Technology

It's a betavoltaic, it's an established technology but not yet commercialized. There was a scam/grift nuclear battery startup that used a similar system except they were making wildly extravagant claims, going as far as to literally lie about the output right next to the example picture which showcased the actual power output printed on the side of the device. It's a really cool concept but of course they had to fuck it up by being blatant charlatans. Oh well, at least China is here once again to pick up the slack from America's failings.
