1. In combination with a ground vehicle powered by a waste heat generating electric motor, a space cooling system comprising:

  • A. an air-cooled condensor for converting refrigerant vapor to a liquid;

    B. means including an air-cooled absorber wherein a refrigerant gas is dissolved in a weak refrigerant-absorbant solution for thus forming a strong refrigerant-absorbant solution;

    C. generator means for heating said solution comprising;

    a heat extracting conduit passing through the housing of said electric motor for conducting the strong refrigerant-absorbant solution through the motor in a heat exchange relationship therewith simultaneously with a generation of waste heat by said motor, whereby waste heat generated by said motor is transferred from the motor to the strong refrigerant-absorbant solution, a black body, flat plate solar collector mounted on said vehicle and connected to said conduit in solution-receiving relation therewith for transferring solar heat to said strong refrigerant-absorbant solution for converting the strong refrigerant-absorbant solution to a vapor and a residue of a weak refrigerant-absorbant solution, means for directing the weak refrigerant-absorbant solution to the absorber and delivering said vapor to the condenser, whereby the vapor is converted to a liquid refrigerant;

    D. a space cooling evaporator connected to the condensor for receiving and converting the liquid refrigerant to a gas;

    E. means connected between the absorber and the generator for directing the weak refrigerant-absorbant solution to the absorber from the generator and means connected between the absorber and the evaporator for delivering to the absorber refrigerant gas to be dissolved in the weak refrigerant-absorbant solution for thereby providing a strong refrigerant-absorbant solution output from the absorber.
