The proposed concept describes the construction processes in space of various structures that can control the energy of our star. They want to start with the simplest thing – to cover the Earth a little bit with a giant barrier from the sun.

The ultimate goal is called prevent global warming on the planet. With decarbonization policies failing effectively, people have so far failed to agree on a global scale to introduce new technologies, and rising energy prices have forced many to switch back to burning coal, researchers want to go the other way.

• They propose to make enormous clusters of bubbles between the Earth and the Sun and place them in space.
• They can be made of the thinnest film, and since there is no external pressure in space, very little gas is required to inflate such structures.
• The vulnerability to meteorites is offset by the large number of bubbles and the ability to quickly deliver them into orbit any number of times to repair holes in the barrier.
• It is not necessary to make the bubbles opaque, it is enough that they retain at least some solar energy.
• The mathematical model showed that If you reject just 1.9 percent of solar radiation, it will cool the planet and even reverse warming..
• The authors of the concept clarify that it is not a climate management tool, but a temporary emergency measure to address current problems.

This is not the first such development and probably not the last. In addition, scientists are working to reduce the effect of carbon dioxide on the atmosphere to reduce the greenhouse effect. Japan, for example, has developed a new compound that captures carbon dioxide while showing 99 percent efficiency. It’s also the world’s fastest system – at least twice as good as its peers. Also, the technology is reusable.
