The captain also realizes that they can move the sphere into the ship by simply rolling it off its pedestal onto a levitator and carrying it, as long as they make no attempt to lift it against the planet's gravity. Once it is in the ship, they can surround it with energy receivers and feed the energy it broadcasts directly into the ship's engine, which should give the ship enough power to move it. Once the scientists on Earth work out the sphere's operating principles, they will be able to duplicate it and use it to power Earth's civilization.
