In Brazil they sell ethanol 2% water (Alkohol in Portuguese) in every gas station and it's cheap really cheap.
Now if you can just get sugar cane to grow in the uk and your set.
Cars in brazil run like *****... Ethanol is not a good fuel for hp or milage. Its only the next cheapest thing to oil. Most race cars run methonal which has some very unquie properties. The more water ethanol picks up the thicker it flows and the leaner your engine will be. You can only jet for one type of fuel too much water and it will start to effect performance.
