Yes ethanol is very hydroscopic. However, I have read a number of papers that have been written on the successful use of ethanol in the manufacture of biodiesel. There are ways of extracting the H2O from it. If you really wanted to avoid fossil fuels, brewing your own alcohol and using it to make biodiesel would be the ultimate way to do it. The process would likely not be justifiable economically if you wanted to include the value of your time. If you considered it a hobby that was self supporting it would be kind of cool.
