Researchers develop high-performance stretchable solar cells

Posted by in categories: chemistry, engineering, solar power, sustainability, wearables

With the market for wearable electric devices growing rapidly, stretchable solar cells that can function under strain have received considerable attention as an energy source. To build such solar cells, it is necessary that their photoactive layer, which converts light into electricity, shows high electrical performance while possessing mechanical elasticity. However, satisfying both of these two requirements is challenging, making stretchable solar cells difficult to develop.

A KAIST research team from the Department of Chemical and Biomolecular Engineering (CBE) led by Professor Bumjoon Kim announced the development of a new conductive polymer material that achieved both high electrical performance and elasticity while introducing the world’s highest-performing stretchable organic solar cell.

Some of the first Cybertruck owners are already customizing their vehicles with wraps and tints

Posted by in categories: sustainability, transportation

The Cybertruck has only been out for a month, and in limited numbers, but some Tesla owners are already customizing their vehicles.

New Cybertrucks are getting colored wraps, window tints, and protective coverings. Joe Torbati, the owner of OCDetailing in Fremont, California, told Business Insider he’d received dozens of reachouts after posting a series of YouTube videos showing work he’d done for a new owner on their vehicle.

“We’ve probably been getting about 10 Cybertruck-related emails or contacts per day,” Torbati said. “Though, it’s not the traditional reason you would wrap a car, which would be to protect it — the point of this is more for just aesthetics,” he added.

ABJ: Tesla expands to suburb northeast of Austin as footprint grows

Posted by in categories: business, Elon Musk, energy, sustainability, transportation

AUSTIN (Austin Business Journal) — Tesla Inc.’s growing footprint in the Austin area now includes a sizable facility in Hutto. But what it’s for remains unclear.

The Austin Business Journal visited the 36,000-square-foot site at 200 County Road 199 in the fast-growing industrial hub northeast of Austin in late December. The parking lot was full and a nondescript warehouse-style building was bustling with employees in construction vests and helmets, but there were no signs listing any companies and no clear indications of who was occupying it. The only traces it could be Tesla were a handful of the company’s electric vehicle charging stations out front.

But Elon Musk’s EV manufacturing and clean energy company is linked to the site in state filings, and it has been confirmed by Hutto officials. Tesla’s expansion to Hutto underscores the company’s wide-reaching plans for the region — as far south as San Antonio and, now, as far north as Hutto — as it continues buildout of its multibillion-dollar operation in eastern Travis County. The Hutto site is about 30 miles directly north of its gigafactory, which serves as the company’s headquarters, along State Highway 130.

Synthetic biology breakthrough fixes CO2 from the air better than nature

Posted by in categories: bioengineering, biological, chemistry, sustainability

Scientists at the Max Planck Institute have developed a synthetic pathway that can capture CO2 from the air more efficiently than in nature, and shown how to implement it into living bacteria. The technique could help make biofuels and other products in a sustainable way.

Plants are famous for their ability to convert carbon dioxide from the air into chemical energy to fuel their growth. With way too much CO2 in the atmosphere already and more being blasted out every day, it’s no wonder scientists are turning to this natural process to help rein levels back in, while producing fuels and other useful molecules on the side.

In the new study, Max Planck scientists developed a brand new CO2-fixation pathway that works even better than nature’s own tried-and-true method. They call it the THETA cycle, and it uses 17 different biocatalysts to produce a molecule called acetyl-CoA, which is a key building block in a range of biofuels, materials and pharmaceuticals.

Algae as a Surprising Meat Alternative and Source of Environmentally Friendly Protein

Posted by in categories: food, sustainability

With more of us looking for alternatives to eating animals, new research has found a surprising environmentally friendly source of protein – algae.

The University of Exeter study has been published in The Journal of Nutrition and is the first of its kind to demonstrate that the ingestion of two of the most commercially available algal species are rich in protein which supports muscle remodeling in young healthy adults. Their findings suggest that algae may be an interesting and sustainable alternative to animal-derived protein with respect to maintaining and building muscle.

Researcher Ino Van Der Heijden from the University of Exeter said: “Our work has shown algae could become part of a secure and sustainable food future. With more and more people trying to eat less meat because of ethical and environmental reasons, there is growing interest in nonanimal-derived and sustainably produced protein. We believe it’s important and necessary to start looking into these alternatives and we’ve identified algae as a promising novel protein source.”

The Transformative Potential of AGI — and When It Might Arrive

Posted by in categories: robotics/AI, sustainability, transportation

The Chinese automaker sold over 3 million clean energy vehicles, with Tesla reporting just 1.35 million in the first three quarters of the year.

Chinese electric vehicle company Build Your Dreams (BYD) is set to become the largest EV maker in 2023, overtaking Tesla for the second year in a row.

The hacking of the Municipal Water Authority of Aliquippa is prompting new warnings from U.S. security officials at a time when states and the federal government are wrestling with how to harden water utilities against cyberattacks.

The danger, officials say, is hackers gaining control of automated equipment to shut down pumps that supply drinking water or contaminate drinking water by reprogramming automated chemical treatments. Besides Iran, other potentially hostile geopolitical rivals, including China, are viewed by U.S. officials as a threat.
