20-km-high space elevator a reality soon

  • A Canadian firm has been granted a US patent to build the world's first-ever space elevator -- 20 times the height of the world's tallest building Burj Khalifa -- that will also have a tower assisting spacecrafts to land and take off.

    Ontario-based Thoth Technology has already outlined plans for an elevator to space that will help save enormous amount of fuel and money that go into launching rockets into orbit.

    The company will build a freestanding tower, reaching 20 km above the planet's surface. The elevator will also be used for wind-energy generation and communications. (Source: IANS)
