Desired Outcomes of this Project
Develop a lightning detection and prevention device that can dissipate lightning, unlike a lightning arrestor (Franklin rod) which attracts lightning strikes and conducts the charge to ground.

Lightning Strikes
When harsh sunlight hits the surface of the earth, water from the surface of the earth turns into water vapor and rises in to the atmosphere to create clouds. These are called cumulus clouds. These clouds get together to form bigger clouds start growing vertically in the sky. They get taller and taller until they represent huge powerhouses, storing a large amount of energy. These clouds are called cumulonimbus clouds, or better known as thunderclouds.
In thunderclouds, electric charges are generated due to collision of ice particles and hail pellets due to the flow of air in the cloud. The electrical charges are distributed and roughly separated in different portions of the cloud. Negative charges tend to gather at the bottom of the cloud and positive charges move to the top of the cloud.
When these charges accumulate, the charges on the surface of the earth or water also start accumulating.
Figure 1 - Lightning strike when a lightning rod is implemented
Such a large distribution of electrical charges generates a large electrostatic field between the thundercloud and the surface of the earth. As the electrostatic field develops, an advanced discharge extends from the both the earth as well as the base of the cloud.
The electrical discharge from the thundercloud is called a stepped leader. The voltage in the stepped leader is very large (about 500,000 million volts to 1 million). As the stepped leader comes near the earth, the charges from the earth start reaching out to the stepped leader.
The electrical discharge from the ground to the stepped leader are called rising streamers. The stepped leader makes contact with the rising streamer to create a lightning strike.
The positive charges start moving towards the cloud and the negative charges move to meet the nearest point to diffuse. This is when lightning occurs.
Additional notes:
- Electrical discharges take place constantly in the cloud and with other clouds. These are called inter cloud (IC) and cloud-to-cloud (CC) lightning. When the lightning happens from cloud to earth (ground), it is called a Cloud-to-Ground (CG) lightning.
- The above example is when the negative charges accumulate at the base of the cloud and form a stepped leader, and positive charges from the ground form a rising streamer, the lightning strike that occurs is called Negative Cloud-to Ground (Negative CG) lightning strike.
- If the positive charges accumulate at the base of the cloud and form a stepped leader, and negative charges from the ground form a rising streamer, the lightning strike that occurs is called Positive Cloud-to-Ground (Positive CG) lightning strike.
- If the discharges from the ground to cloud are stronger, a lightning strike is caused from the ground to the cloud. This is called Ground-to-Cloud (GC) lightning.
Why this is important
Lighting strikes can cause severe damages to human lives, buildings, property, boats and seapods. For over 200 years, the recommended method for lightning prevention is a lightning rod, also called Franklin rod, named after it's inventor, Benjamin Franklin. A lighting rod, or arrestor directs the lightning discharge to ground. The lighting rod is a metallic conductor placed at the highest point of a building or structure and connected to a copper rod buried deep in the ground. When lightning strikes, the electrostatic discharge is safely conducted from the lightning rod to ground without causing damages to buildings or structures. While the lighting rod is widely used in today's world, there have been incidents of damages to the rod and to the buildings and structures because of the intensity of lightning.
Lightning rods do not prevent lightning. They attract lightning and conduct the electrical discharge to the ground.
