In 1845, John Franklin’s expedition set sail in search of the Northwest Passage. 180 years later his loss remains a mystery

On the morning of May 19, 1845, Captain John Franklin and his expedition weighed anchor from the Greenhithe Harboralmost at the mouth of the Thames. They were looking for the Northwest Passagethe (at that time theoretical) maritime route that would link the Atlantic and the Pacific through northern Canada. They never came home. 129 men who never returned and who, for 170 years, have been one of the great questions of scientific and naval exploration. We now know why the men of John Franklin’s lost exploration died. There are those who insinuate that the trip started badly from the beginning. It should never have been in the first place. John Franklin. The first option William Edward Parryone of the great English explorers, but he had already traveled to the Arctic five times and “was tired.” So he declined the offer. Secondly, they thought about James Clark Ross. Ross has just arrived from Antarctica where he had explored the Ross Sea and Island. In fact, the ships on that expedition were the same as those that would be used on this mission (two of Ross Island volcanoes They are called Erebus and Terror in honor of the ships). But upon returning to England, he became engaged to his future wife and decided that great explorations were no longer for him. He was followed by James Fitzjames (discarded due to inexperience), George Back (considered too controversial) and Francis Crozier (who, well, was Irish and that was more than enough reason to rule him out). Seeing the yard, John Barrow, second secretary of the Admiralty, called John Franklin. To this day no one knows why Franklin, who was already a legend at the time and was almost 60 years old, he said yes. But the fact is that, as I said, they left the vicinity of London that day in 1845. They stopped in Orkney and the convoy formed by the two main ships (HMS Erebus and HMS Terror), the HMS Rattler (the first English warship with steam propulsion) and a transport headed to Greenland. There they sacrificed ten oxen and the expedition began its solo journey. The search for the Northwest Passage The travels of Marco Polo are a peculiar book. Not only does it remain a very interesting precedent for current anthropology, but it served as an inspiration for many during the era of great exploration. The image you can see above is precisely the annotated copy of ‘The Voyages’ that Christopher Columbus had. In one of its versions, the Italian one from 1559, a Chinese province called Anian. We assume that it was from there that the geographers and explorers who discussed whether America was a new continent or, on the contrary, an Asian peninsula, got the name of the Strait of Anian, the separation between Asia and America that would give access to the Northwest Passage. It is what we know today as the Bering Strait and for years it was pure mythology. But, first, Ferdinand Magellan and his crew turned around Cape Espiritu Santo and found themselves face to face with the southeastern passage; and, second, a Dane in the service of Russia, Vitus Beringrediscovered for the West the strait through which Semyon Dezhniov had already traveled sixty years before. The rest was geopolitics: the quick passage to the Pacific without having to pass near the Spanish territories in America was too juicy. In 1745, an English law promised 20,000 pounds to whoever discovered the pass and the boom began. I have tried to convert the amount to a current currency and I have not been able to do it accurately, but I have drawn one conclusion: it was a lot of money. Favorable weather In early August 1845, two whalers, the Prince of Wales and the Enterprise, encountered Franklin’s ships in Baffin Bay. They were waiting for favorable weather to enter the Strait of Lancaster. That was the last time they were seen. Two years passed. And, little by little, Lady Jane Franklin, some members of Parliament, and the fledgling British press began to ask the Admiralty to send someone to search for the heroes of Franklin’s expedition. The Government sent three expeditions: one by land and two by sea, one through the Atlantic and another through the Pacific. They failed. Fearing that they would be forgotten, Lady Jane Franklin composed her lament, the song you can hear just above. And, although I don’t know if it was for that reason, the truth is that was not forgotten. In fact, the search for the lost expedition “became nothing less than a crusade.” In 1850 alone, eleven British and two American ships tried to locate them. It was then that the first tombs were found. Over the years, the different expeditions found fragments, Inuit stories and objects from the expedition. In 1855, following the indications of some Inuit tribes, pieces of wood were found with the name of Erebus. In 59 two messages were found. The first, dated May 28, 1847, was from Franklin himself and read “Sir John Franklin, Commander of the Expedition: All Well.” It is the document on the right. It was a common practice at the time, documents were left in different places so that, in case of problems, they could be reconstruct the details of the trip. But in this case, something curious happened: on the edges there was another message, dated April 25, 1848, explaining that the ships had been trapped in the ice. Franklin and twenty-three other crew members were dead. And the rest, the survivors, had abandoned the ships looking for an exit to the south. In the next few years some objects, some rumors and some tombs appeared. Nothing else. The ships never appeared and we never, in 150 years, discovered what had really happened to Captain John Franklin’s lost expedition. One hundred and fifty years without news In the 1980s, the University of Alberta launched a project to track the expedition. The different possible routes were traveled … Read more

China has ships the size of buildings that sail on mountains. All thanks to the largest elevators in the world

China is the cradle of record mega -structures. They build in all dimensions (they have unnoticing skyscrapers in the world and deeper oil well) and, on many occasions, they are extremely complicated works, such as the Gaoligongshan tunnel or that of Huajiang Great Canyon Bridge. Something that also abounds in China are pharaonic dams, being the Three throats The biggest in the world. And something that these dams need are elevators, but not for people: for ships. And the elevator systems of both dams are so imposing that they allow ships of up to 3,000 tons to “sail” through the sky. The classic solution. There are dams and prey. When one of these structures is built, the river navigation flow. Sometimes, it doesn’t matter too much because that river was not a key communication route for trade, but other times it is necessary to devise a solution to have a prey without interfering in the activity of the ships. The solution is the one used in channels like Panama or Suez: huge and sealed cameras that are filled with water when a ship enters so that it can overcome the unevenness and continue its path. Or vice versa when you want to “go down.” The problem is that it is a system that requires a lot of time and transit is resent. And the revolution. The solution to this? Elevator systems such as those we use daily, but for ships. A close example is that of the Falkirk wheel in Scotlanda rotating elevator with a combined capacity of 600 tons that allows the barges of the channel to follow its course. Each of the drawers has the capacity for two ships up to 20 meters in length and seeing it in operation is most curious because it is like a fair attraction: Now, as we say: 20 meters of length is the maximum and 600 tons is not so much weight. They are the dimensions for passenger ships that navigate a channel, but China needed the Commercial ship traffic He did not stop at two of his great dams. And the solution they found is the one we used to see in the country’s constructions: bombastic elevators. Before the elevator (in the most focused part), in the dam of the three throats there was only one system of locks The three throats. The three throats dam is imposing in every way. Located on the Yangtsé River, it has an installed power of 22,500 MW for hydroelectric energyhas a height of about 185 meters and a total length of 2,335 meters. It is the Great Chinese Aquatic Wall. To maintain an annual traffic of almost 30,000 ships, including Cruises and Portenerosomething had to be done, and in 2016 they finished the Huge elevator. It is a vertical elevator that is how we imagine that it should be an elevator for ships: a huge bathtub of 120 meters long and 18 wide, tens of steel cables and a powerful pulley system that have the ability to displace ships up to 3,000 tons. The total lifting weight, including chamber and water, is 15,500 tons. It covers 113 meters high and, three hours of total journey, it is passed to about 40 minutes. It is something that is sought to expand to increase the movement capacity of 18 ships daily to a larger amount and here you have it in operation: That of the Goupitan dam. Now, although imposing due to its dimensions and load capacity, its design is more functional than aesthetic. However, the elevator system of the Goupitan dam It is another song. Located on the WU River, which is a tributary of Yangtsé, has a length of 430 meters and a height of 232 meters. It stands out not so much for its installed energy capacity of 3,000 MW, but for its channel -shaped elevators system. Unlike the three throats, to save the unevenness caused by the dam, engineers devised a system of three vertical elevators connected by channels. The maximum boat capacity is 500 tons and the camera is much smaller (40 x 12 meters), but the relevant is the total height of those 199 meters that save the ships. And the times? About two hours in total for the entire route, but its design channel design reduces bottlenecks. Tourist point. The system of channels and elevators of the Goupitan dam ended in 2021 and was a technical headache by connecting several small elevators with each other, as well as a system of channels that, in some case, surrounds one of the mountains. It was a way to demonstrate the technical capacities of the country, but it has also become a tourist point that goes viral in networks due to how attractive it is to see a ship sailing on the mountains. And, although the elevator of the three throats can be boring, it is also a tourist claim, with cruises that include the elevator on your route. Australia, heat what you go out. But, if something is teaching us the Battle of the towers between Saudi Arabia and Arab Emirateswe are in a constant search to overcome ourselves when we talk about megaconstructions, and it is already under construction that will be the new largest stocks for ships in the world, at least by weight: the Darwin Ship Lift Facity. It will be in Australia and it will be an elevator 103 meters long, 26 wide and capacity for vessels of up to 5,500 tons. It is designed to serve fishing vehicles, cruises, border defense, energy and container. Now, the distance to save is just … six meters. Much less impressive than the other great elevators that are worldwide because it will be a maintenance platform, not something to save a height between two sections of a river.

Desperate to find his stolen motorcycle, he ended up locating a container with another 25 about to sail. It wasn’t thanks to GPS

In Spain a motorcycle is steal every six minutes. It is enough with a van and two or three people willing to make it disappear. It is not the only country that this scourge suffers. In the United Kingdom Motorcycles are stolen worth three million each monthsomething that leads to a curious story. One in which the London police could find much more than he was looking for. Biketrac It is a company specialized in GPS tracking devices based in the United Kingdom. Next to the police, and after investigating the theft of a client, he has been able to locate many more motorcycles than he had planned. One of the company’s clients called those responsible for the service, desperate after the theft of their BMW R 1200 GSone of the stars in the German house. Biketrac, which offers a tracking service by combining both GPS and radiofrequency, located the motorcycle at a point of Essexa small county that may sound to you if you like Viking history. They soon realized that the motorcycle was still moving, getting closer and more to a load spring near the port. They were quite clear that thieves wanted to send the motorcycle abroad, and that time ran against him. According to the company, the authorities could be indicated to the exact container that contained them thanks to the radio frequency, and not to the GPS. Within a container, GPS ceases to be a precise technologyand that is where the radiofrequency You can emit small radio pulses that, tracked with appropriate portable receptors, can determine locations exactly. Simply approach the container and check the signal intensity. When it reaches its maximum, you are facing it. With the police authorization, readings were taken in the area to triangular the exact position of the container, identifying its corresponding number to subsequently inform the authorities. Location and number in hand, the police requested permission from the port to access the container. Bingo. Inside it was not alone the BMW R 1200 GS, there were a total of 25 motorcycles stacked in the container, ready to leave the country. This was how, in the task of finding a single motorcycle, almost thirty of them, thanks to radio frequency technology. An unusual in most trackers sold in Spain.
