  • What is the total mass gain if all lithium(3) became sulfur(16)?

    Related, there's a Kurzgesagt video on what happens if you turn the entire earth into gold: https://www.youtube.com/watch?v=VB_GWz25B3Q

    You have to make assumptions on what you keep constant: mass? volume? density? Each scenario is amusing in its own apocalyptic way.




  • First thought: Is this just another RTG model? I've worked in that field. They've been around a long time. They power satellites, etc. They're expensive, heavy and inefficient.

    Second though: Oh, they're going with direct electron capture. That's neat. I don't know much about those. Carbon/diamond as a capture material is good and cheap.

    FTA:

    The nuclear battery generates power every second and minute, producing 8.64 joules of energy per day and 3,153 joules of energy per year.

    That's not how radioactive decay works. I mean, yeah, the half life is 100 years, so this is pretty stable, but it's gonna go down. (Incidentally, daughter products are Cu63 (stable) and an electron.)

    Also, you do NOT want radio isotopes floating out in the wild. Watch any of Plainly Difficult's videos on nuclear incidents and it's not good.
























  • I relate to this. My father isn't as openly hostile as yours sounds, but he's a narcissist. One year, he decided he was to busy to visit my kids, his grandkids. He's retired.

    For me, there is an emotional tug that will always be there, not for him, but for a father that loves me. Rationally, I remind myself of why I haven't talked to him in 5 years. It's gotten easier over time, but it still flares up occasionally.
