Trash into electricity

A few years ago, researchers from Purdue University developed a machine for the U.S. Army that would convert trash into electricity. The garbage is separated inside the machine into solid and liquid wastes and then gasified to power a turbine. The machine, once deployed, cuts down on the amount of trash that would otherwise be buried or burned in an open pit while also reducing the amount of fuel required to be transported into the field.
