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.

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.

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.

We learned a little more over the next few weeks. The new Texas-built Model Y Standard starts at $59,990, has a range of 279 miles, goes 0–60 mph acceleration in five seconds, and is equipped with a few new features, including a magnetic center console armrest and a parcel shelf. But we are more interested in the impact of the new battery cell and structural battery pack.

Why the Public Perception of Tesla is TOTALLY wrong:

Shared by Michael Michalchik.

Almost everything commonly told about Tesla is wrong! He didn’t invent AC, he didn’t battle Edison over AC vs. DC, he didn’t even have a rivalry with Edison, he didn’t want to give everyone free electricity and he wasn’t a Physics genius! Referencing primary sources I can show you why we have such a perverted view of Tesla’s real accomplishments and life.

According the company, this innovative system enables the detection of live objects behind walls at a distance of more than 50 meters.

Camero-Tech, a member of the SK Group and an Israeli developer, producer, and marketer of pulse-based UWB micro-power radar ‘Through Wall Imaging’ systems, announced the launching of its groundbreaking XaverTM LR40 (XLR40) system, which detects live objects behind walls at distances of over 50 meters.

Italian company Energy Dome has announced the successful launch of its first CO2 Battery facility in Sardinia, Italy. The milestone marks the final de-risking of the CO2 Battery technology as Energy Dome enters the commercial scaling phase, becoming the first commercial long-duration energy storage technology on the market offering a reliable alternative to fossil fuels for dispatchable baseload power globally.

The Energy Dome CO2 battery uses carbon dioxide to store renewable energy, such as solar and wind energy, over a long period and release it quickly. Energy Dome says the technology can be quickly deployed anywhere in the world at less than half the cost of similar-sized lithium battery storage facilities.

Energy Dome began its operations in February 2020 and has progressed from a concept to full testing at a multi-megawatt scale in just over two years. This successful launch is also in part due to the unique nature of Energy Dome’s process, which integrates known components in a novel industrial process based on a thermodynamic transformation of CO2.

Devices made of readily available oxide and carbon-based materials can produce clean hydrogen from water over weeks — according to new research (Nature Materials, “Long-term solar water and CO 2 splitting with photoelectrochemical BiOI–BiVO 4 tandems”).

The findings, co-led by Dr Virgil Andrei, a Research Fellow at St John’s College, University of Cambridge, with academics at Imperial College London, could help overcome one of the key issues in solar fuel production, where current earth-abundant light-absorbing materials are limited through either their performance or stability.
