Methanol powered ships

As a commercial pilot, I can assure you that no one is flying around in alcohol powered airplanes except as a stunt. The same tank gets you about half as far, which is a non-starter for aircraft. I suspect this could be an issue with ships as well. In addition, methanol (wood alcohol) mixes with water. Ask anyone with craptastic ethanol-gasoline in their boat how much fun that turned out to be :mad:
