3V at 100 microwatts significantly limits its usefulness.
They say they’re planning to make a 1W version, which I assume will be either be much larger or have a much shorter lifespan. How does it work? Does it have a way to stop the reaction or does the 1W battery generate 1W of heat when there’s no load attached?
I think for embedded iot type apps it could be great, pair it with some caps for peak loads (read/transmit).
How long until they make a vibrator that fits these?

I always wondered why there weren’t any nuke batteries available. We have had the technology for decades.
They use a more efficient process. Something about a diamond semiconductor that turns beta particles into electricity instead of relying on heat.
I imagine large part of it is that it’s at odds with capitalist drive to increase consumption.
Can’t imagine why we don’t put nuclear material in consumer products, seems practical.
You mean like Microwaves? Or Smoke detectors? Granite countertops etc. Or watches, and Energy Efficient CFLs?
In smoke detectors and tritium watches the quantity of radioactive material is minuscule compared to the beta emitter in the battery, as in multiple orders of magnitude less. None of the things you mentioned have nuclear material in any significant quantity. If you swallowed or inhaled this battery you’d be exposed to significant amounts of radiation.
A microwave is not an ionizing radiation source.
There is nothing nuclear about microwaves.
Sure, but they are radiation sources and beyond microwaves, “nuclear” material exists in several consumer products, so that isn’t really a reason we haven’t had consumer nuclear batteries.
“Drinking hot tea is safe so drinking boiling water, which is also hot, should also be safe”
The quantity of radioactive material is extremely relevant to this discussion.
