Electric cars and planes are going to be huge, of course. Increasingly batteries will be replaced by fuel cells, and the hydrogen that powers them will be produced by means of hydrolysis produced by sunlight. https://phys.org/news/2021-04-hydrogen-fuel-machine-ultimate-self-improvement.html https://phys.org/news/2021-04-hydrogen-fuel-machine-ultimate... https://newatlas.com/energy/osu-turro-solar-spectrum-hydrogen-catalyst/ https://newatlas.com/energy/osu-turro-solar-spectrum-hydroge... https://uh.edu/news-events/stories/2017/April/05152017Ren-Water-Catalyst.php https://uh.edu/news-events/stories/2017/April/05152017Ren-Wa...

  For electric planes, it is. Up until a year or two ago, I still had fairly intelligent people still saying electric flight is “essentially impossible.”

    AFAICT intelligent people are still saying that apart from short-hop 10 seater planes, electric flight is impossible.

      Yeah, that’s what they say if you press them on it today. They’ll keep moving the goalposts as soon as it becomes too obviously wrong, and then never admit to having been wrong in the first place. ;)

        Could you show me anyone making substantiated claims that 100-ish-passenger, 1-2 hour flight is doable with battery electric?

    Fair enough. Musk was on Joe Rogan talking about it last month so a lot of people have heard of it.

The goalposts are actually moving in the other direction. Batteries keep eating fuel cell's target applications. And there is currently a very large PR effort by fossil fuel companies to promote hydrogen. I'd suggest extreme skepticism about any "news" promoting it at present. Always ask where the hydrogen is actually coming from in the present, not 30 years down the road.
