录音中指出maze-based E85 fuel也即是an 85% ethanol/petrol mixture，在提到目前E85的市场后，录音中指出“Better fermentation techniques, based on biotechnology, may multiply that many times”，可见以生物科技为基础的更好的发酵技术会促使乙醇燃料市场的扩大。
【录音原文】
Maze-based E85 fuel (an 85% ethanol/petrol mixture) is already on sale in parts of America. In July, the National Ethanol Vehicle Coalition launched a project to promote greater use of E85 in Wisconsin, Missouri, Colorado, Minnesota, Michigan and Illinois.
