Electrostatic motors feature efficiency, high power-to-weight ratio, and no need for magnets or maintenance-heavy gearboxes

"apply voltage to metal tracks attached to printed circuit board creating interaction between rotor/ stator generating motion (instead of copper coils/ magnets creating motion through magnetic fields)... uses >90% less copper, up to 80% lighter), lower cost... significantly lower current so generates almost no heat/ requires no active cooling, direct drive capable/ high torque at low speeds... dielectric fluids boost field strength)... EVs (extend range up to 25%), solar drones, electric aviation, large-scale industrial pumps"
