I know they are dragging heavy machines all over parts of the US, currently.My uncle's farm is sitting on top of a natural gas pocket and the oil company said, that the pocket spans most of north east Ohio, down about 4000 feet and could possibly fuel us for next 100 years. They also think it will be fueling our vehicles? I suppose a 4 stroke could be converted from a gas tank to a compressed tank/special carb or gas injected system? The future could get quite interesting?
I don't think you get near as much mileage / power per volume so packaging might be an issue on a bike. note the tank size on the one Paul Sr did...
It has to be stored under very high pressure to have any mass so that what ever vehicle is running off of it has some range, kind of like propane but higher pressure and a lot less range. It's ideal for stationary engines and heaters and the like. When I lived in Oklahoma many of my friends had it hissing out of the ground in their pastures and sometimes bubbling in their creeks, it was just going to waste because there was no pipeline nearby to haul it away.
