Elevators to Space :: physics space elevator

The idea of an elevator into space is not a overbold one. First contemplated by a Russian scientist in 1895,it was not genuinely popularized until Arthur C. Clarkes novel Fountains of Paradise in 1978.The idea is so simple, it seems absurd. A tether is extended from the surface of the earth, and using acombination of sedateness and centrifugal force, is extended outwards. Vehicles lowlife then scale this tether,removing the need for costly rockets.Arthur C. Clarke claims that the space elevator is an attainable goal, and we will have one virtually 10 yearsafter people stop laughing. However, before it can be constructed, on that point are many engineering issues thatneed to be worked out. This page is not the end all, and contains no breakthroughs or answers. However,it does include round interesting information that may aid in answering questions astir(predicate) this subjectIf youre going to prepare a 62,000 km rope, what would you use?. This diligence ends up beinga gig antic tug of war. With gravity displace down, and centrifugal force pulling up, the real has to bevery infrangible just to hold its own weight, let alone the additional preventive of the elevators car. Until theearly 1990s, no such material was known. In 1991, carbon nanotubes were discovered. Although notcurrently a feasible option, current look for in this topic may lead to breakthroughs very soon.How do you build a vehicle capable of climbing a tether into space, down the stairs its own power? This leads to anotherengineering feat for this exteriorize is a climber. It may seem interchangeable this is a simple extension of modernisticrobotics, many of the caveats of this application require further research and experimentation.With any gigantic structure, a major question on everyones mind is is it safe? For something like a severalthousand kilometer high freestanding elevator, there are two questions is it safe for the occupants/cargo?and is it safe for everyone/everyth ing else?The last question, and perhaps the most important of all How much is this going to cost? If its noteconomically feasible, all of the research in the world will not make it happen. No matter how you look at it,a project like this will be a very expensive endeavor. wizard of the biggest obstacles to building a space elevator has always been the choice of material for thetether. Until recently, there was no material known to man that could handle the stresses involved. Withthe baring of carbon nanotubes, the strongest material known to man, a possible solution has been found.
