How high can we build on Earth?

The Experiential High Altitude Platform Organization (www.XHAP.org) is proposing to build Earth Tower One (ET1) which will be 20 miles high and 40 miles wide. ET1 will be a tribute to humanity, built with open source architecture, and based upon the long standing structure of pyramids and mountains!

The reasons to build ET1 are numerous:
* If built above deserts (1/5 of the Earth's surface), the base area within the open framed pyramid can be slowly transformed from desert to farm land by providing shade and by diverting moisture from upper atmosphere to the base.
* Wind turbines and solar panels can be constructed on movable platforms that rotate toward the wind or sun or away from the high winds of hurricanes and tornadoes into protective shells. This can provide power for remote areas.
* Hundreds of Weather stations, Air Quality Monitors, Weather and Aircraft Radars, Cell Towers, Ham and Public Service radio transmitters and repeaters, and Internet routers and access points can be installed within ET1.
* The high altitude platform on top of ET1 can be used to launch Solar Sails and other objects into space using Space Cannons mounted long the top of ET1.
* Telescopes built near the top of ET1 will have a clear view than surface based telescopes.
* Laser beams installed near the top of ET1 can be used to disintegrate space junk then Solar Sails can be used to sweep up the dust and bring it into the atmosphere to burn up.
* If ET1 is built off shore from major cities, it can help protect those cities from tsunamis.
* If ET1 is built in areas of tornadoes or hurricanes, ET1 can be used to create 200 mph wind streams and releasing reverse winds into the paths of tornados or hurricanes to counteract their destructive forces.
* ET1 will be the tallest pyramid on Earth and a tribute to humanity not just tombs to ancient pharaohs.

So the question is: "How high can we built on Earth" (not "Should we built tall Earth objects")?

    Jul 25 2012: Thank you Lawren for your information about the Space Elevator (http://en.wikipedia.org/wiki/Space_elevator)!

    The annual Space Elevator conference is coming up next month in Seattle. The Space Elevator, and the Mega City (http://en.wikipedia.org/wiki/Shimizu_Mega-City_Pyramid) do depend upon carbon nano tubes being developed enough for mass production.

    ET1 started with thoughts about creating a floating experimental high altitude balloon using carbon nano tubes as tethers. And the purpose of this high altitude platform was to launch Solar Sails however the uses of the land based Earth tower could serve many more purposes.

    ET1 (http://www.EarthTowerOne.com) could perhaps, due to not having to support 55 skyscrapers or the distance of a Space Elevator tether, be constructed of materials already mass produced. ET1 could also be used as an anchor station for the Space Elevator. Since objects can be elevated (and lowered) within the closed beams and support trusses of ET1 to a height above (and below) the jet stream, the problems of high winds and temperature upon Space Elevator climbers can be eliminated!

    And the Space Cannons (http://en.wikipedia.org/wiki/Space_gun) mounted at the top of ET1 can also be used to fire projectiles into space. These projectiles can contain the very objects needed for the Space Elevator: such carbon nano tubes and materials to build the Space Elevator Platform.
