Abstract:
A device for generating electrical energy from kinetic energy of wheeled vehicles on a roadway, comprisingat least one fluid pressure vessel arranged in the roadway, said pressure vessel comprising at least one pressure chamber that is compressible substantially perpendicular to the roadway, a flexible cover sheet over the pressure vessel for transmitting force from the wheels of vehicles on the roadway to the pressure chamber, the cover sheet having a non-slip surface, at least one circuit for said fluid, said pressure chamber being a component of said fluid circuit, and at least one turbine/generator unit that is disposed in the fluid circuit for generating electrical energy from the flow of the fluid, wherein said pressure vessel is configured as a chest that is elongated in the roadway direction and in the front and rear sides of which fluid circuit pipes are ported, wherein elongated pressure chambers are formed in said pressure vessel by partitions, said pressure chambers permitting fluid flow substantially only parallel to the longitudinal direction of said pressure vessel, and wherein the diameter of the pressure chambers is diminished from the front side to the rear side of said pressure vessel.
