An aircraft for distributing granular material on a target area is provided. The aircraft includes an electric sifter, which includes a motor to distribute the granular material on the target area and a screen on the bottom surface of the electric sifter. The screen allows the granular material to pass through the screen to the target area. The aircraft also includes a circuit to activate the motor, one or more power sources to power the motor and the circuit, and an interface for an operator to control the circuit. The granular material is stored in the electric sifter. The operator manipulates the interface to signal the circuit to activate the motor. The electric sifter distributes the granular material when the motor is activated.

1. An aircraft for distributing granular material on a target area, comprising: an enclosure, mounted externally to the aircraft, comprising: a door, mounted on a bottom surface of the enclosure and hinged at a side of the door corresponding to a front of the aircraft and comprising a cutout on the hinged side of the door, the cutout allowing air to flow between the door in an open position and the bottom surface of the enclosure; andan electric sifter, mounted within the enclosure and above the door, comprising: storage space for the granular material;a motor to distribute the granular material on the target area; anda screen on a bottom surface of the electric sifter,the screen comprising: a first portion oriented toward the front of the aircraft, wherein the first portion allows the granular material to pass through the screen when the motor is activated; anda second portion oriented toward the rear of the aircraft, wherein the second portion does not allow the granular material to pass through the screen when the motor is activated, wherein an area of the first portion is less than an area of the second portion;a circuit to activate the motor;one or more power sources to power the motor and the circuit; andan interface for an operator to control the circuit, wherein the operator manipulates the interface to signal the circuit to activate the motor, wherein the motor imparts vibration to the screen, wherein the vibration imparted to the screen is sufficient to cause the granular material to evenly pass through the screen, wherein the electric sifter distributes the granular material when the motor is activated. 2. The aircraft of claim 1, wherein the aircraft comprises a plurality of electric sifters, wherein the operator activates a motor of any electric sifter of the plurality of electric sifters independently from a motor of any other electric sifter of the plurality of electric sifters. 3. The aircraft of claim 1, the aircraft comprising one or more enclosures distributed symmetrically on a horizontal axis with respect to the lengthwise center line of the aircraft, wherein each of the one or more enclosures comprises at least one electric sifter, wherein each of the doors is controlled by an actuator, wherein the circuit controls the actuators to open and close the doors, wherein the operator manipulates the interface to signal the circuit to open and close the doors, wherein the granular material is only released to the target area when a door is open and the motor is activated. 4. The aircraft of claim 1, wherein the aircraft is a rotary-winged aircraft, wherein rotor wash pushes the granular material toward the target area when the aircraft passes over the target area. 5. The aircraft of claim 1, wherein the electric sifter stores all of the granular material above the screen, wherein the granular material comprises pollen in granular form, wherein the first portion of the screen comprises a wire mesh having 6-8 evenly-spaced openings per inch. 6. The aircraft of claim 1, wherein one of a sonar and an optical sensor detects the level of granular material in the electric sifter and provides a notification signal to the operator when the level of granular material in the electric sifter is at a predetermined level. 7. The aircraft of claim 1, wherein the aircraft is a remotely-piloted aircraft, wherein the operator controls the aircraft and the circuit with an uploaded program, wherein an operator interface displays an indication to the operator that the granular material in the electric sifter is at a predetermined level. 8. The aircraft of claim 7, wherein the uploaded program determines when all granular material has been distributed, wherein the uploaded program directs the aircraft to land at a designated location when there is no more granular material to distribute. 9. The aircraft of claim 7, wherein the uploaded program uses aircraft and weather information to determine when to activate a motor, wherein aircraft and weather information comprises at least one of aircraft speed, aircraft position, aircraft height, wind speed, wind direction, GPS position information, and weather information.
