have the potential to deliver the desired power thanks to a high energy density - a measure of energy stored for a given weight - that could be 10 times that of lithium-ion batteries and approach that of gasoline.
The fact that we've confirmed that this is even possible is incredible. And don't forget, in terms of existing IC engines, gasoline is only about 30% efficient at converting its stored energy into movement. We've built a few that can do 38%, but thats not even in commercially available stuff, just test bench machines. If we can get even to that, we're doing something amazing. If we're approaching the actual energy density of gasoline, not the power to the ground number, that is practically a holy grail of science.
Who gives a shit if its 20, 40, or even 100 years down the road before this battery tech is in every device, the fact that we know its even POSSIBLE is incredibly amazing, incredibly worthwhile to report, and damn exciting, just knowing we're on the right track.
Adapt. Enjoy. Survive.
