Will there be gas stations, though?

And will there be enough power stations to generate all the electricity?

How much more generation do we actually need. For one, charging typically does not happen when the grid is at peak load, so a lot of spare capacity is available. Second, it takes approximately the same amount of energy to refine a tank of gasoline as it does to completely charge an EV, so it'll be a wash.

And yet we claim to live in a science based society. I mean, there are a million things, that do not need universal standards, but standards are imposed anyway. But where one standard would be really helpful, like scientific values, we have many. And some people would rather go to prison, than adopt. (I think that happened in the UK, after they force switched to metric)

Not only they might go to prison, they may risk values and lives of others, too: https://usma.org/unit-mixups

Well in a general sense, yes, but the particular case I remember was a (fish?) seller at a local market, so nothing life endangering.

I believe that current car racing trends will paint a picture of the future of automobiles. The hybrid area is among us, and the technology used is so well thought out and advanced. Hybrid as in “go incredibly fast”, and not “save gas” like as with a Prius. Currently in F1 and the new prototype classes, they are using electrification in conjunction with the internal combustion engine to create more instantly availabl…

that seems very unlikely to be honest. Commercial cars are sold first on reliability and operating costs, which is why Americans are shying away from buying cars that have a basic turbo and prefer larger gas engines instead.

This is completely false lol.. Which Americans are shying away from turbo cars exactly?

Pretty sure Ford and GM have an entire lineup of fuel efficient turbo cars out right now. Ford has the ecoboost engine line, so I’m confused on what data you are looking at?

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

I’m afraid these bans get systematically sabotaged by well funded ice lobby groups. Just look at what happened to the EU’s ice ban for personal vehicles. Spoiler: while new gasoline burning cars are technically banned after 2035 it will be completely legal to sell new gasoline burning cars by labelling them e-fuel only…

> 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.

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.

What battery pack that I can buy right now is 300Wh/kg? Sincerely curious because that's 50Wh/kg above what people are using in some very expensive UAVs.

Very expensive UAVs use lithium polymer battery packs with continuous discharge rates on the order of 80C and above. To get higher energy density, look for lithium ion battery packs or lipo packs that reduce discharge rates to trade off for long-term storage capacity.

Compare to the discharge rate vs. energy density tradeoffs of plug-in hybrid EVs versus battery-only EVs: A Chevy Volt PHeV has a 16 kWh pack and 87 kW motor, a Chevy Bolt has a 65 kWh pack and not a 65/16x87=350 kW motor but 149 kW.

You didn't cite sources for the critical pieces of that (the first three numbers). You also assumed that the battery is 100% lithium, which is obviously wrong. A random Googling says closer to 62kg. And now I'm tired of bothering to fact check you. I'm also going to say that all the car companies, battery companies, and governments in the world probably took six seconds to do basic math before investing trillions of…

The 62kg is a valid point. I have revised the calculation and added the citations. The problem still remains (at the global level).

> The problem still remains

It doesn't, because that 88,000,000,000 is a lower bound amount of lithium on the planet not an upper bound.

If I count all the apples on the apple tree in my yard, I haven't counted all the apples on the planet. Only the applies I know about. There's probably still more apple trees out there!

That 88,000,000,000 figure also doesn't count any lithium in the oceans. Taking even a small fraction from there would make that 88,000,000,000 seem tiny.

No, not for another ~15 years and then I'll still be able to buy ICE car. EVs in current state are not so good and what's even worse new ICE cars are becoming shittier and shittier because of restrictions imposing on them

You should buy what works best for you. But if you really believe an EV is not better than an ICE car in nearly all objective metrics, you are doing yourself a disservice.

I think you should read up on what ICE bans in countries where they are implemented actually means. Hint: You can continue to use the ICE vehicle you bought in 2034 in the EU until infinity.

> You can continue to use the ICE vehicle you bought in 2034 in the EU until infinity. Sure, if you can find fuel. By 2034 EVs will be enough of the market that gas stations are already closing (remember today new cars are 10 year old used cars, and there is every reason to think EVs will be half of all cars). There is still one on every corner, so you might not see this trend, but it will be in the statistics. By 20…

> Sure, if you can find fuel.

Of course you'll find fuel; ICE trucks aren't being banned. You can use their fuel.

Might be slightly inconvenient to have to drive to a depot once a month, but people will do it if the economics are right.

I think the age of Rube Goldberg dinosaur fumes fire machines is over and the age of Maxwells Equations is upon us. It’s sort of like college physics progression I just realized.

Do you believe that Saudi Aramco is just going throw their arms up and be like “well, the dinosaur fumes era is over everyone! Pack it up.”

The two technologies of electric and combustion are going to coexist with each other.

The rebirth of F1 into this new hybrid generation, as well as the new dPi hybrid prototype class will prove to you that Maxwells Equation is not close, and we breaking a new era of acceleration, braking, downforce, top speed, and fuel efficiency.

I just realized how much energy efficiency is being squeezed out of a Tesla. It's incredible. A normal diesel fueled sedan such as the Chevy Cruze diesel runs at about 31mpg, which is 13.2 km/l or 15.3 km/kg. Diesel has a mind-boggling 12700 Wh/kg energy density[1], which translates to an efficiency of ~827 Wh/km for the Chevy. By contrast, the Tesla Model S, has a ~540 kg battery[2]. At 272 Wh/kg (from the posted ar…

225Wh/km is very high. I see more like 140-160Wh/km driving 80-100km/h on a M3.

At a continuous 80km/h on a level road in the summer I can get down to 160Wh/km even in my 2015 S 70D. I have a friend with a Kia Eniro and he gets similar numbers to you most of the time.
