Where I work the bio gas division costs almost nothing to operate and saves around $1,000 worth of gas per day.
That sounds pretty efficient to me.
Due to the high cost of natural gas setup I just waited and went electric.
But I wouldn't mind a large selection of junk yard CNG left overs, that way I could use CNG instead of propane for back up home heating.
