The WSJ has an informative article describing the innovation of the way American businessmen discovered a way to get gas out of the ground–fracking. This is no less an interesting topic for no other reason than we are seeing gas drilling and wells all over this part of West Virginia.  Is the gas/shale discovery a good development?  One can say yes given nuclear’s uncertain future post Japan earthquake.  Despite some environmental concerns, shale gas will likely account for 50% of our gas supplies in the next couple of decades.
