Most people will agree that trash is piling up everywhere. And most people also agree that we need to decrease the amount of fossil fuels used on a routine basis.
Thanks to modern marvels of science, maybe this will be the norm in the future, as scientists at Purdue have developed a portable generator that turns trash into fuel. The "tactical biorefinery," as it's called, can process multiple kinds of waste, which in turn can convert the waste into fuel.
As it stands now, the biorefinery initially runs on diesel oil for a few hours until it has enough trash to go on its own. While that seems a little oxymoronic (burning fuel to make fuel?), the generator is still efficient. With continued progress, maybe we'll see more of this type of ingenuity in the future.
