Abstract: PURPOSE:To generate electricity under solar heat through a very simple construction, by sealing a cathode, a plate, argon gas and so forth in a heat-resisting glass container whose top has a convex lens for condensing sunlight, to constitute an electricity generation tube. CONSTITUTION:A cathode 1 and a plate 2 are housed in a heat-resisting glass container 4 whose top has a convex lens 3 for condensing sunlight. The cathode 1 and the plate 2 are secured to a base 6 and legs 5 by pillars 7. After the container 4 is evacuated of air, argon gas is sealed therein. A vacuum tube A for electricity generation by solar heat is thus constructed. The cathode 1 is heated by the condensed sunlight to emit thermoelectrons to take out a voltage across a resistor 8. The electricity generation by solar heat is thus performed through a very simple construction at a very low cost.
