Abstract
We have studied the solar energy that is attracting attention as an alternative to petroleum energy. In this experiment, using two types experiment devices of condensing point type heat collector and condensing line type heat collector. The experimental purpose is efficient heat collection and using heat efficiency. In the experimental devices were fabricated, the condensing line type heat collector get the amount of about 100W for about an hour and a half, was able to generate fresh water more than 200g. The condensing point type heat collection get the amount of about 160 W for about 7 minutes. The purpose of future of condensing line type heat collector is improving the efficiency of heat collection and increasing the amount of freshwater recovery. The purpose of future of condensing point type heat collector is improving the efficiency of heat collection and considering the use efficiency of heat collected. In the current thought is in a device with a function of hydrogen production.
