Abstract

The invention is a hybrid wheel apparatus with a hybrid roadway apparatus that greatly reduces the energy lost due to rolling resistance where operation is on the hybrid roadway, but the system is configured to allow operation on conventional roads as needed. The hybrid wheel system is a steel wheel used in combination with a rubber tired wheel. The hybrid roadway is a low profile steel rail fixed to the otherwise conventional road surface, which is preferably concrete but could also be the very common asphalt composition. Where roadways are appropriately equipped with rails, the rail top surface is elevated over the roadway surface, and dimensions are set so that most of load force is carried on the steel wheel for general forward travel. Where the rail is absent the load is carried on the rubber tire, and the steel wheel is elevated above the roadway surface such that contact between the steel wheel and the roadway is prevented.
