I apologize if this isn’t posted where it should be, this is my first post. I just thought I’d show off my make-shift CO2 generator using dry ice. You can buy dry ice for about $1.50/lb at walmart and I thought it might be a decent source of CO2.
I’m open to comments and questions because I don’t remember seeing someone else try this so I figure it’s either an uncommon good idea or otherwise maybe it’s a bad idea and that’s why people don’t do this.
How it works: The main chamber holding the dry ice is a vacuum insulated growler with a line running to an water airlock and another line running to a deeper water reservoir for the purpose of pressure regulation. I can control the flow of air going through the airlock and any excess pressure gets blown through the deep reservoir.
Like I said this is my first post so please be kind.
TLDR: Made a co2 generator with an insulated growler and two water bottles of varying heights for flow/pressure regulation. Please tell me what you think.
