I am wondering, if we had Ln2 at the space, how would makers use it in their projects?
Also wondering, are there makers interested in building a generator?
Science has a dewar, but no source of LN2. It would be handy for all kinds of things, but especially cryogenic storage of live strains. More practical than obtaining and maintaining a -80 freezer.
One of many links about Ben Krasnows sensational DIY project.
He is a maker hero.
