Gallery: Japanese Company Announces Plans to Build 22,000-Mile-High Spa...


Scientists have long considered the possibility of creating ultra-tall space elevators that stretch beyond the earth’s atmosphere to transport satellites and shuttles into outer space without the cost and environmental impact of rocket fuels. Now a Japanese company specializing in major infrastructure projects called The Obayashi Corporation has announced plans to build a space elevator by 2050, with the aim of taking tourists 20,000 miles above the planet’s surface.

    Flight seems more practical and faster. I also thought about space junk damaging this structure and proneness to terrorist attacks.

    60,000 mile long cable? it sounds like they intend to make it past the Lagrange point (34000 miles) so that the whole thing is held in place by gravity.

    This is hilarious… 8 day trip x 24 hrs x 125 miles per hour = 24 thousand miles up in orbit?

    I just googled:

    The International Space Station (ISS) is in low orbit around the Earth, and is approximately maintained at an orbit between 278 km (173 mi) and 460 km (286 mi) altitude from the surface of the planet.

    Since the moon’s orbit is elliptical (oval-shaped), its distance varies from about 221,463 miles (356,334 kilometers) at perigee (closest approach to Earth) to 251,968 miles (405,503 kilometers) at apogee (farthest point). The average distance from the moon to the Earth is 238,857 miles (384,392 kilometers).

    So this thing would be 1/4 of the way to the moon, cutting a huge swath thru space….. Good luck

    That would be a lot of steel and carbon nanotube cabling to a structure 22 Thousand miles up. That’s nearly the circumference of the earth, with the associated infrastructure in a type of construction never been done or significantly attempted.

    You’d sooner see a permanent habitation on Mars or the Moon.

    Ummmmm….. does anyone really think this would only cost $6 billion? The tallest building in the world is about half a mile tall. They’re proposing building something 120,000 times as tall as anything humans have ever built, out of materials we have difficulty producing more than a few grams of at a time. Good luck with that.

    Actually $6 billion does not sound that bad considering the numbers being thrown around by company earnings reports and national debts. I’m sure the world bank has that kind of cash floating around somewhere.

    Beam me up! This tickles my imaginative funny bone. I would love to be on this elevator in 38 years time! It seems like it would be at risk of suffering impact from satellites and space junk though?
