If you generate the electricity from the planet, you destroy it, by Landauer's principle, pushing up the temperature, whilst if you generate the electricity from the energy of the the sun, you do the opposite, pushing temperature down, again by Landauer's principle.

Notice it is not physically possible to pass economic product created by the energy of the sun to anyone at profit.

To pass it to people, so as to remove their need to keep extracting, it has to be passed for free. I show a diagram explaining why that is, inarguably in my story "Forget Greenhoouse Gases", as well as in some others of the 500 plus now in Medium.

So how long do you think we can keep destroying the planet, and how long do you think any energy value at all will remain in money issued as debt, when creation of all economic product has moved to solar?

As for aerospace flying on lithium vs hydrogen, its a no brainer, and I am telling you this as someone with a lot of experience in things that fly.
