    Battery tech is, IMHO, one of the biggest things holding human advancement back. Any improvement in this should be lauded.

        Nikola Tesla already invented it. Inductive charging was originally meant to be exactly that. (And part of an impenetrable defense field that would fry anything conductive flying overhead,)

        The problem is that it’s horribly inefficient, and generally would then demand that your car and phone and anything with circuits (or indeed just a loop of metal…) be designed to accept the frequency and power of the one system- Or to be shielded from it.

        Either way your phone is getting bulkier and your car probably gonna charge slower

    Uh huh sure. How many countless articles are written a year with the exact same title “xyz incredible battery tech will revolutionize the world!” And you never ever hear from whatever the xyz was ever again. Been going on for decades, will probably be writing the same exact post from my lion powered device in another decade.

      It often takes decades before a revolutionary technology is first discovered/invented, to when it js implemented. Not only does the end product need to work, but its constraints need to be practical, it needs a process that is economical, and it then needs to be scaled up, and the issues caused scale need to be ironed out.

      As such, once the technology is actually implemented, it seems like a much more incremental change than the leap forward that it was a decade ago.

      They do just creep in though. my phone now has a battery 4x the size of the one in my phone 5 years ago (although the processing power of the phone means I get half the lifetime). However it charges in 90min not 8hrs and supposedly lasts thousands of recycles without loss, where as my old phone needed a new battery after 6 months
