Thanks for posting. The irony is that after we transition to a domestic and community solar hydrogen ecology, things like F1, as well as all aerospace, could do as much as it likes, even bringing back things like concorde. The effect will be the opposite of what we see now with everything powered by extracted energy. The process of undoing everything nature created originally using the energy of the sun, creating all things other than heat, back to heat, by us, is what is heating the planet. But if we created the fuel in the first place, that creation is us doing the same as nature, it has to cool the planet rather than heating it, because we will be converting energy that would otherwise become heat, if neither we nor nature used it (Notice we destroyed a large portion of nature)

The result of using the fuel, is to convert at least part of it to kinetic energy, which again is not heat. So even in the worst case, our net activity would be to cool the planet, rather than heating it.

All internal combustion engines are convertible to run on hydrogen, this is a job for fuel systems Engineers.

Personally I would love to be driving something considered obscene in the old world, like an old V16 Bugatti, converted to run on hydrogen. That would be pretty cool I think.
