NOVELTY - A horizontal axis wind turbine (A) has solar panels fitted on a 7-inch raised roof to produce electrical power to an axle electric motor or in-wheel electric motors and topping up battery pack. The turbine also produces mechanical power to twin generators by reducing ducting or sealed boxed ducting (C) within the raised roof and existing roof. One-inch adjustable slats at the front of ducting are electrically controlled at the dash board to counter changeable weather conditions. The battery pack is for starting up the motors at low speed.    USE - Horizontal axis wind turbine for vehicles, such as all-electric vehicle with displacement of up to 1600 cubic centimeters and equipped with axle electric motor and in-wheel electric motors. Can also be used in combination with internal combustion engines in vehicles, such as larger cars, vans, container trucks, rail coaches, and ships (All claimed), with displacement over 1600 cubic centimeters. Can also be used in other vehicles e.g. hatchback vehicles, cruise liners, container and cargo ships.    ADVANTAGE - The axle and in-wheel motors and the battery pack are powered and topped by solar panels, reducing fuel consumption of engines as well as reducing carbon dioxide emissions. The slots at the front of the ducting are electronically controlled at the dash board to allow most efficient air pressure to get maximum power from the turbine to convert mechanical power to the twin generators. Use of raised roof, preferably extended plastic carbon fiber cover roof, with design identical to original roof keeps added weight to vehicle to minimum. Ventilator grill at rear wall of vehicle between original and raised floors ensures ventilation to twin generators and battery pack.
