The solar system form was formed about 4.5 billion years ago from a massive cloud. The massive cloud contained hydrogen, helium, and pinches of heavier elements such as oxygen, carbon, nitrogen, silicon, and iron. The materials in the massive cloud clumped together and the largest clump became a prostar. Compression of the prostar due to gravity caused the fusion of hydrogen into helium.
Thermosiphon takes place When the sun comes up. The water in the evacuated solar tube panel begins to circulate from the solar geyser through the evacuated solar tube panel and back. The process is continued throughout the day, until the sun goes down. We adjust your geyser thermostat to 40′C so that on days where there is absolutely no UV rays around, you will still have warm water. If there is a power failure, thermosiphon effect will still take place, which guarantees hot water irrespective of power failures.
