One i so in a magazine idea about a elivator, was it all the down to the ground because it didnt mention it just said 36,000 km long elivator all the way to the base?
So my idea has nearly the same way but insted fishing system
that will click to the flying machine and pull it up?
It is just a theory?

Can it also sug some air by the earth atmosphere and use it in a base collecting all the air?

Wow, are you typing with your elbows or something? I can't really figure out what you are trying to say!

Anyways, there are lots of ideas about space elevators. You can read the Wikipedia entry for an overview.

I don't know if any of them involve a system to harness an airplane in flight to an elevator and hoist it into orbit - if that was what you were trying to get at.

The trouble with the space elevator is that no known material is able to suspend itself over that great a distance. The weight would be so great that no matter what material was used it would fall apart.
Explanation:
If you had a rope that could hold up a ton of material the rope would break when you let out so much rope that the rope itself weighed more than a ton.
One might think that you could just splice two ropes together but it would weigh twice as much and thus not be able to be any longer than one rope.
If on the other hand you spliced in another rope only when the first rope was approaching the point where it was going to break and continued to splice in additional ropes as one progressed up into the sky each time the rope approached its carrying capacity one might think that one could continue in that manner to complete the 36000 km. The reason this does not work is that each additional rope adds less additional length to the cable. With any known material that could be used to create the rope the sequence of lengths of rope comes to a limit that is less than the 36000 km.

it's also known as a "Clarke", after Arthur C Clark the science fiction writer ( 2001 and about 50 other books) who also came up with the idea of telecommunications satellites......

You know about geo-sync orbit, right? A Satellite orbits the Earth at 22,000 miles...at that height it is going as fast as the Earth is turning below it, so it seems to stay in the same place in the sky.....that why your satellite TC antenna is always pointed at the same direction,and not constantly moving to track satellite.......

anyway, you build a really big hotel/space dock/city in orbit...some people have talked about bringing an asteroid in from beyond Mars and parking it in orbit......you then construct and lower a really thick cable of carbon nano tubes down to the Earth,anchor it well.......you now have a cable that space liners......something say bigger than a 747 but smaller than a cruise ship can crawl up, taking thousands of people and millions of tons f freight to spaceship waiting beyond Earths gravity...........the beauty of this plan is that the spaces liner gets its power from generators on the ground........like a train gets its power from overhead cables and or a third rail....so you leave your engine at home!

The big drawback to space travel is the power needed to get things into and then out of orbit..we can do it ( see the Apollo missions) but its fantastically expensive.....with a Clarke the power plant stays on Earth and the Solar System is ours.......

People are building carbon fiber nanotubes in California; the rest is known engineering. It may take few bucks, but think how much was spent building ships for 300 years to get people to America.......

I guess you are talking about a proposed elevator to the edge of space, to me this is so far fetched as to warrant no comment on it.
