Li-Cycle, Northvolt, and Ganfeng Lithium are among those building recycling plants, spurred by environmental and supply-chain concerns.
The Giant Magellan Telescope will be one of the few super giant earth-based telescopes that promises to revolutionize our view and understanding of the universe. It will be constructed at the Las Campanas Observatory in Chile. Commissioning of the telescope is scheduled to begin in 2021.
The GMT is a segmented mirror telescope that employs seven of today’s largest stiff monolithic mirrors as segments. Six off-axis 8.4 meter segments surround a central on-axis segment, forming a single optical surface 24.5 meters in diameter, with a total collecting area of 368 square meters. Harvard University and the Smithsonian Institution are both members of the GMT project, which also includes Astronomy Australia Ltd., the Australian National University, the Carnegie Institution for Science, the Korea Astronomy and Space Science Institute, the São Paulo Research Foundation, the University of Texas at Austin, Texas A&M University, the University of Arizona, and the University of Chicago.
Airspeeder wants to be the “first electric flying car race,” its CEO told Insider. It also wants you to know flying cars are closer than you think.
An Edinburgh company that generates electricity from gravity — is getting noticed by investors, as an effective alternative to large batteries, so that renewable energy supply can be stored until there is demand. No need to go to the Congolese jungle to get hold of the raw materials for batteries.
The U.S. Air Force is planning to put its futuristic flying car through a series of tests next year that will help determine how the service can use the vehicle, at home or deployed.
The M2-F1: ‘Look Ma! No Wings!’
Posted in space travel
The end of the space shuttle program concluded an era that began almost a half century earlier with the first free flight of a wingless lifting body.
In the coming years, NASA’s Project Artemis will send astronauts to the Moon for the first time in fifty years. In the years that follow, NASA and the European Space Agency (ESA) also hope to build a spiritual successor to the ISS – the international lunar village around the Moon’s southern pole.
With multiple space agencies looking to build bases and private aerospace companies like SpaceX and Blue Origin hoping to make lunar tourism a reality, the message is clear: We’re going back to the Moon. And this time, we plan on staying!
But what about the long-term? What about a lunar colony where us regular folk can live, work, and become the first “Selenians” (or “Lunites”, “Lunarians”, “Loonies”, etc.). It’s been explored extensively in science fiction, but how about for real? Could it be done?
“The process of creating methane-based fuel has been theorized before, initially by Elon Musk and Space X. It utilized a solar infrastructure to generate electricity, resulting in the electrolysis of carbon dioxide, which, when mixed with water from the ice found on Mars, produces methane. This process, known as the Sabatier process, is used on the International Space Station to produce breathable oxygen from water. One of the main issues with the Sabatier process is that it is a two-stage procedure requiring large faculties to operate efficiently. The method developed by Xin and his team will use anatomically dispersed zinc to act as a synthetic enzyme, catalyzing the carbon dioxide and initializing the process. This will require much less space and can efficiently produce methane using materials and under conditions similar to those found on the surface of Mars.”
Among the many challenges with a Mars voyage, one of the most pressing is: How can you get enough fuel for the spacecraft to fly back to Earth?
Houlin Xin, an assistant professor in physics & astronomy, may have found a solution.
He and his team have discovered a more efficient way of creating methane-based rocket fuel theoretically on the surface of Mars, which can make the return trip all more feasible.
Oak Ridge National Laboratory’s Center for Nanophase Materials Sciences, or CNMS, contributed to a groundbreaking experiment published in Science that tracks the real-time transport of individual molecules.
A team led by the University of Graz, Austria, used unique four-probe scanning tunneling microscopy, or STM, to move a single molecule between two independent probes and observe it disappear from one point and instantaneously reappear at the other.
The STM, made available via the CNMS user program, operates under an applied voltage, scanning material surfaces with a sharp probe that can move atoms and molecules by nudging them a few nanometers at a time. This instrument made it possible to send and receive dibromoterfluorene molecules 150 nanometers across a silver surface with unprecedented control.
“Klein tunnelling” has been observed directly for the first time.
A curious effect called “Klein tunnelling” has been observed for the first time in an experiment involving sound waves in a phononic crystal. As well as confirming the century-old prediction that relativistic particles (those travelling at speeds approaching the speed of light) can pass through an energy barrier with 100% transmission, the research done in China and the US could lead to better sonar and ultrasound imaging.
Quantum tunnelling refers to the ability of a particle to pass through a potential-energy barrier, despite having insufficient energy to cross if the system is described by classical physics. Tunnelling is a result of wave–particle duality in quantum mechanics, whereby the wave function of a particle extends into and beyond a barrier.
Normally, the probability that tunnelling will occur is less than 100% and decreases exponentially as the height and width of the barrier increase. However, in 1929 the Swedish physicist Oskar Klein calculated that an electron travelling at near the speed of light will tunnel through a barrier with 100% certainty – regardless of the height and width of the barrier.
