Space elevator is theoretical tether reaching geostationary orbit, lowering launch costs to space by avoiding rockets.
Trinn-for-trinn guide
- 1Input Earth parameters, cable material properties (strength/density)
- 2Calculate tension distribution along cable
- 3Verify feasibility
Løste eksempler
Inndata
Carbon nanotube cable (theoretical)
Resultat
Height ~36,000 km, tension manageable with current materials marginally
Material science limitation
Vanlige feil å unngå
- ✕Neglecting material weight effect
- ✕Ignoring atmospheric drag at lower altitudes
Ofte stilte spørsmål
Why hasn't anyone built one?
No material simultaneously strong enough and light enough; requires ~100× current material performance.
