We already started discussing Kardashev Scale in my previous video.
We talked about what Kardashev Scale is and Type I alien civilization. Following video will talk about rest of the levels in that scale.
A Type II civilization capable of harnessing all the energy from the star in their solar system. And Type IIIcivilizations, a state we can reach several million years, knows how to capture and focus the energy of entire galaxies.
We humans are obviously not the type I, II or III yet. First we need to start with baby steps – by ending the plundering of our planet to use their remaining resources. And then we will try to stop our way into more upscale type II neighborhood by capturing and channeling the enormous energy of our sun. This may be feasible in the next few thousand years, if we survive that long.
In 1937 the book, “Star Maker” written by Olaf Stapledon was perhaps the first person to think of a “light trap” to break the sun’s energy. He wrote about energy capture systems so enormous that they actually dimmed the light of the galaxies.
This story is what sparked the mind Freeman Dyson, a mathematician and theoretical physicist. He began to ponder how possible or impossible it may be to capture all the star power for human use.
The sun provides an incredible amount of energy. But because of its distance and direction, most do not reach our planet. If we can build mega structure around the Sun as a sphere would be a much more effective way to get caught the sun’s crazy juice. The Sphere will help to catch every beam of energy from the sun. That way you would have 550 million times more surface area than the entire planet, all catching rays to return to Mother Earth in the form of raw power.
There is also the extreme difficulty of finding enough raw materials to build a solid shell. Such a feat would probably require more material than we could find in the entire solar system.
Even if we could find enough solid material to build a solid sphere enclosing the entire sun, the strength of this gigantic solar ball must be enormous. Otherwise, the sphere would just break into countless pieces. In other words, it would be another spectacular failure.
Freeman Dyson admitted sometimes, it would be impossible for us to build a solid sphere around a star. He suggested instead a concept where we released many independent machines to go around the sun, collect energy and beaming it to Earth.
The satellites may be arranged in neat rings. Or they can zoom in different orbits around like a swarm of bees collecting pollen power. Some may be habitable, or they can be used only for energy collection.
There is a third configuration that can make up a Dyson Sphere.In this case, a number of solar sails revolve around the sun. These sails would create a loose bubble around the sun, held in place thanks to a balance between gravity and radiation pressure from the star within.
These satellites could actually be called statites (derived from the words satellite and static) as they would hover in one place instead of moving in orbit. As with the ring or swarm concept would statites absorb outgoing solar energy and then redirect it to the earth for our use.
Regardless of the final drawing, one Dyson ring, sphere, bubble or swarm will require material resources and energy on an unprecedented scale. We will not find enough raw materials for this project on earth. So some speculative types have proposed an alternative – to harvest material from other planets, such as Mercury.
Mercury is loaded with useful materials (such as iron) and it is the closest planet to the sun, so it is wise to start there. When Mercury is removed and the first Dyson rings installed, the project momentum and speed, collecting more and more energy, fueling the production of bigger and better solar panels. And of course all of this energy could be used for other purposes, such as supercomputers (on a scale never before seen), faster space travel technology and countless other ideas we have not even thought.
We would not have to do all this with painstaking work. Robots could do the work for mining and the installation of new solar panels. And the number of robots would constantly increasing (thanks to self-replicating ability) as the scope of the project grew until they became an army of machines crushing planets and asteroids to produce Evermore energy collectors.
