This sounds too good to be true!
The catch seems to be delivering only 100 microwatts. Very far from powering a phone.

#14Is there any mention of what kind of radioactive decay this is powered from? Based on the name, one might assume beta? This would also track with the "research done in the 20th Century" bit considering beta radiation is just electrons. My point being - what impact does this have on the safety of the device? Any more than certain light sources containing mercury, for example.
Not sure about this particular device, but https://citylabs.net/technology-overview/ apparently makes use of tritium, which is betavoltaic based.
Just noticed for citylabs it says - "Base price starts at $5,250 per battery"
I'm curious what they'd be used for considering the very low power output and cost.

#16to be clear, it's not nuclear as we understand it usually, by having a fission reaction, but using the energy of the decaying radioactive isotopes concerted to electricity. The technology is used in space probes. The issue is that it is still radioactive, and I'm very wary to see an associated pollution if it's used by the general public

Whoever wrote this does not know what an isotope is. Also, the site's attempt to ban copy/paste is annoying.
Interesting product if real!

#18Nothing to see here, delivers 100 µW while your phone needs more than 1000 times more.

#19I'd rather have to charge the smartphone battery everyday, than carrying radioactive material in my pocket.
Lots of things are radioactive. A banana for example.

I first laughed after reading that sentence... I guess they are speaking about some amount of ⁶³Ni, which actually decays to copper as they say.
