Thats why piston curve stops at 1970, as it seems piston engines haven't improved since.

Well, you quote energy per seat and I quoted energy per load if I recall.

Again, roger that as above. Gave it the ol' college try. As you say earlier anyway, not likely any one's going to actually
do work on any alternatives soon, and as I say, people think satisfying their immediate desires are some kind of right because they can afford it and everbody else and the world be damned. People suck & then ya croak.
