I wonder where you get your information from. More likely, the thread would be deleted- that's a warning to shut up. People persisting in posting things the government doesn't want posted get a temporary ban. This is bad because WeChat is also used as a payment vehicle on their phones. Further...

You selectively read my post. The USA seems to be heading in the same direction as China, although we are not there yet- I hope we never get there. I posted references other than FISA. I'm not convinced it is a better process now. Do we really have an independent judiciary? We might, but they...

No, the USA seems to be heading in the same direction- Primary not certified because one party doesn't like the outcome, makes false narrative about voting machines...

What I see is that the USA is heading in the same direction as the Chinese government, but using a different method to "keep their hands clean". The US government buys location information: https://www.vox.com/recode/22278402/x-mode-sdk-google-play-ban-location-data Overly broad "keyword"...

And Amazon, Google, and Microsoft don't cooperate with the US government when asked? Apple is, AFAIK, the only one that didn't bend over when asked to unlock an iPhone. The police need merely ask for your phone records here, after getting a court order, which doesn't seem very difficult. Many...

The lightbulb was a miniscule result?:rolleyes: In the mid to late 1800's, there were many people working on an electric filament light. A workable electric light was made during the Napoleonic wars- it is still used today. It is called the arc lamp. If you were around back then, you would...

I’m sorry that your post doesn’t make sense. Edison succeeded in making a practical lightbulb and an initial infrastructure to support them. How long he took is immaterial.

Why does it matter?

Aside from your selective reading, That's how we make progress :) I'm not one to tell someone something is impossible when they seem to be making progress. Maybe it won't work. But the people doing it have more real data than either of us.

Did you read the earlier posts in this thread? My opinion about hydrogen? I know you didn't. Try reading them. I'm skeptical, but if someone is actually flying a plane partially on hydrogen, I'm pretty sure they are collecting data about how to refuel it, how much hydrogen they can store, and...

Yet someone is managing to get it done :rolleyes: ...see below

Yes, interesting times! I hope they meet their goals, although H2 powered planes have been around for some years, with the majority of the useful space being pressurized tanks. This one is a fairly sizable UAV: https://en.wikipedia.org/wiki/Boeing_Phantom_Eye It's entirely possible that the...

It depends on the company. Some are independent, others are ties to the Chinese government. Your simile doesn't hold here.

Well, whatever batteries were in use at the time Peter wrote the article. I'm pretty sure the "big brains" working on this are chemists and physicists who know what they are doing;)

Here's a perfect example of what I said- now that the government got embarrassed, they will do the appropriate inspections now: https://en.wikipedia.org/wiki/2023_Yinchuan_gas_explosion

You, and they, are making a basic error. Hydrogen is really a storage medium for the energy harvested through other means, solar, wind, nuclear, hydro, etc. You generate electricity which is used to hydrolyze water and produce hydrogen. This hydrogen could be used in fixed-location fuel cells to...

I hope I'm wrong, but I think those people are a bit optimistic. Here's a summary of the problem: https://www.energy.gov/eere/fuelcells/hydrogen-storage#:~:text=On%20a%20volume%20basis%2C%20however,based%20on%20lower%20heating%20values.

I don't see what point you are attempting to make. You can buy electric cars now than can go 400-600 miles on a single charge now; the original Tesla went ~250 miles on a charge. They are testing a cars now with 700-800 mile range. Battery technology is improving, no matter who makes them!

I really don’t think hydrogen is the answer, even using fuel calls, unless you make it more energy dense. Like attaching the hydrogen to a carbon atom! Methanol fuel cells will give you decent range. When you add passengers and other cargo, there isn’t a lot of space for a hydrogen tank.

I think SAFE will be the answer for passenger planes. Hydrogen isn't very energy dense. People who remember Henning will also remember he was fixated on the stuff. The ICE beat hydrogen for range, even if it was liquid hydrogen. If they improve the energy density (adsorbing it onto something or...
