一辆车顶行李架上复盖着太阳能发电装置的“大众Passat”牌汽车已完成了一个阶段的行车试验,这种置于车顶的小型太阳能发电装置是由“通用电力公司”(AEG—Telefunken)制造的,其输出功率约160W。它可将太阳能直接转化为电流,以补发电机输出电力之不足,和为蓄电池充电。这将使汽车的汽油消耗量减少5%!目前,太阳能发电装置的造价仍很高,在 A Volkswagen Passat car with a solar-powered generator set on a roof rack has completed a phase of traffic test. The small solar-powered generator set on the roof is made by AEG- Telefunken) manufactured, the output power of about 160W. It converts solar energy directly to current to make up for the lack of output power from the motor and to charge the battery. This will reduce the car’s gasoline consumption by 5%! At present, the cost of solar power plant is still high, at
