Meet BMW Electric Wingsuit — the future of individual flying is now
Posted by Omuterema Akhahenda in categories: energy, transportation
This is the BMW electric wingsuit 2021.
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.

Discovery of new ice may change our understanding of water
Posted by Saúl Morales Rodriguéz in categories: energy, space
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.

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.

Scientists solved mystery to make next-gen lithium batteries
Posted by Gemechu Taye in categories: energy, nanotechnology, sustainability, transportation
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.

High-Power Laser Creates a Miniature Magnetosphere

Year 2022, this basically could shield the earth or Mars from solar radiation if we needed it. 😗
First experimental measurement of pure electron outflows associated with magnetic reconnection driven by electron dynamics in laser-produced plasmas.
Magnetic reconnections in laser-produced plasmas have been investigated in order to better understand the microscopic electron dynamics, which are relevant to space and astrophysical phenomena. Osaka University scientists, in collaboration with researchers at the National Institute for Fusion Science and other universities, have reported the direct measurements of pure electron outflows relevant to magnetic reconnection using a high-power laser, Gekko XII, at the Institute of Laser Engineering, Osaka University in Japan. Their findings will be published today (June 30, 2022) in Springer Nature, Scientific Reports.

Air Waveguide from “Donut” Laser Beams
Posted by Saúl Morales Rodriguéz in category: energy
A waveguide sculpted in air with lasers transmits light over a distance of nearly 50 meters, which is 60 times farther than previous air-waveguide schemes.
Conventional optical waveguides such as optical fibers and planar waveguides consist of a core surrounded by a cladding with a lower index of refraction. Light is efficiently confined in the core by total internal reflection at the core-cladding boundary. Optical fibers can transport light over 100s of kilometers, but there are applications—such as high-power transmission and atmospheric monitoring—where the use of fibers becomes impractical. Sending light directly through air is not an option, as diffraction effects cause the beam to spread out. A potential solution is to “sculpt” waveguides in the air with laser pulses that produce a low-density cladding around a central core of unperturbed air. Using a new method with donut-shaped beams, Andrew Goffin from the University of Maryland, College Park, and colleagues have created a 45-m-long waveguide in air [1], reaching 60 times farther than the record they previously established for an air waveguide.
