Sure. I mean it's not 100% that, since the military also re-fuels fighter jets mid-flight before they even reach their target, or they'll send a large aircraft carrier ship into proximity to mitigate for that. So they'll do it, if it's worth the effort. But yeah, battery capacity is a severely limiting factor. And I guess walking (slowly) on the ground also cuts down on military use-cases.

I suppose a lot of people are waiting for better batteries. It'd also help electric cars, bicycles... The whole transition from fossil-fuel energy to renewables... We certainly have quite some demand for good batteries.
