Mirrors In Space To Fight Global Warming

Mirrors In Space To Fight Global Warming

As global warming raises serious concerns about the future of the world. The scientists have come up with an unique method to fight the global warming.

The method includes firing trillions of mirrors in to the space to deflect the sun's rays forming a 100,000 square mile 'sun shade'. As told by astronomer Dr Roger Angel, at the University of Arizona, the mirrors would have to be fired one million miles above the earth using a huge cannon with a barrel of 0.6 miles across.

The gun is 100 times more powerful than the conventional weapons and need an exclusion zone of several miles before being fired. The coast of the entire execution will amount to 350 trillion dollars, this is one of the other major setbacks faced by the project. However, Dr. Angel is confident about the success of the project.

"What we have developed is certainly effective and a method guaranteed to work," he said. "Tests are ongoing but we expect to be ready to launch within 20 or 30 years time. Things that take a few decades are not that futuristic," he added.

Dr Angel has already secured NASA funding for a pilot project and British inventor Tod Todeschini was commissioned to build a scaled-down version of the gun.

A four meter long cannon has been constructed at the workshop of Dr. Angel located at Sandlake, Oxfordshire, for a TV documentary investigating the sun shield theory.

"I knew I could put it together safely but at the end of it all I didn''t know what I was going to get," said Todeschini. "It was immensely dangerous. I was attempting to build a gun to produce 1,500G of force but it ended up creating about 10,000G and we had to turn the power down," he added.

According to Todeschini, "Most weapons used by the army produce 100Gs of force so our gun was about 100 times more powerful."

"We've proved it''s possible to build a scaled-down version of the gun needed to get these lenses into the air so it''s just a matter of scaling up the designs for the real thing," he said.

If the 'sun shield' experiment is a success, Dr. Angel says that the mirrors will last for 50 years before having to be replaced. "What you are talking about is a project which will stop global warming for centuries to come," he said.

"At the moment, the sums involved sound huge but in the greater scheme of things it's a price worth paying," he added. "Over 50 years, the mirrors will become damaged and therefore fresh lenses will need to be fired into space to ensure the shield is constant," he further added.
