Though I wonder... Some decades ago people made similar arguments with regards to C/C++ versus native assembly. That the only way compiled languages could approach assembly languages on performance was if the code was written in a way

That might've been true at the time. But what about today? Can't we use the higher settings for JPEG 2000? At least speed shouldn't be an issue now.

You should be aware of the death toll for the construction of the first transcontinental railroad. It's not something we can legally replicate.

Hydrogen is viable anytime you need (or want) a chemical fuel.

Electrolysis of water. We'll have more than enough.

Summary: Both dark matter and modified gravity are true. Could be caused by wave-particle duality.

We're frankly headed towards a USB type-D standard, where we intentionally create different ports for different uses. A dedicated power connector should never a data connector, and there should be a way to differentiate A/V ports

It has the advantage of allowing us to avoid investing in any new manufacturing facilities or new production lines. For some cases, it makes sense.

A process that has both huge losses and requires enormous amounts of energy.

The pressure vessels are arguably safer than either batteries or gas tanks.

You don't combined the hydrogen with anything until the moment of reaction.

Of course, no such article ever points out that hydrogen-air batteries already exist and have a 40,000 Wh/kg energy density.

The other issue is recyclability. Modern li-ion batteries are basically superglued together in order to maximize energy density. A pack designed with recycling in mind will have to be more easily taken apart and likely significantly heavier

That's just pure delusion. Hydrogen is much easier to distribute and store than electricity. So much so we're talking about creating hydrogen as a way to generate electricity. Unless you think BEVs are the "final car," a

Carbon fiber tanks are much less of a disposal/recycling problem than batteries.

Someone once made the comparison that CFLs are BEVs, in the sense that they're weird compared to what we're use to and have major disposal problems. LED might a similar relationship to fuel cell cars since they work like the old k

https://www.pv-magazine.com/2020/06/16/hydrogen-storage-in-s... You can store hydrogen in underground salt caverns. We could store years' worth of energy demand.

This type of government/corporate collaboration is similar to how other traditional industries like autos, oil & gas, steel, etc., usually operate. That's because the capital cost of building factories and supply chains exceed

Yes, but you can create it during one part of the year and store it for other parts of the year. It is going to be a viable replacement for fossil fuels for northern climates long before nuclear fusion happens.

(Chemical) hydrogen will be available much sooner than fusion. We should see a lot of hydrogen related infrastructure being deployed soon.

Hydrogen is likely to replace BEVs eventually. Just like internal combustion manufacturers are stuck in their paradigm, so are EV makers.

Japan has a much better mass transit system and a culture that does not embrace the automobile like the US has. Plus, Japan has far more access to fresh water that California does. And Tokyo doesn't have that many skyscrapers. In fact,

That's a bit of a stretch. You would to rethink how American society works for that to happen. Everything from water use and automotive dependency would have be reconsidered. And since this is earthquake country construction is relativ

Hybrids are facing real challengers from a combination of PHEV, synfuel, hydrogen combustion and hydrogen fuel cell. While it is the ideal car of today I wouldn't be so sure about the next 20-30 years.

You're likely to hit a hard limit to what battery energy density can reach. The next step will be fuel cells which don't have the efficiency limits of traditional internal combustion.

ICEVs will outlast BEVs. Just like it did 100 years ago.
