So the small workbench with the vents has the effect of dissipating heat for the machine. It will be even more perfect if the heat sink is in line with the laptop’s vent.

According to Business Insider, a video clip recently released by Gravity Industries (UK) shows soldiers of the Royal Marines wearing a Jet Suit personal jet produced by this company. disembarking from the speedboat, ascending, and rapidly landing on the deck of the Royal Navy’s offshore patrol vessel HMS Tamar. In the video, British soldiers fly easily over the sea like the superhero character Iron Man (Iron Man) in the famous Hollywood movie of the same name. The Jet Suit personal jet suit helps the wearer move easily through the air. Photo: CNN The exercise was conducted to explore how to land on ships as an alternative to the traditional method. In a statement, the Royal Navy said the Royal Marines used the Jet Suit to practice the “visit, board, search and capture” (VBSS) operation. VBSS is considered one of the most complex and dangerous sea missions. Traditionally, soldiers would use speedboats to approach warships and use rope ladders to climb or conduct landings from helicopters with the support of snipers and drones. Both of these methods require a lot of time to prepare the means. Meanwhile, with a personal jet suit, a soldier can fly up from a speedboat, land on a ship and then release a rope ladder for teammates to climb onto the ship. The images in the video clip show the Jet Suit’s ability to support soldiers on landing missions on board ships. “The Jet Suit provides extremely rapid access to any area of ​​the target ship, making it convenient for soldiers to carry weapons and easily move or retreat,” said Gravity Industries. . This is a tactical revolution for many special forces and can be applied more widely than just landing on ships.” With an operation time of 8 minutes, the Jet Suit personal jet made by Gravity Industries is equipped with 5 mini jet engines, including 4 engines attached to the arms and one on the back. Thanks to this design, the user can easily adjust the flight direction as desired. After wearing the Jet Suit, the user can fly at speeds up to 88km/h. This technology is a big step forward in making scenes from sci-fi movies come to life. British inventor Richard Browning, founder of Gravity Industries and a former member of the British Royal Marines, has worn Jet Suits to show the world many times and has been dubbed “Real-life Iron Man real”. Commenting on the Moskovsky Komsomolets newspaper, Russian military expert Vladimir Gundarov said that, like the supporting skeleton or invisibility cloak, personal jet suits will not be widely used in military units. . “All special equipment will be provided to the special forces and can be used in an emergency,” said Vladimir Gundarov. Besides the obvious advantages, Boris Gundarov said that personal jet suits also have disadvantages such as the lack of stealth, jet engines emitting a lot of noise and emitting a lot of heat. A person flying in the air with a personal jet suit is an easy target for any weapon, the expert notes. It is not clear how effective the Jet Suit will be if used on the battlefield, but it is clear that this personal jet suit will need to be improved to overcome some disadvantages that can endanger soldiers. as well as extending the operation time to match combat operations.

Halfway up Phja Mon mountain (circled), where the ancient coffin is located. PHOTO: Duy Chien Deadly According to the police report of Van Lang district, Lang Son province, around 9 a.m., on October 15, 2017, local authorities discovered a ladder rope about 60 meters long made of blue synthetic fiber, bamboo slats. with two-headed iron pipes hanging from the middle of the cliff of Phja Mon mountain to National Highway 4A, in the area of ​​​​zone 5, Na Sam town, Van Lang district.

From the mouth of the cave, there is a stone mound about 1m high, blocking the entrance of the cave. In the cave, there are many compartments (subjects have explored 3 compartments). The first compartment is about 60m2 wide (10m long, 6m wide). In the middle of the first chamber on the right, there is a small path going up, to a parallel 60m2 wide cave, higher than the first cave.

The wooden coffins are arranged in 2 rows in the style of terraced fields, some of the coffins have been broken (in this compartment there is no altar, no incense bowl, writing on the cave wall). The group of people were quietly following a small path to continue searching for gold and silver, when they stopped, did not dare to continue, and quickly left the scene because in the dark there was the shadow of a giant animal, the shape of a giant animal. like a python blocking the road. “After the incident, it was reported that the Chinese came to the locality to continue to explore precious minerals hidden in Phja Mon cave. Through investigation, it was a false rumor, in which there was no wealth, gold or silver,” Colonel Bang affirmed. The coffin was buried in the mountain (photo provided by Lang Son Museum) “Heavenly Burial” Mr. Nong Duc Kien, Director of Lang Son Provincial Museum, said that after receiving the information, specialized agencies have entered the investigation. According to photos and documents provided by authorities and people, the coffins are now not intact, most of them have been broken open (maybe because some people had previously entered to find antiques). . The coffin is made of a large wooden trunk split into two equal parts, in the middle is cut in the shape of a trough to place the body, then close to each other) with keyholes at both ends that are locked with wedges. The coffin is about 1m long, 0.4m in diameter (many are broken and rotten). There are no carved patterns on the coffin. The coffin is arranged in two rows facing up in the style of terraced fields located close to the cave wall, inside there are human bones. “This is a rather unique form of ancient burial in a cave. The dead are not buried but buried in a cave, the coffin is made of tree trunks, crafted quite delicately, shaped like a small canoe, expressed through the technique of opening the heart and latching the coffin quite similar to The coffin was discovered at Keo Lam cave in Lung Phay village, Chi Minh commune, Trang Dinh district, Lang Son in 2016. Based on the specimen, it is possible that this artifact was about 300-400 years ago. ” Mr. Kien said. “The form of ancient burial is quite unique in the cave, in Vietnam, it has only been discovered in three provinces of Thanh Hoa, Son La, and Lang Son.” He Nong Duc Kien ,Director of Lang Son Museum According to Mr. Kien, the discovery of graves at Phja Mon cave are important historical documents, contributing to scientific research for archaeologists, ethnographers, in many fields of history and human history. race, creed. Through it, we can lift the mysterious veil of the ancient tomb, sketching out the economic and social situation of the ethnic people of Lang in ancient times. Mr. Kien said, on April 23, 2021, the survey team including leaders of the cultural industry, the Museum and the People’s Committee of Van Lang district came to the scene. However, because the road to Phja Mon cave is very difficult, having to use a climbing ladder from the top of the mountain is very dangerous and unsafe, and on this occasion the COVID-19 epidemic broke out again, so the work must be done. stop. “We are thinking of hiring an expedition team with specialized machinery to go into the cave to collect artifacts for research. But in the immediate future, in order to manage and protect the artifacts in their original state, it is recommended that local authorities at all levels step up propaganda work and take measures to protect the integrity of antiques,” said Mr. Kien.
