It takes some mechanical aptitude, but you can make your own fuel by fermenting appropriate feed stocks into 96 proof alcohol.This form of fuel is called alcohol fuel also called ethanol.Many forms of agricultural biomass can serve as feed stock. Ethanol is such an attractive fuel option is that it’s basically liquid energy. Ethanol is a clear liquid that packs a lot of energy into a usable, storable, and transportable form. Only petroleum can compete with ethanol on an energy-per-volume basis. But ethanol has an added benefit in that it’s oxygenated, meaning it has oxygen in its molecular structure, which results in a cleaner burn.

Air Fuel Synthesis, a small British company, has found a way to combine basic elements from air and water into usable fuel.Since August, England-based Air Fuel Synthesis has created five liters of gasoline by combining carbon dioxide extracted from air with hydrogen from water to form a basic hydrocarbon, the essential ingredient of gasoline.
