#22I'd rather have to charge the smartphone battery everyday, than carrying radioactive material in my pocket.
You don't like bananas in your pocket? :D

#25Hmm. Even if it emits only alpha radiation which is super easily shielded, wouldn't it cause some other emissions through bremsstrahlung? Not sure if I'd be happy with this. But for implants I see the benefit of course. Never having to replace anything
It depends on the kintic energy of particles. If it's low enough I think the frequency of photons generated might be low enough to be safe.

#26first time I heard of nuclear being used this way. Undeniably interesting, though obvious safety concerns!
Yeah cool tech, but if it's in a device that pulls a Samsung Note, you become an unwitting dirty bomb.
It seems like the kind of tech for industrial application anyway, one of them things that's just impractical for the consumer world.

#27This sounds too good to be true!
The catch seems to be delivering only 100 microwatts. Very far from powering a phone.
I think it's for sensors. With some capacitor and a smart sensor that powers on only after voltage exceeds some threshold and does the measurements and sends out the result in one short burst before energy runs out.

Except Samsung Notes combusted because lithium-iom batteries can combust.
A phone powered this way wouldn't have any combustible spontaneously ignitable materials in it.

#30100 µW = 0.0001 W * (365×24) = 0.876 Wh per year. Which is about capacity of CR2032 cell.
Regular good 18650 battery have capacity of ~12 Wh, so assuming no loss at all, single battery will last for 13 years. In real world, self-discharge will drain battery faster than that.
