If water vapor drives a turbine to produce electricity like a thermal power plant, it has nothing to do with density, as long as the boiling point is low enough to generate enough steam.
If the gravitational potential energy of water is used like hydroelectricity, there should be no other liquid capable of absorbing the thermal energy of the sun and converting it into potential energy at such a large scale, and high density liquids such as mercury and tetrachlorine, chemical carbon, etc. are all toxic and cannot be stored in the open like a tank.
Humans can produce water.
That’s exactly what an Australian inventor did. Max Wesson is the creator of the Wesson windmill, a machine that used wind energy to collect moisture from the atmosphere. Wesson pointed out that the total amount of water vapor in the air around the world at a depth of about 0.62 miles above the ground is about "1 trillion liters." Additionally, this water is replaced every few hours as part of the water cycle.
Wesson's windmill used a refrigerant to cool its blades, which he named Max Water. The blades are positioned vertically rather than diagonally, so even the slightest wind can cause them to spin. The cooling blades cool the air, causing the water vapor to condense and become liquid water again, and this condensation is then collected and stored. Wesson's windmill can collect up to 2,600 gallons (11,830 liters) of water from the air each day.
A brief description of the role of water
1. Water can be used for hydroelectric power generation, shipping, bamboo transportation, climate regulation, beautification. the environment, etc
2. The usesions of water in life include: consumption, powering all things, industrial use for cooling, heating, dissolving, cleaning and synthesizing, agricultural irrigation and breeding, as well as the development of water sports and entertainment. etc.
3. Water can save people trapped in the desert and give them hope of survival. Crops cannot live without water. Because there is water, crops can grow well.
4. Water can help people generate electricity. Water can irrigate crops and make them more vigorous.
5. The water can be used for cooking and washing vegetables.
6. Water can remove dirt on the body and wash clothes.
