Physicists Caught Sound Moving at Two Different Speeds in 3D Quantum Gas

Posted by in categories: energy, quantum physics

After previously studying the phenomena of two sound waves in quantum liquids, scientists have now observed sound moving at two different speeds in a quantum gas.

If you were somehow immersed in the three-dimensional gas used for this study, you would hear every sound twice: each individual sound carried by two different sound waves moving at two different speeds.

This is an important development in the field of superfluidity – fluids with no viscosity that can flow without any loss of energy.

Scientists Use Multivalent Cation Additives to Rid Rechargeable Batteries of a Common Pitfall

Scientists are ever-seeking to develop safer, higher-capacity, and faster-charging rechargeable batteries to meet our energy needs sustainably. Metal anodes show the highest promise to achieve that goal. Yet the use of alkali metals poses several problems.

In a rechargeable battery, ions pass from the cathode to the anode when charging, and in the opposite direction when generating power. Repeated deposition and dissolution of metal deforms the structures of lithium and sodium. Additionally, fluctuations in diffusion and electric fields in the electrolytes close to the electrode surface leads to the formation of needle-like microstructures called dendrites. The dendrites are weakly bonded and peel away from the electrodes, resulting in short circuiting and decreases in cycle capacity.

The mobility rEVolution: Microgrid for EV charging, hydrogen fueling, backup power

Posted by in categories: economics, energy, sustainability, transportation

Kaizen Clean Energy (KCE) and ZincFive have come together to develop an integrated distributed energy solution for EV charging, hydrogen fueling and backup power. The new solution is said to provide the lowest delivered cost for hydrogen fueling, as well as up to 2,300 kg/day of hydrogen production, which is equivalent to 38 MWh of usable energy, in a 40-foot, movable containerized solution. It can be islanded or grid-connected, with no risk of battery thermal runaway and a small volume of hydrogen stored on site. The system integrates KCE’s hydrogen generator, ZincFive’s immediate power nickel-zinc batteries, and fuel cells from Power Cell to offer customers modular, scalable economic fueling as a service. Robert Meaney, co-founder of KCE, told pv magazine that the energy input comes from methanol. He said the system is essentially the clean version of a diesel generator. It uses the ZincFive battery for immediate demand response as the methanol-to-hydrogen system ramps up to full production over the first 15 minutes. After entering full production mode, the batteries shut off and the reformer takes over the full power demand. The system is charger agnostic and can support multiple DC fast chargers at once. KCE has started accepting pre-orders and plans to deploy a 20-foot, 150 kW solution with pilot customers in the fourth quarter of 2022.

Lightyear has launched the final design of its long-range, production-ready solar car. The model, which has been renamed “Lightyear 0,” has a Worldwide Harmonized Light Vehicle Test Procedure (WLTP) range of 625 kilometers and consumption of 10.5 kWh per 100 kilometers. However, the Dutch startup claims that a theoretical range of 695 kilometers could be achieved, with a battery pack capacity of 60 kWh. “The optimized solar roof and holistic design mean that the car can drive for weeks, even months, without charging,” the company said. Lightyear is already readying its second solar electric car, which will be available by late 2024 or early 2025.

Renowned carver adopts solar power as clean-energy alternative to diesel on not-so-sunny Haida Gwaii

Posted by in categories: energy, sustainability, transportation

Over the years, Masset, B.C., master carver Jaalen Edenshaw has advocated for clean energy use on the archipelago, a region that is disconnected from B.C. Hydro’s main electricity grid and mainly reliant on diesel.

Since last October, the Haida carver has been teaming up with brother Gwaai to carve a totem pole in honour of Kaay’ahl Laanas hereditary chief Watson Price (Gaahlaay) at a workshop in Masset powered by 18 solar panels that can generate as much as 40 kWh of electricity a day — enough to fully charge a small electric car.

Edenshaw, a member of the Ts’aahl Eagle Clan, is renowned for his traditional creations, including masks, canoes, and 13-metre high red cedar totem poles that are on display in galleries around the world.

Ironic! Norway is Building a Massive Wind Farm to Boost Oil Production

Posted by in category: energy

In a huge twist of irony, Norway is building the world’s largest wind farm — to power offshore oil and gas fields.

If you’re raising your eyebrows at this point, we are too.

The project called Hywind Tampen is set to be constructed and operated by Norwegian energy giant Equinor, who also happens to be drilling for oil and gas in the area.

New electrocatalyst offers hope for less expensive hydrogen fuel

Posted by in categories: chemistry, energy, sustainability

There are a handful of ways to produce hydrogen fuel without emitting carbon into Earth’s atmosphere. One involves using electricity to split water into hydrogen and oxygen.

This method, known as electrolysis, requires a catalyst that speeds up that occur within cells.

More often than not, this electrocatalyst is platinum, a metal so rare that it’s typically more expensive than gold, which makes the more costly than traditional sources of renewable energy and fossil fuels.

Tesla Model Y with new 4680 cells shows impressive potential for faster charging

Posted by in categories: energy, sustainability, transportation

Early experiences with the new Tesla Model Y with 4,680 cells and a structural battery pack are showing some impressive potential for faster charging and better energy density.

When Tesla delivered its first made-in-Texas Model Y vehicles, we noted that it was strange that Tesla didn’t reveal any details – like specs and pricing – about the new version of the electric SUV.
