cars and gas are a great way of transportation and fuel. Before you yell at me for saying fossil fuels are ok let me explain how we should be using gas in our cars. Now a' days we are just pumping gas into our carboratours which i must say isnt very smart. The concept im about to explain has been done before but numerous threats from oil companies have been keeping the concept from being commercialized. The concept is that our carboratours can run off of super-atomized gas vapor. How is it super atomized you ask simple, low heat! If you had copper tubes going from the top of your fuel tank that the vapor could flow into. Then the other end of the copper tubes are wrapped around the some part of the car (i forget) to warm the vapor, this super atomized it and could be fed into the carboratour the car could then efficiently run off the vapor. This concept has had rumors of MPGs between 75 and 300. This was first thought up by a Canadian engineer in the 1800's. He was very successful with it and patend it, he was a very humble man and did not commercialize it (although he did make a couple for his family and friends) . The patent might still be floating around if you can find it. Fossil fuels are efficient just not to enviromentaly friendly.And of course if this was to be commercialized oil companies would lose a hell lotta money .Let me know if you have any questions about this
