Okay, a lot of people say that one of the major things that hold up space travel is the launch. If a new method could be discovered then it probably would help space research immensly. Here's a question. why use chemical propulsion? If a large enough coil gun could be made and enough power provided to it you could at least launch sats a lot cheaper. you might have a 100+ g acceleration but a properly designed sat could take that. A person would go squish but if your coil-gun was longer so it could reach high enough speed without that acceleration why not use that? What do you guys think?
