>>12895>Could be exciting.kek physics pun, you know because ionized electrons (beta-radiation) are sometimes called excited electrons.
>Inb4 dystopian horror predictionsYup it already started.
>>12899>tons of sporadically thrown out nuclear batteries.Assuming this takes off, and they're really good at optimizing mass production. I would expect that a 1 Watt nuke-powercell for consumer items will cost at least 50-100 bucks. And it'll be something that comes in a standardized size, that people slot into their electronic devices (which will not ship with it). And people will consider it a precious item that'll last them for many devices, like a nice quality charging-brick. There will be no problem to recycle these either. It's made of valuable materials. Also the betavolt battery in OP, uses a radioactive nickel-63 isotope that decays into a stable(not radioactive) isotope of copper. So even if people throw them out, it'll just be a waste of copper.
