On the Elevator in Space - 2009
Shortly after the news about the winner of the competition for the construction of lunar landing modules, another one arrived. The research teams, space, and a million dollars are again appearing.
At this time, the team has already received $ 900,000 - a participant in the annual Space Elevator Games 2009 competition for the construction of a space elevator. The competition is held November 4-6. This year the task is to build an elevator that rises along the cable to a height of 1 km at a speed of at least 5 m / s for receiving the main prize of $ 1.1 million and at least 2 m / s for receiving $ 0.9 million.
Elevators are powered by laser beam energy. Managing this beam to ensure uninterrupted power is a serious task that today only one of the three announced teams to compete - LaserMotive - managed to solve. But they did not go as smoothly as they would like. After the first 300 meters, which the platform flew at the required speed of 5m / s, the speed dropped dramatically, and although it was able to recover, 5m / s did not work - only 3.5 m / s. Here is what happens in the laboratories and on the test sites of teams:

What else is interesting - the competition is given only 45 minutes a day. Not because the participants and the jury are tired. And because this is the only window when there is no danger of damaging any satellite in orbit with a laser.
Yes, the future is almost here.
