Thoth Technology of Pembroke, Ont. is developing a 20-kilometre-high free-standing space elevator that would allow astronauts to launch into space from a platform high above the Earth. Launching into space vertically would not be necessary, saving more than 30 per cent of the fuel of a conventional rocket. The project will cost between U.S. $5-billion and U.S. $10-billion and could take three to five years to complete the demonstration tower, and another three years to finish the full version.
