Wind turbines are a feat of engineering. The massive structures are visually impressive and generate vast amounts of clean energy via a natural and pollution-free source.
Because of that, you’d think they take a long time to install — especially when placed far out at sea.
However, at an offshore wind farm in Zhangpu, China, the state-owned China Three Gorges power company managed to get one up and running in just over a day, Electrek reports.
Researchers at MIT have created a device that may soon be able to turn seawater into drinking water for entire households using nothing but solar energy.
And, to top it off, the water produced by this device could eventually cost less than US tap water, according to a paper published last week in the peer-reviewed journal Joule.
Yang Zhong, a graduate student at MIT and an author of the September 27 paper, said this desalination device is more efficient, longer-lasting, and cheaper than previous desalination devices.
Lightweight materials with super strength and toughness are highly sought after. Spider silk, a sustainable material, meets these requirements but faces challenges in commercialization due to scientific understanding of its spinning mechanism, technical complexities in the process, and engineering hurdles in low-cost mass production. Here, drawing inspiration from nylon and Kevlar, we propose a theory on the nature of toughness and strength, unveiling the basic structure of silk fibers. Using these theories, we successfully produce the first “localized” full-length spider silk fiber via transgenic silkworms, showcasing high tensile strength (1,299 MPa) and exceptional toughness (319 MJ/m3). This breakthrough overcomes scientific, technical, and engineering obstacles, paving the way for spider silk’s commercialization as a sustainable substitute for synthetic fibers. Moreover, our theories provide essential guidance for developing super materials.
Developing sustainable materials with high strength and ultra-toughness is vital for ecological civilization. Using transgenic silkworms, we have successfully produced the first full-length spider silk, overcoming the scientific challenge of understanding the essence of toughness and strength. The resulting bionic spider silk exhibits high strength (1,299 MPa) and ultra-toughness (319 MJ/m3), offering a potentially sustainable substitute for synthetic commercial fibers. This breakthrough provides valuable insights for the development of super materials, including those for a space elevator, driving the advancement of civilization.
Tesla is planning to build something called “Giga Water Loop” just outside of Gigafactory Texas in Austin.
But we are not sure what it is.
Gigafatory Texas is arguably Tesla’s most ambitious manufacturing project to date, and that’s saying a lot because the company has many ambitious manufacturing projects.
Norwegian maritime solutions company, Ulstein, has unveiled a new vessel concept that holds the potential to deliver zero-emission cruises and other ocean industry applications, the company said in a press release.
For over a century, Ulstein has been involved in designing and building ships and delivering sustainable maritime solutions. The maritime industry is staring at a major overhaul in its bid to electrify transport over the waters, and Ulstein may just have the solution, a molten salt reactor (MSR) that can deliver this vision.
Mitch Lee can tick off the many environmental advantages of electric boats versus ICE counterparts that rule the waves: No exhaust fumes and pollution. No oil slicks trailing in the wake. No guzzling of pricey marine fuel at 2 kilometers-per-liter or less.
But with all respect to the Sierra Club, Arc Boats isn’t in business to save the planet.
“The climate benefits are certainly there. But our goal is to deliver better boats, period,” says Lee, the CEO and former Boeing engineer whose cofounder and CTO, Ryan Cook, is the former lead engineer of Space X.
And its CTO from Space X.
Austrian startup CycloTech has unveiled CruiseUp, an innovative air vehicle that showcases the benefits of CycloRotor technology and its 360-degree thrust vectoring capabilities, all within a compact, passenger-oriented design.
Drawing on 15 years of technology development, extensive wind tunnel testing, and experience from over 500 flights of its technology demonstrator, the CruiseUp concept is designed to meet the individual air mobility needs expected to emerge in the coming decade. The vehicle promises to unlock new possibilities for everyday activities, enabling comfortable, simple, and safe transportation while also promoting sustainability by replacing pollution-intensive ground-based transportation.
CruiseUp uses CycloRotors as its electric propulsion system. This system is unique because it encapsulates the moving parts, providing an extra layer of safety for both the environment and the two passengers.
Picture a smartphone clad in a casing that’s not just for protection but also doubles as a reservoir of electricity, or an electric car where the doors and floorboard store energy to propel it forward. Such technologies may one day be a reality, thanks to recent work by engineers at the University of California San Diego.
The researchers have developed what’s called a structural supercapacitor—a device that provides both structural support and energy storage capabilities. Such a device could add more power to electronic gadgets and vehicles without adding extra weight, allowing them to last longer on a single charge.
While the concept of structural supercapacitors is not entirely new, it has been a longstanding challenge to create a single device that excels at both bearing mechanical loads and storing electrical energy efficiently. Traditional supercapacitors are great at energy storage but lack the mechanical strength to serve as structural components. On the flip side, structural materials can provide support but fall short when it comes to energy storage.
Tesla is stacking a massive supply of Cybertruck castings at Gigafactory Texas, hinting the production is near, which means deliveries aren’t far behind either.
Tesla Cybertruck production has been nearing for months as the company has shown early-stage validation, public road testing, crash assessments, and some of the best-built Cybertruck units, all within the past few months.
Production is obviously getting close, especially when we base this thought on the fact that public-road testing of RC-labeled, or release candidate, Cybertrucks have been spotted throughout the country over the past month and a half.
We often wonder where we might find a truly sustainable and abundant source of energy, and the answer might turn out to be in the emptiness all around us.
