  1. Space elevators would be made up of:

    • a carbon nanotubes composite ribbon forming a track for the elevator
    • a robotic lifter, which would travel up and down the ribbon at 118 miles per hour (190 km/h)
    • a mobile anchor station, which would probably be in the equatorial Pacific
    • a heavy counterweight in space, at the top of the tether; scientists might use recycled materials to build the counterweight
    • a free electron laser station located on or near the anchor station; the laser would beam 2.4 megawatts of energy to photovoltaic cells attached to the lifter, powering conventional niobium-magnet electric motors
