>They typically go for $100-$1000/kg... I was doing some searching, but was unable to pin down precise numbers for industrial water rates, but I am seeing something in the single dollars ($3-8) per thousand gallons. Assuming I did not bork my conversions, at $5/1000 gallons, that would be roughly $0.001/kg for water. So, a novel heavy liquid priced at the whole dollars per kg sounds like an enormous capex for a large installation when it could use water instead.
