# Space Elevator

Cable-based transportation system connecting Earth's surface to geostationary orbit
- Technology Readiness Level: 2/9
- Impact: 5/5
- Investment: 3/5
Space elevators would use a tether extending to geostationary orbit for non-rocket spacelaunch. Research; significant materials and engineering challenges. Applications: orbital ring, sky hook, space fountain. No material yet strong enough; long-term vision.
