This is my hometown of Blackpool UK and this old photo is from the old gas works and we was always told that natural gas is from old decaying plants and animals from prehistoric times similar to oil so a kind of fossil fuel but yet again is complete nonsense because look at the photo here you can see the well used mineral bays of where they used a tractor with bucket to load the minerals for extracting hydrogen from the huge cylinders which moved up and down to produce and harness the hydrogen gas its that simple of a deception
