I just watched a nice video of drone surfing on LinkedIn: https://www.linkedin.com/feed/update/activity:6501182000831963136/
This video link might work:
I immediately thought how drones powerful enough to ‘kite-surf’ would also be useful in new forms of parkour (free running), enabling stunts that wouldn’t be possible otherwise, or acting as a sort of safety net during practice to cushion any falls.
My second thought is that it might soon be feasible to use drones as a substitute for parachutes. Someone could jump out of a plane and the drone could slow their descent, or allow them to travel long horizontal distances during descent or to perform elaborate tricks. That could make a whole new kind of extreme sport, allowing the sorts of things people do in free-fall jumps over much longer times and distances and giving far better control of relative speed between jumpers.
Using auto-gyro effects, some stages of a fall could be used to recharge batteries to power rotors for the next phase.
Fun, though not for the faint-hearted perhaps.
