Comment on Solid-state nuclear battery claims 100-year power for ultra-low energy devices

Seriously though, that should be enough for the sensors and stuff in hard to reach places that the article is about. They could last much longer than the devices that would communicate with them.

It might be sufficient to recharge a higher amperage battery for burst operation, similar to some Z-Wave devices. Now we just need a battery with absurdly high cycle counts and a hundred year lifespan.

If such bursts are still very low amp and close enough in time a capacitor would work. If not, self-discharge would be its main enemy.

Doesn’t a battery still need to be involved? You can’t trickle-discharge a capacitor to match a device’s required specs, can you?
I don’t see much about battacitor technology development.

I don’t know any details, but I know some devices can run on capacitors (for a while)
