ISS Could Be Fitted With Lasers To Shoot Down Space Junk

An anonymous reader writes Japan's Riken research institute has suggested a new idea for dealing with space junk. They say a fiber optic laser mounted onto the International Space Station could blast debris out of the sky. From the article: "To combat the increasingly dense layer of dead satellites and miscellaneous space debris that are enshrouding our planet, no idea — nets, lassos, even ballistic gas clouds — seems too far-fetched to avoid. Now, an international team of researchers led by Japan's Riken research institute has put forward what may be the most ambitious plan to date. They propose blasting an estimated 3,000 tons of space junk out of orbit with a fiber optic laser mounted on the International Space Station."

Revising a previous concept

The idea of using lasers to de-orbit space debris has been around for a while.

Back when I was working on lasers for power beaming, the idea was discussed as an alternate use for the ground-based lasers.

See, that's the mistake supervillains make... You need to start small. Start with a wealthy but small place, like Martha's Vineyard, so that the powerful know that this is coming for them, so that they can put pressure on their private government officials to make it happen. Then move on to bigger and bigger wealthy suburbs and cities until you get to Washington.

After all, if you destroy DC, you destroy the people that are authorized to pay you in the first place.

One flaw

Ok, this is a nice plan and all, but there is one little problem: how do you keep the sharks alive in a vacuum?
