A Future Fueled by Grass Clippings

New technologies are like candy. They're short-lived, in that they are quickly replaced by something better, and sweet in the sense that they often provide much needed services. A good example is ethanol production for use as a fuel source. The original method involved using corn starch, because it's easier to break down into ethanol than, say, cellulose. However, there are some companies out there who are looking into harnessing cellulose as a source of ethanol. Though the process is still more expensive than producing ethanol from corn, there are hopes that within 6 or more years it will be as cheap, if not cheaper. Ideally, I'd like to see a technology like this miniaturized so that people can make their own ethanol fuel from their own grass clippings. Mow the lawn and get a few more miles out of your car at the same time.
