A towering structure rising 20 kilometers into the air with its top in the sky may sound like something out of an Old Testament passage or science fiction novel, but a Canadian space company has proposed just that to cut the costs of space exploration.
Last month Thoth Technology was granted a United States patent for a “space elevator,” which would be more than 20 times taller than the 829-metre-high Burj Khalifa in Dubai, the tallest building in the world. That is also beyond the so-called “Armstrong limit” – a point at an altitude of 19 kilometers where body fluids start to boil off due to low air pressure.
“The space elevator tower has a segmented elevator core structure, each segment being formed of at least one pneumatically pressurized cell. The pressure cells may be filled with air or another gas,” the patent states. ∞∞∞∞∞ MORE »»»»
