In the 19 sixties, soviet scientists used these cyclo propane rings to design a special rocket fuel called sinton. But their making of sinton was really, really expensive and it also involved fossi fuel feed stock. So they wanted to see if they could do that in a lab in a controlled way. The scientists found the enzyne s that make the super energy dense cyclopropane rings, and they tweaked them. They added some extra to the bacteria, and they were able to create an assembly line inside of the bacteria. You put in sugar and you get out jetfield.
