So cars and trucks are not the only vehicles that use fossil fuels and I have been looking at different technologies, some old and some new to improve MPG's. Most of these technologies if used to mod 1 car or truck are very expensive, but if it was standard on a car or truck that was produced in the hundreds of thousands, the cost is much more affordable. Up first is the technology behind diesel locomotives: [*=2]http://science.howstuffworks.com/transport/engines-equipment/diesel-locomotive.htm The important stuff starts on page 4 through 8. To take this information and apply it to a silverado: Why can't I have a 2 stroke 4 cyclinder engine in a 1500 silverado that takes a third the space of the of the 5.3L v8. Couple it with a generator that provides electricity (48volt system) that charges 6 x 8volt batteries. These batteries then power pancake traction motors mounted where the wheel hub and rotor should be with different gear ratio's to allow the change in miles per hour from 0 to 150 mph, etc. And then user an air powered drum brake. Apparently mini copper is smarter than gm and is already working on a similar system.

Next is this guy... just google Johnathan Goodwin. [*=1]http://www.fastcompany.com/60868/motorhead-messiah Turbine Jet engines are some of the most fuel efficient engines around. Technology at universities such as NCSU are working on "nano tubes" and nano technologies where they can build turbine engines smaller than the thickness of human hair. Taking the diesel locomotive as an example........ what if they replaced that 2 stroke v12 with 11.x L per cylinder engine with a jet turbine that was more fuel efficient. How about a smaller jet turbine like the one Johnathan is using that would fit in place of the 5.3L in my silverado that is really using 200 year old tech and making the people in oil rich countries richer while we complain about gass and diesel prices? Johnathan was invited to visit GM and their engineers told Johnathan that GM told us it was impossible to do what he did. Now I wish I could find the link for the car in Australia that uses this engine, but I coudn't.....So here is an article from MSU in Michigan showing the same concept... Why do we need a transmission, we loose about 25% of fuel econ through the transmission.
