupling from ICE to the wheels that can be engaged or disengaged (this is done automatically, you have no manual control over this). I really like this setup, because it gives economy, but also a range and I…

Isn't Honda the dark horse of hybrids? I remember riding in one and the owner explained that apparently Honda chose a hybrid architecture that was different that everyone else. The car's transition from electric to ICE was quite noticeable.

I don't know how it was, but on the current setup you literally (in the literal sense of the word) feel nothing. The only differentiator is "EV" indicator on the dash.

Even with a car, you aren’t necessarily regulating millions of individuals - primarily just manufacturers. I suppose there is the odd case where “old joe” removed his catalytic converter and is polluting more than others but that is probably rare. I don’t get your point on centralization however - more efficient but less robust (just like in software).

Correction - I do get your point

For necessarily centralized industries like car manufacturing the regulations are written to protect the wealthy incumbents competition more than to protect consumers.

Current mass produced batteries, which tend to hover around 260-300 Wh/kg. Higher density (but still under 500) are available, but in far smaller quantities for a very high cost. The exciting part of this announcement is that if anyone can scale manufacturing, it is them.

The real question is, will this lead to reduction in cost? If yes, I hope they open-source it so that the fight against global warming can gain some momentum across the globe.

Cost is just one of the interesting dimensions. For various kinds of transport energy may be more important than cost. I would be prepared to pay significantly more for an EV if had range of 1000 km rather than 500.

Why does going lithium mean 18650? 14500s have always existed. I think there’s even smaller than that but I haven’t personally checked in a bit.

Form factor smaller than 1865 with energy dense formula is rare. Chinese made LFP but only a handful of mfgs make them anymore. So size doesn't matter, but it basically matters :D

LFP is going to be manufactured in north america soon

Same with jet fuel on a plane. They calculate the amount to fuel carefully to be efficient but safe. Too much and the plane is heavier and uses more fuel. Too little and you might run out if put into a holding then diverted. Obviously jet fuel is what it is it wont get more dense but a more efficient engine means less fuel needed means even more efficiency and so on.

It was something I had never considered but it is wild to think about. I believe it was Vaclav Smil that highlighted it to me. On its longest trip an A380(I think?) takes off weighing 400 tons and lands weighing 200 tons. That kind of thing is just cool to ponder.

I realized while working on heavy transport aircraft that they their weight can be (very roughly) 1/3 aircraft, 1/3 fuel, and 1/3 cargo, and being struck by how different these proportions are from the family sedan.

> I’m afraid these bans get systematically sabotaged by well funded ice lobby groups. Nonsense; it's just harsh reality landing on green wet-dreams. They effectively propose a ban on cheap cars, and you expected ... what, exactly? The only way they're replacing ICE vehicles is by making the EVs cheaper, and there is a limit to how high they can tax sales of ICE vehicles or fuels without a population revolt.

"The only way they're replacing ICE vehicles is by making the EVs cheaper" Even if electric cars would be cheaper, faster and longer running - some people would rather die, than give up their ICE cars and motorcycles. The strong lobby in germany against banning aren't the poor, but the rich who want to drive their roaring Porsche till eternity. They literally say that. I can somewhat understand the appeal of an loud…

those will still exist. they will just become ultra luxury, like bugghatis today
