The world needs a new source of energy, an unspillable source.

Gulf of Mexico oil spill-blow out preventer

Industrial3d creates video for CNN with a video showing a typical blowout preventer working properly and showing it not working properly, for example if the pipe rams were not close the pipe might be bent or not centered and therefore could cause the shear rams not to work. or if the pipe joint was in the area of the shear rams, the shear rams would not be able to cut through the pipe joint. or if the wall thickness was to big on the drill-pipe.
