Someone asked for the relative energies of natural gas
compared to
    Gasoline. What I've been able to gather is :
    1 cu/ft NG=1028 BTU
    1 gal Gasoline=125000 BTU

     Here's what I find in my propane book;
LNG contains 23,891 BTU's/lb, at 2.5 lb/gal.
Propane contains 21,670 BTU's/lb at 4.23 lb/gal.
