No combustion happens in a fuel cell. It is literally an electric car in the absolute sense of the word.
632.
by _hypx 4y ago
No. There is no step where heat is an intermediate step. If you relax the definition of combustion that much, even batteries are combusting inside them.

Hydrogen is literally identical to electricity in this regard. It is as green as it's energy source.

by _hypx 4y ago
You're basically referring to noble metals and the like. We use them because they are useful in very small quantities. That's not the case with lithium.

by _hypx 4y ago
That is no different than a battery car. You are just shifting pollution to whatever is making your electricity. And if anyone comes in and says "I spent tens of thousands of dollars getting green electricity!" then it should be o

It behaves like one though. It is only found in low concentrations and never in pure form or easily accessible ores.

Not even close. At best something like LFP, but not the peak of li-ion. Stationary systems do not call for conventional batteries. They would be something else entirely if we are serious about the problem.

by _hypx 4y ago
Agreed. No one should think that there will be one language for everything and everyone.

Sodium-ion batteries still don't exist yet. And even if they do, they will be much lower energy density than li-ion. EVs will get heavier, not lighter.

A bunch of people immediately downvoted within a few minutes of posting that. I guess I struck a nerve.

You can get the same thing with a ICE car with a big engine. There's something specific about wanting way more power than you need but demanding that it happens silently.

Not really. Many of these cars are on lease, or bought on loans. Many people can pencil in the cost numbers and can afford it. Spending way too much money on a car is a classic American tradition.

We’re spending many hundreds of billions of dollars on new cars and charging infrastructure. This could easily be redirected to mass transit.

by _hypx 4y ago
Harm reduction would be driving less, not spend tens of thousands on a new car.

by _hypx 4y ago
Most EV sales happen in urban centers, not rural areas. Not to mention that battery cars doesn't really solve the problem for rural areas too, due to limited range, less charging infrastructure and much higher cost.

Bing doesn't seem any better than Google though. I was thinking of something that gives you a dramatically superior result than Google.
647.
by _hypx 4y ago
But what can replace Google? Is there another search engine with stunningly relevant results like the early days of Google?

This effectively means the end of the ICE ban. It's pretty easy to envision something like a PHEV powered by e-fuels. It will run on batteries much of time. Because of that, doubts about cost of fuel or production capacity won't r

That graph gets more stupid every time it gets updated...

That's mostly due to the lack of viable rivers left to dam.

It isn't. You read that wrong.

O3DE is just open sourced Lumberyard.
653.
by _hypx 4y ago
That's worryingly close to the same story high-end Unix providers told about Linux. If there is an open source engine that does 99% of what a proprietary engine does, then it's very likely we won't see that proprietary engine

Green hydrogen is a good idea, but it doesn't excuse us from coming up with alternatives. We still want more than one solution to tackle the climate change issue.

by _hypx 4y ago
And yet still cheaper than doing nothing. Same is true of half-solutions or pretend solutions. In reality nuclear is more than cheap enough to do the job. If upfront costs is really an issue, then we should subsidize it. And even with all n

by _hypx 4y ago
I'm going to come out and say, not even the last of its kind. Support for nuclear power is directly proportional to real, intellectually motivated support for clean energy (this is not related to the people that make dumb protests). An

Hydrogen storage is just a tank of gas. For most vehicles that will give you plenty of range. Easily >300 miles.

Battery swapping will utterly explode the amount of raw materials needed. It's going to be hydrogen cars simply because it is the genuinely scalable solution. The exact details don't really matter, so long as raw material usage is

The ideal solution is always going to be mass transit. But if that isn't possible, then the next best idea would be fuel cell cars. They are also a type of EV and therefore zero emissions, but unlikely battery cars they do not have the

Methanol fuel cells exist too.
