I think the last 24 months have started a little bit of a momentum for alternative energy/propulsion systems. I believe that whatever happens to the price of oil, up or down, I don't think you will see this surge in innovative technologies die out like in years past. I believe that some very bright people can smell some very lucrative patents. American Free Enterprise still makes us the greatest country in the world. It will be interesting to see what the next 5 years will bring.
