The offshore wind farm is expected to lower China’s carbon dioxide emissions by 1.36 million tonnes and claims to provide more than 1.6 billion kilowatts of power annually.
China claims to have begun the construction of its first extensive offshore wind farm using 16-megawatt turbines on Saturday.
This represents a significant change from the smaller, less effective turbines that China’s offshore wind farms have often employed, claimed a report on Sunday by China Global Television Network (CGTN), a state-run media.
In a bid to make wood stronger and lighter than glass to move towards an energy-efficient future, a team of researchers at the University of Maryland has found a new way to make wood completely transparent which they believe to be better than the previous techniques.
The paper, published in the journal Science Advances, details the making of their transparent wood which was found to be 50 times stronger than the ones made using the conventional way.
BMW Group will present the first electric drive system for a wingsuit with which the centuries-old dream of flying can be realised in a completely novel way. The innovative drive module and the likewise entirely newly designed wingsuit were developed in a cooperation between BMW i, Designworks and the professional wingsuit pilot Peter Salzmann from Austria. His maiden flight with the Electrified Wingsuit by BMW i was visually captured in an elaborately staged video documentation. The spectacular film, which will be seen for the first time in the run-up to the #NEXTGen 2020, shows impressively how BMW eDrive technology is able to make a lasting change to the individual mobility experience.
The long-term experience and the BMW i brand’s pooled development competence have now been utilised in a completely innovative way. The result is an extremely powerful, compact and light drive and energy storage package for a unique flying experience with the Electrified Wingsuit by BMW i. The fly unit of the Electrified Wingsuit by BMW i comprises two encased carbon propellers, so-called impellers, each delivering a power output of 7.5 kW, a speed of around 25,000 rpm and a total output of 15 kW, which is available for approximately 5 minutes. The design of the drive unit and the likewise exclusively developed wingsuit is the result of a cooperation between Peter Salzmann and the creative team from Designworks. The BMW Group subsidiary has strongly influenced the BMW i brand’s design from the outset, applying its creative capabilities not only in the automotive sector, but also on behalf of numerous international clients from other branches of industry.
Around 3 years passed from the idea of a wingsuit flight with electric extra boost to the premiere in the Austrian alps. During this time the air sports pioneer Peter Salzmann and his partners at BMW i and Designworks worked jointly on the details of the suit and the drive system. The electric twin-propeller drive system including an energy storage unit were perfectly integrated into the front of the wing suit. The tests in the wind tunnel at the BMW Group Aerodynamics Testing Centre in Munich were a significant part of the development programme for the project.
Researchers at UCL and the University of Cambridge have discovered a new type of ice that more closely resembles liquid water than any other known ices and that may rewrite our understanding of water and its many anomalies.
The newly discovered ice is amorphous—that is, its molecules are in a disorganized form, not neatly ordered as they are in ordinary, crystalline ice. Amorphous ice, although rare on Earth, is the main type of ice found in space. That is because in the colder environment of space, ice does not have enough thermal energy to form crystals.
For the study, published in the journal Science, the research team used a process called ball milling, vigorously shaking ordinary ice together with steel balls in a jar cooled to-200 degrees Centigrade.
Today’s world is facing large-scale problems, from wars to water shortages to a looming global recession. It’s not easy to accurately conceptualize the risks posed by these issues. This is especially true when people on social media or in the news inaccurately overblow certain problems and discount others, or when problems become so emotionally or politically charged that it seems impossible to work toward a solution.
That’s one reason why the Eurasia Group publishes a detailed analysis of the top risks facing our world each year. As political scientist Ian Bremmer explains, the top risks for 2023 include water stress, inflation shockwaves, and the uncertain future of a “rogue Russia.”
Seqenenre Tao was the pharaoh who ruled southern Egypt in the late 17th dynasty, roughly between 1,558 and 1,553 BC.
That was a troubled time. The Hyksos (whose name in ancient Egyptian was Heqau-khasut, “the rulers of foreign lands”) occupied the northern part of Egypt and took Avaris (present-day Tell el Dabaa) as their capital during a time called the “second intermediate period” (1650−1550 BC).
Although the pharaohs maintained power over the south (with capital in Thebes), the entire territory was forced to pay tribute to the invaders.
Nanoscale defects and mechanical stress cause the failure of solid electrolytes.
A group of researchers has claimed to have found the cause of the recurring short-circuiting issues of lithium metal batteries with solid electrolytes. The team, which consists of members from Stanford University and SLAC National Accelerator Laboratory, aims to further the battery technology, which is lightweight, inflammable, energy-dense, and offers quick-charge capabilities. Such a long-lasting solution can help to overcome the barriers when it comes to the adoption of electric vehicles around the world.

According to the team, the issue was down to mechanical stress, which was induced while recharging the batteries. “Just modest indentation, bending or twisting of the batteries can cause nanoscopic issues in the materials to open and lithium to intrude into the solid electrolyte causing it to short circuit,” explained William Chueh, senior study author and an associate professor at Stanford Doerr School of Sustainability.
