Here in Canada, it’s half the cost for rice. I don’t imagine it’s that different in the US (at least, pre-tariffs). Assuming 2500Calories per day, I can get a year’s worth of Calories from rice for about 500CAD while it would cost me 1k CAD for the same on soda (calculated based on $1/2L of Crush cream soda).
I think at this point, it would be more economical to distill the water than to burn up contaminants.
