Good point. I think for many a monthly payment is totally enough and maybe even less trouble.

With this workflow though, you can get an extra incentive to do something. Depending on how you implement it, your actions get the extra weight of a planted tree (with each push for example). For me personally, it gives me extra motivation to work on a project and remembers me that I can do something.

Money is not only saved on knowledge creation. Open designs facilitate construction and maintenance for users in developing countries. They can be adapted to local needs and the dependency on manufacturers is reduced.

Nuclear energy is of course a controversial topic.

The main reason for not appearing on the list is that there are practically no open projects in this field.

ITER (International Thermonuclear Experimental Reactor) apparently relies on open source software, but we could not find any open documentation for this project. (https://www.iter.org/newsline/-/3316) The Open100 project is similar. (https://www.open-100.com/) We have found only one big project that is really open and active: Paramek (https://github.com/ukaea/paramak).
