Carraway's process was far more complex than Margiotta's. Margiotta simply centrifuges a mixture of water and crude oil and since oil is lighter than water, the oil separates from the slop and they run it into a tank and sell it to Shell. Carraway heated lubricating oil such as old crankcase oil from a service station. When hot enough, the long lube oil molecule "cracks" and makes a shorter molecule ("diesel" or heating oil) and an even shorter molecule which is a gas and is used as a fuel to help the heating. Neat, eh? What could go wrong?
I am an individual who likes the KISS method. Keep It Simple, Stupid. Centrifuging, helped along with a dose of microwave heating to help us through the winter, is my kind of simplicity. We don't need no stinking patents, OK? Besides, I have seen a beautiful patent misjudged in court because of a lack of understanding of its true value. Courts have a way of being distracted by artful flimflam which negates patents. It is far better to understand what you are doing and do it better than the other guy.
