It's tough to beat the btu in a gallon of gas.

With propane the simplist, cheapest mixing valve will work as well as
the best fuel injection. Stuff is 100 octane, as well.
The stuff _is_ available many places. Slightly more BTU per pound
due to the slightly higher proportion of hydrogen. I had propane heat
at my previous address, and adding a fitting or two and a hose to the
1 000 gallon tank would have been easy. If I had had a 100 octane hot
rod I would have done it. Gas does have higher energy density but that
may not necessarily matter. It does with planes, more so than cars and
boats.
