Here's some lovely maths on the subject: [link to www.zadar.net] "Under the term the cable length we consider the length where the cable is of the same thickness on the both ends. Consequently, the cable length is 143 800 km (although it can be in reality shorter or longer)."

If a "space Elevator" existed there would be a decent sized mass in geosynchronous orbit around the equator of earth. Armchair astronomers would have seen that through a low powered telescope, perhaps even through binoculars and attention would have been called to it to where the more serious amateur astronomers with larger optical devices would have focused their attention on it and would have made out the 'cable'. Currently the only material we have that could, possibly, be strong enough to make a space elevator is the 'Bucky ball' carbon atom called a fullerene. Fullerenes are a 'new' material that is adaptive nanotechnology. We are only now entering the area of practical application of nanotechnology. While we have had success in creating small fullerenes in the lab, we have yet to mass produce or make a fullerene that is useful in any practical technology. Do not be disheartened by this, during the next couple three decades do expect there to be an explosion of fullerene technology being used in lots of stuff. The glass company Corning invented a 'new' glass back in the 1930's-40's that has had no use until very recently. The 'rediscovery' of it (basically someone was sifting through old files) has lead to new experimentation to see if it can be used to make ultra-ultra thin screens/monitors for cell phones, TV's computers. The strength of the glass is such that a 1/4 inch frame less TV monitor may be on the shelf in the next 10 years. I mention this to point out that we humans do in fact return to old ideas and old 'finds' in order to apply to current (yet new) technologies. It is highly probable that a space elevator will be on the list of applications once mass production of the fullerene stars.

BRIEF AND TO THE POINT User ID: 381742 United States 12/30/2010 10:53 AM Report Abusive Post Report Copyright Violation | no they do not exist. Quoting: Anonymous Coward 346859They do in theory... Poor people do poor people things, and rich people do rich people things. You cannot legislate the poor into prosperity by legislating the wealthy out of prosperity. What one person receives without working for, another person must work for without receiving. The government cannot give to anybody anything that the government does not first take from somebody else. When half of the people get the idea that they do not have to work because the other half is going to take care of them, and the other half gets the idea that it does no good to work because somebody else is going to get what they work for, that my dear friend, is the beginning of the end of any nation. You cannot multiply wealth by dividing it! when you rob Paul to give to Peter ... ... ... you will always get Peters support! :Brieffromnativea: |

Quoting: Anonymous Coward 928398It is old news... We are 20 years beyond in what the general public knows. At least 20, if not light years. Problem is, how to we get them to fess up and share? |

Quoting: Chapman_BaxterThanks, I got it just fine. Very interesting, such a showman, ain't he. Anyway, I couldn't help asking myself just how they knew that the Kevlar material would only support 2 or 3 people for a journey from earth to space without having tried it out already? Formulas and models are one thing, but to think they haven't been testing this out under real conditions already is just a bit naive. |
