There is a lot of published raw science on Electromagnetic Linear Motors, with several feasibility studies on Earth to Orbit and Earth to Moon systems. There are several challenges with building on that large, such as building large capacitors, building a structure big enough, and dealing with something that high energy. However, I think we are at a critical point where this might become something we understand how to build. We use the fundamental technology everyday in high speed rail, and we've learned a lot from constructing projects like the LHC and Hyperloop. The Navy is planning on implemented these motors for launch assist on the next generation of aircraft carriers.
