<p>A road way electrical generator comprises a cylinder or roller 5 disposed in a chamber 1 formed beneath a road surface 2. The roller 5 has a plurality of magnets equally spaced around the circumference of the cylinder so that it couples with a vehicle passing overhead on the road 2. The magnets may be retained in grooves so that they are flush with the surface of the cylinder 5. The generator 15a may be mounted within the cylinder 5 and driven by epicyclic gears 21.</p> |
