Lightning rod
Lightning rod protecting a building from damage by a lightning strike. The lightning rod is the strip of metal (green) to the left of the drainpipe (black). The rod runs from the highest point of the building (the wind vane at top centre) where a bolt of lightning is more likely to hit, down to the ground (not seen). The metal lightning rod is a better conductor of electricity than the bricks, and conducts the electricity to the ground where it safely dissipates in the earth. This avoids the explosive damage and fires of a lightning strike. Lightning rods, invented in the 1750s, are often made of copper

EDITORS COMMENTS
This print showcases the ingenious invention of a lightning rod, designed to protect buildings from the destructive force of lightning strikes. Positioned to the left of a sturdy drainpipe, this green strip of metal acts as a safeguard against potential disaster. The lightning rod extends from the highest point of the building, where an ominous wind vane stands at top center, attracting bolts of lightning that are more likely to strike. The purpose behind this architectural marvel becomes clear as we delve into its functionality. Made primarily from copper—a superior conductor of electricity compared to bricks—the metal lightning rod channels any electrical charge safely down towards the ground, hidden from view in this image. By doing so, it prevents explosive damage and devastating fires that often accompany a direct hit by lightning. Dating back to their invention in the 1750s, these technological wonders have become synonymous with protection and safety for structures worldwide. Their presence is not only an embodiment of engineering prowess but also serves as a physical testament to mankind's ability to harness natural forces for our benefit. Intriguingly blending elements of physics and architecture, this photograph captures both artistry and practicality within its frame. It reminds us how human ingenuity has continuously evolved over time—developing innovative solutions like these essential equipment pieces—to ensure our well-being amidst nature's most powerful phenomena.
