Promote hydrogen,ethenol or bio-diesel vehicles

Car manufacturers know that gasoline cars are money makers.
We support other questionable nations with our “oil dollars”.
The technology is far enough along in alternative fuel vehicles but we need the demand for them to start seriously producing them. What are we waiting for $5 per gallon of gas? Also the government could give financial incentives. All countries should work together in this project to end fossil fuel. While are all the countries are together we could rent an adjoining conference room and have the world leaders chat about peace in the world. Too bad John Lennon is no longer with us….
