Abstract: A method and apparatus for producing useful work by utilizing the weight of moving traffic by incorporating in a roadway or traffic-way a readily deformable chamber which is filled with a fluid arranged so that the weight of a vehicle in passing thereof affects a displacement of the fluid therein. The energy of the displaced fluid in turn is translated into mechanical or electrical energy.
