Despite its tiny size, the battery manages to achieve a 200-watt-hour-per-liter energy density, which is comparable to that of larger, conventional lithium-ion batteries.

    This is kinda like saying that a radio thermal generator could power next gen’s phones.

    I am sure it could, that doesn’t mean that it will.

      Sure, if your phone only needs a fraction of a watt and you’re okay with an unshielded neutron source pressed against your head.

        If the mars rovers can function on a fraction of a watt, then I don’t know why my phone can’t…

          If the mars rovers can function on a fraction of a watt,

          It doesn’t?

          Perseverance’s power system works essentially like a nuclear battery. …The power system will reliably produce about 110 watts …The MMRTG also charges two lithium-ion batteries, … Perseverance’s power demand can reach 900 watts during science activities.

            Yeah, see!

            An RTG could power my phone!

            Sigh, let me spell my point out for you…

            What I mean is that I can absolutely believe that a solid state battery could power the next gen smart watch, I doubt it will.

            Just as an RTG could power my phone, but I doubt that it will be powered by it.

            To give some perspective on this, I’ve lived for the last three months in a camper with a DC fridge. 1350 watt battery. The rtg at 110w/hr would keep my battery charged. 50 watt tv, 72 watt fridge, 24 watt starlink plus lights and waterpump. It would be just enough for me to live on I’d say.
