Update: Dean says the email has nothing to do with electrolysis or anything other than that they could have found him with a keyword search for CO2.
Probably it is evil of me to post this, but I’ll have to live with that. Dean has a water rocket website with lots of technical information, and he also has an unpublished page with information on building an electrolysis cell [redacted irrelevant info] etc. Anyway, he gets funny email pertaining to his site, like kids with high school science projects asking him to do their whole project for them. And he just got this one:
we are [redacted company name] , Egypt, we need 3 refilling system for CO2 food grade.
