  • Patent number: 7425776
    Abstract: A multiple generator having a vertical post and multiple vertical tubes has the generators positioned vertically one above the other. Each is cylindrical in shape and has two rings separated by connecting fins. The cylinders vary in size with the top being the smallest, the middle or second being larger and the third being the largest. With low winds, only the smallest generator turns. As wind velocity increases, the small generator rotates faster until clutches in a clutch ring move outwardly until they engage and secure to the second generator so both generators move together. As wind speed increases, clutches on the second generator move outwardly until they engage and secure to the third generator and all generators now rotate together. Thus varying amounts of electricity are generated depending on the wind speed and which generators are active. Each generator has its own rotating shaft with ball bearings between the post and first tube and between the first and second tubes.

  • Patent number: 7314104
    Abstract: A steam driven road vehicle having a firebox, a boiler, a drive mechanism operated by steam from the boiler, a water supply supplying water to the boiler, and a drive connection connected between the drive mechanism and an axle of the vehicle. A fuel bin is supported by the vehicle frame holds a supply of fuel to be fed to the firebox. A power driven conveyor conveys fuel from the fuel bin to the firebox. An electrical system is made up of a plug-in element which connects with an electric source, and a preheating element on the boiler for producing preheat in the boiler. A heat control device controls the temperature of the output of the preheating element, and a time control device is arranged to energize the preheating element prior to driving the vehicle.
