The increasing need for cleaner and sustainable energies provoked by the contamination emitted to the atmosphere made by petrol sources had made ethanol an option to reduce those emissions by using a renewable, clean product as vegetable to impulse diesel engines. There are some main advantages of ethanol is that it can be used in existing engines, vehicles and infrastructure with practically no changes. Ethanol can be pumped, stored and burned just like gasoline, and can be used pure, or in blends with gasoline fuel in already tested blend mixtures. Power and fuel economy using ethanol is practically identical to gasoline, but with the added benefit of emitting less contamination and byproducts that can be used as livestock feed. In this book we will try to expose the chemistry behind the processing of vegetable sugars (waste or clean), the equipment, safety measures and set up for the area to process a batch of ethanol at home.
