I have known this guy since 1968. He is 2 months away from 80 years old. Has a BS in biology and chemistry. MS in Biology.
After college he went back to the hills of Kentucky and proceeded to drill his own oil wells creating a small private oil enterprise. He has become a self made millionaire. He heats his home with NG from one of his wells. Most innovative human being I have ever met.
I saw this old double flywheel engine in his barn 45 years ago. Went to see him yesterday. He used a come along to drag it out of the barn. Had to braze teeth on one of the internal gears. Hooked his it to a natural gas tank and got it running. Why? Just because he enjoys repairing things.
