How do they build lighthouses in the middle of the ocean?

 The Lighthouse That Couldn't Defy Gravity.

Then in 1939 a handful of men conceived the idea of doing something which seemed to be crazy, to construct a lighthouse on Þrídrangar, three inaccessible rocks jutting out of the freezing North Atlantic off of Iceland. No land. No shelter. Just wind, waves, and stone.

It sounded impossible. But they did it anyway.

They must climb it first,--and that was almost suicide. The cliffs were even wet walls of rock, slippery and cold. They possessed neither gear, nor ropes, nor safety. Where the ascent proved too steep a human ladder was made, the one man standing on the shoulders of the next and the other drawing him up.

A method of transporting people had to be developed before construction. So they cut metal spikes into the cliff and bound them together--a tremulous way of iron floating on the sea. Then there was the supplies, buckets of cement, rowed up out of boats below one after the other, in the teeth of cold wind and smashing water.

A month they had to work that way. No dock. No break. Just survival.

And as the end of it came, there was a lighthouse on a point where no-one believed men could even stand.

It still remains there, alone, silent and laughing at gravity.

How do deep sea oil rigs work?

 

The sea is a big thing.

It does not want to be tamed.

For this the deep water rig does not sit on legs. It floats. It is a great steel island thing-It is held in place by nothing but fire and computers. It has thrusters on its belly. They fight the wind, the current, every second of every day, to stay over one spot on the dark seabed.

From there, a drill string, miles long, is sent down into the muck - The bit at its tip grinds through rock - There is a bigger pipe, the marine riser — This brings the broken earth back up but, the meanest thing sits on the seafloor - The blowout preventer. Basically a stack of steel valves a hundred tons heavy - Its only job is to wait for the deep pressure to surge, that's it.

Great hydraulic rams will slam shut if the preventer does its job.

The thing is mean enough to shear the drill pipe-in half and kill the well. If you want to pull fire from the deep, this is how they do it-With computers, and a very big knife, cheers.

Which is one of the longest sea beach in world?

 There have been several contenders for the longest sea beach in the world.

1. The longest beach was said to be the one stretching from Adale in Somalia to the Horn of Africa, with a length of over 700 km. But this does not seem to be a long continuous sandy beach. It is a long coastline with rocky cliffs, et, in between.

2. The area containing Terence Bay in Namibia was often thought to be the second longest beach, stretching to 480 km. It is also known as the Skeleton Coast. But there seems to be no verified continuous beach in Namibia that extends to such a long stretch uninterruptedly.

3. The third position is often awarded to the Eucla beach in Australia. It is believed to be 280 km long. But the officially verified uninterrupted single stretch of that beach seems to be only 41.5 km.

So Praia do Cassino beach of Brazil, stretching 254 km or 158 miles from the Rio Grande to the border of Uruguay, seems to be the winner in the competition. It has an uninterrupted sandy beach extending to 254 km. It has also been considered the world's longest sandy beach by the Guinness Book of World Records after examining all other claims.
