News Scientists develop the world’s first carbon-14 diamond battery, offering a 5,000-year lifespan — the device uses radioactive decay to generate low...

This sounds like cold fusion. Watched the whole thing and no one said how many watts they've achieved so far, and they are already talking about up-scaling and manufacturing.
 
One microwatt per battery - it's hard to imagine a huge number of applications for it. The carbon is sourced from used nuclear reactor graphite blocks. The diamond coating stops radiation escaping from the graphite but you definitely don't want to break one open.
One article I read says they ONLY cost around USD20 per NANOwatt so only $20,000 for a microwatt or 20 million for a milliwatt! A bargain if you are a billionaire.
 
This sounds like interesting tech with very little application. This feels much more like the start of areas that could be useful with different C14 combinations with other materials to catch/interact better. Interesting but that power output to size is so low I don't see much in the way of use as a primary power source. I do wonder if it could be used in conjunction with other things as sort of a backup battery or unlimited clock battery or something though. Just those real low level things you don't want to lose power on as it could cause issues after a reboot of tech in deep space or on a remote camera or something.
 
Interesting. Diamond is also carbon. Coal is also carbon.Carbon-14 is producing energy very slowly like a burning coal. We are made and created from simple elements like carbon, nitrogen, and oxygen and hydrogen. What a wonderful universe
