Forget batteries, CoulombFly is a cylinder-shaped drone with an integrated solar-powered motor. More specifically, an electrostatic flyer that consists of an electrostatic-driven propulsion system with a high lift-to-power efficiency of 30.7 g W and an ultralight kilovolt power system with a low power consumption of 0.568 W.
The motor is composed of an inner ring of stationary charged plates called the stator. These plates are made from a thin carbon-fiber plate covered in aluminum foil. When in use, the neighboring plates have opposite charges, while a ring of 64 rotating plates surrounds them. When the plates in the outer ring are charged, the motor activates, and since one of the nearby plates on the stator has the opposite charge, the pull will start the rotating ring turning.
- No Registration Needed - Under 249 g, FAA Registration, and Remote ID are not required if you fly for recreational purposes.

- Striking Vertical Videos are Ready to Share - With True Vertical Shooting, you can easily capture tall landmarks like skyscrapers and waterfalls.
Limited flight duration is a considerable obstacle to the widespread application of micro aerial vehicles (MAVs), especially for ultralightweight MAVs weighing less than 10 g, which, in general, have a flight endurance of no more than 10 min,” sid the researchers.
