This week's Question: Last month, the Canada-based company Thoth Technology received a US patent for its 12-mile space elevator design. The elevator, enclosed in a tunnel, includes a landing pad on its roof. Spacecraft would refuel and take on passengers and cargo from the pad. Some of the elements of the elevator, however, have yet to be invented, including a tether cable that is lightweight and can withstand the tension of the lift technology. There is also concern about high winds and the possibility of the tower buckling under its own weight.

What do you think? Will elevators take us to the edge of space?
