Currently, much attention is paid to the use of alternative sources of all kinds of resources.For example, mankind has long been engaged in development of energy from renewable substances and materials, such as heat the planet's core, tides, sunlight and so on.The following article will address climate and space resources of the world.Their main advantage is that they are renewable.Hence, their repeated use is sufficiently effective, and stocks can be considered limitless.
first category
Under the climatic resources traditionally understood solar, wind and so on.This term defines the inexhaustible variety of natural sources.And its name got such a category as a result of the resources that are included in its composition, characterized by certain features of the climate in the region.In addition, this group also secrete a subcategory.It is called agro-climatic resources.The main determining factors affecting the possibility of such sources are air, heat, moisture, light and other nutrients.
space resources
In turn, the second of the categories presented before combines inexhaustible sources that are outside of our planet.Among these include the energy of the sun is known to all.Her and take a closer look.
ways to use
to describe the beginning of the main directions of development of solar energy as a component of the "Space resources of the world."Currently identified two basic ideas.The first is to launch into orbit a special satellite, equipped with a large number of solar panels.By striking the photocells their surface the light is converted into electrical energy, and then transmitted to the station-specific receivers on Earth.The second idea is based on a similar principle.The difference lies in the fact that space resources will be collected by the solar panels that will be installed at the equator of the Earth's natural satellite.In this case, the system will generate the so-called "moon zone".
Energy Transfer
course, space natural resources, as well as any others deemed ineffective without a corresponding development of the industry.And this requires effective development, which is impossible without high-quality transportation.Consequently, considerable attention should be paid to methods of energy transfer from the solar cells on Earth.Currently, it developed two main ways: via radio waves and light beam.However, at this stage, there is a problem.The wireless transfer of energy to the Earth must securely deliver resource space.The device, which in turn will carry out such acts, should not have a damaging effect on the environment and the organisms that live in it.Unfortunately, the transmission of electrical energy transformed in a frequency band capable of ionizing the atoms of the material.Thus, the drawback of the system lies in the fact that space resources can be transferred only to a rather limited number of frequencies.
Pros and cons
Like any other technology, we presented earlier has its own particular advantages and disadvantages.The advantages include the fact that space resources beyond the near-Earth space will be significantly greater access to use.For example, solar energy.On the surface of the planet gets only 20-30% of the total light emitted by our star.At the same time, a photocell which is located in orbit, more than 90%.In addition, among the advantages possessed by space resources of the world, can be used to allocate the durability of structures.This circumstance is possible due to the fact that the outside world no atmosphere nor destructive impact effect of oxygen and of other elements.Nevertheless, the space resources of the Earth have a significant number of shortcomings.One of the first is the high cost of installations for the production and transportation.The second may be considered remote and operational complexity.In addition, the need is also a significant number of trained personnel.A third drawback of such systems can be considered as a significant loss in energy transfer from the space station to Earth.According to specialists this specific transport will take up 50 percent of the total electricity generated.
Important features
As mentioned earlier, the technology in question has some distinctive characteristics.However, they determine the ready availability of space power.Here are the most important ones.First of all it should be noted the problems of finding a satellite station in the same place.As with all other laws of nature, there will usually work action and reaction.Therefore, on the one hand it will affect the flow pressure of solar radiation, and on the other - the electromagnetic radiation of the planet.Set initial satellite position will have to support the climate and space resources.Communication between the station and the receivers on the surface of the planet must be maintained at a high level and provide the required degree of safety and accuracy.This is the second feature, which is characterized by the use of space resources.The third is traditionally attributed efficient performance of solar cells and electronic components even in difficult conditions, such as at high temperatures.The fourth feature which currently does not allow accessibility technologies described above, is sufficiently high value as rockets and space power directly themselves.
Other possibilities
Due to the fact that the resources that are currently available in the world, most of whom are non-renewable, and their consumption of humanity over time, in contrast, increases with the approach of the moment of the complete disappearance of the most important resourcespeople are increasingly thinking about the use of alternative energy sources.In particular they include and space inventories of substances and materials.However, apart from the possibility of an effective production of solar energy and other treats humanity no less interesting possibilities.For example, the mining of valuable substances for earthlings can be carried out on the bodies of space located in our solar system.Let us consider some of them in detail.
Moon
Flights to it for a long time ceased to be aspects of science fiction.Currently, the satellite of our planet plow research probes.It is thanks to them that humanity learned that the lunar surface has a composition similar to the Earth's crust.Consequently, there can be mining of valuable substances such as titanium and helium.
Mars
the so-called "red" planet also a lot of interesting things.According to studies, the crust of Mars is much more rich in pure metal ores.Thus, it may begin in the future development of copper, tin, nickel, lead, iron, cobalt and other valuable substances.In addition, it is possible, it will be deemed to Mars main supplier of rare metal ores.For example, such as ruthenium, scandium or thorium.
giant planets
even distant neighbors of our planet can provide us with many essential for the normal existence and further development of human substances.Thus, the colonies on the outer reaches of our solar system will deliver to Earth valuable chemical feedstock.
Asteroids
Now scientists have decided that it is above the cosmic body, furrowing the space of the universe, may be the most important stations to provide a variety of necessary resources.For example, some asteroids using specialized equipment and careful analysis of the data have been found valuable metals such as rubidium and iridium, as well as iron.Among other things, the above cosmic bodies are different suppliers of complex compound, which is known as deuterium.Subsequently, it is planned to use this substance as a main raw fuel for power plants of the future.We should also mention another vital issue.Currently, a certain percentage of the world population suffers from constant water shortages.In the future, this problem could spread to most parts of the world.In such a case, it may be asteroids providers such vital resource.Because many of them contained fresh water as ice.
