This is NO exaggeration. You can build a lot of things in a garage, or a million dollar factory. Chips can't be built in a BILLION dollar factory.

No country has 100% uptime. Like hospitals, you have batteries and generators onsite capable of picking up the load without interruption.

If they've done this, this will almost surely be enough to get them to the forefront.

It's a monumental distinction. Petroleum is energy that was created 66-250 million years ago. 100% of commercial hydrogen was created in your lifetime, but about as likely within the last year.

If you generate electricity and transmit it for use in a car battery, you end up with at least 70-80% of it going to the wheel. With hydrogen, that same electricity results in only 25-30% making it to the wheel.

The only thing that makes that 25-30% improve is by scrapping electrolysis (the only green hydrogen available) in favor of reformed natural gas, which is just fossil fuel with extra steps and less efficiency.

So the alternative to battery electric powertrains is building 3x as many power plants to use hydrogen, or using more fossil fuel. Neither of those are the solution we're looking for.

It's less of a "source" of fuel and more of a storage method. If you're using electrolysis to make it, you're taking electrical energy and using it to convert water into a store of energy. That has inefficiencies at each step (generation, transportation, storage, and finally in its use.)

That was a joke in response to the a whiner throwing out the lamest conspiracy theory ever. There was no coup and Elon certainly didn't have the wealth or influence to orchestrate one back then.
