Chinese Scientists Get Ready to Build a Space Elevator

摘要

Chinese scientists at Tsinghua University have patented a carbon nanotube fibre they say is strong enough to build a space elevator. They say the fibre will be in great demand in many high-end fields such as sports equipment, ballistic armour and aeronautics - and would be perfect for space elevators.Is a lift that could travel from the Earth into space actually possible, or is it just the stuff of science fiction? Although generations of research have made the rocket the most reliable form of propulsion ever invented, space vehicles are still grossly inefficient.
