Mercury captured by the "Messenger" spacecraft.
Exploitation of Mercury resources will provide the raw material for humans to carry out the next phase of the project but it is not a solid shell, but "a large number of independent structures densely surrounding the sun, forming a spherical shell" Earth Horizon and the International Space Station solar panels Arrays.
This Dyson ball will adopt the same principle, but the scale will be even greater.
Beijing time April 12 news, this sounds like a sci-fi storyline, but in fact the realization of a huge ball around the sun, use it to collect solar energy dreams closer than we think, of course, we need first Blow up Mercury.
A distinguished technical expert said that in a matter of decades we can begin to build a "dyson sphere" that provides us with more energy than we need. George Defoskey said that by "opening" the entire planet Mercury, asteroids, and even planets like Venus, we can collect enough materials to complete this vast project. The president of the American Institute of Ethics and Renaissance Technology, Defossky, described the bold blue sky plan on the organization's website. He believes that the project will begin in the next 25 to 50 years and the first phase will be completed in a few decades. But it is not a solid shell, but "a large number of independent structures densely surrounding the sun, forming a spherical shell," these components are built in stages. They will form a "receiving surface" around the sun, absorbing the energy generated by the sun, to provide energy for the next phase of the project, so as not to rely on fuel from the Earth.
All this sounds very good, but even the Defus basics admit that there are many obstacles to achieving this dream, apart from never having an astronaut who has ever visited Mercury. Another major issue will be construction issues. He quoted a plan proposed by Oxford University physicist Stuart Armstrong, who broke down the project into five “ten year plansâ€, initially combining the first array. However, Devofsky said: "We will have to extract resources from Mercury. In fact, we are likely to have to decompose the entire planet. Dyson Ball needs a lot of material. In fact, we have to cover the entire Sun, not only to break down Mercury, but also To split Venus, some other out-of-plane planets and any nearby asteroids.†The concept of Dyson Ball was proposed by astronomer Freeman Dyson in 1959. But until now, it has always been a science fiction material, appearing in fiction author Alan Steele's "Hex" and other novels.
Defoski wrote: "The Dyson sphere will provide us with more energy than we have ever known, and will greatly increase our living space. Considering that the planet has begun to reduce resources and we need more energy and living space. It seems to us humans that this is a good long-term plan." However, in his plan he did not explain how to send the energy from the sun to the 93 million miles (150 million kilometers) away from Earth. . Devofsky said: "It seems very clear that Dyson Ball's idea is no longer classified as a science fiction category, or an unattainable dream. Like other adventure projects, such as space elevators or Mars earth, we should put it Place it in a position that is as important as our other recent space exploration and work programs and seriously consider it."
