The floating energy generator is an ideal energy solution for tropical islands that have conventionally relied on fossil fuels for their energy needs.
Droughts led to a drop in generation from hydroelectric plants, and fossil fuels filled the gap.
The ice-covered Jovian moon generates 1,000 tons of oxygen every 24 hours – enough to keep a million humans breathing for a day.
Scientists with NASA ’s Juno mission to Jupiter have calculated the rate of oxygen being produced at the Jovian moon Europa to be substantially less than most previous studies. Published on March 4 in Nature Astronomy, the findings were derived by measuring hydrogen outgassing from the icy moon’s surface using data collected by the spacecraft’s Jovian Auroral Distributions Experiment (JADE) instrument.
The paper’s authors estimate the amount of oxygen produced to be around 26 pounds every second (12 kilograms per second). Previous estimates range from a few pounds to over 2,000 pounds per second (over 1,000 kilograms per second). Scientists believe that some of the oxygen produced in this manner could work its way into the moon’s subsurface ocean as a possible source of metabolic energy.
Toyota is boosting its ability to mass-produce “a wide variety” of EV batteries following an agreement with Panasonic to take full control of Primearth EV Energy (PEVE). The move will help Toyota respond to the growing demand for batteries.
The automaker agreed with Panasonic to make Primearth EV Energy a wholly owned subsidiary Tuesday.
Toyota said the acquisition will strengthen its ability to mass produce EV batteries. It is officially scheduled for later this month.
Playing a different soundtrack is, physically speaking, only a minute change of the vibration spectrum, yet its impact on a dance floor is dramatic. People long for this tiny trigger, and as a salsa changes to a tango completely different collective patterns emerge.
Electrons in metals tend to show only one behavior at zero temperature, when all kinetic energy is quenched. One needs to frustrate the electronic interaction to break the dominance of one particular electronic order and allow multiple possible configurations. Recent results published in Nature Physics on kagome nets suggest that this triangular lattice is quite effective at doing so.
Named after the Japanese bamboo-basket woven pattern, a two-dimensional (2D) kagome lattice is constructed by a series of corner-sharing triangles. When each corner is occupied with magnetic moments with antiferromagnetic correlations, the nearest-neighbor interactions favor anti-aligned spins.
Scientists have revealed why some white dwarfs mysteriously stop cooling—changing ideas on just how old stars really are and what happens to them when they die.
White dwarf stars are universally believed to be ‘dead stars’ that continuously cool down over time. However, in 2019, data from the European Space Agency’s (ESA’s) Gaia satellite discovered a population of white dwarf stars that have stopped cooling for more than eight billion years. This suggested that some white dwarfs can generate significant extra energy, at odds with the classical ‘dead star’ picture, and astronomers initially were not sure how this could happen.
Today, new research published in Nature, led by Dr. Antoine Bédard from the University of Warwick and Dr. Simon Blouin from the University of Victoria (Canada), unveils the mechanism behind this baffling observation.
A new study by researchers at Lanzhou University and Hubei University proposes a quantum battery (QB) charging scheme based on a rectangular hollow metal waveguide. This approach allows them to overcome environment-induced decoherence and charging distance limitations. The findings are published in Physical Review Letters.
The demand and supply for batteries continue to grow with a focus on enhancing energy storage, longevity, and charging capabilities. On this front, scientists are now developing quantum batteries that leverage principles of quantum mechanics to store and supply energy.
The aim is to use fundamental principles of quantum mechanics such as entanglement and coherence to overcome the constraints of classical physics, thereby achieving stronger charging power, higher charging capacity, and larger work extraction compared to classical counterparts.
New phased-array transmitter design overcomes common problems of CMOS technology in the 300 GHz band, as reported by scientists from Tokyo Tech. Thanks to its remarkable area efficiency, low power consumption, and high data rate, the proposed transmitter could pave the way to many technological applications in the 300 GHz band, including body and cell monitoring, radar, 6G wireless communications, and terahertz sensors.
Today, most frequencies above the 250 GHz mark remain unallocated.
Accordingly, many researchers are developing 300 GHz transmitters/receivers to capitalize on the low atmospheric absorption at these frequencies, as well as the potential for extremely high data rates that comes with it.
Scientists at the National University of Singapore (NUS) have created a microporous covalent organic framework with dense donor–acceptor lattices and engineered linkages for the efficient and clean production of hydrogen peroxide (H2O2) through the photosynthesis process with water and air.
Traditional industrial production of H2O2 via the anthraquinone process using hydrogen and oxygen, is highly energy-intensive. This approach employs toxic solvents and expensive noble-metal catalysts, and generates substantial waste from side reactions.
Researchers at the University of Rochester’s Laboratory for Laser Energetics (LLE) have led experiments showcasing an efficient “spark plug” for direct-drive approaches to inertial confinement fusion (ICF). In a pair of studies featured in Nature Physics, the team shares their findings and details the potential for scaling up these methods, aiming for successful fusion in a future facility.
LLE is the largest university-based U.S. Department of Energy program and hosts the OMEGA laser system, which is the largest academic laser in the world but still almost one hundredth the energy of the National Ignition Facility (NIF) at the Lawrence Livermore National Laboratory in California. With OMEGA, Rochester scientists completed several successful attempts to fire 28 kilojoules of laser energy at small capsules filled with deuterium and tritium fuel, causing the capsules to implode and produce a plasma hot enough to initiate fusion reactions between the fuel nuclei. The experiments caused fusion reactions that produced more energy than the amount of energy in the central hot plasma.
The OMEGA experiments use direct laser illumination of the capsule and differ from the indirect drive approach used on the NIF. When using the indirect drive approach, the laser light is converted into X-rays that in turn drive the capsule implosion. The NIF used indirect drive to irradiate a capsule with X-rays using about 2,000 kilojoules of laser energy. This led to a 2022 breakthrough at NIF in achieving fusion ignition —a fusion reaction that creates a net gain of energy from the target.
