This is madness! In addition to the affinity to water that Ethanol has, consider this:
Gasoline is a saturated hydrocarbon, with a fixed amount of energy, in each gallon.
Regular gasoline has an energy density of 44.8 MJ/kg or 125,000 BTU/Gal
Ethanol has an energy density or 31.1 MJ/kg or 84,600 BTH/Gal
energy density = amount of energy stored (available) in a given volume or given mass
MJ = megajoule
kg = kilogram
Do the math
Pure Ethanol consumption in an engine is approximately 51% higher than for gasoline since the energy per unit volume of ethanol is 34% lower than for gasoline.
In a ‘pump gas’ mix of up to 10% Ethanol. The energy density is approximately 120,960 BTH/Gal, that’s 3% less energy than a gallon of non-entahnol gasoline, and you need 4% more to get the same amount of energy.
The bottom line, you need to burn 4% more of a ‘pump gas’ mix of up to 10% Ethanol, to get the same amount of energy, or move your car or boat, the same distance, at the same speed.
