#2105: Powerachute

I’ve seen plenty of videos which seem to show ordinary quadricopters comfortably transporting a mass of 1kg.

That set me thinking about a new kind of parachute.

Let’s assume that battery weight takes up say 90% of that 1kg.

Wire together 1000 or so individual quad rotors into a dome shape, like a parachute.

As a jumper falls, each of these spins, acts as a dynamo and stores energy in a central battery.

Near the ground, the dynamos switch to being motors and the battery drives them so as to break the parachutist’s fall.
