A vehicle-mounted device that uses triboelectric materials and airflow to generate an electric current during vehicle movement

Abstract

A vehicle-mounted device that uses triboelectric materials and airflow to generate an electric current during vehicle movement, characterized in that the friction of a triboelectric material against air is used to generate an electric charge.

Description

[0001] Air is a triboelectric material and occupies the highest position in the triboelectric series. When air rubs against another material in the lower part of the triboelectric series, it releases electrons and charges that material. Cotton is triboelectrically neutral. Steel is located directly next to it and interacts triboelectrically with other materials to a minimal extent. Detailed information on the properties of various triboelectric materials can be found in the triboelectric tables.

[0002] A flying aircraft receives an electrical charge with an electrical potential of up to 200-300 kilovolts. As the aircraft approaches the runway, an electrical discharge occurs between the aircraft and the ground.

[0003] Air is in constant contact with the vehicle. If the vehicle body is isolated from the ground, the same phenomena as in an aircraft could occur in a ground vehicle. If the vehicle body is covered with triboelectric material, the charge accumulation increases.

[0004] In helicopters, the propellers are the main source of static electricity. When the propellers are covered with triboelectric material, the accumulation of charges also increases.

[0005] From the theory of atmospheric electricity, we know that the Earth is negatively charged overall. The charge above the ground is predominantly positive.

[0006] Simple propellers can be used to generate static electricity due to air friction. The propellers can rotate due to the incoming airflow. Coating them with a triboelectric material that absorbs electrons when rubbing against air increases the accumulation of electrical charges. When the propellers are arranged in a tube, Bernoulli's law states that the airflow velocity in the tube increases, leading to an even greater accumulation of electrical charges.

[0007] Air occupies the highest position in the triboelectric series. Therefore, during triboelectric interaction, air releases the maximum possible number of electrons compared to other triboelectric materials. When air rubs against another triboelectric material at the bottom of the triboelectric series, it transfers electrons to it. This creates a potential difference between the triboelectric material and the air above the ground. This process occurs continuously for moving objects such as cars, trains, airplanes, and helicopters. In land transportation, the electrons accumulate on the outer surface of the vehicle. To maintain the electrical charge, the outer surface of the vehicle should be insulated from the ground.

[0008] The proposed device utilizes several methods for generating power using triboelectric interaction. The first method involves attaching two dielectric substrates to the vehicle. A conductive material smaller than the substrate (the first electrode) is attached to one substrate. A triboelectric material from the lower part of the triboelectric series is attached to the substrate. A triboelectrically neutral conductive material, such as steel, smaller than the substrate (the second electrode) is attached to the second dielectric substrate.

[0009] As the vehicle moves and the triboelectric material rubs against the air, the charges are redistributed. Due to its triboelectric properties, air releases electrons, and the triboelectric material accumulates them. Thus, the surface of the triboelectric material on the vehicle and the electrode attached to it will acquire a negative charge. It is known that the environment above ground has a positive charge. Therefore, the second electrode, a steel on a dielectric substrate, will acquire a positive charge. Two electrodes have opposite charges, and a potential difference occurs between them.

[0010] In triboelectric interaction, it is important to achieve a high contact area at the interface of triboelectric materials. This can be achieved in several ways: by using ultra-smooth surfaces, by using special surfaces (wavy surfaces), and by increasing the contact area. To increase the contact area of ​​the triboelectric material with air, a triboelectric material with a wavy surface can be used. The examples are in Fig. 1 and Fig. 2. To increase the contact area of ​​the triboelectric material with air, a tubular structure with thin tubes can also be used. Conductive tubes with an outer and inner triboelectric coating are insulated from the vehicle surface. Examples are shown in Fig. 3 and Fig. 4. This significantly increases the contact area of ​​triboelectric materials with air and the number of charges on the triboelectric material that accepts electrons. This tubular structure can be located on the roof of the car or at the front at the level of the hood.

[0011] Propellers can also be used inside the tubes. The propellers are mounted on horizontal axles inside the tubes. The conductive blades of the propellers are coated with triboelectric material. The blades receive electrons during triboelectric interaction. The tubes are insulated from the vehicle surface. The inner and outer surfaces of the tubes, which are made of conductive material, are covered with a layer of material from the lower part of the triboelectric series. The axles on which the propellers rotate are conductors. The axles are attached to the inner surface of the tubes with conductive materials. The charges accumulated on the blades can flow into the conductive material from which the tube is made (the first electrode). A small, triboelectric, neutral, conductive material (a second electrode) is attached to the vehicle surface on a separate, dielectric substrate.

[0012] When the vehicle moves, the airflow enters the tubes and rotates the propellers. According to Bernoulli's law, the airflow velocity inside the tube increases compared to the air velocity outside the tube. Increasing the rotation speed of the propellers accelerates the electron exchange between triboelectric surfaces and the airflow. The position of the propellers in the tubes is in Fig. 5 shown.

[0013] Charges from the propellers, through the axles and their mountings in the tube, fall onto the conductive material in the inner surface of the tube. The tubes with propellers can be located on the roof or in the front of the vehicle. As the vehicle moves, a potential difference arises between the conductive materials on the inner surface of the tubes and the steel electrode mounted on a dielectric substrate.

[0014] The proposed device for generating power using triboelectricity can be used to charge vehicle batteries while driving. The proposed device can also be used for lighting and heating a vehicle.
