Boston’s transport nexus, venerable South Station, has seen many a commuter step across its hallowed floors since opening in 1899. Terminus of public transportation on the Central Artery, South Station lit up when MIT students James Graham and Thaddeus Jusczyk demonstrated a piezoelectric floor with kinetic tiles generating both electricity and data in the transport hub welcoming 75,000 T-riders daily.

During London’s 2012 Olympics, some visitors marveled at London Bridge, and then headed for the Games, accessed via the West Ham Tube Station. There, a piezoelectric floor designed by Laurence Kemball-Cook, then a student at Loughborough University, generated electricity from footfalls of arriving visitors to illuminate the station. Kemball-Cook soon started a company called Pavegen Systems that designs floors for high traffic environments like sports stadiums.

Marie and Pierre Curie used piezoelectricity in their Nobel Prize work. The electric phenomenon had just been discovered by Pierre and brother Jacques. Image: “Marie et Pierre Curie” in 1900 in their Paris lab. Public Domain.
Piezoelectricity (a term coined by Wilhelm Gottlieb Hankel in 1881 from the Greek “to squeeze or press”) refers to release of an electric charge found in materials such as crystals or ceramics. A year before, Jacques and Pierre Curie discovered the effect using cane sugar, Rochelle salt, quartz, topaz, and tourmaline. Marie and Pierre Curie, Nobel Laureates (and the first married couple to win the prize jointly) used piezoelectricity in their work on radium with Henri Becquerel.
What if you could charge your phone by walking? University of Birmingham, UK, installed a kinetic floor that powers students’ phones and computers. Image: “Charging smartphone” by Santeri Viinamāki, 2016. Creative Commons 4.0. Included with appreciation.
Uses for electricity generated by kinetic flooring are varied. UK’s University of Birmingham found students were constantly having to charge their phones. When they installed a floor (designed by Pavegen), the steps students walked generated enough power for phone charging. Pavegen also developed a digital app with “redeem or donate” options for energy currency: users can claim benefits to special events or support causes. Coldplay’s Music of the Spheres World Tour (MOTS: 2022-2025) now travels with a portable dance floor composed of 44 kinetic tiles made from recycled plastic.

Wildfires are increasing in severity with drought. California began 2025 with a conflagration in the Los Angeles area accelerated by high winds. In 2024, across the United States, over 61,000 fires burned more than 8,000,000 acres.

Globally, wildfires observed by the Copernicus Atmosphere Monitoring Service (CAMS) not only destroyed land, particularly in North and South America, but emitted 1,940 megatonnes of carbon monoxide, and deadly particulate matter. While the first response to a wildfire is saving lives, and then homes and businesses, the impact on air pollution is also an important factor.

With climate change, planetary warming, and increasing drought, fires will be a problem well into the future. What are some ways we can defend and protect against wildfires?
Xeriscaping saves water and stops fire. Image: “Los Angeles Air Force Base xeriscaping” by AF_SMC, 2015. Public Domain.
Defensible Space: our modern day lawns are the result of medieval fire defense. Castles were surrounded by fields: in order to spot encroaching enemies who might attack or set fire to grasses and plants, lords of the manor required areas around the castle be scythed. Cut grass became an upper class symbol that gave us modern day lawns. But according to FEMA guidelines for wildland/urban interface construction, defensible space can be improved. Southern Nevada Water Authority recently passed the first ever permanent law against “non-functional turf” – no more lawns after 2027. Landscaping designers might offer xeriscaping, saving water and protecting against fire.

Housing Shortages and Urban Expansion: California leads the Western United States in building in locations with high risk for fire, but Utah is second, followed by Colorado and Arizona. Wildland/Urban Interface is the term: California is an example, building 10,000 homes in the last decade in areas prone to wildfire. Urban sprawl also leads to traffic congestion as workers commute into the city from far-flung locations in order to afford housing. Solutions to housing must be part of future municipal planning, particularly when new housing areas are developed in fire or flood zones.

Water Infrastructure: In times of drought, water scarcity can lead to difficult decisions about how to allocate water. California’s residential population uses only 10% of the state’s water: agriculture drains far more. Should crops like almonds that require large amounts of water be subject to special taxing?

Insurance: An estimated 16,500 properties have been lost so far, in the Palisades and Eaton fires that consumed 38,000 acres to date: the Kenneth and Hurst fires are yet to be tallied. The Insurance Information Institute reported some companies had stopped issuing new homeowner policies, responding to a California requirement that insurance companies must hold certain reserves. University of California Berkeley’s Center for Law, Energy, and the Environment observed that profitability for existing companies will be severely restricted. Some homeowners resorted to California’s FAIR plan, insurer of last resort, but even that resource is now threatened. Globally, the insurance industry is increasingly denying payouts for rebuilding in zones with repeated losses.
“London Bridge Fire of 1632” by unknown artist, circa 1660. Public Domain.
Building Materials: wood has been a preferred material for structures because of its strength and availability. But the history of London Bridge might send a warning: the span was crossed by timbers during Roman times. But in 1176 King Henry II selected Peter de Colechurch to construct, next to the existing wooden span, a stone bridge. London Bridge burned again in 1632. Today, roof coverings, siding, decks, and houses should be built with noncombustible or fire-resistant materials. Windows and attic vents pose vulnerabilities unless specifically protected, because once breached, these apertures can allow fire to enter a dwelling. Top five fire-resistant building materials are: fire-resistant glass for windows; concrete for structures, especially new formulations of Insulating Concrete Form (ICF); stucco made of Portland cement, sand, and lime; gypsum board for drywall; and brick or stone.

GUILDS, UNIONS, ILO – Unions go back to medieval times. When the feudal system changed to free independent skilled labor, craft workers moved to cities and banded together to form guilds. But when outsiders, non-guild members or not even industry professionals, began to own the companies that hired the workers, unions developed. (Brentano)
International Labour Organization (ILO) logo. United Nations. Public Domain.
The inclusive, and protective spirit of the guilds, and unions, may today be kept in the International Labour Organization (ILO). Founded in 1919 to bring together governments, employers, and workers of the Member States of the United Nations (ILO is its only tripartite agency), the ILO seeks to promote social dialogue among all three, with special attention to Sustainable Development Goals (specifically: SDG 8 regarding work and growth, SDG 10 reducing inequalities, and SDG for justice and peace).
Workers’ hours have been a constant theme in unions, labor, and rights. Image: “Animated clock” by Balti sahib, Creative Commons 3.0.
HOURS – With unions came working conditions. Work days could last as long as 10 hours, and the work week could be six days, until 1593 when Spain became the first nation to declare a law to limit factory and building workers to an eight-hour day. The Ordenanzas de Felipe II included an interesting aspect that applies to today’s emerging worker rights law: a mandatory break between morning and afternoon work periods was ordered – to avoid the sun’s heat. In the 19th century, Robert Owen proposed a day sectioned into three parts: eight hours of labor; eight hours of recreation eight hours of rest. The movement reached farther shores when stone mason workers marched from Australia’s University of Melbourne to Parliament in Australia to establish the law.
Both Peter and Matthew McGuire both advocated the establishment of a holiday to honor the craft and skill of workers. The first Labor Day celebration took place in New York City in 1882: both McGuires were present. Image: Maguire (McGuire) family crest, Creative Commons 3.0.
CRAFT AND SKILL – In the United States, the first proposed Labor Day holiday originally honored labor as art and the skills of craft. Peter J. McGuire, general secretary of the Brotherhood (a guild name that needed updating) of Carpenters and Joiners who was also the co-founder of the American Federation of Labor. McGuire proposed the idea of establishing a holiday to honor “those who from rude nature have delved and carved all the grandeur we behold.” (US Department of Labor 2024)
A second McGuire – Matthew – is also credited for the holiday. This McGuire, secretary of Local 344 of the International Association of Machinists, also proposed the holiday in 1882 while serving as secretary of the Central Labor Union of New York. A first Labor Day gathering convened in New York City in 1882: both McGuires were present. A second observation happened in 1883. In 1884, President Cleveland signed a law creating a national holiday to be called Labor Day, to be observed on the first Monday of the month of September annually.
Pullman Strike, Chicago, Illinois, US, 1894. Public domain.
RIGHTS – But in a twist of fate, President Cleveland signed that law in July 1884, just before an uprising of labor caused a national tragedy and forever changed the character of Labor Day. Worker rights for hours and working conditions arose in Chicago, Illinois on several pivotal moments. One involved the transport industry and the innovation of transcontinental rail. Chicago was a known rail center, and headquarters of the Pullman company. The cross-country rail industry created a market for overnight travel. Chicago’s Pullman company (formed by buying up old passenger rail cars and turning them into sleepers) employed “Pullman porters;” hiring practice discriminated racially and enforced extremely long working hour – 400 per month. At the trigger of the 30% layoff, and to protest working conditions and assert worker rights, Pullman workers walked out on strike.
Transcontinental rail established a new order, one that could be disrupted by striking workers with new power. Image: Map showing section of Transcontinental Railroad, 1883. Atlantic and Pacific Railroad, Chicago and Pacific Railroad, C.W. & C. Colton & Company, US Library of Congress. Public Domain.
STRIKE POWER – Travel stalled in 27 states from Chicago’s Illinois to the West Coast. Communications stalled across the country: at that time, trains carried not only cargo and people but the post including commercial transactions. Strikers knew well how to stop a rail car on the line; they halted – and derailed – the locomotive pulling a postal train. The collective voice was heard. But so were gunshots.
Pullman strike erupted into violence; workers overturned rail cars and Illinois National Guard fired shots. Illustration by G. W. Peters, Harper’s Weekly, Volume 38, 1894. Public domain.
VIOLENCE – With the country effectively shut down, President Grover Cleveland authorized the US Attorney General to enact an injunction against the striking workers. The result was an acceleration of the strike into a riot. Protesters derailed more train cars. Escalation into military action ensued when the Illinois National Guard arrived at Blue Island, a Chicago suburb, and used firearms, killing 30 people and wounding many others. This happened in July. Ironically, President Cleveland had just signed the bill, in June, declaring a new holiday to honor workers.
Haymarket Square, Chicago, circa 1905. Image from postcard. Public domain.
In 1886, Chicago again was the center for a gathering to promote the eight-hour work day, overtime pay, and fair hiring practices. Child labor was reported in some areas. Workers went on strike at the McCormick Harvesting Machine Company. Police were present, and one person was killed and others wounded when police opened fire. The next day, protestors assembled in Haymarket Square. Police were again present. Someone, it is still unknown who, threw a bomb; police began shooting. Seven officers died, several civilians, and many dozen people were wounded. The episode became known in the history of labor as the Haymarket Massacre or the Haymarket Affair. A campaign to find the bomber resulted in hunt for perpetrators and later in several hangings, one suicide, one prison sentence and a later pardon.
UNIONS AND PEACE – In ancient times, the Netherlands organized climate response unions to gather if a dike overflowed. Today, a proposed Climate Conservation Corps could involve unions in the shared effort that all professions must contribute to our common future. The voices of unions as part of the International Labour Organization might support cooperative vision. Because firearms and violence have been a tragic part of strikes such as Pullman and Haymarket, unions might take up the issue of gun violence. Could unions use their collective voice and global power to unite justice and rights with peace?

LABOR UNITES THE WORLD – Labor circles and unites the world in a connective, collective system of craft, rights, and honor. This month, in the United States, Labor Day finds 10,000 hotel workers striking to call attention to working hours and conditions. Political candidates and present leaders are appearing and speaking at rallies. The campaign for work and justice will always be new, and needed. Factory workers still labor in unhealthy and even lethal conditions; miners (in some locations, including children) suffer health and injury; health care workers endure long hours. Reparation for enforced labor, in some places continuing, still needs justice. Recently, new regulations on hours of outdoor workers during increased heat of climate change now address worker health, rights, and safety.
If you are reading this in a country that celebrates Labor Day today, make it more than just a long weekend. And, if you live in an area that honors workers at another time, perhaps we can all make September a month when we recognize the farmers whose harvest graces our tables, those workers who create seasonal goods and services, the health care professionals who offer fall influenza protection, the teachers that welcome students for a new year, the transport systems that bring us all to the places where we work and that special place we call home. This month, how will you honor craft, justice, rights – and the fruits of our individual, and collective, labor?

Minerals like graphite (and graphene) may be rewriting our energy future. Image: “Electromagnetic induction” animation by Ponor, 2005. Creative Commons 4.0.
Graphite may be one of the answers to the carbon transition. Carbon in its purest crystalline form, graphite is rewriting energy, especially in its related form of graphene. Graphite is basically thousands of layers of graphene. What are these two and why are they named after writing?
If you have ever taken a test or made notes with a pencil, chances are it is No. 2 “lead”. In fact, it is not lead (as was originally thought, hence the name) but made with graphite. Because graphite comes in a variety of options: H markings designate its hardness (2 or even 3 for a harder core) or B for blackness of resultant writing.
Graphite is commonly used in pencils. Some say the pencil was an early enabler of widespread education. Image: “HB pencils” by photographer Dmgerman, 2007. Creative Commons 3.0.
What is graphite and why it is called by that name? Around 1550, in Borrowdale, Cumbria, England, sheep farmers who discovered a large deposit of the mineral found it very effective for marking sheep, identifying those in their herds and flocks.
Graphite was originally used in Borrowdale, England, to write on lambs and sheep. Image: “Sheep, Stodmarsh, Kent, England” by photographer Keven Law, 2008. Creative Commons 2.0.
Writing on sheep soon expanded to centering this new material in casings of wood to be used as a writing instrument. We can credit Abraham Gottlob Werner for coining the term graphite (“writing stone”). Thus was born the pencil. It was so effective at writing, and so abundant in nature (along with wood to encase it), that some historians credit the invention of the pencil with the expansion of public education. No longer would a quill be needed.
Before graphite pencils, quills and ink were needed for writing. Image: “The Bookkeeper” by Philip van Dijk, circa 1725. From Gallery Prince Willem V, The Hague, Netherlands. Creative Commons0 1.0: public domain.
Graphite proved versatile. Resistant to heat, yet malleable, it came to be used in lining molds for cannonballs. It could be fashioned into a crucible, a container for mixing metals at high temperatures. Graphite became so important in England that it was controlled by the Crown.
Cannonballs may not be used in modern warfare, but persist in mythology. Here, Marvel Comics “Cannonball” from X-Men, 2007. Image: fair use. With appreciation to Marvel Comics.
Because graphite is resistant to heat, and also can conduct electricity, it entered a new era in the 1970s for use in batteries. Graphite is an excellent anode (the electrode of a polarized electrical device through which a positive current enters the device). Its partner, the cathode, is where current leaves the device. These words, too, were coined. In 1834, William Whewell and Michael Faraday discussed the need for a name. They decided upon the inspiration of nature, following the path of the sun. Anode was patterned on Greek for “ano = upwards” + “odos = the way” – it was a model of the sun rising. Cathode was from the Greek “kath = down” + “odos = the way.”
Anode and Cathode were named after the rising and setting of the sun. Image: “Sun Animation” by designer Sfls4309pks, 2018. Creative Commons 4.0.
Graphite is a dominant anode material in lithium-ion batteries. Manufacturers of batteries and related applications continue to develop innovations for graphite use. Graphite is so important in industry that more than 60,000 patent applications for graphite technologies were filed in the decade 2011 to 2021: China filed 47,000.

Generally, graphite is mined. Most comes from China, India, Brazil, Turkey, and North Korea; it was also once mined in the United States. World reserves of graphite can be found in Turkey, China, Brazil, but also Madagascar, Mozambique, Sri Lanka and Tanzania. Purity varies: Sri Lanka has deposits with a purity of 99%. Ride a Sri Lankan graphite mine elevator here.

Graphite can also be synthesized: Edward G. Acheson was the first to do so Like many scientific discoveries, it happened by accident. But the patent Acheson received in 1896 opened a new industry for synthetic graphite.

Graphite can be recycled, with the resultant powder used to amplify the carbon content of molten steel. Recovering graphite from batteries or lubricants (or the core of nuclear reactors) involves sulfuric acid curing, leaching, and calcination to separate reusable graphite. In current practice, recycling of the cathode part of batteries has been common, but less so the spent anode graphite. But with scarce new resource supply and environmental trends, regneration of spent graphite anodes from electric vehicle batteries will increase (Shang, et al., 2014). The global market for recycled graphite is still small: $45 million in 2021 projected to grow to $110 million by 2031 – maybe much more.
Graphite may be most valuable as the parent source of graphene, which is extracted from the mineral. Graphite is composed of layers with rings of carbon atoms that are spaced in horizontal sheets. Graphene is derived from Some herald graphene as the future of sustainable materials. It is used in applications as diverse as mobile phones and solar panels. It’s pure carbon and it is strong – more than 200 times stronger than steel. And it’s light – five times lighter than aluminum. It has thermal properties, it conducts electricity. In batteries, graphene could increase battery life by 10 times, shorten charging time. Because it is so light, yet powerful, graphene is ideal for batteries that power drones. Because it is heat resistant, graphene could lessen the danger of batteries overheating.

So, is graphene the same as graphite? No, but they are related. the International Union for Pure and Applied Chemistry (IUPAC) made the key differentiation. Graphite is three-dimensional. While scientists knew about it, graphene was difficult to isolate. In 2004, Andre Geim and Konstantin Novoselov succeeded at the University of Manchester. In 2010, they received the Nobel Prize in Physics. Their process involved pulling graphene layers from graphite. The Prize noted “groundbreaking experiments regarding the two-dimensional material graphene.” (Nobel Prize 2010) It should be noted that subsequent discussion revealed the omission of Philip Kim of Columbia University; Geim responded he would gladly have shared the Prize with Kim.
Identification of graphene from graphite merited the Nobel Prize in 2010. Image: “Nobel Medal” by photographer Klaviaturka, 2018. Creative Commons 4.0.
Graphite is the crystalline form of carbon. It comes in three forms: amorphous, flake, and vein. It can be found in coal and shale. Flake carbon has the highest carbon content : 85-98 percent. Vein carbon is rare. but pure carbon up to 99 percent (it is now mined in Sri Lanka). Back in the early days, graphite was burned but in 1779 it was found to emit carbon dioxide under combustion. So, is graphite part of the carbon problem? Perhaps. Graphite is the most stable form of carbon, but it can release carbon emissions during a process called spheroidisation during which carbon flakes are placed in a mechanical process that rounds the particles. It’s a process that improves anode performance, but some flakes are lost and produce emissions. Most carbon emissions associated with graphite, however, come from the carbon-based fossil fuels that power the processes of its manufacturing into products.

Because it is pure carbon, graphite can become coal, and could theoretically be used as a fuel. But it is so valuable in so many other applications, like batteries, that its future as a fuel is most unlikely and environmentally undesirable. But there is one other high value thing that graphite, under very high pressure and intense heat, could become – a diamond.

It’s driving the electric vehicle and renewable energy revolution, but nickel has vexed miners and chemists since the earliest days. In fact, nickel got its name because of its difficult nature. Nickel – from German “Kupfernickel” or “Old Nick’s Copper.” Miners who discovered nickel thought it was copper but were never able to extract copper from it. They named it after their term for the devil: “Old Nick.” In a side note, nickel’s etymology also gives us a favorite bread: “Pumpernickel,” perhaps because the devil enjoyed this dark loaf.

Despite its name as an American coin (the origin of the term is actually German), there is not much nickel found in the United States, although there is a mine in Riddle, Oregon that produced 15,000 tons (in 1996). That same year, Russian nickel mines yielded 230,000 tons, followed by Canada (183,000 tons), Australia (113,000 tons), and Indonesia (90,000 tons).Trading as a commodity, nickel’s pricing per ton ranged from 15,614 to 25, 076 in 2024. Metals like nickel are traded on the London Metal Exchange (LME).

Like cobalt, nickel can be found in the deep seabed. In fact, exchange prices – like those on the London Metal Exchange – for nickel and cobalt, are influenced by estimates of deposits located in the seabed. In particular, cobalt and nickel are inter-related, often found together. On land, their mining is known, although not often enough followed by recycling and re-use. Under leagues of water, the process is not tested, and is also contested.

Another place nickel may be found is in the sky. Asteroids, especially those categorized as M-type or M-class, contain iron and nickel. But the search will be long: only 8% of asteroids, like Lutetia (see in image below) are M-type.

Cobalt, nickel, and other minerals and metals that are critical for use in renewable energy are recyclable and reusable. Yet, the International Seabed Authority is reviewing contracts for nickel mining. Asteroid mining companies are also in the race. But nickel recycling may be a better bet and more certain investment. Nickel recycling has been expensive and difficult, requiring high heat and releasing toxic fumes. In former times, it may have seemed easier to obtain primary nickel (mined) than to pay for secondary nickel (recycled). Tax credits and rebates could help.

But innovation-leading companies including Aqua Metals in Reno, Nevada, USA, and ABTC, as well as the Nevada Center for Applied Research (NCAR) at the University of Nevada, Reno and Greentown Labs, may change the way we use – and reuse – nickel. Presently 68% of all nickel already mined is recycled, but 17% is still dumped in landfills. Will the recent Declaration of Metals Industry Recycling Principles help to make mineral and metal recycling the industry standard?

While fossil fuels are used up when combusted (leaving greenhouse gases), minerals and metals are not depleted because they only conduct and store energy. Minerals and metals can be recycled and reused. Have a nickel in your pocket? Be the change.
Baltimore’s Francis Scott Key Bridge disaster is a tragedy. You can help here and here.Image: ‘Cable stayed suspension bridge” by Wikideas1, 2024. Pubic Domain CC0 1.0. Included with appreciation to the artist and support for Baltimore’s families who have suffered loss.
The tragedy of the Francis Scott Key Bridge brings deep sorrow for those lost and injured, as the search for those still missing continued after the accident. The Baltimore bridge was slammed by cargo vessel Dali after the 984 foot (299 meters) ship lost power and could not avoid collision. A MayDay call was sent, but it was too late. Citizens in the area rushed to help, forming a human blockade to prevent oncoming traffic from entering the bridge access.

While using waterways for transport is an ancient idea, and has recently been championed by European transport experts as more environmentally beneficial, the size of cargo ships must be considered. Europe has 23,000 miles (37,014 kilometers) of waterways: using canals and rivers for cargo transport could reduce emissions from trucks. Presently, 6.5 million trucks deliver goods across Europe, while rail carries just 5% and rivers 2%. European port operator Haropa proposed rivers and canals as a means of cargo delivery. But when European canals, as well the American Erie Canal were built, and the bridges that span these waterways, cargo vessels carrying goods were smaller.

Now, the size of the average cargo ship is considerably larger. Ships that have problems can cause major trouble, like the container ship Ever Given that got stuck in the Suez Canal. In the first three months of 2024, cargo ships have hit bridges in Argentina, China, and the United States. Some would question if waterways, and bridges, are ready for the size of cargo vessels now used. The Port of Baltimore is the 11th largest in the United States. It is an important transport center, but what are the limits of the ships that traverse its waters? What safety measures need to be in place in the world’s ports? Coastal cities around the world are some of the most important ports. Baltimore is one; Boston is another. Will sea level rise threaten the safety of ports?

While the Francis Scott Key bridge was not structurally deficient (although there has been comment on its structural redundancy, a term for extra support that can compensate for damage preventing collapse, as well as pier protection) and was certified as completely up-to-code, too many of our spans are in need of strengthening. Bridges last about 50 years before showing problems. The age of the average bridge in the United States is 42. A study by the American Road and Transport Builders Association (ARTBA) revealed that 36% of U.S. bridges – 222,000 – are in need of repair. The total cost? $319 billion. How much is currently allocated? $3.2 billion.

Bridges were once, and remain, so important to city planning and security that in ancient Rome, only the Pope and a small cadre of bishops had the right to authorize a bridge. From that historic beginning, we get our word “pontiff” (Latin “pontifex” from “pons” (bridge) + “facere” (to do or make). Only the Pontiff of Rome could issue a bridge permit. In olden days of China, there was a bridge over which only the Emperor could walk.

Many transport historians might mark stages of civilization by connections formed via bridges. London Bridge changed the commerce of the city. Its span was the location of what may be one of the first shopping malls: retail stalls built along the structure paid rent that helped support bridge repairs. London Bridge is significant, too, for what was perhaps the first worker’s compensation plan, according to King John’s document of authorization to the Lord Mayor of London.

Bridges can raise the spirit: the Brooklyn Bridge has inspired more poetry than any other bridge in history. Hart Crane’s “To Brooklyn Bridge,“offers reflections upon the span. The bridge is also connected to philosophy: it began in the mind of John Roebling who contemplated teachings of his professor at the Royal Polytechnic in Berlin: the philosopher Hegel. It was one of Hegel’s theories that gave Roebling the idea: it came to him in a flash during a hike in Bamberg. He sat down on a rock and sketched what would become the Brooklyn Bridge.

European Union bridges tend to be on the older side: many were built as part of the Marshall Plan, just after World War II in the mid 1940s. Germany’s Leverkusen Bridge developed concrete cracks and was closed to heavy vehicles in 2012. In 2018, Italy’s Morandi Bridge connecting Genoa to France collapsed in a drenching rain storm. Built with only one pair of cable stays to support each section, vulnerability may have been inherent in the design.
Will bridges, many built in earlier times for different conditions, withstand the stronger storms of climate change? Britain’s Tay Rail Bridge washed out and collapsed in a strong storm in 1879. Image: Tay Bridge Catastrophe, 1879. Image origin: public domain, author unknown.
Climate change and attendant extreme weather, including intense winds and storms creating waves and floods, may affect bridges. In areas with drought subject to wildfire, bridges might need protection in parts of the span that may contain fiberoptic cable. Concrete may seem strong, but it cracks at 500 degrees Fahrenheit and melts at 2,500 degrees. Innovations like “First Line Fire Blankets” can be applied to bridges, power cables, and even gas pipelines. Make of E-glass fiber that resists thermal conductivity, “fire blankets” can be retrofitted to protect critical infrastructure.
China’s Belt and Road Initiative (BRI) is building many new bridges. Are there opportunities for innovation that can respond to climate change? The Mohammed VI Bridge, Morocco, was a BRI project.

Older bridges may be supported by vigilance and retrofitting. Newer construction has opportunities for innovation. China’s Belt and Road Initiative, connecting Asia all the way to Africa and Europe, may tally $8 trillion. Financed in part by loans to countries that agree to the building of bridges, ports, roads, railways, China’s debts-owed increased 20% since 2013 when the project launched. More than 68 countries have signed on to participate in the project that will involve 65% of the world’s entire population. Bridges in the plan include the China-Maldives Friendship Bridge, Maputo Bay Bridges in Mozambique, Mohammed VI Bridge in Morocco, and the Peljesac Bridge in Croatia. Decisions made about bridge design, strength, maintenance, and technology may determine the future of the much of the world’s connectivity over water, and also over terrain needing aerial bypass. What are some ways bridges can be improved?

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.

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.

But did you know that glitter and sparkle usually gleam with plastic coatings? Sparkle – greeting cards and packaging, holiday ornaments, festive dresses and party attire – may be made from chemicals that are toxic and largely unregulated. It’s an area of plastic pollution that we rarely consider.

Hang an ornament on a holiday tree – it may glow in the lights but later sprinkle some coating dust. A child may open a card shining with glitter, and later wash their hands before enjoying holiday treats. Sparkle left on little fingertips may wash down the drain and into the water supply. Teens can twirl to holiday party music but their festive attire might shed a sequin or two. Dance floors are swept, and mops are rinsed. Sequins, sparkle, and glitter can flow into the water supply.

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.

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.
