South Korea fines Tesla $2.2 million for exaggerating driving range of EVs

Posted by in categories: sustainability, transportation

SEOUL (Reuters) — South Korea’s antitrust regulator said it would impose a 2.85 billion won ($2.2 million) fine on Tesla Inc for failing to tell its customers about the shorter driving range of its electric vehicles (EVs) in low temperatures.

The Korea Fair Trade Commission (KFTC) said that Tesla had exaggerated the “driving ranges of its cars on a single charge, their fuel cost-effectiveness compared to gasoline vehicles as well as the performance of its Superchargers” on its official local website since August 2019 until recently.

The driving range of the U.S. EV manufacturer’s cars plunge in cold weather by up to 50.5% versus how they are advertised online, the KFTC said in a statement on Tuesday.

Innovation strengthens electron-triggered light emissions for quantum-based computational and communications systems

Posted by in categories: computing, nanotechnology, quantum physics, solar power, sustainability

The way electrons interact with photons of light is a vital part of many modern technologies, from lasers to solar panels to LEDs. But the interaction is inherently weak because of a major mismatch in scale: the wavelength of visible light is about 1,000 times larger than an electron, so the way the two things affect each other is limited by that disparity.

Now, researchers at The University of Hong Kong (HKU), MIT and other universities say they have come up with an innovative way to make more robust interactions between photons and electrons possible, that produces a hundredfold increase in the emission of light from a phenomenon called Smith-Purcell radiation. The findings have potential ramifications for both and fundamental scientific research, although it will require more years of investigation to put into practice.

The findings are published in Nature by Dr. Yi Yang (Assistant Professor of the Department of Physics at HKU and a former postdoc at MIT), Dr. Charles Roques-carmes (Postdoctoral Associate at MIT) and Professors Marin Soljačić and John Joannopoulos (MIT professors). The research team also included Steven Kooi at MIT’s Institute for Soldier Nanotechnologies, Haoning Tang and Eric Mazur at Harvard University, Justin Beroz at MIT, and Ido Kaminer at Technion-Israel Institute of Technology.

More links aren’t necessarily better for hybrid nanomaterials

Posted by in categories: nanotechnology, solar power, sustainability

Chemists from Rice University and the University of Texas at Austin discovered more isn’t always better when it comes to packing charge-acceptor molecules on the surface of semiconducting nanocrystals.

The combination of organic and inorganic components in hybrid nanomaterials can be tailored to capture, detect, convert or control light in unique ways. Interest in these materials is high, and the pace of scientific publication about them has grown more than tenfold over the past 20 years. For example, they could potentially improve the efficiency of solar power systems by harvesting energy from wavelengths of sunlight—like infrared—that are missed by traditional photovoltaic solar panels.

To create the materials, chemists marry nanocrystals of light-capturing semiconductors with “charge acceptor” molecules that act as , attaching to the semiconductor’s surface and transporting electrons away from the nanocrystals.

Cruz Foam taps DiCaprio and Kutcher in $3.5M greentech seed

Posted by in categories: life extension, sustainability

Year 2022 😗


Plastic foam like Styrofoam is a ubiquitous, harmful and nearly immortal single-use material that is long overdue for a good, green replacement — and Cruz Foam is here to supply it. The startup creates a durable yet backyard-compostable packing foam out of shrimp shells produced (and discarded) by the seafood industry. It recently extended its seed round to accommodate the interests of Leonardo DiCaprio and Ashton Kutcher, and is scaling up to meet the demands of its first major customer, Whirlpool.

I met Cruz Foam co-founder John Felts during the memorable Accelerator at Sea hosted by the Sustainable Ocean Alliance. His pitch made perfect sense: create a biodegradable alternative to expanded polystyrene (EPS) foam using a material provided in abundance by nature.

Pondering a world without humans

Posted by in categories: ethics, information science, sustainability, transhumanism

H umans are at the center of most discussions about both the environment and technology. One goal of sustainability is to ensure that future generations of humans have opportunities to thrive on planet Earth. Debates about the ethics of technology often focus on how to protect human rights and promote human autonomy.

At the same time, some conversations about the environment and technology are now taking humans out of the equation. As Adam Kirsch points out in a new book, “The Revolt Against Humanity: Imagining a Future Without Us,” people in two very different schools of thought are coming to a similar conclusion: that the world might not have people much longer and might be better off as a result.

Kirsch takes readers on a guided tour of the discussions in these two camps. “Antihumanists” are obsessed with our having sown the seeds of our demise and bringing environmental apocalypse upon ourselves — possibly even deserving to go extinct. “Transhumanists” are obsessed with maintaining control and envision a future in which we use technology to become something greater than homo sapiens and even cheat death itself.

We’re about to get our first demonstration of space-based solar power

Posted by in categories: solar power, space, sustainability

A new demo from Caltech will test the viability of unlimited solar power beamed back to Earth from orbit.

A new demo from Caltech is set to launch in January 2023, and it could shake up the way we collect and harvest solar power in the future.

2 adults and 2 children survive after Tesla plunges 250 feet off California cliff: “An absolute miracle”

Posted by in categories: sustainability, transportation

250 feet down a cliff. Notice many of the Musk bashing news outlets are not reporting this. #PleaseShare


Montara, Calif. — A 4-year-old girl, a 9-year-old boy and two adults survived Monday after their car plunged off a Northern California cliff along the Pacific Coast Highway near an area known as Devil’s Slide that’s known for fatal wrecks, officials said.

The Tesla sedan plummeted more than 250 feet from the highway and crashed into a rocky outcropping. It appears to have flipped a few times before landing on its wheels, wedged against the cliff just feet from the surf, according to Brian Pottenger, a battalion chief for Coastside Fire Protection District/Cal Fire.

These robots inspect and repair wind turbines, so humans don’t have to

Posted by in categories: robotics/AI, sustainability

Aerones’ robot decreases downtime by almost ten times and increases annual production by 12 percent.

Although wind turbine towers create clean electricity, they frequently leak oil, damaging the blades, increasing wind resistance, and even polluting the ground below.
