Space Technology for Reduction of Desert Areas on Earth and Weather Control

Journal Title: INCAS BULLETIN - Year 2018, Vol 10, Issue 1

Abstract

In precedent papers the authors presented the idea of a space system composed of two opposite parabolic mirrors (large and small) having the same focal point. This system is able to concentrate solar power in a strong light beam having irradiance of hundreds or thousands of times stronger than the solar irradiance on Earth's orbit. The system can be placed on a Sun synchronous orbit around the Earth or on the Earth’s orbit around the Sun at a distance of several hundred km from ground. When the concentrated light beam is directed toward the Earth surface it can locally melt, vaporize or decomposes tones of ground in its elements. This is happening because when the ground is hit by the light beam, ground temperature can reach thousands of degrees Celsius. At such temperatures the matter is decomposed into constitutive elements. For example, the silicate oxides which are frequently found in the composition of desert ground are decomposed into oxygen and silicon. Similarly, other oxides release oxygen and other type of oxides or constitutive elements. A network of deep and large channels can be dug in this way in hot deserts as Sahara. When these channels are connected with the seas & oceans, a network of water channels is created in those deserts. In this way, the local climate of deserts will change because channel water is vaporized during daytime when air temperature reaches 50ºC and condenses during nighttime when air temperature is around 0ºC. Presence of clouds over the hot deserts can lead to a reduction of ground temperature and rain follows. The channel water can be desalinized for producing drinking water and for irrigation using simple equipment. In addition to these advantages, channel deserts can be a solution for melting of polar ice calottes and flooding of seaside areas that are inhabited areas. On the other hand, the system composed of two opposite mirrors can be used for strength decreasing or deviation of hurricanes and tornados. The power of these meteorological phenomena increased in the last time due to global warming producing disasters of tens of billions of dollars. The hurricane is a thermal engine working in Carnot cycle. Due to this fact, although the difference between the cold source temperature (temperature of high atmosphere) and hot source temperature (temperature of ocean surface) is of only 100 °C, the thermal efficiency is ηt=0.333 leading to increasing of hurricane's total energy at extremely high levels. The cold source can be heated through vaporizing the system of clouds of hurricane formed in the high atmosphere by the concentrated light beam directed from space. In this way the energy of hurricane or tornado no longer increases and damages produced at ground level are limited. Another possibility is to vaporize locally the hurricane's eye-wall for its deviation far away of dense populated areas.
