Single-Frequency Space Lasers
With the ever-increasing precision of atomic clocks and satellite surveillance resolution, soon we may be able to synchronize and position satellites precisely enough that space-based lasers can be programmed to interfere coherently on a single target (of potentially arbitrary size) from thousands of miles apart.
Using (near-)single frequency lasers, a single target in three-dimensional space can be chosen down to the (milli)meter, or even finer, and hit with coherently interfering radiation. The end result would be a tool that could split (or form) molecules simply by uploading a set of coordinates to a set of science satellites. Thus, a large group of laboratories could put funds into the creation of a satellite network usable by everyone, no matter their location on Earth.
