ENERGY: Does Life Blush?

Posted on February 20, 2024 by Building The World

Does life blush? Pink may be the color of nascent energy.

Stanley Miller, in 1951, came to the University of Chicago to study with nuclear physicist Edward Teller who had worked on the Manhattan Project, and later established Lawrence Livermore National Laboratory (where recent success in fusion energy was achieved). While Teller’s student, Miller attended a lecture by Harold Urey, Nobel Laureate in Chemistry, on the Oparin-Haldane hypothesis, on the possible origin of organic life from inorganic compounds. After the lecture, Miller approached Urey with an idea for an experiment to test the hypothesis. Urey was skeptical – no one had ever proven the mystery of how life began – but intrigued. The professor granted Miller one year of funding.

Using water (H2O), methane (CH4), ammonia (NH2), and hydrogen (H2) in a mixture – and stimulating them with an electric arc that acted like lightning to produce fast intense heat and then applying a condenser to cool – Miller repeated alternation of heat and cold to see what might happen. The mix of components has the acronym WHAM (water, hydrogen, ammonia, methane).

Soon, water droplets began to form and then a watery solution dripped into what started to look like a tiny pond. Miller left the lab for the night. The next day, he awakened with curiosity and dashed to the lab. The pond was now turning color – a pale pink. Encouraged, he ran to tell Urey. The two watched and waited. In a week, the pink pond turned a reddish brownish black. What was happening?

Miller identified five amino acids that had formed: aspartic acid, glycine, a-aminobutyric acid and two forms of analine (Australian Earth Science Foundation, 2024). This was significant because previous to that moment, all of science avowed that amino acids, molecules of life, could only be built inside living bodies. That belief was traditionally expressed in the phrase “Omne vivum ex vivo“ (All life comes from living things). But now living energy had appeared from inorganic compounds in Miller’s lab. “Primordial soup” – the parlance given to Oparin/Haldane’s hypothesis and picked up by Miller/Urey – was now served. And it was pink.

Professor Harold Urey urged Miler to publish the findings but refused to put his name on the paper for two reasons. First, the idea and experiment was totally Miller’s and the professor was just the verifier. And, Urey worried – with reason – that the journal editors would give him all the credit because of his Nobel status. As predicted, the journal turned down the paper. But Urey wrote them a very clear note about Miller, attached his name as verifier, and they immediately published the findings. Eventually, the experiment became known as Miller-Urey. Harold Urey is also known from discovering deuterium, an isotope of hydrogen, and the process of enriching uranium. Later in life, Urey became interested in space, participating in examination of lunar rocks brought back by Apollo NASA astronauts. A crater on the moon is now named Urey Crater.

Miller-Urey’s demonstration that organic life can spring from inorganic, under certain conditions, recently made news when scientists noted that Last Chance Lake – a shallow body of water in British Columbia – has the highest concentration of phosphate ever found in any natural pond or body of water on Earth. Why is this interesting? Phosphate contains phosphorus, a life-related molecule found in DNA, RNA, and, well, life. Last Chance Lake also has dolomite that triggers reactions among calcium, magnesium, and carbonate. In the geology of the volcanic soil around the lake, phosphate may have been part of how life originated. In geological circles, it’s called a “soda lake;” some say it is just the kind that Darwin envisioned when he wrote to his colleague in February 1871 about a hypothetical “warm little pond.” But as Miller-Urey proved, it is the stimulus and alternation of heat energy that sparked those components to organic life in that pond and in the lab.

Alternation of intense heat energy proved to be the spark of organic life, in the Miller-Urey experiment. Image: “Animated lightning” by Kunal Sen and TIsha Pillai, Wikimedia Foundation, 2021. Creative Commons 4.0. Included with appreciation.

Tesla also placed importance on alternating current. But the idea is not new. Tantra, a philosophy arising around 500 ce in India, proposed that “Spanda” (from Sankrit Spadi “to move back and forth, to vibrate”) was the original energetic force that gave forth life.

The world’s future depends upon energy in clean, renewable, sustainable forms. Solar, wave and wind (caused by thermal alternation), and advances in fusion energy, may lead the way. Interestingly, plasma fusion energy from hydrogen radiates a series of colors from red to aqua, but when they combine, they often produce pink. (Eurofusion 2024). What is it about pink?

TRANSPORT: Super Bowl Sustainability

Posted on February 10, 2024February 11, 2024 by Building The World

“Taylor Swift at 2023 MTV Video Music Awards,” image by iHeartRadioCa. Creative Commons 3.0. Included with appreciation.

Taylor Swift hopes to attend the Super Bowl in Las Vegas but must take a private jet from Japan where she is on tour. Her fans, “Swifties,” quip that the superstar’s flight finally forced a certain news network to actually mention the words: “climate change.” Swift’s previous attendance at the AFC championship game in January resulted in three tons of carbon emissions – and that flight was just from New Jersey to Maryland. Flying over 5,000 miles will require a lot more jet fuel, and result in even more emissions. Joining her plane circling Las Vegas will be an estimated 1000 private jets. Swift is flying to see her boyfriend Travis Kelce of the Kansas City Chiefs play versus the San Francisco 49ers in the football contest.

“Cole Hollcomb and Travis Kelce football in action” All-Pro Reels 2021. https://www.flickr.com/photos/joeglo/51616124289/

Sports fans with private planes are not the only winged emitters. World Economic Forum attendees jetted into Davos, Switzerland in over 1,000 private jets. That’s the same emissions that would be generated by 350,000 cars driving for seven days. Worldwide, in 2022, private jets emitted carbon dioxide totaling 573,000 metric tons.

Commercial aircraft emit carbon dioxide reaching levels of 1 billion tons every year. That is more that the entire country of Germany. If aviation were a country, it would come just after China, USA, India, Russia, and Japan in emissions levels.

Is there a solution? How about flying on leftover sugar, fat, and corn waste? Sustainable Aviation Fuel (SAF) made from biofuels produced from renewable crops or collected waste offers advantages. SAF produces 85% less emissions over its lifecycle. And, importantly, SAF can use the same delivery infrastructure and personnel systems as traditional kerosene-based jet fuel. In 2021, United Airlines flew from Chicago to Washington, DC, using 100% SAF in one of its jet engines. In 2023, Emirates claimed the honor of being the first aircraft to fly an Airbus A380 using 100% SAFs in one of the plane’s engines. Virgin Atlantic’s Boeing 787 flew from London to New York. Gulfstream led private aviation in a flight from Savannah, George to Farnborough Airport in England using 100% SAF.

ENERGY: (Re)Vision for Coal

Posted on December 19, 2023 by Building The World

**Coal-fired power plants, repurposed, may offer great innovation opportunities.** Image: “Coal burning” by Diddi4, 2017. Creative Commons CC0. Included with appreciation.

Many are terming COP28 as the “beginning of the end.” While the desired wording of “phasing out” degraded into “transitioning,” still it was the first time directly naming and targeting “fossil fuels in energy systems.”

Of the three primary fossil fuels (coal, oil, natural gas), coal is the most polluting. And it is also very expensive to mine: digging enormous holes in the ground, hauling up heavy materials, crushing, washing, transporting coal to plants that themselves are both expensive to run and in need of repair, replacement, or retirement. More than 80% of U.S. coal plants cost more to keep running than to replace with new forms of energy generation. Regulations will accelerate closings: the 2028 laws concerning protecting drinking water from coal ash and other toxins may make compliance prohibitively costly. Duke Energy announced intention to close 11 coal-fired power facilities earlier than expected, at the same time declaring a move to renewable energy investment. Georgia Power stated it would close all of its 14 coal plants (by 2035) while pivoting to solar and wind. Peabody Coal, largest private company in the coal business in the world, recently announced investment in solar and storage. (Marcacci, 2022).

Coal is the most polluting of the fossil fuels. Image: “Close up of smoke from coal stack” by John L. Alexandrowicz, 1975, National Archives and Records Administration, USA. Public Domain Creative Commons CC0. Included with appreciation.

Even if soon becoming obsolete in their original purpose, repurposed coal plants offer a valuable asset: they are already wired to the grid. That’s why repurposing rather than decommissioning coal-fired power plants may be a great opportunity. And, it should be noted that repurposing plants will keep jobs, taxes, and revenues in the community. Here’s two examples of advantageous repurposing of coal-fired power plants.

Brayton Point went from coal to wind. Image: “Aerial view of Brayton Point Power Station,” circa 1990, from Massachusetts Department of Environmental Protection. CC2.0. Included with appreciation.

Brayton Point Power Station was once the biggest coal-fired power plant in New England, generating 1600 MW of electrical power for more than half a century. In 2017, the plant closed. One year later, Commercial Development Company, Inc., (CDC) bought what was left and started the process of clean-up, needed demolition, site re-grading, and preparing for a new vision. With 300 acres (121 hectares) on a spacious waterfront with a 34-feet (10 meters) deep water port, the site was advantageous. Brayton Point offered access to the powerful winds of the Atlantic Ocean. When partner Prysmian Group signed on to acquire 47 acres for construction of a subsea cable manufacturing facility, coal-to-wind transition was born with a planned energy capacity of 30GW. Partner Mayflower Wind will also take a role, bringing 1,200 MW to Brayton Point from its wind farms 30 miles (48 kilometers) off island Martha’s Vineyard and 20 miles (32 kilometers) off Nantucket. Brayton Point will serve as a valuable nexus for wind energy because it has legacy grid connections. A National Grid substation will bring power to one million homes. Further benefits are construction jobs (325) and area revenues ($250 million). More opportunities will open for tenants on the newly designed site.

Space Solar Power, wirelessly beamed to Earth, could use retired, repurposed coal-fired power plants as receiving and transmission stations. There are over 8,000 on the planet – offering an instant global distribution network. Caltech demonstrated success in 2023. Image: “Solar Power Satellite Concept” by NASA, 2011. Public domain image included with appreciation.

A powerful possibility is using former coal-fired power plants as land stations to receive and transmit space solar power. In 1971, visionary Peter E. Glaser filed US patent application US00165893A for “Method and apparatus for converting solar radiation to electrical power.” NASA started work on Glaser’s idea, but at the time space technology was not developed sufficiently to realize the potential. In 2023, the dream became vision with demonstrated proof. Caltech’s Space Solar Power Project (SSPP) and its Microwave Array for Power-transfer Low-orbit Experiment (MAPLE) sent a space solar power prototype into orbit, and wirelessly transmitted to a receiver on Earth – March 3, 2023 was the exact moment. The success was designed by a Caltech team led by Bren Professor of Electrical Engineering and Medical Engineering, co-director of SSPP, Ali Hajimiri. It was with the help of Donald Bren, chair of Irvine Company. Bren had read an article in Popular Science as a young person and never forgot the concept. A series of donations launched the Caltech project. Northrop Grumman also donated. It might be noted that when space-based wireless power arrives on earth, the energy source may need receiving stations. Rather than build a whole new network, repurposed coal-fired plants, already connected to the grid, might stand at the ready to realize a new power system. With over 8,000 coal-fired power plants already in place, coal-fired power plants may be the ideal, already-built, global network for reception and distribution of space solar power.

Flying on leftovers, sugar, fat, and corn waste – recipe for Sustainable Aviation Fuel (SAF) – Virgin Atlantic’s Boeing 787 flew from London’s Heathrow to New York’s JFK, joining Emirates and Gulfstream in demonstrating a new “wingprint” for aviation. In some ways, it was just a proof-of-concept: there were no passengers or cargo. But nevertheless, it is a significant milestone for an industry that seeks climate-sensitive solutions to air transport emissions.

1903 to 2023 – just over a century after the Wright Brothers made the first successful flight of a heavier-than-air craft, aviation has begun to transition to sustainable and renewable fuel sources. Recently, Emirates claimed the honor of being the first airline to demonstrate flight of an A380 with 100% SAF. But the aircraft used SAF fuel in only one of the plane’s four engines. Other aviation industry leaders including Airbus, Engine Alliance, Pratt & Whitney, Neste, Virent and others joined the quest. Just days earlier, Gulfstream Aerospace, leader in business and private air travel, completed a transatlantic flight from Savannah, Georgia to Farnborough airport in England. using 100% SAF. Using Pratt & Whitney PW815GA engines, flight fuel was composed of hydroprocessed esters and fatty acids (neat HEFA) biofuel.

What is Sustainable Aviation Fuel (SAF)? It is a fuel produced from non-petroleum based , renewable “feedstocks” that may include food and yard waste from landfills, fats and greases from leftovers in commercial kitchens, and woody biomass. Suppliers include Neste and World Energy. In the United States. the Department of Energy, Department of Transportation, and other agencies signed a Memorandum of Understanding termed the “SAF Grand Challenge” to produce 3 billion gallons (ll billion liters) per year by 2030 and 35 billion gallons (132 billion liters) per year by 2050.

When the International Civil Aviation Organization (ICAO) met, this week, for the Conference on Aviation and Alternative Fuels, Emirates’, Gulfstream’s, and Virgin’s achievements served to accelerate progress towards the goal of making all aircraft capable of flying with 100% SAF by 2030. Presently, commercial airlines can use only 50% SAF while safety tests continue.

Aviation’s new wingprint – dawn of a era. Image: “Flying through the sunrise” by Lenny K. Photography, 2015. Creative Commons 2.0. Included with appreciation.

SAF could reduce air travel’s carbon “wingprint” by 70%. How? SAF does emit the same amount of greenhouse gases when airborne, but it is made from plants like corn that have already absorbed CO2 before they were cut. So in a sense, SAF is considered cleaner. SAF does not come cheap: it costs 6 times more than regular jet fuels like kerosene. Another factor is land use. Growing enough plants for biofuels would use a lot of land: in the UK, it would consume half of available agricultural land. Instead of traditional biomass SAF, environmental advocates advise development of synthetic fuels made by blending green hydrogen with carbon captured energy. Innovators in what is termed “synthetic kerosene” include Shell, KLM, and start-up Twelve Corporation. The global SAF market, including synthetic kerosene, is predicted to grow by 47% from 2023 to 2030.

**If you live within 1/2 mile (0.8 kilometer) of a fossil fuel processing plant, you may be in a circle of danger**. Image above shows air pollution as it circles the globe. “Air Pollution Earth” by NASA, 2001. Public Domain.

Air pollution is a serious problem worldwide. Burning of fossil fuels, excess vehicular traffic, and lack of green spaces to absorb emissions, are causing clogged skies and public health dangers. Case in point, this month: India.

“Taj Mahal” from a photograph circa 1900. Image source: U.S. Library of Congress. Creative Commons Public Domain. Included with appreciation.

Those who visited India’s famed Taj Mahal may not have been able to see the iconic monument this month. Air pollution fogged India’s skies. New Delhi, home to 35 million people, closed schools and warned residents to stay indoors if possible. NASA’s satellite images showed dense smoke over the landscape. But more troubling was the cause: particulate matter toxins and pollutants so tiny they can pass into human (and animal) airways to cause illness and chronic conditions.

Fireworks: Added Danger – add to present air problems the joyous feast of Diwali, occasion for sky-illuminating, but also air-polluting, fireworks and air pollution becomes more serious. After Diwali, transport authorities are considering calling for an alternation of traffic days, allowing certain vehicles on the road every odd/even day. In some global locations, during seasonal festivals, many cities opt for aerial drone displays rather than traditional fireworks.

Regional – as New Delhi experiences air quality issues, Lahore, Pakistan, home to 13 million people, has also recommended schools, shopping malls, and some businesses, close temporarily. The air quality index (AQI) reached a hazardous level. Air pollution is a transboundary problem.

Pollution Effects Worldwide – 1 in 5 deaths worldwide can be traced to illnesses initiated or worsened by air pollution from fossil fuel combustion. Researchers from the University of Birmingham, University of Leicester, University College, London, and Harvard University found that 8 million people died from causes linked to air pollution in 2018; since then, things have gotten worse.

Circle of Danger – the closer you live to a fossil fuel production facility, the more pollutants you may encounter. Toxins entering the air, and your lungs, include benzene, carbon dioxide, ethylbenzene, formaldehyde, methane, toluene, and xylene. The term for some of these substances is Volatile Organic Compound (VOC). In the United States, there are over 1 million active production wells, natural gas compressor stations, and processing plants, with 12 million people living within 1/2 mile (0.8 kilometer) – the circle of danger.

If we need an energy revolution, this could be it.

There are historic precedents. President Franklin Delano Roosevelt pulled American youth out of Depression-era joblessness by creating the Civilian Conservation Corps (CCC). While initially aimed at those suffering poverty. CCC expanded, through the creative leadership of Frank P. Davidson, to include Camp William James in Tunbridge, Vermont, welcoming college recruits.

But the earliest organization of service work might be the Dike Armies of the medieval Netherlands. In 1319, this edict described the corps: “Ende alman sal ten menen werke comen op den dijc, daers hem ie Baeiliu, of die Dijcgrave vermaent” – “Everybody shall come to work at the dike on instruction of the bailiff or dike reeve.” It should be noted that today, with social media like Instagram, X, TikTok, calling up volunteer teams to respond to a climate disaster would have instant effectiveness.

The newly planned American Climate Corps might be the beginning of a new era of job and skills development to respond to climate change. But a broader vision could expand the scope. Climate change will not stop at national borders: San Diego in the USA and Tijuana in Mexico share the same coast and the same need for response to sea level rise. Vermont, site of CCC Camp William James, shared smoke from Canada’s recent wildfires. Look at Earth from space; you see not countries and nations, but land and water. Climate change must be addressed by regional, and global, response. The American Climate Corps could become a regional organization inviting Canada, Mexico, and the USA, together with the original Tribes of the Americas, to share language training, technology development, and regional capability to respond to climate change.

The new CCC can build wind turbines, delivering green electricity. It’s a fast-growing industry with great jobs. Image: “Dual Rotor Wind Turbine” by Deas1. Creative commons. Included with appreciation.

Those trained by the new Climate Corps can serve a dual role of training for climate-ready jobs, and also be ready to respond to climate disasters that affect the region. In the last decade, 85% of natural disasters like drought and fires, storms and floods, were attributed to, and intensified by, global warming. Climate change calls us to work together in ways that can strengthen education, technology, and shared vision through climate justice. As Climate Corps members build green energy technology and plant drought-resistant agricultural grains, perhaps they may also sow the seeds of peace.

TRANSPORT: Cargo Ships with Wings

Posted on September 12, 2023 by Building The World

**Will winged ships be the future of cargo transport?** Image: “Pigeons Flying” by Eadweard Muybridge, 1893. Public Domain. Included with appreciation.

Transportation contributes to global warming by use of fossil fuels. Electric vehicles are increasing in use while decreasing emissions; batteries needed to store and dispense electric power are easier to develop for smaller vehicles like cars or vans, even trucks. Airplanes are improving. Short-haul passenger travel has made some progress with electric aircraft, and United Airlines recently flew from Chicago, Illinois to Washington, D.C. on biofuel. Train travel is clocking faster speeds with lower emissions from innovations like Mag-lev and Hyperloop. But what about shipping?

**Container ship “Ever Given” stuck in the Suez Canal on 21 March 2021,** by Copernicus Sentinel Satellite. Adapted as photo by Pierre Markuse, 2021. Creative commons 2.0. Included with appreciation.

Maritime shipping moves 80% of all the goods manufactured and produced in the world economy. The industry emits one billion tons of CO2 every year – 3% of human-generated emissions. The industry grows every year: in 2021, 1.95 billion metric tons of cargo were shipped via container fleets. The biggest shipping companies include APM-Maersk, CMA CGM, COSCO, Evergreen, Hapag-Lloyd, and MSC; each receiving loads of TEUs (acronym for twenty-food equivalent unit, a standard of measure in the shipping industry). When a particularly large container freighter became stuck in the Suez Canal, attention was called to the shipping industry and its role in global transport, and emissions. Behemoth container ships are too large run on batteries, and solar panels are not the answer, either. What about wind?

Enter Pyxis Ocean. It’s a cargo transport ship, chartered by Cargill, that has been fitted with wings. Two sails made of steel, each 123 feet (37.5 meters) tall, set sail recently. The wing/sails are foldable, allowing passage under bridges. The vessel was retrofitted by BAR Technologies, Yara Marine Technologies, and Mitsubishi. While the ship still uses fossil fuel, wings use wind to reduce fuel consumption by 30%. Launched in China and sailing toward Brazil, Pyxis Ocean is an innovation worth watching. Cargill is an agricultural firm, transporting 225 million tons annually. Could this be the beginning of a new era in shipping?

**The earliest global trade was through ships with sails.** Image: “Two Danish Ships entering Portsmouth Harbour” by J.M.W. Turner, circa 1807-1809. Tate acquisition number N00481. Creative commons public domain. Included with appreciation.

The earliest global transport ‘supply chain’ was through ships with sails. Historic great fleets with complex arrays of sails are the stuff of legend, and art. Is past now prologue? Cargill/BAR/Mitsubishi/Yara received support from the European Union’s WindWings project. The aim is to retrofit existing shipping vessels with wings to reduce fuel use and therefore emissions. BAR’s Head of Engineering Lauren Eatwell, a lifelong sailor with Olympic experience as well as education in composite structural engineering, helped to pioneer the WindWing design. Cargill aims to save 1.5 metric tons of fuels per wing per day. With advanced fuels (think methanol), more cost and emission savings are full speed ahead. We are the water planet, and we will continue to traverse the globe with ships. Can the shipping industry take wing?

ENERGY/WATER – Congratulations! Pause on Deep Seabed Mining

Posted on August 22, 2023 by Building The World

**CONGRATULATIONS and thanks for voicing your support for pausing deep seabed mining**, might be the words of this ‘Dumbo’ Octopus, more formally known as Opisthoteuthis agassizzi. Image: “Dumbo Octopus” by NOAA, 2019. Creative Commons 2.0. Included with appreciation.

If you voted “yes” to pause decisions on deep seabed mining, your voice has been heard. The International Seabed Authority (ISA) agreed to extend discussions on guidelines for deep sea mining, and to develop clearer policy to protect the marine environment, until 2024, or maybe even 2025.

A proposal by Chile, Costa Rica, France, Palau, and Vanuatu, supported by other member States, overrode the “two-year rule” enacted by Nauru and The Metals Company to begin mining in the Clarion-Clipperton Zone (CCZ). The matter will advance to further discussion at the twenty-ninth session of the Assembly in 2024; some say debate could extend to 2025. There is time; you can become better informed and more involved.

**Palau is one of the signatories of the measure to pause deep sea mining advancement until further discussion**. Image: “Palau archipelago” by Lux Tonnerre, 2008. Creative Commons 2.0. Included with appreciation.

ISA revealed the decision in an August 2 report entitled “Just and Equitable Management of the Common Heritage of Humankind.” Part 04 of the report reveals the “Status of Contracts for Exploration in The Area.” These areas are the Clarion-Clipperton Zone (CCZ), the Indian Ocean, the Mid-Atlantic Ridge, and the Northwest Pacific Ocean. The areas are the focus for:

19 contracts for mining of polymetallic nodules (PMN)

7 contracts for mining polymetallic sulphides (PMS)

4 contracts for cobalt-rich ferromaganese crusts (CFC)

There are two kinds of ISA contracts: exploration and exploitation. Exploration contracts assess minerals present in the area and may include sampling, as well as testing mining technologies and ways to process mined minerals. Advancing to exploitation contracts would commence deep seabed mining. Contracts are sponsored by member states, and may include private enterprise partners. States currently sponsoring contracts include Belgium, Bulgaria, China, Cook Islands, Cuba, Czech Republic, France, Germany, Jamaica, Japan, Kiribati, Nauru, Republic of Korea, Russian Federation, Singapore, Slovak Republic, and Tonga (ISA Figure 12). While exploration may be carried out by presence and probing, as done by Alexander Dalrymple and James Cook using lead lines and sextants on voyages of the “Endeavor;” since the time of COMSAT, the deep seabed may also be mapped by remote sensors and satellites.

Don’t rest on your votive laurels. The deep sea, and its treasures, are shared possessions of all the world and its many inhabitants including fauna and flora of the deep. You help the world decide what will determine the “Just and Equitable Management of the Common Heritage of Humankind.” (ISA 2023) What are your views? What actions can you take this year, and next?

WATER: Lahaina – Help and Hope

Posted on August 15, 2023 by Building The World

“Lahaina Beach – West Maui” by D. Howard Hitchcock, 1932. Hawaii State Art Museum. Creative Commons 0: public domain. Included with appreciation.

Hawai’i may often be depicted in colors of blue water and green tropical plants. But now, Lahaina, on Maui, is charred brown. Lahaina lost lives: the total of fatalities in the worst fire in US history is still rising, already surpassing deaths in California’s Camp Fire of 2018 that killed 85 people and destroyed the town of Paradise.

“Fire hydrant flushing,” by photographer Lldar Sagdejev, 2011. Creative Commons 4.0. Included with appreciation.

While heat, drought, and wind created conditions for fire, Lahaina’s municipal systems might have made it worse. Hydrants, placed along city streets for emergency water access, produced little to help firefighters. Lahaina’s water infrastructure draws water from a creek and from wells underground. But when the ravaging fire melted delivery pipes, causing them to burst, losing precious water, those leaks, in turn, affected the pressure of the whole water system, including the delivery of water to hydrants.

Fire damage and lost acreage in the U.S. has tripled in the last three decades. Image: “Wildfires burned in the United States” by Our World In Data, 2020. Creative Commons 3.0. Included with appreciation.

As the climate warms, and droughts increase, wildfires may be more frequent. In 2022, seven countries’ capitals surpassed 40-year high temperatures In South Korea, 42,000 acres burned in a fire in Uljin. In Algeria, a fire in the region of Al Taref consumed 14,000 acres. In Argentina, Corrientes province suffered a fire that charred 2, 223, 948 acres.In the USA, the named McKinney Fire burned 60,000 acres. That same year, in the European Union, over 2 million acres burned.

Fire also damages essential infrastructure. Lahaina’s water system suffered damage; that’s not an unusual effect of fire. In Australia, when heat rose to 151 degrees Fahrenheit (66.3 Celsius) and winds gusted to 79 miles per hour (128 kilometers per hour), Snowy Mountains Hydroelectric lost some power when NSW grid links went down; 14,000 people lost electric power. Fire damaging water – the very element needed to quell flames – is not a new phenomenon. In 1633, famous landmark London Bridge suffered a fire that damaged its waterwheels, thereby preventing pumping water to stop the flames. In Lahaina, Hawaiian Electric equipment and infrastructure of Hawaiian Electric, serving 95% of the state’s residents, suffered damage to power lines. With electric and water system affected by the fire, Lahaina’s infrastructure proved to be a factor in the scope of the disaster. An early assessment of the cost of Lahaina fire damage: $6 billion. Lahaina is both a tragedy and a warning.

How can we protect buildings and essential infrastructure? Image: “Fire in Massueville, Quebec, Canada” by photographer Sylvain Pedneault, 2006. Creative Commons 3.0. Included with appreciation.

How can we protect people and property from fires developing from heat, drought, and winds? Here are a few ways:

Assess water systems to protect hydrants and pipes

Climate-proof power grids and essential infrastructure

Limit plants (avoid non-native) and vegetation near buildings

Strengthen regulations for construction materials, emphasizing cement, stone, or stucco

Require tempered glass in windows to reduce window blow-out that fans flames

Test signal systems and err on the side of caution when issuing warnings

It is true that preventive protective measures are costly. But post-fire rebuilding costs are 10 to 50 times suppression costs. Global predictions for climate-related wildfires may reach $50 billion – $100 billion annually by 2050. While the world surely needs to quell warming; meanwhile, directing funds and attention to prevention of future fire damage is important. This will be an area of significant innovation, applicable globally.

Lahaina’s fire was ultimately stopped by water. Flames expired when they had consumed vegetation (some non-native that burned faster) and buildings, until the blaze reached the ocean. People fleeing burning homes endangered their lives to save them by jumping into the Pacific waters. The water system of Lahaina must now be rebuilt. Can the waters of the Pacific help? Maybe. Seawater contains salt, corroding the very means of its conveyance. Moreover, salt water damages vegetation, buildings, and even fire equipment. In the future, desalination innovations may make it possible for coastal areas to use sea water for many purposes, including fire response.

CITIES: HEAT – Below

Posted on August 7, 2023August 6, 2023 by Building The World

**As above, so (much more) below! Cities can be 18F/10C hotter (0r as high as 20C) below, creating underground climate change.** Image: “Morning sunrise above Suwon Gwanggyo Lake with City in Background” by photographer Matthew Schwartz, 2016. Creative Commons 3.0. Included with appreciation.

“As above, so below,” goes the saying. Just one look at a large city’s skyscrapers and buildings will hint at the massive infrastructure below. But did you know that climate change, experienced by the occupants of those buildings, is also lurking beneath their urban landscape? Our cities are suffering under heat domes, but it is even hotter below.

**Machinery under buildings is related to “underground climate change,” a growing urban concern.** Image: “Underfall Yard Pumps” by photographer Blythe Varney, 2017. Creative Commons 4.0. Included with appreciation.

Problem: The technical term is subsurface heat islands, but it’s easier to think of it as underground climate change. Equipment below skyscrapers generates heat; subways and tunnels create conditions that increase warmth. Pipelines under the ground, even sewers, are sources of subsurface heat. Land around and below large structures changes when heated, triggering slight shifts in topography. Foundations begin to erode; tunnels weaken; train rails warp; retaining walls may show cracks, then collapse.

**Subway systems under major cities are one source of underground climate change.** Image: “Washington, DC – Farragut West Station, 2018” by photographer Tdorante10. Creative Commons 4.0. Included with appreciation.

Example: A study by Professor Alessandro F. Rotta Loria of Northwestern University placed sensors under buildings and transport infrastructure in Chicago, Illinois, noting that the ground below was measurably hotter than surface land (a difference of 18F/10C). Professor Rotta Loria studies subsurface urban heat islands, warning that “underground climate change can represent a silent hazard for civil infrastructure…but also an opportunity to reutilize or minimize waste heat in the ground.” (Rotta Loria, 2023).

**Underground climate change can weaken retaining wall**s. Image: “Wallstones Breaking” drawing by Dimitry Borshch, 2008. Creative commons 3.0. Included with appreciation.

Difficulty: Because it is out of sight, underground climate change is difficult to recognize – until a retaining wall breaks. Think of it as similar to the gradual change in an iceberg below the water: slow, relentless, and then tragic. Or a slow earthquake: not sudden – until it is.

**Chicago’s buildings are hotter underground by as much as 18F/10C.** Image: “Chicago Skyline” by photographer Jesse Collins. Creative Commons 3.0. Included with appreciation.

Scale Counts: The bigger the city, the more likely underground climate change is happening. The study cited above was conducted in Chicago: population 2.6 million (2022). The study performed simulations over 100 years: from 1951 when subway tunnels were built under Chicago’s downtown “Loop” to projections until 2051. It is not unique to Chicago. Some of the world’s megacities, with populations over 10 million, could suffer significant damage. Megacities are dense, encouraging high rise construction that may exacerbate underground climate change. Cities that are growing quickly may be particularly vulnerable. For example, the most populous city of Nigeria, and its former capital before the new capital of Abuja was built in 1991, Lagos is among the world’s top ten fastest-growing cities. Another city vulnerable to underground climate change? Tokyo, Japan: population 37 million.

**Dense, populous megacities may be the most vulnerable to underground climate change.** Image: “Oloosa Market in Lagos, Nigeria,” by Omoeko Media, 2018. Creative Commons 4.0. Included with appreciation.

Emerging Answers: There are two approaches – prevent waste heat underground, or use it. In the area of prevention: new urban building codes, especially for dense cities, will need to place more emphasis insulation and energy efficient design. But secondly, waste heat could be used as an energy resource. Geothermal innovations that capture waste heat from the subsurface can find a use for that energy. Innovations for use of waste energy will become an area of significant potential.

Above/Below: We tend to focus on mitigating climate change by addressing what we can see and feel. Noticeable effects are mainly above the ground. But there will also be great need – and opportunity for innovation – below. Is your city likely to experience underground climate change? What are some of the ways your city can measure, assess, plan to address, and even harness for beneficial use, underground climate change?
