In the first and second parts of this series, pv magazine reviewed the productive lifespan of residential solar panels and inverters. Here, we examine home batteries, how well they perform over time, and how long they last.

Residential energy storage has become an increasingly popular feature of home solar. A recent SunPower survey of more than 1,500 households found that about 40% of Americans worry about power outages on a regular basis. Of the survey respondents actively considering solar for their homes, 70% said they planned to include a battery energy storage system.

Besides providing backup power during outages, many batteries are integrated with technology that allows for intelligent scheduling of the import and export of energy. The goal is to maximize the value of the home’s solar system. And, some batteries are optimized to integrate an electric vehicle charger.

Tesla suspends the base Model Y AWD in the United States. This might have to do with the upcoming Cybertruck and 4680-cell shortage at Giga Texas.

Tesla has built new in-car software specifically for Hertz’s growing fleet of Tesla vehicles for rent around the world.

Back in 2021, Hertz announced an important effort to electrify its fleet of rental cars, led by a massive purchase of 100,000 Tesla Model 3 vehicles. More recently, the company added Model Y vehicles to the order.

The rental company’s Tesla fleet has been growing over the last few years, and it reported that Tesla vehicles are increasing Hertz’s customer satisfaction.

A study showing how electrons flow around sharp bends, such as those found in integrated circuits, has the potential to improve how these circuits, commonly used in electronic and optoelectronic devices, are designed.

It has been known theoretically for about 80 years that when electrons travel around bends, they tend to heat up because their flow lines get squished locally. Until now, however, no one had measured the heat, for which imaging the flow lines is first needed.

The research team, led by Nathaniel M. Gabor at the University of California, Riverside, imaged streamlines of electric current by designing an “electrofoil,” a new type of device that allows for the contortion, compression, and expansion of streamlines of electric currents in the same way airplane wings contort, compress, and expand the flow of air.

The research involved shooting laser beams thinner than the width of human hair on minerals found in an Australian diamond mine.

A collaboration between researchers in the UK, China, and Australia has found the elusive ingredient needed to turn diamonds pink in color, a press release said. This crucial information could help in finding more deposits of the rare precious stone.

It is widely known that the formation of diamonds happens deep inside the Earth. Diamond deposits and mines, however, occur at much shallower depths. This is made possible by the rapid transportation of these carbon structures by deep Earth volcanoes that bring them closer to the surface.

It’s not rocket science, but instead “carbon-neutral” jet-fuel science.

It’s simply a method for pulling carbon pollution and water from the air and using the sun’s energy to turn these into fuel for an airplane.

Japanese researchers hope that a made-in-Japan AI chatbot could help to accelerate science.

Best known for automobiles and consumer electronics, Japan has fallen behind on recent technology trends like artificial intelligence. Its scientists believe that as the country’s population shrinks, Japan will have a strong incentive to make great leaps in AI and robotics to maintain productivity.

Although ChatGPT is being used by Japanese municipalities to carry out governmental work, Japanese scientists say that the country needs to come up with its own version of ChatGPT.

Elon Musk’s hard-edged electric reinterpretation of the pickup truck excites his fans, puzzles auto experts and frustrates environmentalists.

Singapore’s first electric cargo vessel is due to start sea trials and launch in the fourth quarter, according to Yinson Green Technologies, part of a consortium chosen by the city-state to help electrify marine craft.

The Hydromover, developed by the Goal Zero consortium, is near completion, YGT Chief Executive Officer Eirik Barclay said in an interview in Kuala Lumpur this week. YGT will also be introducing an electric vessel for transferring crew — developed with Norwegian startup Lift Ocean AS — by the end of the year, Barclay said. That craft is called the Hydroglyder.

“We want to be part of all associated services with clean electric vessels, starting with Singapore,” Barclay said. YGT is a subsidiary of Malaysia-listed Yinson Holdings Bhd. Yinson shares have risen about 3% this year.
