Adding on to what GreyEyedGhost said, since the year 2000 the price of solar power (per watt) has fallen by more than 50x. Because of this huge drop in price the installed solar capacity has been doubling every 3 years. That means that in the time since 2020 we’ve built more solar capacity than we did in the previous 20 years combined.

If that’s not good enough then idk. Imagine holding any other technology to that standard. The model T came out almost 100 years ago for an inflation adjusted price of $27,000 and with an MPG of 7.5. ICE cars today are better in a lot of other ways but they are not 50x cheaper and they are not 50x more fuel efficient than that.

The SSN system is one of the more moronic things the US does, which is really saying something.

Huh ?

What information are you trying to convey by quoting that sentence from the article?

You can buy sodium ion cells online right now. It’s not the next phase, it’s here.

If the tank were made of a carbon fiber composite it would make it a little less scary. CF’s high strength and brittle failure mode mean that the tank would “open up” on a seam when ruptured, but would stay mostly intact. Additionally CF’s low density would mean that any small pieces of shrapnel that were created would have limited penetrating power and range.

Still I’m not sure I would want to stand next to it. At 10,000 PSI a small hole (or opened valve) in such a tank would produce a gas stream with enough energy to seriously injure or kill you (leaks in 4000 PSI steam lines can cut your flesh and create gas pockets inside you). The entire tank letting go all at once would surely create a shockwave that would obliterate you.
