7 1/2 hp might seem very small, but all units are not used al the time. The load is staggered between alternator and air compressor. The air compressor has an output of 3.5 cu. ft. per minute. It only runs about 20% of the time, leaving just the alternator for the engine to power the remaining 80%. The waste heat generated by this rig is ""free"", so to speak, since it represents no load on the engine. (The air compresor is an old York refrigeration compressor.)

Ray Martin’s Homestead and Methane Gas Generator

The simple life at the Junction starts with the house, originally the shell of a small fishing cottage. As Ray put it: “No plumbing, no electricity, no floors . . . just a hull. But the price was right.”

“We had to have the place livable by the opening of school, just six weeks off, and everyone pitched in to help. Eight-year-old Billy worked as hard as anybody. A job in the city kept me busy 12 hours a day, so we tackled the house late at night and on weekends. The materials were salvaged from various buildings that were being torn down here. in Houston, and we got all of them simply by asking very nicely. Most demolition companies are glad to have you remove the leftovers they can’t sell readily.”

“We finished the bedrooms first, and went on to nail cabinets, install scrounged bathroom fixtures, make a plywood kitchen counter, and put in a sink. We’d never realized just how much work was involved in fixing up a house!”

“Then the real fun began. We checked around and found that the cost of a water well would be about $1,200. There was no way we could afford that — and school time was getting nearer — so we decided to do the work ourselves.”
