How Do Lighthouses Work?

[@gormauslander]

Keeper of the light is without doubt the greatest title imaginable

[@BCLighthouseKeeper]

There is a book with this title written by Donald Graham that is about the history of many of BC's lighthouses. Worth a read if you like lighthouse history.

Hi TTK...I'm a Lighthouse keeper from india..glad to see your video on Lighthouse service. Thanks and take care😇👍

[@Kookaburrow]

Awesome video!! I loved seeing how you went in detail about fresnel len's. Here's a fun fact which you didn't include but I recon is really interesting; Many of the older and more heavier fresnel len's which are still in operation today are actually floating in mercury, a liquid which has great kinetic properties, allowing these extremely heavy lenses to be operated using small and energy efficient motors. This method is used at both the Cape Byron lighthouse and also the Cape Otway lighthouse in Victoria, which both have very large lenses. You can actually climb the Cape Otway lighthouse and when you're at the top, although the lens is elevated above you so you can't physically see the mercury, the motor mechanism is on display as it operates and it is truly incredible how something so small can power a lens of that size!! Definitely worth visiting if you live in Victoria because the whole light station is open to the public and it has a ton of history attached to the lighthouse. Hope that was interesting, keep making amazing video's, you've earned a new sub

[@tvoommen4688]

I have worked in an effluent treatment plant that has a huge sprinkler (30 meters across) pivoted in mercury, and rotates like a garden sprinkler without need of any motor . Mercury is highly corrosion-resistant too.

[@Kookaburrow]

@@tvoommen4688 That's incredible!! Mercury is truely impressive stuff, despite how dangerous it can be!

[@garrettallen7427]

Hope you’re staying safe during the pandemic, love your informative videos!

[@TicketToKnow]

Indeed! My trip that I mentioned was before all the lockdown and distancing. I have been at home for weeks now! I hope everyone watching is staying home if they can!

[@grantb8168]

Yet another great video, TTK. Apart from the simplistic point of a lighthouse, I had no idea about the intricacies of their evolution. Your video shows the creativity and invention of certain individuals of our species. Thank goodness for those people who look to the betterment of all and help us continue forward, safely. Some of the lenses surrounding the lamps are quite beautiful and extraordinary. Thanks again for the knowledge and entertainment and I hope during this difficult time of the global pandemic, you are keeping safe and healthy.

[@flyingdutchman3237]

In dutch a lighthouse is called a ''vuurtoren'' translate: "firetower." now I know where that name comes from.

[@wolfyk95]

The US has Fire towers, but the term refers to tall cabin like structures in the forest to spot forest fires.

[@ilhamga7956]

Why did youtube recommends this channel so late to me ? Your video is awesome man!

[@Frederic_S]

The keeper of light did a very good job explaining what makes a lighthouse a lighthouse.

[@aaronrudd3943]

Love the round the twist Easter egg, theme music too! Without my pants

[@milleretguillaume9374]

The strips are white and black because the black ones are visible whith good weather and the whites are visibles during storms

[@AverageAlien]

wouldn't the white be hidden during a storm?

[@PIRANHA_MAN]

You mean more than one colour.

[@Lianls79]

The only reason I’m watching this is because I had a dream of me learning how to light up a lighthouse and while watching this my dream was TOTALLY different compared to the real thing🤣

[@DlveenPharm]

I understand alot thank you for this idea 🎉❤😊

[@Marco-qc9yu]

I prefer to differentiate the type as such; LIGHTHOUSE: a structure with accommodations within, as in the lantern room is set in the roof structure of the dwelling or the keeper lives within the tower or an integrated house structure. otherwise it’s a LIGHTSTATION, where the keeper lives onsite to maintain and operate the LIGHT TOWER. Source: I’m a former lighthouse keeper working 13 different stations during my career. Excellent video

[@CrazyAika94]

I feel blessed to have this channel recommended. This is really interesting. Great video 💕👍!

[@sachabertrand4604]

« The light between between oceans » Anyone who liked this video should see that movie if they haven’t. Really nice vid, made my day ;-)

[@Shipwright1918]

Fishermen still tend to use lighthouses, particularly to fix a good fishing spot, as GPS fixes can wander around from day to day, while taking bearings off of the light and other landmarks will get you to the exact spot every time. Even the big ships will still take bearings as a backup, and to double-check that their nav plots are accurate.

[@rainbowgalaxy1668]

[@tylermech66]

@@rainbowgalaxy1668 He DID say "to double-check" and "as a backup", redundancy, it's a thing that's useful for not dying.

Around the Twist was an awesome Aussie Tv Show :D

[@darylcheshire1618]

I saw a lovely documentary about a ship that travelled around Australia and resupplied lighthouses. It even had a boat with wheels which was lowered over the side and could be driven up the shore.

"Have you ever, ever felt like this Have strange things happened, Are you going round the twist" Childhood banger here in the UK 🇬🇧🇦🇺

[@davidpanton3192]

Great stuff, thanks. I used to live near Inchkeith lighthouse on the Firth of Forth, Scotland. Through binoculars I could see that it had a bank of LEDs (probably) which rotated inside the lamp room. This seemed rather an odd compromise; perhaps the LEDs had to be flat to be bright enough which meant they couldn't be static and flash.

[@johsiantorres8495]

I love light houses im so obsessed with the great lakes especially lake Ontario

[@DB-thats-me]

Having relied on lighthouses to guide me, even in the modern electronic world, I cannot express my gratitude and thanks for these ‘beacons of safety’, maned or not. Sometimes the light in the darkness is more reassuring than the ‘blip’ on a screen.

I'm taking a wild guess here ....... A bloody great big light bulb and some sort of rotating reflector? That's 10:50 saved! Glad I could help! 👍😂😂😂

[@robinj1052]

What makes a lighthouse a lighthouse? Primarily the visibility range of the light. Where inland Aids to Navigation typically have a range of up to 5 nm, offshore AtoN up to 15 nm, lighthouses have ranges up to 25 nm (sometimes even beyond that). Where nm stands for nautical miles. That the range is so important for a lighthouse, is proven by the size of the Fresnel lenses, which you simply cannot not put on buoys, for example. And which are not required on inland waters, unless the inland water happens to be a very large lake or inland sea. A second proof, is the height of the light compared to sea level: the higher the light, the larger the visibility range. With the invention of AIS, the necesity for long range lanterns is being reduced. When lighthouses are converted from tradional incandescent lamps to LED light sources, very often the visibility range is reduced significantly. Eg in Belgium you see a reduction in range from over 25 nm to around 18 nm, when converting to LED. Despite AIS, visible beacons are still very useful and reliable. You see them everywhere: buoys, Morse U lanterns on offshore installations, port entry lights (PEL lights), sector lights, etc. Typically lighthouses also had fog signals installed, but these are not in use anymore these days. At the Lighthouse Museum in Fraserburgh, Scotland, you can still see them in situ.

[@jst7714]

At 9:16, I'm proud to say that not only have I climbed that lighthouse, I've worked and volunteered at that museum. That's the Ponce Inlet Lighthouse in Florida.

[@mehrbodjanatian6768]

Thanks alot

[@privateerbouncher9622]

I used to be on vacation with my family at my grandads brother in Denmark on the island Samsoe. He lived right at the coast, and we could see the Lighthouses on Zealand (Roesnaes and Asnaes) But also pile beacons/Pile lighthouses at Hatter Barn seabed and Hatter Reef. I know the Hatters are piles, as you can just search them up. I found something unsettling yet fascinating about watching that silent flash.

[@nunyabiznes33]

I never knew that individual lighthouses have their own "pulse" signature.

[@Staniele]

I’ve always liked lighthouses, probably because in my country we don’t have one we do have a coastline but no actual lighthouses. The closest lighthouse is probably the one in Trieste and is visible from the Slovenian coast and it’s absolutely majestic.

[@stinker43]

I live in Northern California, and have sailed from San Francisco north to Bodega bay (The Birds!) south to Monterey. That required me to pass multiple lighthouses and light stations. Point Bonita (at the entrance to SF Bay), Point Reyes (26NM visibility-with the Fresnel lens still in operation) down south to Point Sur Light Station. In the US, a light station is/was a lighthouse too far or difficult from cities to easily provision the lighthouse at the time. I am a lighthouse afficionato.

Some lighthouses have used Strontium-90 as a power source. The Baltimore Harbor Light was one of them.

Similarly in aviation Using NDB and VOR stations. Morse code sound can be used to identify the station used. Nice to see aviation and mariners use similar methods with navigation.

no, there is still light houses, that are the old ones, where electricity is not a thing yet, on places far away in the seas, a light housekeeper, uses charcoal to generate electricity, and they have a house where they stay for months taking turns with other light house keepers, they earn good money

The first building in the world and at the same time a lighthouse made of industrial cement. The lighthouse building in Port Said on the Suez Canal in the Republic of Egypt is not used now because it is a museum owned by the world.

Lighthouses also have Foghorns to tell ships to stay away from the rocks

[@ramsesrameez5430]

As we know light is very important in life. Without a light house ships can't see where the beach is or where they path is ...

[@Nani22334]

Unexpectedly, if there is any power shortage in the midnight, what is the back up they have to navigate mariners.

[@darylcheshire1618]

At Queenscliff ships have to navigate in a curve to enter the heads of Port Phillip Bay and so use two lighthouses, a white one and a black one made of bluestone. The correct angle to enter the heads is to line up the two lighthouses.
