  • In the UK, large stocks of civil nuclear waste contain significant quantities of americium-241. That makes the fuel not only long-lasting but also readily accessible. Instead of building new reactors to produce plutonium, agencies can extract Americium from existing waste, a form of recycling at a planetary scale.

    Using it seems way more preferable to just letting it sit in casks.

    Traditional RTGs utilize thermoelectrics, which are reliable but inefficient, often achieving only five percent efficiency. Stirling engines can convert heat to electricity with an efficiency of 25 percent or more. […] Stirling engines introduce moving parts, which also raises reliability concerns in space. However, Americium’s steady heat output enables RTG designs with multiple Stirling converters operating in tandem. If one fails, the others compensate, preserving power output.

    That seems a little ridiculous though. All that friction requires a lube that’ll last “generations.” In space, without gravity, and at incredibly low temperatures.


  • There is a reason nearly every software corporation out there is allergic to GPL code, and similarly why they love MIT/BSD/Apache code. I urge you to consider why that is.

    I’m well aware. Are you assuming that people using permissive licenses are somehow incapable of understanding the implication of their license choice?

    Licenses do affect how software is used, that is literally the purpose of them.

    You implied that I would be “contributing to something” I would object to. I’m left to fill in the gaps. Maybe be more direct in your comments.



  • I’m going to continue releasing my software with a license that I deem appropriate.

    For things I’m building only for myself or that I have no interest in building a community around, I couldn’t give a shit what people do with it or if they contribute back. My efforts have nothing to do with them. I’m releasing it for the remote chance someone finds it useful, either commercially or personally. Partially because I’ve benefited from others doing the same thing.

    I’m not anti-copyleft, but the only time I actually care to use something like the GPL is for projects that would be obviously beneficial to have community contributions. Things that require more effort than I can put in, or that needs diverse points of views.

    I use permissive licenses not because I’m a pushover, but because I really don’t care what you do with it.
