Airjelly is one of the most beautiful pieces of technology I have ever seen...

AirJelly is a remote radio-controlled airborne jellyfish with a central electric drive unit and an intelligent adaptive mechanism.

AirJelly consists of a helium-filled ballonett with a diameter of 1.35 meters. This yields a filling volume of 1.3 cubic meters of helium. Since one cubic meter of helium provides buoyancy to lift approximately one kilogram, the total weight of AirJelly, comprising its ballonett and all ancillary components, must amount to no more than 1.3 kilograms.

AirJelly houses two lithium-ion polymer accumulator batteries rated at 8 V and 400 mA, which can be completely charged in half an hour and are AirJelly’s sole source of power. A connected central electric drive unit transmits the force to a bevel gear wheel and then to eight spur gears in sequence. These gears power eight shafts, eac”
