Large, massive structures could be built in space simply by using radio waves that create force fields to move materials and assemble them into various structures. Once bonded in place, the structures could lay the groundwork for human settlement in space and a space-based economy, according to Narayanan Komerath, an aerospace engineer at Georgia Tech.



A large number of objects can be arranged into shapes to form structures in reduced-gravity environments using radio and electromagnetic waves, according to Komerath, who is a professor in Georgia Tech’s School of Aerospace Engineering. The structures could range from micrometer-scale discs to kilometer-scale habitats. More here.
