Although the idea of a space elevator has been around for decades, the space technologies needed to support it have yet to be created so the non-profit Spaceward Foundation has hosted an annual competition since 2005, supported by a cash prize from NASA, to build a super-strong tether similar to what would be needed to support a real elevator, or get a robot to climb a suspended ribbon. In the robot climber competition, teams have to get their device to hurtle up a 100-metre-long ribbon, suspended from a crane, at an average speed of two metres per second. The climber must be powered from the ground: strategies include reflecting sunlight from huge mirrors on the ground to solar panels on the climber; shining lasers from the ground up to similar panels on the robot; or firing microwaves up at the climber. Qualifying rounds have been taking place all week, and although high winds and rain have caused delays, four out of eight teams have made it into the finals. There are no outdoor climbs today because of bad weather but that some of the tether competitions will happen indoors later this afternoon."
