In Seawater, Researchers See an Untapped Bounty of Critical Metals

Researchers and companies are aiming to draw key minerals, including lithium and magnesium, from ocean water, desalination plant residue, and industrial waste brine. They say their processes will use less land and produce less pollution than mining, but major hurdles remain.

Can metals that naturally occur in seawater be mined, and can they be mined sustainably? Continue reading

The Most Important View, If Climate Change Interests You

Tree house lodging is not new, but beyond beauty is impact. In that regard the accommodations with the most important view right now might be here:

The Highest Tree House in the Amazon

In 2023, conservationists and carpenters converged on Peru to build luxury accommodations in the rain-forest canopy.

Every day, empty logging trucks rumble into Puerto Lucerna, a small outpost on Peru’s Las Piedras River, which snakes through the lush Amazon rain forest. There, workers load them up with pyramids of freshly cut logs—cedar, quinilla, and, most important, ironwoods, which are prized for their hardness and rich color. Continue reading

Industry Pivots Via Carbon Sequestration

This gas processing plant at Casalborsetti is the focus of the first phase of an ambitious plan to capture carbon dioxide and bury it under the sea. Maurizio Fiorino for The New York Times

Where to put carbon is a major question of the day. Thanks to writers like Stanley Reed and publications like the New York Times the ideas keep coming:

Plan to Stash Pollution Beneath the Sea Could Save Money and Jobs

The Italian energy giant Eni sees future profits from collecting carbon dioxide and pumping it into natural gas fields that have been exhausted.

Renowned for ancient churches and the tomb of Dante, the 14th-century poet, the city of Ravenna and its environs along Italy’s Adriatic coast are also home to old-line industries like steel and fertilizer. Continue reading

An Oil Company Funding Carbon Capture?

The plant will be powered by geothermal energy. Francesca Jones for The New York Times

David Gelles in the New York Times furthers our understanding of the expanding use of carbon capture, and the motives of the key actors utilizing this technology:

On a windswept Icelandic plateau, an international team of engineers and executives is powering up an innovative machine designed to alter the very composition of Earth’s atmosphere.

“Collector containers” where air is pulled in. Francesca Jones for The New York Times

If all goes as planned, the enormous vacuum will soon be sucking up vast quantities of air, stripping out carbon dioxide and then locking away those greenhouse gases deep underground in ancient stone — greenhouse gases that would otherwise continue heating up the globe.

Just a few years ago, technologies like these, that attempt to re-engineer the natural environment, were on the scientific fringe. They were too expensive, too impractical, too sci-fi. Continue reading

Dutch Water Knowhow Is Respectable

We respect the Dutch for their respect of nature, particularly their respect for the power of water and their longstanding determination to harmonize our life with it. This profile extends our respect:

A Dutch Architect’s Vision of Cities That Float on Water

What if building on the water could be safer and sturdier than building on flood-prone land?

In a corner of the Rijksmuseum hangs a seventeenth-century cityscape by the Dutch Golden Age painter Gerrit Berckheyde, “View of the Golden Bend in the Herengracht,” which depicts the construction of Baroque mansions along one of Amsterdam’s main canals. Handsome double-wide brick buildings line the Herengracht’s banks, their corniced façades reflected on the water’s surface. Interspersed among the new homes are spaces, like gaps in a young child’s smile, where vacant lots have yet to be developed.

For the Dutch architect Koen Olthuis, the painting serves as a reminder that much of his country has been built on top of the water. The Netherlands (whose name means “low countries”) lies in a delta where three major rivers—the Rhine, the Meuse, and the Scheldt—meet the open expanse of the North Sea. More than a quarter of the country sits below sea level. Over hundreds of years, the Dutch have struggled to manage their sodden patchwork of land. Continue reading

Italy has not figured in our climate change solutions coverage, until now. Our thanks to Stephen Wallis and the New York Times for this:

A Growth Spurt in Green Architecture

Buildings made shaggy with vegetation or fragrant with wood are no longer novelties.

In the lineup of climate villains, architecture towers above many. The building and construction industries account for some 37 percent of worldwide carbon dioxide emissions, according to the United Nations Environment Program. Three of the most commonly used building materials — concrete, steel and aluminum — generate nearly a quarter of all carbon output. Continue reading

Embodied Carbon

Thanks to Yale Climate Connections for expanding our vocabulary:

What is ‘embodied carbon’?

It’s a little-known but major factor in the carbon footprint of our buildings.

Buildings can create a lot of global warming carbon pollution, from the electricity for lights and appliances to the oil or gas used to power the furnace.

Celebrating KithenAid’s Build To Last Determination

Sharing this article is not with the intent to promote KitchenAid, per se. But okay if it does. More to appreciate The Atlantic for bringing your attention to a practice that is in short supply. Some companies do not build for obsolescence. Thanks to Anna Kramer for this:

Modern appliances are rarely built to last. They could learn something from the KitchenAid stand mixer.

My KitchenAid stand mixer is older than I am. My dad bought the white-enameled machine 35 years ago, during a brief first marriage. The bits of batter crusted into its cracks could be from the pasta I made yesterday or from the bread he made then. Continue reading

Jaron Lanier On Virtual Reality

Illustration by Jackie Carlise

Jaron Lanier has been our go-to voice of reason at important moments in technology hype. Here is his take on the latest hype:

Where Will Virtual Reality Take Us?

Apple’s Vision Pro headset suggests one possible future—but there are others.

Because we in Silicon Valley are newness junkies, it can feel like an act of sabotage to have memories, but, for better or worse, I have them. It’s been more than forty years since I co-founded the first company to make headsets and software for simulated experiences, and came up with familiar terms like virtual and mixed reality.

Thanks to Bill McKibben, in his newsletter–“A Corrupted COP New revelations show just how bad the oil countries really are“–for more details on this bad news but also for pointing us to better news that has implications for so much of the decarbonization opportunity set:

Battery Prices Are Falling Again as Raw Material Costs Drop

BloombergNEF breaks down the biggest annual drop in its lithium-ion battery price survey since 2018.

As the auto industry grapples with how to make affordable EVs, the task may get easier by one key metric. Battery prices are resuming a long-term trend of decline, following an unprecedented increase last year.

According to BloombergNEF’s annual lithium-ion battery price survey, average pack prices fell to $139 per kilowatt hour this year, a 14% drop from $161/kWh in 2022.1

Understanding Seawalls, Their Promise & Their Limits

Daniel A. Gross does some heavy lifting on behalf of all of us, especially those in coastal areas. This technology is foreign to most of us, except the Dutch. We can hope all we want, but now might be a good time to start thinking more seriously about whether this technology is fit for the task:

Can Seawalls Save Us?

Huge coastal barriers could protect the world’s cities. But they’ll have unexpected costs.

Pacifica, California, just south of San Francisco, is the kind of beachfront community that longtime residents compare to Heaven. One of its streets is called Paradise Drive; local fishermen brag that Pacifica Pier is among the state’s best places to catch salmon, striped bass, and crab. Every few years, a superbloom blankets the coast with golden wildflowers. When the sun cuts through the region’s famous fog, the sky sometimes glows, as in a Turner painting.

Some of Pacifica’s most dramatic views could be found on Esplanade Drive, where mid-century developers built bungalows on top of a cliff. For almost fifty years, residents gazed out from their back yards to see whales splashing in the Pacific. Then, in 1998, a group of homeowners gathered to say goodbye. “I cannot express how spectacular it has been living here,” one of them, Joe Parker, said at the time. “I’ve seen dolphins out there. I recognize all the seabirds.” Beverly Axelrod, who had spent fourteen years on Esplanade Drive, recalled how her ocean view had “healed everything.” Continue reading

What’s New With Wind Propelled Ships

Thank you as always, Cara Buckley. The topic today is wind power, again, this time more on its use propelling ships:

More ships are running on wind power, as the global industry tries to fight climate change. One concept has backing from Abba, the Swedish pop stars.

One ship was pulled across the sea with the help of an enormous sail that looked as if it belonged to a kite-surfing giant. Another navigated the oceans between China and Brazil this summer with steel and composite-glass sails as high as three telephone poles. Continue reading

The Cutting Edge Of Wind Turbine Technology

Bats need protection; these clever engineers and scientists will surely figure out how to, considering what they have already accomplished:

Spinning Wind Turbines Kill Nearly a Million Bats a Year. Researchers Aim to Find Out Why

Land-based wind turbines kill as many as 880,000 bats a year, wiping out so many threatened bats that at least one species could soon become endangered without preventative action, according to a recent study.

Bat conservation experts and scientists say they currently do not know how to stop turbine collisions. Continue reading

Dear AI Overlords, Reviewed

Virginia Heffernan has appeared in our pages only once before, also reviewing a book. She is one of the great writers in the English language, but often on topics not connected to our themes here. While we mostly are interested in topics related to the natural world, and we know that this topic is a whole other realm, we can guess that AI’s impact on the natural world is part of what the title of this issue of Wired will mean to us pretty soon:

What If the Robots Were Very Nice While They Took Over the World?

First it was chess and Go. Now AI can beat us at Diplomacy, the most human of board games. The way it wins offers hope that maybe AI will be a delight.

THE MORRISSEY HAD the right melodrama in his limbs, and his voice was strong and pained. I was at Gramercy Theatre in Manhattan to see a Smiths tribute band. I tried to get Morrissey’s acid yodel in my throat, to sing along. I am human and I need to be loved / just like everybody else does. But it didn’t feel right to copy a copy. Continue reading

CRISPR Silk

This will be the fifth time for CRISPR in our pages. We suspend judgement each time we link to explanations of the technology, or new applications:

Silkworms genetically engineered to produce pure spider silk

Spider silk has been seen as a greener alternative to artificial fibres like nylon and Kevlar, but spiders are notoriously hard to farm. Now researchers have used CRISPR to genetically engineer silkworms that produce pure spider silk

Silkworms have been genetically engineered with CRISPR to produce pure spider silk for the first time. The worms could offer a scalable way to create things like surgical thread or bulletproof vests from spider silk, which is prized for its strength, flexibility and lightness. Continue reading

Species-Specific Safe Spaces

We have pointed to stories about activism and entrepreneurship in the interest of protecting animal habitat plenty of times, but not so much on the science of the field work. As part of its Climate Desk collaboration Mother Jones shares this article originally published by Undark, written by Marta Zaraska, that addresses some of the science of species-specific safe spaces:

Inside Scientists’ Race to Create Safe Refuges for Animals

Climate crisis is destroying habitats. Can technology help create new ones?

In 2016, Ox Lennon was trying to peek in the crevices inside a pile of rocks. They considered everything from injecting builders’ foam into the tiny spaces to create a mold to dumping a heap of stones into a CT scanner. Still, they couldn’t get the data they were after: how to stack rocks so that a mouse wouldn’t squeeze through, but a small lizard could hide safely inside. Continue reading

Carbon Capture, Scaled To Texas

Carbon capture technology has its skeptics, but it has steadily improved and is closer to proof of concept. Next step, scaling to Texas:

The world’s biggest carbon capture facility is being built in Texas. Will it work?

The plant will inject 500,000 tons of carbon dioxide into the ground each year – but is it just greenwashing from big oil?

Rising out of the arid scrubland of western Texas is the world’s largest project yet to remove excess carbon dioxide (CO2) from the atmosphere, a quest that has been lauded as essential to help avert climate catastrophe. The project has now been awarded funding from the Biden administration, even as critics attack it as a fossil fuel industry-backed distraction. Continue reading

The Coming Wave, Reviewed

The primary author of this book is one of the pioneers of AI, so what he has to say about it as a dilemma is relevant. From a recent conversation he had with Sam Harris my takeaway was that while I do not have much agency in the dilemma, it is better for me to understand it than ignore it. Containment is not, apparently, an option. So what can I do? In this book review, a quicker version of the same message, and the only option may be to ponder it:

The Coming Wave by Mustafa Suleyman review – a tech tsunami

The co-founder of DeepMind issues a terrifying warning about AI and synthetic biology – but how seriously should we take it?

On 22 February 1946, George Kennan, an American diplomat stationed in Moscow, dictated a 5,000-word cable to Washington. In this famous telegram, Kennan warned that the Soviet Union’s commitment to communism meant that it was inherently expansionist, and urged the US government to resist any attempts by the Soviets to increase their influence. This strategy quickly became known as “containment” – and defined American foreign policy for the next 40 years. Continue reading

Heat Pumps Questioned

The technology of heat pumps was made understandable in an earlier article. While remarkable, questions have arisen. Read the following in full at The Economist to hear about it in more detail:

Heat pumps show how hard decarbonisation will be

The row over them portends more backlashes against greenery

They hang from the walls of utility rooms, nestle inside kitchen cupboards and hunker down in cellars. Continue reading

Driverless Taxi, Anyone?

Apparently there is a market for this service in San Francisco, according to Jeremy Hsu at New Scientist, in spite of the objections:

California approves driverless taxi expansion in San Francisco

Waymo and Cruise can now charge for ride-hailing services throughout San Francisco despite objections that driverless cars interfere with traffic and first responders

Driverless cars have the green light to operate as paid ride-hailing services in San Francisco after the companies Waymo and Cruise won approval from California state regulators. Continue reading
