Siemens Gamesa Renewable Energy has presented a new record-sized offshore wind turbine named the SG 14-236 DD, which features a rotor diameter of 236 meters (774 ft) and a blade length of 115 meters. The new turbine builds upon the previous 222-meters diameter model, but uses the same technology platform so its production can stay […]
Read MoreUS startup Green Hydrogen International (GHI) has unveiled its plans to build the world’s largest green hydrogen plant. The company is planning to build a 60 GW green hydrogen production facility in South Texas. The project is called Hydrogen City. It will take account of integrated green hydrogen production, storage, and transportation capabilities. The company […]
Read MoreGE Aviation Engine Services Singapore has become the first entity to offer metal additive technology for aerospace components, including aircraft engines. To put this simply, that would be 3D printed metal parts that are custom-crafted to the specific needs of the repair job and embedded or fitted where needed. The idea is to offer custom […]
Read MoreEngineers at the USAF are designing digital twins of older aircraft such as the venerable B-1 Lancer, first introduced almost five decades ago. The heavy bomber and many others of its time were designed on paper blueprints featuring hand-drawn schematics, as the age of computer-assisted design (CAD) hadn’t dawned yet. If you wonder why engineers […]
Read MoreNickel is undergoing a wild pricing ride lately, being one of the most heavily affected metals of the market turbulence caused by the Russian invasion of Ukraine and the resulting sanctions and shortages. The region of Krasnoyarsk in Russia is one of the world’s major production hubs of nickel, so closing that supply tap makes […]
Read MoreResearchers at the Fraunhofer Institute in Germany have developed a novel laser-based system that can be used for precision and energy-efficient welding of construction metals. According to their measurements, the energy requirements of their system are roughly 85% lower than that of conventional welding methods, while the result is also typically of a higher quality […]
Read MoreConcorde was the world’s first supersonic airliner, it entered service in 1976. But the Concorde aircraft was grounded in 2003, three years after the crash of Air France Flight 4590, in which all passengers and crew were killed. But when Concordes were in action, they would often break the sound barrier. Concorde’s window-rattling sonic booms produced enormous sound energy, […]
Read MoreResearchers at the University of Central Florida have developed a new outer shell of layer carbon composite material that acts as an energy exchange medium. To achieve this, the scientists created positively and negatively charged carbon fiber layers and then stacked and attached them in an alternating pattern, essentially forming a supercapacitor. The graphene sheets […]
Read MoreSteelmaking giant ArcelorMittal SA has closed its Ukrainian steel mill on Thursday after facing raw material supply disruptions and increasing risks associated directly with the Russian invasion of the Eastern European country. The company shut down blast furnaces gradually as the supply problems culminated and forced the production to a minimum, but the escalating situation […]
Read MoreScientists at the Nanyang Technological University in Singapore have developed a cost-efficient method to evaluate the quality, physical, and mechanical properties of 3D printed metal parts. This is a very important development for engineers and technicians across all fields, as it could unlock 3D printing technology applications that were previously deemed too risky due to […]
Read MoreA team of researchers at UC Santa Cruz have found a cost-effective and practically feasible way to produce clean hydrogen gas by using water, aluminum, and gallium. Aluminum’s high level of reactivity has been known and well documented for many years, but researchers struggled to find an efficient way to put it into the context […]
Read MoreThe Cornell Fracture group has published the results of an ongoing study on the formation and propagation of fatigue cracks on metals and claims to have identified the mechanism that causes the cracks to grow. Their paper, titled “Atomic Mechanism of Near Threshold Fatigue Crack Growth in Vacuum,” explains that a molecular dislocation happens near […]
Read MoreDoosan Bobcat has presented a new digger and truck loader model codenamed ‘T7X’, and it’s the world’s first fully-electric excavation equipment. The product was presented during the recent 2022 CES, and it won the “Innovation Award” in the category of vehicle intelligence and transportation. The T7X features a 62-kilowatt lithium-ion battery that can keep the […]
Read MoreThe San Giorgio bridge in Genoa, Italy, may not look like anything extraordinary at first sight, and it’s really nothing special when it comes to design and structural ingenuity, yet it’s considered to stand at the cutting edge of technology in the field. The way through which San Giorgio is pushing the envelope lies in […]
Read MoreThe Dutch prosecutors have opened a criminal investigation into Tata Steel for intentional and unlawful pollution, a result of the operation of its Amsterdam-based steelwork facilities. The authorities have also launched a probe involving specialist investigators to determine the scale and type of pollution that is taking place to compare it with the legal emission […]
Read MoreMitsubishi Heavy Industries is developing a new type of nuclear reactor that will adjust its power output in approximately 17 minutes. This is unprecedented in the field as existing reactors need several hours to reach new output targets and stabilize there. The power output of a nuclear reactor is the result of a complex set […]
Read MoreJapan and the United Kingdom plan to work together on a new jet engine for their future sixth-generation fighter aircraft. The work on the jet engine will be led by Mitsubishi Heavy Industries (MHI), IHI from Japan, Rolls-Royce and BAE Systems from the UK. Apart from collaborating on and developing the jet engine, both the […]
Read MoreThe National Institute of Standards and Technology (NIST) and the University of California San Diego have proposed targeted updates to the AISC 341 standard on seismic provisions for structural steel buildings. The specialist engineers have identified certain deficiencies in the performance of steel beams that were otherwise compliant with the existing standard, which caused them […]
Read MoreThe trade union ‘Unite’ is vocally complaining towards the UK government for failing to ensure that the HS2 (High Speed 2) rail project, one of the largest of its kind in Europe, will procure steel made in the country. The HS2 project aspires to connect London and Manchester with a high-speed (400 km/h, 250 mph) […]
Read MoreMIT researchers have developed a new processing method to help retrieve rare metals that are costly to mine and are getting increasingly harder to find. The technique is called “solid selective separation”, and it could replace liquid separation for at least 56 elements, 15 of which have already been tested successfully. Compared to liquid separation, […]
