Oh fuck im already seeing the results of the first bad batch of Samsung Galaxy Note 17s.

Forget suitcase nukes, cheap chinese mobile phones will be the next genuine terror threat.

I know you're just joking but some people have seriously speculated that battery fires could be the result of poorly understood nuclear reactions: https://www.slideshare.net/lewisglarsen/cfakepathlattice-energy-llc-len-rs-in-liion-battery-firesjuly-16-2010

We're talking "High Power Density Compared to Existing Nuclear Batteries". We're talking like 1V@1A. This essentially also has a half-life of 12 or so years. Meaning @ 12 years, it'll be 1V@0.5A, then another 12 years is 1V@0.25A, etc.

They are also beta radiation. Tritium radiation itself doesn't penetrate more than a couple micrometers of skin, and in a lot of cases, the glass that they are encased in are lined with a phosphor which absorbs the beta radiation and then re-radiates light. This light is captured, typically, with a photovoltaic cell of some sort (or a betavoltaic cell if you can get ahold of one)

Russia has a long and well established history with nuclear batteries.

Here's a video of a guy DIY'ing a nuclear battery. In it, he explains some of the history and why they are used. https://hooktube.com/watch?v=KKdzhPiOqqg

This guy has a great chemistry channel. As someone lacking a chemistry background even I enjoy his channel (which is almost entirely chemistry) and commitment to science and the discovery and invention process.

Very cool stuff, but they didn't mention any health-related effects from nuclear batteries. They mention that it can be used in a pacemaker, but I wonder about more serious health issues if you put radioactive material in your chest.

It's a beta (high energy electron) source. A thin layer of foil (or the first few micrometers of tissue) is going to stop it. Betavoltaic cells for pacemakers are not a new thing. They have a very good track record for implanted electronics.

It also might be a viable back-up power source for the chip-scale spacecraft that the breakthrough starshot initiative is trying to design for getting to proxima centauri in a reasonable time.

@superkuh is correct and this my post with video link, IIRC, speaks some to it. https://voat.co/v/science/2587166/13002251
