As this article points out, Virgin Galactic is already planning on using greener propulsion. I think it is great that someone is trying to eliminate the cause of excessive greenhouse emissions, but I think it is lame to point out an industry that is already on the cusp of alternative propulsion. The best way to ensure they don't continue R&D on alternative propulsion is by keeping those companies busy trying to deflect criticism and help mold related legislation.
