Even the creator of the open source initiative has said that open source has failed and we need more restrictive licensing because open source simply is too permissive and has been aggressively exploited at the expense of the people, who it was meant to empower.
For me, source available licenses that are open source except specifically restricting for profit hungry, exploitative companies and corpos are with something like non-commercial clauses are fine for an end product. I use CERN OHL S v2, but I can't fault people for going noncommercial like the entirety of the art and 3D printing world pretty much already are to protect themselves.
This is theoretically something sodium batteries would be good at right?
Aren't they not as sensitive to storage voltages? They are almost a perfect lead-acid replacement. Plus a UPS is a great usecase because it doesn't matter if it is 33% bigger to achieve the same capacity.
