Here are links to alternative fuels. These will give information about the use of Ethanol as a fuel, and how to make the best use of ethanol through engine modifications. . . . Running on alcohol - all you wanted to know           a local copy if that link fails           . . . Another article on use of ethanol as a motor fuel.           This has numbers of ideal stoichiometric ratio for fuels, and where normal petrol is about 15:1 the ideal for ethane is around 9:1

Information on energy content of various fuels, and other interesting facts. The power that can be produced by a fuel is directly related to how much energy is in the fuel. For a given unit amount of fuel, such as a gallon or a liter, a fuel with more energy per unit will produce correspondingly more power than a fuel with less energy per unit. Now, in real life, you are assuming that the fuels being compared are all usable in the same engine. Just because diesel fuel has more energy per gallon than gasoline (and it does) does not mean it will produce more power in your gasoline engine. Sorry. The fuels being compared both have to work in your engine. A higher Octane Number by itself does not mean the fuel will produce more power. The Octane Rating is a measure of how well a fuel resists preignition and detonation. Water will never preignite or detonate so it would test off the scale for octane rating ... as a fuel additive, you probably wouldn't be happy with it. . . .

Most of this information came from a search of the web looking for "fuel energy content" and such search arguements. ___________________________________________________
