This ignores the part where battery powered cars have existed for over a century and have "failed." But recent events have changed the needs of society, and now they have "succeeded." People are now claiming that this ca

Yes. The fact that hydrogen fuel cells are technically a type of battery, meaning that there is no rationale for why it can't do that. Hence why "efficiencies" is just an excuse. In fact, this entire argument is a made-up o

So where is this battery chemistry with even higher energy density? Or comes from a resource more abundant that water? The answer is none that we know of. These are self-evident reasons why we should spend significant resources pursuing thi

Read what I said to the other guy. We are not having a conversation over whether those problems exist. It's about the motivation to solve them. And the problems of today should give us massive motivation to do so. Even trillions of dol

That is the excuse I'm talking about. We are not having a discussion over whether those problems exist, it is about whether we should spend money on tackling them. After all, we are at in dire need of a battery with higher energy densi

Ignoring the high cost of batteries and the environmental harm in building them. You can eliminate pretty much an entire class of storage needs and all the cost that portains. Heck, even pumped hydro doesn't really need to exist if you

Then why not pour billions more? We are talking about the potential end of the world, and yet we also proclaim that this cannot motivate us to spend an amount of money that is a tiny fraction of what we spend on military hardware.

It's weird that people have failed to notice that hydrogen has an atomic mass of 1. Far better than both of them. To quote what I said elsewhere: > It's bizarre how people refuse to accept that hydrogen fuel cells are technical

There's an element above lithium on the periodic table that has an even lower mass per unit of charge. Weird that no one talks about this. Also repeating what I said elsewhere: > It's bizarre how people refuse to accept that hy

If you have many petawatt-hours of hydrogen storage, you don't need batteries at all.

Hydrogen fuel is basically here already. It will be used for grids shortly. And saying that it will be 2080 before it happens is the same thing as saying no (real) climate change policy will happen until 2080. Even Tesla admits we will need

The problem with HDDs is that they're not keeping up with Moore's Law. I remember buying an 8TB HDD years ago at nearly the same price as current 8TB HDDs. If there were 32TB and 64TB available now, the argument over HDDs and SSDs

Synthetic fuels and hydrogen. You're just being closed minded.

I mean in total, there are >1 billion. Annual is something like 80 million per year. The point is that BEVs do not have any kind of commanding lead. Not to mention that there's nothing stopping people from moving from BEV to FCEV. I

by _hypx 4y ago
And over a billion ICE cars... Not to mention that if you go back a handful of years, BEVs were in the same boat as FCEVs. Like I said, all of this is selective reasoning and doesn't prove anything. And you're still ignoring my po

by _hypx 4y ago
That is all very selective reasoning. You literally ignored what I just said, in that batteries have huge resource issues and that could force our hand. In the end, there's no coherent reason why one (and only one) type of EV must win.

It's worth noting that just because something "makes sense" doesn't mean these types of bets are going to work out. I'm reminded of Japan's similar bet on computing: https://en.wikipedia.org/wik

You do realize that BEVs predate internal combustion cars? You could've said the same thing about all EVs just a few years ago. The problem with BEVs is that they have gigantic resource requirements. It is very much replacing one probl

by _hypx 4y ago
I hope people realize that fuel cell cars are also EVs, and have only a handful more moving parts to deal with. People have mislead themselves into thinking the BEV is synonymous with all EVs. This type of thinking could easily lead people

I find it very hard to believe that much of that won't just move to south Asia or southeast Asia.

Just FYI, the latest Prius Prime is functionally identical to the Chevy Volt. It just costs a lot less (starts at $33k). GM simply failed to design it properly.

Guys like you are totally deluded. BEVs are the real dead end and waste of resources. It is just replacing one unsustainable idea with another. And it can't even meet the driving needs of everyone anyways. All car companies will inevit

The plan admits the need for hydrogen and synthetic fuels. It has moved on from trying to solve it entirely with batteries and renewables alone.

Again no. Catalysts are endless recyclable.

by _hypx 4y ago
No, since sometimes it is also just iron or whatever. Not to mention that a catalyst is a surface, not a volume. You can get away with atom-thick layers of catalysts. Which is why even with platinum you only need a few grams of it. Cost of
