New battery approaches gasoline energy density

[gridlore]

You can't buy a lithium-air battery (yet). You've probably never even heard of one. They were only invented 15 years ago, and for now, they're still just laboratory curiosities.

But with the latest lab breakthrough, the lithium-air battery (also known as the lithium-oxygen battery) is nosing up into the energy density region seen in gasoline. If you're thinking battery-powered car, maybe your sights are too low. How does battery-powered airplane sound?

I'd like to see a battery powered rocket, please.

I actually did this using Traveller Fire Fusion & Steel. Battery powered orbit to ground lander.
