With a space elevator, the need for rocket fuel is eliminated completely. The elevator draws its initial launch energy from an electrical-power station on the ground. As the vehicle rides farther up the cable it requires less electrical energy, relying more on the centrifugal force produced by the spinning counterweight to pull it into orbit. At these speeds, a vehicle could detach from the cable and fly off into space at speeds fast enough to reach Mars in days or weeks instead of months. Inc. All rights reserved.
