That shows to me that there is a fundamental theoretical limit being

Are there any other chemistries that have potential? If not, we are ****ed.

Lithium air, which uses raw lithium and oxygen, could be theoretically
good enough

But no one has made it work yet outside a lab.



And it's no good saying "We can develop or discover them", no we can't. Either
possible chemistries are known about today, or they do not exist.

Remember that when the Wright brothers did their thing in 1904, the only think
that stood between them and the 747 was engineering development.

Yup. Once we have hydrocarbon fuel energy densities, flight was just a
matter of engines and structures
