Hah. Neeeerd.

It's the gist, yes. My problem is that if the idea is to scale the process to something that's more than a 100ml jar on a bench, this experiment is almost a spherical cow in a vacuum. For starters, you have to take steps to keep it under 80C, so it'll either need to be current-limited (takes more time) or be actively cooled (takes more energy, likely skews carbon balance). As it is, they probably just put a moist paper towel on the vessel and call it a day. Your product and reagents are strongly alkaline, so not all materials will stand the reaction conditions for whatever amounts of time. Those aren't insurmountable problems, sure, but stack enough of them and this might not be as viable as it looks on paper.

That said, if there's a will there's a way. I'd like it to be me making mountains out of anthills.
