In theory Stahlman's Gas, named in honour of Professor Stahlman, is a source of energy to be found more than 20 miles below the surface of the Earth. It is believed to be infinitely more powerful than North Sea gas.
Professor Stahlman described the gas as "a vast new storehouse of energy that has lain dormant since the beggining of time." He founded the Inferno Project in an effort to drill beneath the Earth's crust in order to tap the gas. Due to insurmountable problems with the project, most noticeably the unintened tapping of Stahlman's Ooze and the subsequent transformations of humans into Primords, the project was abandoned and the existence of the gas remains unproven.
