Hence why batteries are not part of the final system solution Enrique. They are cool for small transportation, but will never be cool for big things, and things that need to fly, they have a power to weight mass ratio that no chemistry will ever solve.

This is why you have to look at hydrogen. When hydrogen is finally adopted by aerospace, it will become so much more attractive also for smaller applications like cars.

Hydrogen is absolutely required for aerospace.

The only way we will generate enough of it is to do it on a community level distributed infrastructure.

This is the only way we will get enough solar real estate to gather enough solar energy to create the mass of hydrogen needed to replace all fossil fuels use.

It has to be distributed, because the energy of the sun is distributed. Can't get around that.

Missing this, is you caught up in the details of battery chemistries, it seems to me.
