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.
Sure, they are gasoline engine vehicles, but theyâve been modified to operate smoothly on any mixture from straight gasoline and E10 up to E85 (a blend of 85 percent ethanol and 15 percent gasoline). In addition, modifying a conventional auto to make a flex fuel vehicle is inexpensive. FFV technology is estimated to cost roughly $100 per vehicle at the time of manufacture. Whatâs more, retrofit kits are available for many cars for about $400.
