German inventor Peter Eckhoff has created an engine inspired by the movie "Back to the Future." Eckhoff's engine uses empty plastic bottles to power his VW.
Peter Eckhoff's engine was developed in conjunction with Jean-Marie Stankovicc-Gansen and involves a part that can be filled with empty plastic bottles. This part is heated by the car's traditional engine, burning the bottles; the resulting gas is used to help power the engine.
Peter Eckhoff's engine saves about 30% more fuel with 125 grams of plastic trash--about 3 bottles per 100 kilometers.
