Interesting chart, thanks, I hadn't seen that before. Another chart, energy density

Look at where Li-Ion is vs. H2

Wow yeah nothing can touch it in terms of energy density by both weight and volume.

The next step up seems to be ionic thrust. And the next step after that is nuclear. There's so much research going on with ionic rocket engines, it's a very interesting technology.
