Rockets are actually relatively gentle in comparison, generally <3G for humans. This is because you can apply constant thrust the entire way to orbit (>~400 km on Earth) With a Mass Driver, you can only apply acceleration for however long your driver is, so you have to get up to speed in a much shorter distance. If you build a 4km driver (length of Heathrow Runway), you have to get up to speed in 1/100th the distance causing drastically higher accelerations. (note, some poor assumptions here because horizontal distance =/= vertical distance, but the general idea is correct). |
