People say that creativity is not all about finding out different solutions every time its some thing about applying the simple solution to the different issue too.
How many times we have used the sun shades or sun protection devices in our life’s may be countless times in form of sunscreen, umbrella, hats.. So this simpler idea was utilized by the scientist” Roger Angles” to use the Sunshades to protect the earth from the harmful uv rays. On hearing this it sounds some thing like of Munna Bhai’s CIRCUIT "ho jayenga bhai" .To give sunshade to the entire earth. The easier it sounds the tougher it is.
Initially Roger planned something like a light-blocking cirrus cloud; the flock of spacecraft would diffuse about two percent of the sun's energy away from the Earth.
So instead of one shade, he devised a plan to launch trillions of disc-like craft, each 2 feet in diameter. Made from a lightweight film, each vehicle would weigh as little as a butterfly.
And this special craft will be launched by using electromagnetic energy instead of fuel, using a mile-high vertical track to fling about a million compactly packed spacecraft into orbit at once. It would take about ten years and a few trillion dollars to get every component into orbit. Hff now it looks some thing tough to do, but this is not the end once there, each flyer would join the cloud. Special crafts with radio beacons that work like Global Positioning satellites would be scattered throughout the cloud, sending position and velocity information to each craft to help it maintain its position facing the sun. Further Tiny, mirror-like sails would harness the pressure created by sunlight to control each craft's position.
the expected lifetime of each craft is around 50 years. Although the sunshade could potentially cool global temperatures and what amount of changes it will bring to the weather systems and water cycle is also an not much predictable issue till now.
But but to for the issue we need to get approval from all the nations existing on the earth. which in itself is a tougher task .
And if the plan gets approved and succeeded then we will be having a tiny black spot on the sun. which might be the beauty spot for the sun to save us from the harmful uv rays.
Isn’t it much easier to reduce our emissions, cut our energy use cover small distances by cycle or walk , become more efficient, reduce waste of energy reduce pollution and develop much more renewable energy.
