No. Still way too heavy for airplanes. “Short-haul” is still 1,000 miles or more, and energy density is still too low to do that practically. Also, metal-air batteries gain weight as they discharge.

The other issue is that metal-air batteries go by another name: fuel cells. You are power-gated by how much oxygen you can deliver to the battery. As a result, metal-air batteries/fuel cells are either very slow to discharge, or have b

This is only a partial joke. It could really happen in a real airplane someday.

Practically no competing energy storage idea is going to be as cheap. With hydrogen, the only raw material is water. Nothing else can claim that they are utilizing resources that plentiful.

And what are you doing, but vigorous handwaving about how it is actually possible? Make a working version of it, or point to someone making it work. So far it is nothing but a paper concept. Again, no one is saying it is impossible. It is m

Again, your idea is vastly more complex. It falls in the same category as aerial battery swapping and global spanning vactrains. Sure, it could be done, but under any realistic scenario, it is not going to happen. It is far more likely that

Now it becomes doubly complex. The is both an self propelled vehicle while also able absorb many MWs of power from lasers or whatever. Sorry, but you are one fantasizing here. Everyone can imagine what this is. You're the one who actua

Again, we are talking about grams of such materials per fuel cell. All of which are readily substitutable. Meanwhile, all of the materials for batteries are in the kilograms, up to hundreds of kilograms for larger vehicles. Many of which ca

A wavelength that doesn’t penetrate the troposphere will make it impossible. You don’t seem to take your own idea very seriously… You are confusion implausible with impossible. Sure, it is not “impossible.” It is just absurdly unlikely. I m

None of these materials are really that limited. Not even nickel at the scale you’re imagining them to be. Remember, we’re looking at grams of such things, and they can easy be swapped out with some other material. Also, you do not need a c

Capitalism works because it can find an alternative to the resource that is running out. Something centrally planned systems struggle with. And a big reason why centrally planned systems fail is because they are usually ruled by conservativ

And if the beam fails, everyone is expected to die? Nevermind the feasibility of such a beam. These are highly implausible ideas. On the order of aerial battery swapping. You can imagine such things, but they won’t happen in any sort of pra

Neither biofuels nor batteries will ever make sense for airplanes. In the former, it is because it is basically an inefficient way of turning carbon dioxide into fuel. If we need liquids for airplanes, it will almost certainly be some kind

Those are not necessary. Solid oxide fuel cells use neither. In the long run, PEM fuel cells likely will use neither too, or very little (on the order of grams per fuel cell).

Peak oil will be "solved" by humanity moving away from oil. It is not solved by drilling for more oil, even though it allows for a temporary reprieve. My personal opinion will be that shortages on battery related materials will be

And the real concern is what other fields of research have this level of fraud or dishonesty? What other foundational research papers are yet to be outed as fake? We need to look at all fields of science where a decade or more have past sin

People can say that in hindsight. But no one in the early to mid-1800s believed that oil seeps implied anything significant, or that oil was a plentiful substance. It was a geological curiosity at the time. Most people had no idea they even

Should be noted that natural hydrogen was also known since antiquity: https://www.sciencedirect.com/science/article/abs/pii/S00128... The problem is that no one cared or knew what it was. This is not t

Again, the point is to not ban any kind of car as a redundancy . You've created an elaborate narrative of what you suppose your opponent is claiming. It is time to stop.

by _hypx 4y ago
But oil blockades won't stop the production of new ICE cars. A battery-related blockage will stop new car production. That would be a big crisis for automakers.

There will be some EVs in that scenario. Enough to tide things over. But in a world with only one option, anything that blocks that one option will destroy the whole car industry.

The point isn't to be invincible. If you have a diversity of cars, any one kind of embargo will only harm a portion of your car market. If you mandate only one type of car, then an embargo can completely stop your ability to make new c

The saving grace is that there could be alternative options. But the law should allow for even more options, such as eFuels. The way it is written is not particularly open-minded or designed in a feasible way. 2035 is not very far off for t

Did the alternative suddenly become banning all EVs? No, the alternative is to not ban any type of car. Unless everyone attempts an embargo all at once, you will have backup options in that case.

You will need millions, and that includes a vast number of fast chargers plus grid upgrades.

The infrastructure may never materialize. Not to mention that the amount of EVs may never materialize, as they are hugely dependent on raw materials and can be subjected to OPEC-like embargos. It could easy turn into a vast market of used c

In that scenario people will just keep their old cars for far longer than what the planners are imagining. Like Cuba which still operates cars from 60 years ago. The danger is then you have a society dominated by very outdated cars and a gr

Millions of people in Europe don’t have garages or easy access to charging stations. This policy is basically impossible in the near-term. The bet is that somehow in 12 years all of this gets solved. There is a real chance that ends up bein

That's pure gibberish. Just some marketing propaganda with zero evidence behind any of it. In reality, batteries are not sustainable and need vast amounts of raw materials to exist. Hydrogen vehicles lets you avoid this. That is a fund
