  • I've covered a lot of people's crazy ideas in the past.


  • On this channel, there was the plan to drain the Mediterranean Sea, the plan to nuke a hole in the ground to create a new C and several other lunatic things.


  • But sometimes an idea is so insane that it causes you to seriously wonder who on earth came up with it.


  • Enter the man Jeffrey Pyke and his wild idea during the Second World War to build a freaking aircraft carrier out of ice.


  • While that doesn't immediately seem to make any reasonable sense, allow me to explain why it sort of did at the time.


  • One of the biggest problems that Britain was facing in 1941 in 1942 was the fact that German U boats in the Atlantic were singing huge amounts of allied cargo and shipping.


  • Britain's greatest advantage and disadvantage during the war was the same thing.


  • They were located on an island.


  • This helped to prevent a German land invasion from happening in 1940 but it also meant that all of their imports from other countries had to be coming in by ship.


  • And if the Germans could sink enough of it, it might mean that Britain would starve.

    而如果德國人能擊沉足夠多的它, 它可能意味著英國會餓死。

  • This map here shows every single allied ship that was sunk by German U boat activity during 1941 and you can see a pattern emerging when you take into consideration the range that the Royal Air Force could operate in.


  • Represented by these arcs.


  • A huge zone of the Atlantic was simply out of range for any planes in the R A F, taking off from bases on land to reach and defend.

    大西洋的一大片區域根本不在R A F的任何飛機的飛行範圍內,從陸地上的基地起飛才能到達和防守。

  • And so this zone was where most Allied shipping was sunk, and it came to be known as the Mid Atlantic Gap.

    所以這個區域是大多數盟軍船艦被擊沉的地方, 而它後來被稱為大西洋中峽。

  • The Royal Navy couldn't simply produce more aircraft carriers to patrol the area during wartime because the steel needed to create those ships was required for other, more critical purposes, like guns, tanks, bombs and planes.


  • And so, in 1942 Jeffrey Pyke believed that he had come up with a solution.


  • While steel may have been in critically short supply for Britain during the war to things that weren't, where would and ice Pike began studying icebergs and thought, Hey, you know what would be cool?


  • What if we took one and shaved off the top to create a runway, dug out the center to create a hanger to put planes in, and then dropped into the middle of the Atlantic before it melted?

    如果我們把其中的一個削掉頂上的部分做成跑道 挖出中間的部分做成飛機庫 然後在它融化前掉進大西洋中間呢?

  • There were a few problems with Pike's Ice Death Star idea, though namely, that icebergs are way too small for that.


  • Most of an iceberg is underwater anyway, and probably worst Icebergs sometimes randomly tip over, which wouldn't be a 100% ideal situation.


  • But what if, instead of taking an iceberg from nature, they created their own iceberg and made it look like a ship or aircraft carrier?


  • Three idea was born in 1942 but creating a ship out of pure ice wouldn't too, because, well, ice is ice, and it has a bad tendency to melt into sync.


  • So instead, pike in, a team of scientists developed a new material specifically for the ship that they called Pie Crete, basically just a mixture of water, ice and wood pulp that wouldn't sink and significantly enhanced the strength and the melting time of ice as a material, one ton of ice only requires 1% of the energy needed to produce one ton of steel.


  • So in theory, it should have been a lot cheaper to construct the whole carrier from Pike Rate than from steel.


  • But in practice, that wasn't exactly how it would turn out.


  • Starting in 1943 the British created a small ish prototype of the Burgh ship on a lake in Canada that was 18 by 9 m wide and weighed 1000 tons.


  • The full plan, however, called for the creation of the largest ship that would have ever been created.


  • Dubbed Project Have a Cock, the full ship was supposed to be 1.2 kilometers long by 180 m wide, which is unbelievably, stupidly huge for reference.

    被稱為 "有公雞計劃",全船應該是1.2公里長,180米寬,這簡直是不可思議,愚蠢的巨大,供參考。

  • That's a boat that's bigger than some countries.


  • Here is the ship placed over top of Vatican City.


  • Here is the tallest building in the world place next to it, and here is the actual biggest ship ever created.


  • Placed next to it, it was absolute lunacy, but even mawr insanely, they thought they could construct one for only 700 £1000 which is only about £31.3 million today.


  • For further reference, just one Queen Elizabeth class carrier in the current Royal Navy cost about £3 billion.


  • It was calculated that the amount of wood pulp needed to produce a carrier this massive would have had a serious effect on the Allied supply of paper during the war.


  • While the pie create material itself was proving to be fairly tricky toe work with in order to prove how durable of a material pie Crete actually was apparently an admiral brought to different blocks with him to a convention in 1943 Quebec with Churchill and Roosevelt present.


  • One block was normal ice, while the other was Pie Crete.


  • The admiral pulled out his pistol, shot and shattered the ice block, then turned and shot the Pie Crete block and experience the bullet bounce off and ricocheted and grazed another admiral present across his leg.


  • Needless to say, pie Crete was much tougher than regular ice waas, but it's still suffered from other similar physical properties, namely cold flow, where the tendency of ice to sag the prototype ship in Canada was sagging, which meant that more steel reinforcements were needed than previously thought, and more effective insulation was needed around the ship's hole to prevent everything inside from melting even further if the full model ship was ever actually built steam Turbo generators on board, we're going to provide 26 external electric motors around the ship's hole with 33 1000 horsepower.


  • The motors couldn't be placed inside the ship because of all the heat that they would be producing, while a massive refrigeration plant would be located somewhere inside.


  • Instead, that would keep the interior just nice and freezing.


  • All of the crew on board would be literally living and working inside of these freezing conditions for months on end, like they were basically in the Arctic, 150 total planes divided between bombers and fighters could be stored on board the ship and made ready for takeoff, while the surface would be equipped with dozens of anti air guns and small cannons.


  • However, all of this extra steel required for the refrigeration plant bracing and installation of a ship of this ridge ridiculous size was beginning to appear to be stupidly impractical.


  • Obviously, according Toa one American study, the amount of steel required by a 1.2 kilometer long ice ship would b'more than the steel required to build an entire fleet of conventional aircraft carriers, which kind of defeated the entire purpose of it in the first place to save steel.


  • And by 1944 a lot of other things were happening that basically killed the hobby Cook iceberg ship anyway.


  • First, Portugal decided to open up their airfields toe allied planes in the resource which greatly extended Allied range out into the Atlantic.

    首先,葡萄牙決定向資源中的盟軍飛機開放他們的機場 這極大地將盟軍的航程擴大到大西洋。

  • Second, longer range fuel tanks were allowing British planes to fly for longer and further out into the Atlantic anyway.


  • And third, and probably most importantly, the Americans were starting to get heavily involved in the Atlantic.


  • And we're introducing their own escort carriers.


  • All of these factors combined made creating a kilometer long ice ship looked like the stupid idea that it really waas on idea made out of desperation rather than an idea made out of cold science.


  • If you think you can design a better ice ship, you'll need a pretty firm grasp on things like physics, classical mechanics, water flow, displacement, thermodynamics and mawr and all of those things you can learn on brilliant dot or GTA.
