Solar powered vehicles

Cells made from GaAs are more costly than silicon cells, because the production process is not as well developed, and gallium and arsenic are not abundant materials. GaAs cells have been used when very high efficiency is needed regardless of cost such as required in space applications. They were also used in the Sunraycer, a photovoltaic-powered electric car, which won the Pentax World Solar Challenge race for solar-powered vehicles in 1987. It ran the 3000-km from Darwin to Adelaide, Australia at an average day time speed of 66-km per hour. The 1990 race was won by a... [Pg.202]

The Sunmobile SunVee is a solar neighborhood vehicle. Solar electric panels are integrated with the body to charge batteries which power an electric motor. The neighborhood range is about 30 miles with a top speed of about 25 miles/hour. The Sunmobile is based on a commercial four-wheeled, two person, pedaling bike, called a Rhoades Car. [Pg.257]

The US military has a need for extreme long-duration unmanned air vehicles (UAV), and a hydrogen-powered, fuel cell-driven electric aircraft is a leading candidate. Without an internal combustion (1C) or jet engine, a fuel-cell UAV would be very quiet. Furthermore, there is the potential to electrolyze effluent water (or airborne water vapor) using solar power, giving the UAV an almost unlimited flight duration. [Pg.108]

Calculate the area of solar collection necessary to power a 300-kW lighter-than-air vehicle by means of photovoltaic cells (20% efficient), electrolyzing onboard water. Assume a 200-m-long dirigible (as an approximation, take its shape as cylindrical with a radius of 20 m). Could a hydrogen-lifted vehicle be solar powered but fly during darkness (Bockris)... [Pg.381]
