Your own posting history suggests a BEV fanatic. And the fact you keep on bringing up biofuels show how unserious you are about the topic.

There will never be a long-distance battery powered plane. Not with any kind of battery we can conceive of today at any rate. And again, biofuels are not green.

When they actually start producing that in any significant quantities, wake up me.

We do not always need electricity as an output. Even then, you can combine SOFCs with gas turbines and still get an electrical output. Efficiency is still very high. The equipment is mostly made out of steel or other cheap materials. You re

The alternative is SAF, which has to be a synthetic fuel if the goal is to be honestly green. However, that requires enormous green hydrogen production anyways.

Biofuels are not green. It is purely greenwashing since the production of biofuels is very carbon intensive. It is also very environmentally destructive since it takes a lot of farmland to produce.

It will make sense for nearly all transportation that can’t be directly electrified. The problem with batteries is that it is a massive resource hog, and one that is fundamentally unsustainable. It will have be abandoned. The only alternati

Hydrogen planes have been tested. The physics works out provided you have more room for the tanks.

It’s the theoretically best one possible. BEV fanatics are just spreading propaganda against it.

This story is Tesla propaganda by a Tesla propagandist. The author of the piece wants every EV maker other than Tesla to go fail. Look at the history of articles the person wrote. No surprise, it’s another attack on an alternative green tec

This is one area where we’re guaranteed to see a fuel being used. Either synfuels, e-fuels, ammonia, hydrogen, etc., it will have to be something that can be carried into the port from elsewhere. There’s no other way around this problem.

It would have to be on the order of 1,000-10,000x cheaper for it be worth it. Not to mention that each wafer needs dozens of layers to function. So you will need to wait a very long time for all the layers to be completed.

Electrons are electrically charged, so a beam of electrons will interfere with itself. The only way around this is to have a very narrow beam, but that kills throughput.

The final challenge will be cost: With every iteration, costs increase dramatically. At some point, it simply ceases to make sense to scale down transistors any further.

DOE has no “track record.” It just funds things based on government policy. Again, no evidence that this recycling is happening at scale. And given the enormous complexity of the problem, something no one has even bothered analyzing, it see

In the long-run, likely FCEVs. They are also EVs, just without the huge batteries. Advances in production are likely to reduce cost to ICE car levels. Advances in hydrogen production will make green hydrogen follow the curve of wind and sol

In the short-run, just more practical cars such as hybrids and plug-in cars. In the long-run, it is the inevitable plunge in cost of hydrogen, which will make fuel cell cars the cheaper type of car to own.

We never should have abandoned nuclear thermal rockets. Anti-nuclear fearmongering set us back by decades.

That is only true right now. There will be opposition to those ideas in the future, not to mention fundamental limitations of those ideas. There will be a return to nuclear power simply because it is a good idea and the anti-nuclear worldvi

That's pure delusion. People will reject your solution just like they reject nuclear. Even more so, since millions of people can't afford them.

You can replace the centralized navigation system in a federated system if it becomes necessary. But that is not possible in a centralized social media system. Everything is permanently centralized in that system.

Centralized social media is the reason why we're in the mess we're in right now. Eventually, someone will come up with an effective way to navigate decentralized social media. It will likely mirror what Google did for Web 1.0.
