Gaseous Gold

Description

The fuel of the future's not coal, or oil, it's gas, baby! Those marshy ponds to the southwest spew it out by the ton, and I've got just the invention to put it to use--a new type of engine that runs on the stuff. The gas is a real pain to collect, though.

If you feel like making a humble contribution to the future of science and industry, why don't you help me get some of that gas? You can see it coming up from vents near the water.
