Well given the current crisis once again with OPEC, the price of gasoline and oil, within SPAW is a phenomenally efficient and powerful propulsion system, with no impact on the Ozone layer or lasting environmental effects.

This propulsion system could allow NASA to attain warp speed for missions beyond our galaxy, launch the space shuttle, provide enough thrust for a skateboard owner to travel at 60 mph (zero to 60 in a second and a half), motorcycles, mopeds, automobiles, ships, submarines, etc. and eliminate all reliance on nuclear power.
All we need is a powerful enough lobby group with the same diet as 'Spaw, to take on the big 3 automakers for starters, and everything else will cave into submission.
