Abstract

Field of application: ecology, atmospheric purification. Used to focus solar rays at altitudes between eight thousand to twelve thousand metres, between the ozone layers, and above for complete combustion of C.F.C. chlorofluorocarbons. It can also be used at lower altitudes for complete combustion of other harmful gases suspended in the atmosphere.<IMAGE>
