DESERT-VISION - the name says it all

36 Billion km 2 of desert are waiting to be brought back to life. The deserts of this world are bigger than Africa, 2 times the size of Russia and 5 times the size of Australia! What potential there is in reviving these huge land masses! Some may dream of terraforming Mars, but shouldn't we invest all our energy, passion and financial resources in preserving our magnificent home planet - it's a worthwhile task! How is it possible to make the deserts bloom again? To make this possible, we need the multifunctional Thermo-Solar Power Plants of DESERT-VISION, a division of SOTA-DOMUS SWISS.

The DESERT-VISION Thermo-Solar power plants have some very remarkable features. DESERT-VISION Thermo-Solar power plants are so-called base-load power plants, which means they reliably generate electricity around the clock (24 hours), 7 days a week. More technical details about the power plants can be found here. As you can see in the video, these thermo-solar power plants capture the enormous solar radiation in the desert with simple linear mirrors. These mirrors form a roof, which ensures that a cool half-shadow is created under the mirror surface. The huge area under the solar mirrors can be used for a wide variety of tasks. DESERT-VISION Thermo-Solar Power Plants are arbitrarily scalable. In order to have a simple, manageable calculation size, we assume a thermo-solar power plant size of 1 GW - 1 power plant module. 1 GW corresponds to the size of a medium-sized nuclear power plant. The DESERT-VISION power plant module has an area of approximately 4 x 4km - 16km2 or an area of 16 million m 2 or 2.222 football fields. What can this DESERT-VISION power-plant-module do? • It generates 1GW of CO2-free electricity - 6,000 GWh of CO2-free electricity when operated for 6,000 hours a year. • The waste heat is used to produce fresh water from sea water. Therefore, the power plants have to be built near the sea. 150 million m 3 of drinking water are produced annually by a DESERT-VISION power plant module. • Under the solar mirrors is an area of 16 km 2 in the cool half-shadow. Since the height under the mirrors can be adapted to the use, theoretically, high-rise buildings could also be built underneath - entire cities. • We assume an overall height of 20 m. This means that we have a clear width of 20 m under the mirrors. This means we have a clear width of 20 m under the mirrors. • Here are some possible uses: o Use as a glass house for growing fruit and vegetables.With 10% of the produced fresh water, one could produce ~112,000 tons of fruit and vegetables annually under the solar mirrors. o It is also a good idea to locate food processing here, as electricity and water are reliably available in large quantities at favourable prices. o Server farms, which have a gigantic electricity demand, could be located under the land. o Other electricity- and water-guzzling industries could be located here, because nowhere else do they have such favourable conditions, which could be fixed for a very long period of time. ▪ Steel production ▪ Aluminium production ▪ Cement production ▪ Glass production ▪ and much more o One of our special concerns is to build small towns under the solar fields, in which the rapidly increasing number of climate refugees can find a new home. Of course, the use under the solar mirror fields could be continued at will. The huge quantities of drinking water are used to 80% for the construction of our PRE-FUEL plantations. With the fresh water quantity of 130 million m 3 we could run a plantation of 130km 2 (11.5km x 11.5km). • This plantation would grow 1.7 million trees. • It would produce 3,070m 3 of PRE-FUEL. • A good 6,000 cars could run on this for a year. • The PRE-FUEL plus CARBON-CAPTURE Technique would permanently absorb 15,340 tonnes of CO2 from the air every year.

After knowing the performance of a DESERT-VISION power plant module, we would like to look at what 40 modules will achieve. This description is intended to show the enormous potential beyond the production of PRE-FUEL will be shown.

Example project - Europe / Africa: The squares shown on the map correspond to 10 DESERT-VISION modules with the corresponding plantations. The sizes of the squares are not to scale but clearly larger, because otherwise they could not be seen. 10 DESERT-VISION Thermo-Solar modules each are combined with plantations. are HVDC (high-voltage direct-current) lines with a capacity of 8 GW each power. These lines are capable of transmitting up to 10 GW of power, with very low losses > 10% over 3,000 km. These lines have a diameter of only about 25 cm. As they are direct current lines, there are no magnetic fields. These lines can be laid in water and in the ground without any problems. are HVDC lines with 2 GW each for distribution in Africa. ist an HVDC line with 10 GW also for distribution Africa

With the power lines to Europe, the European grid could be supplied and stabilised with 24 GW of CO2-free base-load energy. At the moment, the European interconnected grid is in a very critical situation because the highly fluctuating renewable energy sources are increasing more and more and the base load energy is decreasing more and more. On several occasions, the European interconnected system has been on the verge of collapse. Should this happen, Europe could be without electricity for several weeks - that would be absolutely catastrophic for an industrial society. With the increasing shutdown of base-load power plants and the expansion of renewable energy sources, the problems are getting bigger all the time. The reinforcement of 24 GW of CO2-neutral base-load energy would provide significant relief, as this corresponds to the output of 24 nuclear power plants. Sollte das nicht ausreichen könnte die Leistung nahzu beliebig ausgebaut werden. With the HVDC power lines to Africa, the continent could start its industrialisation. Without energy, sustainable industrial development is impossible. With the 12 GW of CO2-neutral electricity shown here, a clear first step would be taken. This capacity could also be expanded at will, as there are enough locations for the construction and operation of DESERT-VISION power plants. For Africa in particular, the enormous production of drinking water and food that goes hand in hand with the construction of DESERT-VISION power plants is of vital importance.

Summary: • The 40 DESERT-VISION Thermo-Solar modules produce ~40 GW of CO2 free baseload electricity. • If the areas under the mirrors were used exclusively for food production, one would be able to produce ~ 4.5 million tons of additional fruit and vegetables. • If a 10-module system were used to build a city in the desert, the usable area under the mirrors would be 160 km 2 , providing space for many thousands of people and large industrial settlements. • The 40 PRE-FUEL plantations could produce ~ 123,000 m 3 of PRE-FUEL. This could power ~ 123,000 cars for a year.The ~ PRE-FUEL plus CARBON-CAPTURE Technique would absorb and permanently store more than 613 thousand tonnes of CO2 from the air. • The 40 DESERT-VISION power plant modules would generate6 billion m 3 of drinking water annually from their waste energy. To get a rough idea of this huge amount, let's convert this to tanker trucks with 40m 3 tanks - 150,000,000 tanker trucks every year.

This model view of a region could be applied to many regions of the world. The driest continent in the world - Australia - alone could be transformed into a paradise and huge amounts of CO2-free energy, food and much more would be produced. This brief consideration already impressively shows what is possible today with the multifunctional DESERT-VISION Thermo-Solar Power Plants.
