CO2 Home Setup

[Zack Vegas]

I’ve long been interested in Peat’s ideas around getting more exposure to CO2, but I never knew how to implement them.  I tried using dry ice in the bathtub, and that did work for a sort of “spa exposure,” but you would need to get new dry ice from a store/vendor every time, and use it within a very narrow time window, as it would “melt” into air pretty quickly, even in the freezer.  There was Soda Stream, but that seemed pretty limited to just making seltzer and maybe a few other carbonated drinks.  Then, I saw this video, suggesting a soda stream alternative-

The link they have for the ready to go setup is a little over $200. It had a much larger CO2 tank, at 5 lb as opposed to 14 oz.  The referenced setup does cost a little more than a soda stream, but does start saving money when you consider refill cartridges.  And I suspected there might be a way to use CO2 in other ways, using that tank setup.

This video gave me the idea-

So, I could use soda bottles and such for “mini” CO2 tanks, that you could then use for other purposes, like bathing a certain area of the body, or possibly for adding into something like an empty milk jug with a hole on the opposite end for rebreathing, described as “Haidut’s tank method” on the old RPF.  Plus, it would be safer to dispense CO2 for use from a much lower pressure soda bottle, rather than directly from a highly pressurized tank.

Overall, this seems like a reasonable and economic setup.  There are lots of places that will either fill or exchange a 5 lb tank, from welding places, fire safety stores, air suppliers, and home brewing operations.  I would just need to make sure that I was getting CO2 that is intended for use as food, or something like USP grade.  A lot of these places would have it, as they supply restaurants and bars and homebrewers for things like soda and beer.
