Having refined its charging algorithms, Polar Night Energy is now ready to scale up the storage tech in Pornainen.

Once completed, the new battery will be integrated with the network of Loviisan Lämpö, the Finnish heating company that supplies district heating in the area.

“Loviisan Lämpö is moving towards more environmentally friendly energy production. With the Sand Battery, we can significantly reduce energy produced by combustion and completely eliminate the use of oil,” says CEO Mikko Paajanen.

The benefits of fleet electrification are well-known, but the question of feasibility is still very real in the minds of many heavy fleet managers. To help fleets understand how electric trucks can fit into their operations, Mack Trucks is offering a mobile off-grid charging system.

Mack made the announcement earlier this week at the American Trucking Associations Technology and Maintenance Council Annual Meeting, where they showed off renderings of a Mack MD Electric carrying a “renewable propane” powered generator and 120 kW charger. While somewhat clunky as a concept, it should do a reasonable enough job of pretending to be permanent infrastructure to give a fleet manager a sense of whether or not an electric solution will work for them.

“This system will allow the customer or dealer to charge trucks – whether it’s a demo unit or a multi-unit ride-and-drive event at the dealer – without having charging infrastructure readily available at their site,” says Ryan Saba, energy solutions manager for Mack Trucks. “Mack hopes that this option will help customers more easily experience the benefits of e-mobility and a more sustainable transportation option.”

“But in the process, we also made a major finding: that hydrovoltaic devices can operate over a wide range of salinities, contradicting prior understanding that highly purified water was required for best performance.”

The process can generate power around the clock since evaporation occurs at various temperatures and even at night. The process also occurs across humidities, making it suitable for use across the planet, irrespective of location.

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 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) is constructed by a series of corner-sharing triangles. When each corner is occupied with 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 ‘’ 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 for more than eight billion years. This suggested that some 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.
