Just a reminder my blog is trans inclusive. It’s bi inclusive. It is pan inclusive. It is intersex inclusive. It is ace/asexual inclusive. It is aro/aromantic inclusive. It is queer inclusive.

I don’t support terfs or exclusionists.

If you came here looking for an ally in your bigotry you came to the wrong blog. Go away. You are not welcome here.

The I love you lighthouse, by Juergen Roth

The I Love You lighthouse is perched facing out into the Atlantic and was build 1855 and sends the first light 1860, on the exposed Minot’s Ledge — named after George Minot, an 18th-Century Boston Merchant who lost a valuable ship on the rocks prior to construction of the lighthouse. The ledge is part of the Cohasset Rocks, off Massachusetts, USA.

When, in 1894, a new flashing lantern was installed in the 34-year-old lighthouse it had a 1-4-3 sequence and very soon the number sequence was taken to represent I Love You (I /1 flash, Love /4 flashes, You /3 flashes). Over the years this simple lighthouse code has been a comfort to sailors from the area, their sweethearts and families.

Lighthouse Beacons

In 1822, French physicist Augustin Fresnel ( 1788-1827) published his ideas on glass prismatic lenses and produced a design that concentrated a beam of light in a particular direction. The beam was five times more powerful than the system of silvered reflectors previously used in lighthouses, and if the light was 30m above sea level, it could be seen upt to 32km away. Fresnel lenses, which resembled giant glass beehives, were soon installed in all French lighthouses, and engineer Alan Stevenson (1807-1865) installed them in some Scottish lighthouses after meeting with Fresnel, but the US Lighthouse Board did not adopt the design until the 1850s.

Lighthouses originally used wood or coal fires to produce light, in the 18th century, John Smeaton (1724-1792) the builder of the third Eddystone Lighthouse used 24 candles in a chandelier as light. Oil lamps became common for a time, mostly from the late 18th- late 19th century. Bell Rock ( Arbroath, Scottland) for example, used spermaceti oil before switching to paraffin in 1877.

Electricity was first employed in the South Foreland Light in the straits of Dover in 1859, at the instigation of Michael Faraday, the great physicist (1791-1867). The first French lighthouse to have an electric beacon was Cap Heve, with a very powerful light for the time of 60,000 candlepower. Each beacon was now given a unique fkash sequence, which was marked on charts, so that the lighthouse could be identified at night.
