German energy firm RWE is to invest in a pilot project centered around the deployment of floating solar technology in the North Sea, as part of a wider collaboration focused on the development of “floating solar parks.”

Set to be installed in waters off Ostend, Belgium, the pilot, called Merganser, will have a capacity of 0.5 megawatt peak, or MWp. In a statement earlier this week, RWE said Merganser would be Dutch-Norwegian firm SolarDuck’s first offshore pilot.

RWE said Merganser would provide both itself and SolarDuck with “important first-hand experience in one of the most challenging offshore environments in the world.”

Silicon is one of the most abundant elements on Earth, and in its pure form the material has become the foundation of much of modern technology, from solar cells to computer chips. But silicon’s properties as a semiconductor are far from ideal.

For one thing, although silicon lets electrons whizz through its structure easily, it is much less accommodating to “holes”—electrons’ positively charged counterparts—and harnessing both is important for some kinds of chips. What’s more, silicon is not very good at conducting heat, which is why overheating issues and expensive cooling systems are common in computers.

Now, a team of researchers at MIT, the University of Houston, and other institutions has carried out experiments showing that a material known as cubic boron arsenide overcomes both of these limitations. It provides high mobility to both electrons and holes, and has excellent thermal conductivity. It is, the researchers say, the best semiconductor material ever found, and maybe the best possible one.

Carbon labelling gives consumers a weapon to fight climate change at the cash register.

What’s Involved with Carbon Labelling

Today, nutritional and content labelling can be found on packaged foods. The Government recently announced plans to enhance those labels. Why, because of concerns that Canadians need to learn more about what they eat so that they can make healthier choices.

Scientists studying the aging process in the eye have made an important discovery around the role of a so-called “youth” protein, and shown how it promotes a cellular recycling process that maintains our vision. Experiments on mice missing this protein led to fast-tracked degeneration in the retina, indicating that the protein plays an important protective role against age-related vision loss.

Led by scientists at the US National Eye Institute, the study centers on a protein called pigment epithelium-derived factor (PEDF). This protein plays an important mediatory role in a natural recycling process in the eye. It is produced by a layer of support cells, called the retinal pigment epithelium (RPE), which sits beneath the retina’s light-sensing photoreceptor cells and helps recycle and replenish them as their outer edges wear out. This ability declines as we grow older and in people with age-related macular degeneration (AMD), leading to vision loss.

“People have called PEDF the ‘youth’ protein, because it is abundant in young retinas, but it declines during aging,” said Patricia Becerra, senior author of the study. “This study showed for the first time that just removing PEDF leads to a host of gene changes that mimic aging in the retina.”

EPFL researchers have shown that people’s perception of office temperature can vary considerably. Personalized climate control could therefore help enhance workers’ comfort—and save energy at the same time.

Global warming means that heatwaves are becoming ever-more frequent. At the same time, we’re in a global race against the clock to reduce buildings’ energy use and carbon footprint by 2050. This has shone the spotlight on the importance of making the thermal comfort of buildings a strategic and economic priority. And this is the focus of research conducted by Dolaana Khovalyg, a tenure track assistant professor at EPFL’s School of Architecture, Civil and Environmental Engineering (ENAC) and head of the Laboratory of Integrated Comfort Engineering (ICE), which is linked to the Smart Living Lab in Fribourg.

In her latest study, published as a brief, cutting-edge report in the journal Obesity, she highlights the benefits of providing personalized thermal conditioning and heating for each office desk, rather than maintaining a standard temperature throughout an open space. Khovalyg and her team came to this conclusion after the human thermo-physiological data they collected showed that individuals display very different levels of thermal comfort under normal office conditions.

GM unveiled Monday evening the Chevrolet Blazer EV, an all-electric SUV with up to 320 miles of range and a starting price of $48,000 that CEO and Chairman Mary Barra hopes will supercharge her bid to surpass Tesla in U.S. EV sales by 2025.

The Chevrolet Blazer EV, which will go on sale in 2023 as a 2024 model year, isn’t the only impending GM electric vehicle. A slew of Cadillac and Chevy EVs are also making their way to market. But the Blazer, at its more affordable price point and in the lucrative SUV segment, could kick-start GM’s sales goals.

Internally, the confidence is high. Blazer is going be a massive statement and illustrate how GM can hit big volume segments, according to Scott Bell, Global VP of Chevrolet.
