Utopian inventions by Anthony Ratkov, including domed cities designed to reduce global warming, floating cities made of ice, and pyramids that produce water for arid regions.
It is often said that the temperature of the earth is increasing, and this increase in temperature is caused by human industrial activities. Human beings have built factories and power plants that expel heat into the Earth's atmosphere, and they have also created cars and trucks that expel heat into the atmosphere. One way to reduce the amount of heat that goes into the atmosphere is to build domes over factories , power plants, and eventually, over entire cities and towns. These domes would be called thermal isolation domes, or thermal insulation domes.
First you would build domes to cover up nuclear power plants, coal-burning power plants, and so on, so the heat produced by these facilities will not escape into the atmosphere. If any factory produced a significant amount of heat as a by-product of it's industrial process, you would build a dome over that factory. The government may make laws that require all the factories and power plants to have domes built over them.
The interiors of the domes would have to be air-conditioned and properly ventilated so the people who live and work inside these domes are comfortable. Any exhaust smoke produced by equipment inside must pass though an array of scrubbers and coolers before it escapes into the atmosphere. If you built a dome over every city and town on Earth, global warming would be virtually eliminated.
The illustrations above show what the domes would look like. The domes that are built over cities and towns would be connected by tunnels. Electric cars and other electric vehicles could travel through these tunnels, and the heat produced by these vehicles will not escape into the atmosphere, where it would contribute to global warming. As global warming causes temperatures to rise, tropical diseases such as malaria that were formerly found only in the steamy climates of tropical countries may spread as far north as Canada and Alaska. Malaria is carried by mosquitoes, but the people who live in the domed cities will breathe pure, filtered air, it would be impossible for mosquitoes to get into the domes to spread disease.
Pyramids For Irrigation.
If you have ever looked at a very high mountain, you can see that there is always snow at the top of the mountain. That is because the Earth's atmosphere is warmest near sea level, and the temperature gets progressively colder as you go higher. The air is so cold at the top of a high mountain that the snow and ice there never melts. If water is needed in a hot, dry desert, you could build a pyramid in that desert. The pyramid would be approximately three miles high. After you build it, snow and ice will accumulate at the top of the pyramid. Some of the snow and ice will occasionally fall off, and it will slide down to the bottom of the pyramid. When it gets to the bottom, it will melt, and will turn into water. This water can be directed through a series of canals to irrigate fields so crops can be grown.
The computer-graphic illustrations above show pyramids designed for irrigation.
The picture above shows a natural mountain and an artificial pyramid, for height comparison. Notice that the mountain has ice at the top and the pyramid also has ice at the top.
A floating city that floats in the Earth's atmosphere can be made of ice. The city would be located in a hollow sphere made of ice. The ice sphere would be filled with a lighter-than-air gas, such as helium or hydrogen, to keep it aloft. The bottom of the city would be insulated to prevent heat produced within the city from melting the bottom of the ice sphere. If the lighter-than-air gas that supports the city is hydrogen, unmanned drones may fly around inside the sphere, using anti-static equipment to dissipate static charges. A charge of static electricity could ignite the hydrogen and cause it to explode, so anti-static drones would have to fly around inside the sphere 24 hours a day. Helium isn't explosive like hydrogen, but since hydrogen would be cheaper than helium, hydrogen would probably be used to keep the sphere afloat. A plastic sheet over the houses and buildings in the city would protect the people who live there from coming into contact with hydrogen, so they do not breathe the hydrogen gas.
The computer-graphic illustrations above show floating cities, located inside of hollow spheres of ice.
The illustration above shows an ice city floating near a mountain. The snow at the top of the mountain will never melt, since it is always cold at the top of the mountain. If the city always floats at the same height, the ice shell of the city will never melt, either, since the air is always cold at that altitude.
