We first need solid state batteries. And not just companies advertising them or outright selling scams.
There are already companies manufacturing solid state batteries, it’s not like this is a theory, it’s still in its early stages but these are real
Now that Samsung is doing it, you can expect the production to ramp up significantly. Hopefully this is going to be like time when Sony started manufacturing LIBs at large scale and changed to world.
I remember hearing about them when they first started late research stages(like figuring out how to scale to mass manufacturing levels.)
Was it…uhhhhh…snaps fingers what’s his name, Dr Goodenough? The guy that was a major player in all our modern battery tech?Yep, that’s him
Nice! Took me the better part of 5mins to dredge his name from the deepest folds of my memory, glad I got it right.
Not only that, there are products you can buy right now with solid state batteries. The first power brick with a solid state battery is actually available for purchase.
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.
Uh yeah that definitely needed to be “spelled out” from your prior comment.
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.
