Patent ID: 8079346

Claim:
A method of causing an engine of a vehicle to consume less fuel, said method comprising: adding a semiconductor to molten iron during steel making, thereby providing an iron-semiconductor alloy; rolling the iron-semiconductor alloy under load, thereby providing a sheet; placing the sheet on the vehicle, proximate to the engine; and severely vibrating the semiconductor by irradiating the sheet with sunlight or white light having wavelengths of from 1 nm to 1 mm, thereby generating vibrating-electromagnetic waves as a result of electrochemical potentials being created across iron and semiconductor crystals of the sheet, and thereby enhancing vibrating-electromagnetic waves generated from the iron-semiconductor alloy and causing the engine to consume less fuel, wherein content of the semiconductor is 1-10 wt. % of the iron-semiconductor alloy and content of iron is 78-98 wt. % of the iron-semiconductor alloy.
