Sheet Cake Ethanol

Limited sources of energy are a cause of national economic woes and international belligerence. A noble goal, of course, is to combat these woes by increasing use of renewable sources of energy (like wind and solar). But along the way, it is also important to be efficient about using the sources of energy that have already been produced. Which is why I am often disappointed to see large quantities of sugary cakes go to waste after parties in my department's break room. I propose to designate a central cake disposal location in each city (maybe several in larger cities) so that left-over cakes can be collected and fermented into ethanol for use in city buses. This location might contain several bins to allow for separate collection of cakes, brownies, muffins, etc. To increase awareness of this effort, bumper stickers should be produced for buses running on this fuel: "This bus is powered by the skinny people in your office that didn't have a piece of cake."
