Plastic bags have become the bane of our existence. They pollute our waterways, get tangled in trees and bushes, and take hundreds of years to break down into smaller pieces. But Japanese inventor Akinori Ito has created a household appliance that converts ubiquitous plastic into fuel. A video shows Ito placing plastic bags, styrofoam containers, and other random bits of trash into a tabletop machine that melts them and condenses the gas released to produce usable oil. The highly efficient, non-polluting machine can process polyethylene, polystyrene and polypropylene (but not PET bottles), and it can convert 2 lbs. of plastic into a quart of oil using just 1 kilowatt of power.
