I don't want to kill anyone's entrepreneur spirit, but how much will cng cost to implement and how much would it save? I realize ng is currently about $0.40 per therm (1 million btu).
Correct me if my math is wrong, wouldn't you only need 20 cubic feet at 50psig to be of equal btu content as 10 gal of gas?

50 Psi/ 14.7 Psi (normal atmospheric pressure)=3.47 compression ratio
20 cubic feet x 3.47 = 69.4
69.4/127=0.5
So you have only 0.5 GGE or about 2 Liters......not so much
