Abstract: When a GPS unit electronically detects being within a boundary, a motor controller electronically controls providing electrical power from a battery pack to a high-speed electric motor directly driving a rotatable turbine rotor inside a cylindrical housing at operational speeds. The motor controller electronically controls the high-speed electric motor to stop rotation, to rotate at operational speeds, or to rotate at turbo boost speeds. A single remote electronically controls multiple motor controllers. The motor controller inverts DC battery voltage of 100 volts to 3-phase alternating current used by the high-speed electric motor. A DC-DC converter is electrically connected between the battery pack and a nozzle motor and a display.
