Understanding Atmospheric Electricity and its Power Source

Atmospheric electricity is a fascinating natural phenomenon that can be harnessed to power certain devices. This article aims to provide a comprehensive understanding of atmospheric electricity, how it works, and its potential applications.

1. Introduction

Imagine being able to generate electricity from the atmosphere itself. It may sound like something out of a sci-fi movie, but it is possible. Atmospheric electricity refers to the electric charges present in the Earth's atmosphere, which can be utilized as a power source under the right circumstances.

2. Understanding Atmospheric Electricity

2.1. Voltage Increases with Altitude

As you ascend higher into the air, the voltage increases significantly. For every meter you go up, the voltage rises by approximately 100 volts. These voltage increases can be graphically represented using equipotential lines, which show the distribution of voltage in the atmosphere.

2.2. The Ground-Sky Polarity

The ground and the sky have opposite polarities. The ground is negatively charged, while the sky is positively charged. According to the findings of Nobel laureate Richard Feynman, this polarity extends upward to about 50 kilometers (31 miles). However, this is primarily applicable to fair weather conditions.

2.3. Conductivity in Fair Weather and Stormy Weather

In fair weather, the atmosphere is highly conductive, allowing the transmission of electricity. However, during stormy weather, the dynamics change significantly, and the phenomenon becomes more complex.

3. The Lack of Shock on the Ground

One might wonder why a person standing on the ground does not experience an electric shock due to the existing voltage between their head and the ground. The explanation lies in the fact that the human body is an electrical conductor. Thus, while standing on the ground, the body becomes part of the equipotential lines, resulting in an effectively zero-volt difference between the head and the ground.

4. The Concept of Equipotential Lines

Equipotential lines are imaginary lines that connect points with the same electric potential. In the case of atmospheric electricity, these lines show the distribution of voltage in the atmosphere. The lines are closer together near objects such as trees, buildings, or the wire used to harness atmospheric electricity.

5. The Existence of a Downward Electrical Current

Apart from voltage, there is also a downward electrical current in the atmosphere. This current consists of positive ions, molecules, or clumps of matter that possess a positive charge. These ions move slowly towards the ground, resulting in a current density of approximately 10 micromicroamps or 10 picoamps per square meter or yard per second.

6. Power Density and Current Density

The power density of atmospheric electricity, considering the low current density, is relatively low. In small areas, the power generated is not substantial. However, this does not eliminate the potential for utilizing atmospheric electricity in various applications.

7. Utilizing Atmospheric Electricity

To tap into atmospheric electricity, one can electrically connect one end of a wire to the ground and lift the other end high up into the air. By doing so, a voltage difference can be established between the elevated wire and the ground.

7.1. Connecting a Wire to the Ground

The first step in harnessing atmospheric electricity involves connecting one end of a wire to the ground. This ensures that the wire is at ground potential or the same voltage as the surrounding environment.

7.2. Lifting the Wire into the Air

The other end of the wire is lifted high up into the air, reaching an altitude where the voltage difference between that height and the ground becomes significant. For example, at approximately 120 meters (390 feet) above ground, the voltage can reach 12,000 volts.

8. The Phenomenon at Work: Equipotential Lines and Voltage

When the wire is in the air, the equipotential lines surrounding it show a voltage of 12,000 volts existing between the wire and some distance away from it. The closest equipotential lines can be observed at the top of the wire, indicating the strongest attraction for electrons.

9. Concentrated Electric Field at Sharp Points

At the top of the wire, sharp points are strategically placed to concentrate the electric charges. Due to the shape of the point, the charges become crowded together, creating a stronger electric field in that vicinity. This strong electric field is capable of removing the negative electrons from the sharp point, neutralizing positive ions present in the air.

10. The Role of Corona Motors

Corona motors are a specific type of electrostatic motor that can be powered by atmospheric electricity. These motors consist of a plastic cylinder surrounded by sharp-edged metal blades. The blades are connected to the wire leading up into the sky when the wire starts conducting electricity.

10.1. Construction of a Corona Motor

To illustrate the functioning of a corona motor, imagine placing six sharp points using sewing pins at the top of the wire. Although there are multiple points, for simplicity, we will focus on one. Due to the sharp shape of the point, electric charges crowd together at that specific point.

10.2. How the Corona Motor Turns

The electric field exists between the negative charges on the wire and the positive charges in the air. This electric field is represented by lines drawn between pairs of opposite charges. The closer proximity of the electric field lines near the point indicates a stronger electric field. This powerful electric field removes negative electrons from the sharp point, neutralizes positive ions, and initiates electricity flow through the wire. As a result, the corona motor turns due to repulsion and attraction forces on the plastic cylinder and the blades.

11. Conclusion

Atmospheric electricity is a captivating phenomenon that offers a unique opportunity to generate power. By understanding the principles and concepts of atmospheric electricity, such as voltage distribution, equipotential lines, and the functioning of corona motors, we can tap into this abundant and renewable source of energy.
