A structurally integrated modular system for energy recovery from vehicular traffic as further disclosed. The system comprises an “X” & “Y” axis horizontal array of Linear Electromagnetic Generators, (LEGs), in a close packed hexagonal or other shaped structural grid, as further disclosed. Each LEG is spring-less, using a high strength main core magnet, and a fixed lower magnet to repel the main core magnet at a designed coercive restoring force. The plurality of LEGs are contained within Modular Prefabricated Structural Sandwich Composite Panels, (MPSSCPs), designed to be placed upon a roadway surface, (whose upper surfaces are flexible and lower surfaces semi-rigid). The resultant energy recovery is thereby converted to electric power and heat. The MPSSCPs, and their accessory panels are thereby installed upon a roadway bearing surface to generate clean electric power and heat, which thaws ice and snow, when and where necessary.
