  • This is a very good point. If it’s as easy to replace as AA and it lasts longer, it’s just better all around.

    A few problems: it will still use rare earth metals, and those are a hot political topic right now with China restricting them

    The fact that AAs are eternal. Who knows if this specific battery will still be available in 10 years.

    Also, the small problem of you can’t just buy a new one at Walmart. It is small, but out of sight, out of mind, and out of the public consciousness.

    Problems with Li-ion itself, I suppose. What we really need is a standardized small rectangle form factor since Li-ion is just more efficient in that shape.

    What? Light doesn’t have speed, speed would imply some sort of relative movement that would require something like 3 spatial dimensions but even then everything would move at the same “speed” if you add up the dimensions the real question is why are you moving through space? And that gets into causality and a bunch of other God stuff you wouldn’t be interested in.
