There are also non-hydrualic forms of fracturing. Back in the 1960s, the Atomic Energy Commission partnered with utilities to explore the feasibility of releasing natural gas with underground nuclear detonations. As crazy as this sounds, it actually worked quite well. The problem, of course, is that it created an enormous amount of underground radioactive debris and the natural gas that was extracted was itself radioactive. http://en.wikipedia.org/wiki/Rulison http://en.wikipedia.org/wiki/Rulison http://en.wikipedia.org/wiki/Project_Rio_Blanco http://en.wikipedia.org/wiki/Project_Rio_Blanco http://en.wikipedia.org/wiki/Project_Gasbuggy http://en.wikipedia.org/wiki/Project_Gasbuggy
