These batteries provide milliwatt level power. Enough to power, maybe a clock circuit without display.

- bravesoul2 1y agoProbably good for the dark, remote, lots of space applications. E.g. a radio beacon near the poles.
- blueflow 1y agoMaximum wattage of the battery would also be maximum wattage of the radio signal.
- ColonelPhantom 1y agoWouldn't it be feasible to add a tiny battery or capacitor? Assuming the radio doesn't need to transmit continuously it can be powered via those which are then powered by the "forever battery".
- bravesoul2 1y agoYeah you'd need a lot of them. Instead if a AA battery maybe you need a truck's worth of this. But if it means you dont need to go back for a while...
- gpderetta 1y agoRTGs (radioisotope thermoelectric generator) are already in use for both deeps space and remote applications. Not sure how this differ. Maybe better efficiency? Still, why is it called a battery instead of a generator? Oh, maybe size as RTGs are bulky. edit: there have been very small RTGs for use in pacemakers. The difference is really that these are not thermal but use the beta flux directly.
- wongarsu 1y agoThe Soviet Union also had mass-produced RTGs for powering equipment in remote locations on earth, like light houses https://en.m.wikipedia.org/wiki/Beta-M https://en.m.wikipedia.org/wiki/Beta-M
- gpderetta 1y agoOh, RTG pacemakers were already betavoltaic [1]. So this is really an incremental improvement on existing tech. [1] https://en.wikipedia.org/wiki/Betavoltaic_device https://en.wikipedia.org/wiki/Betavoltaic_device.

- supertrope 1y agoMy water company installed a smart meter. Inside is a 30 year battery. When the battery is depleted it should be time to replace the whole meter.
