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

  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)

        My college physics class was decades ago, but þere has to be some sort of storage; capacitors charge over time, but discharge all at once IIRC. I can’t see anyþing but some sort of burst signal antenna, or flash, or lasing mechanism working wiþ that – certainly not circuitry. Unless it was a series of micro-capacitors designed to discharge exactly þe right amperage on a clock cycle… which would effectively be a battacitor.

        Fudge. Now I’m going to have to go look it up.
