Physicists Have Created A Tractor Beam!
Tractor beam created: the ‘holy grail for laser physicists’

First long-distance optical tractor beam can repel and attract objects and could be used in controlling atmospheric pollution

Laser physicists have built a reversible tractor beam and are using it to retrieve tiny particles. It has nowhere near the pulling power of tractor beams envisaged in science fiction, but the first long-distance optical tractor beam has so far moved particles one fifth of a millimetre in diameter a distance of up to 20cm.

Tractor beams were thought to be science fiction and until recently, have only been seen to work at the microscopic level:

They COULD use it to clean up the atmosphere, but they won't.

"The world will soon wake up to the reality that everyone is broke and can collect nothing from the bankrupt, who are owed unlimited amounts by the insolvent, who are attempting to make late payments on a bank holiday in the wrong country, with an unacceptable currency, against defaulted collateral, of which nobody is sure who holds title."

Never attribute to malice that which is adequately explained by stupidity.

That's awesome!

As the article points out, so far they have managed to create tiny tractor beams that can work at microscopic levels - but it seems this acoustic version can work on larger objects than this new laser version when they mention centimeter-sized objects as opposed to this laser's one fifth of a millimeter-sized objects. Perhaps a combination of the two could realize Wesley's science project from Star Trek TNG.

Maybe they can start aiming them up into low orbit and start pushing some of the junk out of orbit? Since everything there weighs just about nothing, shouldn't be too hard to do. Or they should pull some of it down, let it burn up on decent...

Maybe they're doing that already, as maybe that explains the Russian heavy Meteor that crashed about 1 to 2 years ago in a populated city spot in Russia. I believe it was called Chelyabinsk. Boy!, that was fun watching it clubber the Ruskies and Commi's over there.
