Abstract

An apparatus for generating electrical energy from a vehicle traversing a predetermined section of a roadway. A platform member is disposed on such section of roadway and a plurality of air bags are disposed between the platform and the road surfaces. The air bags are compressed as the vehicles passes over the platform and the compressed air is collected in a storage tank and fed to a generator for generating electrical power. There are also a plurality of coils and magnets disposed between such platform and road surface. The magnets pass through the coils when a vehicle passes over the platform to generate electricity. The electricity is stored in a DC storage unit and later converted to Ac in a DC/AC converter. The electricity generated by both means is delivered to a power distribution system.

Dependent claims

An apparatus for generating electrical energy as a vehicle traverses a predetermined section of a roadway, said apparatus comprising:

(a) a platform member disposed over said predetermined section of roadway;
(b) a biasing means disposed between a top surface of such roadway and a bottom surface of said platform member for returning said platform member to a raised position after such vehicle has passed over said platform;
(c) a plurality of coils engageable with and disposed in a predetermined pattern on an upper surface of such predetermined section of such roadway are engageable with and disposed beneath said platform member;
(d) a plurality of magnets engageable with said bottom surface of said platform member, each magnet member of said plurality of magnets disposed to pass through an interior portion of a respective one of each coil of said plurality of coils when said platform member is depressed by such vehicle traversing said platform member and rising up through said each coil of said plurality of coils when such vehicle has passed and said platform member returns to its original position thereby creating an electrical charge;
(e) a DC storage unit disposed closely adjacent said platform member having a first electrical connection with said plurality of coils for storing such DC current created by said plurality of magnets passing through said plurality of coils;
(f) a DC to AC converter, having a second electrical connection with said DC storage unit, disposed closely adjacent said DC storage unit for converting such DC current generated by said plurality of coils and converting such DC current to AC current;
and
(g) a third electrical connection means from said DC to AC converter to a power distribution system for delivering electrical power generated by said plurality of coils to such power distribution system.

An apparatus for generating electrical energy as a vehicle traverses a predetermined section of a roadway, said apparatus comprising:

(a) a plurality of air bags engageable with and disposed on an upper surface of such roadway in a predetermined pattern to be compressed by such vehicle;
(b) a compressed air storage tank disposed closely adjacent such roadway;
(c) a first fluid communication means connected at a first end to each of said plurality of air bags and at a second end to said storage tank for communicating compressed air from said air bags to said storage tank;
(d) a platform member engageable with and disposed over said plurality of air bags for such vehicle to pass over thereby causing said plurality of air bags to be compressed and communicate said air to said storage tank;
(e) a biasing means disposed between such top surface of such roadway and a bottom surface of said platform member to return said platform member to a raised position after such vehicle has passed over said platform member and thereby allow said air bags to return to a working position;
(f) a first check valve means disposed in said first fluid communication means, said first check valve means being open to said storage tank as such vehicle is compressing said platform member and in a closed position when such vehicle has passed over said platform member;
(g) a second check valve member connected at a first end thereof to said first fluid communication means and disposed in fluid communication at a second end thereof to atmosphere such that said second valve means is in a closed position as such vehicle is traversing said platform member and in an open position after such vehicle has passed over said platform member;
(h) an electrical generator disposed closely adjacent said air storage tank;
(i) a second fluid communication means connected at a first end thereof to said storage tank and at a second end thereof to said electrical generator for communicating sufficient air thereto to generate electrical power;
and
(j) a connection from said electrical generator to a power distribution system for delivering power generated by said electrical generator to such power distribution system.
