Ethanol In Use by Peter Bursztyn Pure ethanol fuel is available in Brazil where many cars have been designed to use it. 100% ethanol is unlikely to ever be used in North America or Europe. This is because ethanol is

Ethanol: Unintended Consequences by Peter Bursztyn When the idea of biofuels was first suggested, it should have been obvious that increased demand for crops destined to become fuels would raise their price. In the U.S.A., the crop of choice has

Ethanol: Efficiency and Availability by Peter Bursztyn In Brazil and a few other tropical countries, ethanol is fermented from sugar cane. This process is far less energy intensive (partly because human labour inputs are greater than in North America). It

Ethanol by Peter Bursztyn Many manufacturers are now building “Flex Fuel” vehicles. “Flex Fuel” means the engine can use pure gasoline, or E-85 (ethanol with 15% gasoline), or any mix between these two. The premise is that, since E-85 is
