Is green electricity suppose to be nonviable now? If you can accept that green electricity, which will be the dominate source of unexpected cost, is going to be very cheap, then anything predominately made from it will also be very cheap. T

As free as green electricity itself. You're just reusing the same attacks that were used against wind and solar.

by _hypx 3y ago
Same issue with wind and solar. Sure, you have to build them first, but afterwards it's a continuous stream of virtually free energy.

You are describing e-fuels. Hydrogen from excess renewables is the same idea. The critics are simply not paying attention to the fact that green energy is nearly free and therefore fuels made from it can also be nearly free.

Agreed. This is the generic pro-battery car screed, but now that non-fossil fuel alternatives are becoming viable, this argument is "fighting the last war" so to speak. As the cost of alternative ideas come down and also drop in C

There will be a hydrogen refueling network. People are simply being too short-sighted.

That might eventually happen. There's a reason why we have natural gas piping in millions of homes. With hydrogen this even replaces the need for the grid. Many ideas that were originally laughed at end up being the winning solution.

It's seriously time to start thinking about shutting down CNN. What's the point of a third infotainment channel? If anything, A 24/7 news channel itself is an outdated concept and needs to die.

The same rules apply for smaller pipelines. It's highly likely that it is cheaper to build hydrogen stations fed by pipelines than high-power cables for DC fast charging. Trucks can work as last-mile distribution too. This is not nearl

You are the same type of person who goes around and asks why pro-nuclear people are so unwilling to change their minds. The answer is simple: They are not unwilling change to their minds. The problem is that their opponents are simply wrong

Wrong again. With modern advancements, you can conceive of electromagnetic system that can do this at low cost and with no complex mechanisms. This is just another anti-hydrogen propaganda argument, and is based on willful ignorance of what

No. Embrittlement is easily solved by choosing the right alloy, or coating everything with a protective coating.

Except you wouldn't build it like that. Even "on the spot" production will still significant hydrogen storage and distribution. It's not like you can place a giant tank right next to each piece of machinery. This are sti

We will need hydrogen anyways too. Not unless you think all of industry doesn't need to exist. Hydrogen can be delivered via pipeline just like natural gas. It is actually cheaper to move hydrogen around than electricity this way.

Regulations can change. Windows can be replaced by LCD screens. As long as the pilot isn't making wild maneuvers, passenger comfort should be no different.

And if you don't have a home with a garage to charge your car? How do apartment dwellers charge their car? And the rest of your post is bullshit. You want a centralized system that can meet all refueling needs by itself. And as we make

That is wrong. You can make hydrogen at home. You only need water and electricity. People are simply imagining advantages of BEVs. That said, there is not much need for home hydrogen production. It is better to have a more centralized refue

You’re own anti-hydrogen tirade is equally ignorant. A fuel cell is an electrochemical system just like a li-ion battery. It has more or less the same basic pros and cons. This includes efficiency, and we can expect eventual parity between

The “battery” of the future will be something akin to hydrogen fuel cells. You eliminate all significant raw material requirements while still having an EV. The problem is that it is highly disruptive to the current trend of BEVs with giant

This the basic idea behind hydrogen fuel cell cars too, only with a fuel cell instead of an engine. The goal is 100% zero emissions with 100% the functionality of existing cars. It is also why existing BEVs are almost certainly a fad. After

There's basically zero battery swapping stations too. We are trapped in an obsession with charging stations. It will be remembered as a form of tunnel vision. Hydrogen stations will exist in vast numbers once this tunnel vision breaks

You could do the same thing with hydrogen and make your own fuel. It is fully possible and is being ignored out of battery hype.
477.
by _hypx 3y ago
It is immediately obvious that the refueling solution is the best one because you neither need the vast resources of battery swapping, nor long recharge times.

Which is funny because Internet forums used to be a software package you acquire and run on your own servers. No one really asked for a centralized system where you didn't have any control. It seems pretty straight-forward to go back t

Helicopters are VTOLs. And all VTOL concepts have basically the same aerodynamic problems. So no, it is incredibly unlikely these problems can be solved easily. Which is why VTOL concepts have stayed vaporware. People are simply trying to

You might as well ban cars entirely at that point. The biggest criticism of EVs is that they are still cars. They are still the most resource and footprint intensive form of transportation out there.
