Japan group has more than 100 engineers trying to design a space elevator . Carbon nanotube would be used as a wire to lift the elevator into space . Indeed , if successfully built , the space elevator would be an unprecedented feat of human engineering . Comment: Group sets the 2030s as a target to begin construction , although it could be later .
