That has already happened with buses. There is much less range loss compared to battery buses: https://www.sustainable-bus.com/news/the-effect-of-cold-weat...

It should be a huge motivation for hydrogen cars, which are also EVs but without such weaknesses in cold weather. It is very unfortunate that the article just dismisses this idea with just one sentence and zero explanation.

The article is just a big fantasy. It makes the fundamental mistake of assume current trends will just continue into the future without regard to technical limitations. People have at various times made similar predictions about how diesel

If you're referring to nuclear, that only happened recently. Before, environmentalists had done more to stop zero emissions energy than to promote it. Geoengineering is likely to be the same type of fight. We pretty much have to do it.

Europe is buying Russia's natural gas. That is the root problem. In fact, with the shut downs of nuclear power, Europe is more dependent on natural gas and coal than it had been for decades.

Why do you think Europe is importing so much natural gas in the first place? What Russia is doing is a symptom of the problem. It is not the problem.

Doomerism is catching on because nearly none of those ideas are worth a damn. It's something of an subconscious realization that most environmentalists are not serious people, and most policies are intended to placate the electorate ra

"Never" is a strong word. People do need it every once in a while. You are taking the idea that people don't drive that much too far. The point is that the convention BEV is not that desirable, and that people will never acce

1,000 mile road trips actually happen, and until recently it was never a problem we had to deal with. I very much doubt we will ever get over it. We are specifically asked to abandon a feature we enjoyed for a century. We will likely only g

Because of how California taxation works, there are good reasons to have a 5 year rolling tax window and set budgets based on that. That would give us a much clearer picture of real budget surpluses and deficits.

Maybe. A lot of grades of steel cannot be made from scrap metal. At some point, you have to be able to turn iron rust in new steel, even if that rust comes from old steel.

That's steel recycling, not production of new steel.

The most prominent alternative (fuel cell EV) are also EVs. There are no fundamental downsides in comparison either. To continue your EE analogy, you're betting against another kind of CMOS which also happens to be made of far cheaper

FYI, 40 miles is not plucked out of a hat. Scientists specifically mention that number because it exceeds the daily average driving distance of >90% of people. It is basically the point where any further increases in range becomes unnece

If you mean battery EVs, it very likely won't happen. I would even go as far as saying it cannot happen. They are highly resource dependent and too expensive to make. Hydrogen EVs make significantly more sense once you realize renewabl

No one needs to bother with that race. It is just a ploy by China to gain marketshare in the car industry. It won't work because it ultimately creates a massive new resource dependency. One that just happens to shift everyone's su

The other companies are wasting their time. Battery EVs are a dead end and they will all have to move to hydrogen tech eventually. It is the other companies that are way behind.

It is also unfortunately a sign of a market imbalance. There have been periods in history where one company or group of related companies held a ridiculously large percentage of stock market capitalization. They rarely last for long, and in

Agreed. Long-termism isn't real and is just an excuse to ignore currently existing problems.

Grid connectivity is not magic. It will cost trillions to pull off and it still doesn't solve the problem of intermittency beyond daily fluctuations. Overprovisioning is just wasting energy. It also guarantees a free source of energy f

You will inevitably need storage capacity of weeks or even months. Especially with regards to seasonal energy shifts (e.g. solar power generated in the summer but used for heating in the winter). There is no prospect of batteries pulling th

That's the same argument used against solar, that it is too inefficient. It's also greatly exaggerated, another thing it has in common with solar. Fuel cell systems are electrochemical systems and can be easily improved beyond tha

Some companies are playing with fire by charging so much. A notable example is Nvidia, which is basically crippling its own lineup with their weak specs and high prices.
