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?
Some microprocessors in deep sleep mode can consume less than 100 microwatts, so I guess it could be possible with this version, but you’d need to charge for a long time. The power consumption of an active ESP32 can reach 700,000 microwatts.

I think for embedded iot type apps it could be great, pair it with some caps for peak loads (read/transmit).

I have some environment monitoring units that run on cr32 that last around 12 months (not ESP’s ;) )
