Use solar water to boil water to generate electricity for heating. The hot water in the daytime is stored in a large "warm bottle" water tower. The water tower should be insulated and stored at night to ensure that it can be heated at six or seventy degrees. In fact, heating requires less water temperature, and it is enough to not freeze the frozen feet. The solar steam turbine generates electricity, and the hot water is converted into steam by the concentrating mirror, and the temperature reaches the boiling point. When it is cloudy, it is slightly lower, and the electric battery can be used to add fire. The problem of heating in the community is not big.
