What You'll Learn
Lightning rods
A lightning rod, also known as a lightning conductor, air terminal, or strike termination device, is a metal rod that is mounted on a structure to protect it from a lightning strike. The rod conducts lightning to the ground through a wire, preventing the lightning from passing through the structure, where it could cause a fire or electrocution.
The first lightning rod was assembled by Father Prokop Diviš, a Czech priest and scientist, in 1754. Diviš's design was intended to prevent thunderstorms by constantly removing the air of its electricity. His work predated Benjamin Franklin's more well-known lightning rod experiments. Franklin, who conceived the idea for a lightning rod in 1749, speculated that a pointed iron rod would "draw out the electrical fire from a cloud silently, before it could come near enough to strike." Franklin's design became widely adopted across Europe and North America, and his contributions significantly advanced the understanding and application of lightning protection systems.
In the 19th century, lightning rods became decorative, embellished with ornamental glass balls that are now prized by collectors. These glass balls were originally intended to provide evidence of a lightning strike by shattering or falling off, allowing property owners to check for damage to the building, rod, and grounding wire.

Electric fishing rods
The E-ROD™, developed by Dominion Rods, is a notable example of an electric fishing rod. It utilises integrated battery technology, doing away with the need for cumbersome cords or external batteries. The E-ROD™’s internal computer closely monitors battery usage, ensuring a safe and user-friendly fishing experience that can last all day on a single charge. Its versatility is also noteworthy, as it can be mounted on various existing rods and is compatible with different fishing platforms, including jigging and deep-drop reels.
When choosing an electric fishing rod, there are several key features to consider. Firstly, the control panel should be easily readable, even in bright sunlight, to facilitate clear visibility while fishing. Secondly, the power of the electric reel is important, with higher voltage and wattage resulting in greater "winding power" and "winding speed/retrieve rate." Thirdly, line capacity should align with the intended fishing depth, ensuring the reel can handle the required strength and length of the line for the desired depth and type of fish. Lastly, while advanced electric reels may have electronic drag systems, a traditional mechanical drag system with carbon fibre washers is sufficient for recreational anglers.

Ground rods
Solid copper rods, for instance, are ideal for areas with high soil resistivity or high salt content. They are made from highly conductive, hard-drawn copper, which ensures optimal electrical grounding. On the other hand, copper-bonded ground rods offer a combination of strength and corrosion resistance. By bonding copper to steel, these rods provide both ease of installation and long-lasting protection against corrosion.
Today, ground rods are manufactured by companies like nVent ERICO, which offers a comprehensive line of ground rods and accessories to meet diverse customer needs. The installation process can also be made more ergonomic with kits that include the necessary components, such as ground rods, conductor clamps, and drive sleeves.

Lightning protection systems
Strike termination devices, such as air terminals or lightning rods, are metal rods mounted on a structure intended to protect it from a lightning strike. If lightning hits the structure, it will most likely strike the rod and be conducted to the ground through a wire, preventing the lightning from passing through the structure, where it could start a fire or cause electrocution.
Conductors are usually special braided metal cables that carry the lightning strike from the strike termination device to the ground. Bonding connections are used to connect metallic bodies within the structure, ensuring that the lightning strike is safely directed away from the building and its occupants. Surge protection devices help to protect the building's electrical systems and appliances from damage caused by the lightning strike.
It is important to note that lightning protection systems should be installed by trained and qualified specialists to ensure their effectiveness.

Lightning rod history
The lightning rod, also known as a lightning conductor, is a metal rod that is mounted on a structure to protect it from a lightning strike. If lightning hits a structure, it will most likely strike the rod and be conducted into the ground through a wire, preventing fires or electrocution.
History
The lightning rod was invented by Benjamin Franklin in 1749 as part of his exploration of electricity. Franklin's design was for a iron rod about 8 to 10 feet long, sharpened to a point at the end. He speculated that "the electrical fire would, I think, be drawn out of a cloud silently, before it could come near enough to strike."
Franklin's design built on the work of Thomas-François Dalibard, who had translated some of Franklin's books into French. On May 10, 1752, Dalibard conducted an experiment in the village of Marly-la-Ville near Paris, using a tall iron rod insulated from the ground with wine bottles, and succeeded in drawing sparks from lightning.
Franklin conducted his famous kite experiment in Philadelphia in June 1752, where he also succeeded in drawing sparks from thunderclouds.
Franklin's design for the lightning rod soon spread and was widely adopted across Europe and North America, becoming a symbol of the ingenuity and independence of the young nation. The lightning rod constructed on the dome of the State House in Maryland was the largest "Franklin" lightning rod ever attached to a public or private building during his lifetime.
The lightning rod represented a fundamental milestone in the history of electrical safety engineering, changing the course of civilization by allowing humanity to stop being afraid of storms.
Over time, the design of the lightning rod has been improved and sophisticated through the combination of new materials and technologies, such as deionizing lightning rods with electrostatic charge to prevent lightning from forming, or lightning rods with a discharge device to predict when a lightning bolt will be produced.
