For example, the concentration of NO: is already above the regulated value in the Tokyo metropolitan area and still increasing. This deterioration can be attributed mainly to an increase in the number of automobiles in the area. Another serious environmental issue is 'urban warming (i.e. heat islands)', which is caused by concentrated consumption of energy in urban areas. In this study, a new environmentally-compatible vehicle is designed to mitigate urban warming, air pollution and CO: emissions. Principal specifications for an optimal design will
