magnetic launcher

shared by Juxi Leitner on 17 Sep 09 - No Cached
  • The launcher operates 350 days and launches 100 kg payload every 30 min (This means about 5000kg/day and 1750 tons/year). Then additional cost from installation is $2.86/kg then total cost is $6/kg
  • The railgun does not have this limit, but produces some engineering problems such as the required short (pulsed) gigantic surge of electric power, sliding contacts for some millions of amperes current, storage of energy, etc.
  • A short rail way (412 m) would launch 7500 Gs into orbit.

    The definitive comparison. It is clear that Joris is using an inefficient programming language.
