One Man's Trash Bags Are Another Man's Heat Source

A Japanese inventor has created a machine which can melt down plastics - such as bags and bottles - into a crude oil that can be used as energy in a home heating system. In one hour, 1kg of plastic (polypropylene, polyethylene and polystyrene... you pick!... mix and match!), can be melted down into a quart of the oil, which is good for a kWh worth of energy. The $US10,000 machine can be purchased now. [PhysOrg via Wired]
