Researchers at the Georgia Institute of technology are working on methods for assembing arbitrary structures in space using only debris and electromagnetic waves:
But the heavy lifting would be left to radio waves. Given a few months to do the job, Komerath says they should be able to assemble rocks, brick-sized or bigger, into any given shape. Later in October he will discuss his idea at a conference in Atlanta for NASA’s Institute of Advanced Concepts – a think tank of the 88-member Universities Space Research Association.
If only my apartment was an airless vacuum, I could program my radio transmitters to pick up my dirty clothes and dishes, shoot the dust off of my furniture, and pull the dirt off of my carpet.
