An Inflatable “Space Elevator”

Thoth Technology has successfully patented an inflatable “space elevator” that is so tall, it will would reach into low Earth orbit. The proposed structure is planned to be 20-kilometers-high (compared to the world’s tallest building, the 830-meter-high Burj Khalifa) and will be used for both sight-seeing activities and for space cargo deliveries. By launching space crafts from the tip of the tower, rocket fuel consumption would be cut by a third, making reusable space ships more practical. If pursued, the tower could take up to 10 years to construct at a cost of $5 billion.
