Lighthouses: Guardians of the Seas in Extreme Conditions
Written on
Introduction to Lighthouses
This article serves as the second installment in our four-part series dedicated to lighthouses. We are pleased to have you back for another exploration. In this piece, we will delve into lighthouse enhancements, contemporary designs, notable builders, and the technologies that power these essential maritime beacons.
Lighthouse Keepers: Their Legacy
Lighthouse keepers played a crucial role in maritime safety and took immense pride in their work. However, advancements such as electrification and automatic lamp changers rendered their positions largely redundant. Despite this, many lighthouses continued to employ keepers for years, as they could also function as emergency rescue services when needed.
Lighthouse Advancements
The progression of maritime navigation technologies, including satellite navigation and GPS, has led to the gradual elimination of traditional lighthouses around the globe. Nonetheless, Canada has bucked this trend, maintaining 50 staffed light stations, with 27 located on the West Coast.
Modern Lighthouses: A New Era
Today's lighthouses utilize stationary flashing lights powered by solar-charged batteries, which are often mounted on robust steel towers. In instances where solar energy falls short, diesel generators step in to recharge the batteries, thus extending the intervals between maintenance.
Famous Builders of Lighthouses
Numerous distinguished individuals have designed and constructed noteworthy lighthouses over the years. Here are some of the most prominent figures in lighthouse architecture.
John Smeaton
John Smeaton is celebrated for designing the iconic Eddystone Lighthouse, known for its innovative engineering.
The Stevenson Family
A family of lighthouse builders in Scotland, the Stevensons (Robert, Alan, David, Thomas, David Alan, and Charles) established a legacy that spanned three generations.
Richard Henry Brunton
Brunton is known for creating 26 lighthouses in Japan during the Meiji Era, affectionately referred to as his "children."
Alexander Mitchell
Blind Irishman Alexander Mitchell is credited with inventing the screw-pile method, allowing for the construction of several screw-pile lighthouses.
James Douglass
James Douglass gained recognition for his work on the fourth Eddystone Lighthouse, which earned him a knighthood.
George Meade
Lieutenant George Meade, famed for his leadership at Gettysburg, also constructed numerous lighthouses along the Atlantic and Gulf coasts.
Orlando Poe
Colonel Orlando M. Poe, an engineer during the Civil War, designed intricate lighthouses in challenging locations across the U.S. Great Lakes.
Marius Michel Pasha
French officer Marius Michel Pasha built nearly a hundred lighthouses along the coasts of the Ottoman Empire following the Crimean War.
Technological Innovations in Lighthouse Design
The lamps used in lighthouses have evolved significantly, with advancements in optics and light sources influencing their operation.
Powering the Light
The late 18th century saw the introduction of the Argand hollow wick lamp and parabolic reflector, which dramatically improved illumination.
Parabolic Reflectors
Parabolic reflectors are critical for collecting and directing light. These devices have applications in various technologies, from satellite dishes to solar cookers.
Fuel Sources
Light sources have transitioned from whale oil to kerosene, and now to electricity and acetylene gas. The Dalén light, which utilized carbide, was a significant innovation that automated light management.
Generators and Power Sources
During the Cold War, Soviet lighthouses relied on radioisotope thermoelectric generators for continuous power without the need for frequent refueling. Unfortunately, many of these lighthouses have since fallen into disrepair.
Light Sources: Evolution and Innovation
Modern lighthouses have transitioned to rotating aerobeacons, which require less maintenance than traditional Fresnel lens installations.
Omnidirectional Flashes
High-intensity lights now produce omnidirectional flashes, which are essential for maritime navigation.
Laser Light: The Future?
Laser technology has been explored in lighthouse illumination, though challenges related to installation and visibility have limited its widespread adoption.
