NASA will fund the development of satellites transmitting solar energy to Earth


The company Artemis Innovation Management Solutions announced that material resources are allocated to the initial development of certain projects proposed last summer by NASA. The construction of the satellite, which will be able to collect solar energy, directing our planet special beam of energy that scientists hope to "connect" to the electric grid of the Earth is also included in the list of projects. On the construction of such a satellite debated for several decades, many researchers and scientists, but until now, no one could develop a design that is capable of continuous operation in space. Now, however, the idea proposed by the famous NASA engineer John Mankins, now a staff member Artemis, aroused great interest of NASA, which has agreed to provide all the necessary tools for a detailed study of the idea.

Mankins idea is based on the imitation of biological plants and how they use the sun’s energy. Generally speaking, takes a flower, no matter what, which uses its petals to collect the necessary energy to it. Mankins says his idea is to build a set of petals of many small mirrors that would direct sunlight to special solar cells. The energy generated by solar panels is converted into microwaves aimed at the receiving station on Earth, where the microwaves will be produced from a number of energy (possibly tens of thousands of megawatts). To make the project feasible, mirrors and solar panels should be small and light, so they can be easily transported into space, using existing vehicles. And because the project will consist of the components, the construction cost will be much lower than other proposed ideas.

The project, called solar power satellites using Arbitrarily Large PHased Array (arbitrary large set of phased - supersonic wave alpha) would use thin layers of mirrors, thereby decreasing the overall weight. Such mirrors are curved in a special way to use the maximum amount of sunlight, which receives satellite. In addition, the satellite will be located at a considerable distance from our planet that would not fall into its shadow, and thus ensure the smooth flow of microwave energy to the Earth.

Pre-funding is directed to a certain amount of evidence of the practical implementation of such an idea and investigating the possible obstacles for the realization of the project to life. If NASA likes what she sees, the next step will probably be the construction of a stripped-down, cheaper version of the project, which will have to operate in low Earth orbit. If this stage of the project will take place as planned, the satellite will be built already in full size and, in consequence, in orbit and transported to the calculated point in space, to ensure a continuous flow of energy.

Such a project may be the decision that has been looking very many researchers and scholars, and will be able to improve on the existing situation today for energy production in the world.
