Pseudoscience describes any belief system or methodology which tries to gain legitimacy by wearing the trappings of science, but fails to abide by the rigorous methodology and standards of evidence that are the marks of true science.
1 Flex-fuel hybrid electric and flex-fuel plug-in hybrid are two types of hybrid vehicles built with a combustion engine capable of running on gasoline, E-85, or E-100 to help drive the wheels in conjunction with the electric engine or to recharge the battery pack that powers the electric engine.
When used in cars and trucks, ethanol is usually mixed with a little gasoline to improve fuel economy. The resulting fuel is called E85, denoting 85 percent ethanol and 15 percent gas. In 2007, there were 5.5 million Flex Fuel Vehicles on the road in the U.S. that could run on E85 fuel. Unfortunately, there were only 1,208 E85 filling stations -- less than 1 percent of the total filling stations in America.
