PURPOSE:To collect solar heat efficiently by a method wherein layers of minute glassy spheres containing metallic material inside thereof are formed in the shape of a bowl inside the hoenycomb hollows of a honeycomb-shaped substance. CONSTITUTION:The layer 5-7 of the minute glassy spheres 8 containing metallic material 9 inside thereof are formed in the shape of a bowl inside the honeycomb hollows 3 of the honeycomb-shaped substance 2 having a bottom surface 1 being excellent in heat conductivity. By this constitution, conducted heat and radiant heat absorbed by the minute glassy spheres 8 can be utilized simultaneously and thereby the solar heat can be collected efficiently. |
