Pimental study was picked out of about 10 studys of ethanol. His calculations?hehe were the lowest of the 10 studys. So basing everything about ethanol on the lowest calculations of 10 studys could perhaps mean that Pimental is off by 90%. And his synopsis of the study he set out to prove was that ethanol was not feasable. So being a biased researcher, naturally his summary will support his theory.
Why should anyone believe 10% of the people are the only ones who are right and everyone else is stupid?
So in your world, majority determines scientific truth? Thermodynamics isn't determined by popular vote. If a million tree huggers fervently belive something and the objective reality is the opposite of their belief, their belief is still wrong.
