Automobiles solar-powered

Photochemical air pollution in the troposphere is induced by the action of solar ultraviolet radiation upon mixtures of NO (NO and N02), SO (S02 and sulfates), and reactive hydrocarbons (mostly olefins) emitted in the atmosphere by automobiles and power plants. 

Be familiar with the design of a representative array of nine chemical products. These products include small hemodialysis devices, solar desalinators, hand warmers, fuel cells to power automobiles, and thin silicon films that coat microelectronic devices. 

Atmospheric Pollutants. Ozone is present in the earth s atmosphere both as a result of uv photolysis of oxygen in the upper atmosphere and as a result of reaction between terrestrial solar radiation and atmospheric pollutants such as nitrogen oxides and hydrocarbons from automobile exhausts. It is a powerful oxidant that can react rapidly with elastomers and other imsatin-ated polsrmeric materials to cause stiffening and cracking, particularly imder mechanical stress. Other common air pollutants include sulfur oxides, hydrocarbons, nitrogen oxides, and particulate matter such as sand, dust, dirt, and soot. Some of these may react directly with organic materials, but have a much more severe effect in combination with other weather factors. 

The sunlight incident upon a 1 square meter area perpendicular to the line of transmission of the solar flux just above the earth s atmosphere provides energy at a rate most closely equivalent to (a) that required to power a pocket calculator, (b) that required to provide a moderate level of lighting for a 40-person-capacity classroom illuminated with fluorescent lights, (c) that required to propel a 2500-pound automobile at 55 mph, (d) that required to power a 100-watt ineandescent light bulb, (e) that required to heat a 40-person classroom to 70T when the outside temperature is -10°F.
