Boeing Proposes Using Gas Clouds To Bring Down Orbital Debris
cylonlover writes "Boeing has filed a patent application for a method of disposing of dead satellites and other debris orbiting the earth by hitting them with a puff of gas. The method, which is still at the conceptual stage, is designed to slow down satellites, forcing them to re-enter the atmosphere without sending up more space junk that itself will need disposing of. The idea is to send a small satellite into orbit containing a gas generator. This generator can be a tank of cryogenic gas, such as xenon or krypton, or a device designed to vaporize a heavy metal or some relatively heavy elements like fluorine, chlorine, bromine, or iodine. This gas would be released as a cloud in the same orbit as the debris, but traveling in the opposite direction."
Clever of them to patent this, since knock-off space-junk removal systems are in such high demand.
A space fart!
It's an apparently wholly new and unique method for doing something in the physical world. Why would it make them evil to patent that?
Please do correct me if I am wrong, but this reads like a patent application that contains a novel, concrete implementation of an idea that isn't necessarily obvious to one skilled in the art. That is what patents are supposed to protect, and I have to say I have no problem with that.
It's perhaps the first /. post in a long time that contains a patent that respects both the spirit and the letter of what a patent is supposed to be. It also sounds fairly ingenious and very interesting considering the possibilities, so props to Boeing.
