<p>A method for powering a vehicle comprises, in one embodiment, receiving infrared radiation emitted as heat from a roadway surface, and converting energy of the infrared radiation to a form of energy that is useful for providing power to the vehicle. In a further embodiment, a method for powering a vehicle comprises thermally contacting a heat-conductive device to a roadway surface, and converting energy conducted by the heat-conductive device to a form of energy that is useful for providing power to the vehicle. In another embodiment, a method for powering a vehicle comprises: insulating a first region of a road's surface with a material that transmits visible light but blocks infrared radiation, while leaving a second region of the surface uninsulated; conducting heat from portions of the road beneath the first region, to the second region; receiving infrared radiation emitted as heat from the second region; and converting energy of the infrared radiation to a form of energy that is useful for providing power to the vehicle. In yet another embodiment, a method for powering a vehicle comprises receiving light emitted from a concentrated light source, and converting energy from the concentrated light source to a form of energy that is useful for providing power to the vehicle.</p> |
