London museum uses brain waves to pilot a huge balloon

The weather balloon is controlled by visitors’ minds. The electric pulses from their brains power the robotics, which, in turn, control the airship. It will float up, down and around for the eight days of the London Design Festival. Practically, the technology can help those who are tense learn to relax and provide soaring adventures for those unable to move.
