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.

Geography is destiny, some observe. Timing accelerates the pace. And now, climate might be changing both. It is Mexico’s time?
Mexico’s Isthmus of Tehuantepec connecting Pacific to Atlantic might complement the Panama Canal, and offer a number of opportunities for transport. Image: “Isthmus of Tehuantepec” by Kbh3rd, 2007. Creative Commons 3.0. Included with appreciation.
Mexico’s Isthmus of Tehuantepec, spanning the Pacific Ocean from Oaxaca to the Atlantic Gulf at Veracruz, has always fascinated visionaries who could see a highway, a railway, or a canal opening a transoceanic route of 188 miles (303 kilometers). Archival records show 16th century sketches of a connection. In 1811, a canal was proposed by Alexander von Humboldt who had traveled to the isthmus from 1799-1804: he also proposed another connective site that is now the Panama Canal. The route chosen by von Humboldt made clear the advantage of geography that can offer connection.

Macro engineering needs the right time and the right leader. The Channel Tunnel, linking England and France, had been envisioned by Napoleon, resisted by General Wolseley, but finally achieved in a design initiated by Frank P. Davidson along with a team of diplomats, engineers, and financiers: it is now the site of Eurotunnel.
Not everyone seeks closer connection. General Wolseley, seen here riding the fleeing lion, opposed the Channel Tunnel. Image: F. Graetz, 1885, from Puck Magazine. Public Domain.
Many tried to optimize the connective advantage of Mexico’s Isthmus of Tehuantepec. Mexico’s President Anastasio Bustamante proposed an 1837 plan for a railway. In 1842, the government (provisional) of Antonio López de Santa Anna granted José de Garay a fifty-year toll collection privilege in return for a survey leading to construction. (A similar provision was granted to Ferdinand de Lesseps who then built the Suez Canal.) When Porfirio Díaz, who hailed from Oaxaca, rose to the Mexican presidency, he inaugurated the first operation of the Railway from the port of Santa Cruz, carrying sugar from Hawaii. Six years of success ensued: 850,000 tons of cargo traversed the isthmus.
Railway won: Mexico launched the first railway in 1850. More would follow. Image: Announcement of Mexico’s first railway, 1850. Public Domain.
But then, in 1914, disruptive new technology happened: the opening of the Panama Canal. Isthmus rail traffic plummeted by one third; the next year, by 77%. Panama was shorter (just 40 miles or 65 kilometers), easier, and more cost effective because cargo loaded on a ship could remain onboard the same vessel that would carry it on to global ports. As many as 32 -37 ships passed through the Panama Canal every day – in just 8 hours. The Panama Canal widened the route; container ships grew in size and capacity.
Panama Canal, NASA image, 2002. Public Domain.
In 2023, a new situation threatened the Panama Canal: climate change. Drought threatens the region. The waterway, widened to accommodate ever-larger ships, may no longer support the heaviest behemoths. Limiting the number of ships per day began in 2023. If drought is severe, ships have to wait offshore for longer (and more expensive) periods; some buy their way up the line. Image below shows ships queuing up to traverse the Canal in 2023.
Enter Mexico. Observing an opportunity, the government began modernization of the Tehuantepec Railway and Oaxacan port of Salina Cruz. New tracks, re-laying of supportive basalt, advanced welding improved the railway. Construction of a breakwater outside the Salina Cruz strengthened the port. A new name was the cap that would announce a global vision: Corredor Multimodal Interoceánico (Interoceanic Multimodal Corridor). The railway is a centerpiece, both historic and futuristic. But much more is planned.
Railway is central but much more is planned. Image: Logo of Ferrocarril Interoceánico, CIIT, 2024. Public Domain.
The project will include a trans-isthmus pipeline connecting the two ports. In response, Salina Cruz will host a liquified natural gas (LNG) plant; that gas will then power ten new industrial parks. Businesses signing on will reap tax breaks for meeting job creation goals. Mexico’s commitment to natural gas expanded the network of pipelines nationally by 50% in the past decade; yet the South and Southeast receive less of that energy. Along with LNG, an existing oil refinery will turn residue into additional petroleum increasing the fossil fuel production by 70,000 barrels. In an area of the world were solar, wave, and wind may offer more environmentally sustainable opportunities, some question the direction of investment. But new partners like Copenhagen Infrastructure Partners will pursue green hydrogen, as well.
Some of the businesses moving to CIIT industrial parks may include those producing green hydrogen. Image: “NGC 604, ionized hydrogen in the Triangulum Galaxy” by Hui Yang, University of Illinois and NASA, 1995. Public Domain.
While a canal is not planned, cargo ships are invited to offload their cargo on the Pacific side, carry the containers across the railway stretch, and then re-load on the Atlantic side, probably to a partner vessel. With drought compromising the Panama Canal, Mexico may attract maritime shipping traffic, perhaps picking up 5% of Panama’s commerce. That would be a small percentage of a big number: in 2023, the Panama Canal’s revenues reached $4, 968 billion.

In all of the activity initiated by the Corridor, as it is known in English, and its potential to offer opportunity to southern Mexico, not everyone is sanguine: the First Nation and indigenous communities have expressed concern. Zapotec leaders won a lawsuit protesting land purchase for one of the planned industrial parks. Land payments also troubled a Zapotec activist who had protested the distribution of the funds: when he was found dead, such violence raised more concern – and fear. Human rights violations began to be raised. Mixe community leaders blocked progress on their section of the Railway: arrested protestors were released in response to demands by the National Indigenous Council. Indigenous concerns include disturbance of agricultural soil health and biodiversity.

Hosting the Olympics is both a financial danger and an opportunity for upgraded infrastructure. When Tokyo opened the 1964 Olympics, a new transit system debuted. Shinkansen, Japan’s famed train system, was completed just 10 days before. Timing was ideal: the new train line was profitable from day one, according to financial analysis by Japanese historian of technology Hoshimi Uchida. After the Olympics, Shinkansen expanded its reach: in 2022, there were 16,347 miles (27,245 kilometers) of tracks for trains carrying 382 billion passengers.

But past performance is not a guarantee of future profits. When Tokyo opened the 2020 Olympics (held in 2021 due to the global pandemic) there were no tourists to ride the rails. Hosting was heroic but unprofitable, costing $20 billion. Athens hosted in 2004, building a stadium that not only racked up debt but, some economists state, may have ushered in a financial meltdown. Rio 2016 featured Gisele Bündchen strolling the opening ceremony to “The Girl from Ipanema.” But the city later had to sell off the newly-built Olympic Village at a financial loss. Looking at the numbers from past Olympics, Denver, Colorado bowed out of the running for the 1976 winter Games. Is hosting the Olympics worth it?
Barcelona improved urban infrastructure during its hosting of the Games. Image: “1992 Summer Olympics” logo. Included with appreciation.
Barcelona emerged, in 1992, as a model of success through Olympian planning. New beaches, new transport including rail and a new airport, new telecommunications systems were so effective that a new term in architecture and urban planning emerged: “the Barcelona Effect.” London’s 2012 Olympics proved a new environmental technology: the renovated West Ham tube station offered renewable electricity created by movement of people crossing floors that lighted the entire metro station. Laurence Kemball-Cook, then a graduate student at Loughborough University, designed the technology plan and later formed PaveGen to offer electric floors to offices, hospitals, schools, and other buildings (including dance clubs) with ample foot traffic.

Will Paris 2024 be a success? Some see renovations in Seine-Saint-Denis – a cluster of 40 small towns – as a means to improve an area plagued by joblessness and crime. After the Games, the area may emerge reborn as a “mixity” of residential and business activity: 40 architects who worked with central planner Dominique Perrault will see if that vision endures. Some worry displaced residents could return only to be priced out. Sustainability is part of the plan: seats for an aquatic center are made from recycled plastic bottle caps collected by children in Seine-Saint-Denis schools. (Kimmelman 2024)
Among the many innovations Paris will bring to the 2024 Olympics is an underground cooling system that will keep athletes comfortable amid the rising heat levels related to climate change. The water-cooled (recycled) technology, part of the Paris vision to be carbon-neutral by 2050, is based on advanced geothermal technology.

Nickel is critical to the renewable energy revolution. Image: “Section of pure nickel accretion,” by Images of Elements, 2009. Creative Commons 3.0. Included with appreciation.
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.

.Nickel is valuable for its ferromagnetic properties: it is one of four with such powers. The others are cobalt, gadolinium, and iron. Over 60% of world nickel production makes its way to becoming stainless steel.

Nickel was at one time so abundant that in 1881, a coin in Swiss currency was made from pure nickel. In the United States, the coin called the “nickel” was introduced in 1857, but it was made with nickel alloyed with copper.

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.
Nickel and cobalt are both targeted for deep seabed mining: contracts are soon to be defined. You can vote your opinion here. Image: “Deep seabed mining schematic” by G. Mannearts. Creative Commons 4.0. Included with appreciation.
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?

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.

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.

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.

Can macro infrastructure links offer a path to peace? Diplomat Ferdinand de Lesseps had long dreamed of “piercing” the isthmus, and sought the concession from Mohammed Pasha al-Said, a childhood friend whom de Lesseps first met when living in Egypt with his father, French consul in Cairo. Accounts reveal the future pasha very much liked the breakfast cereal served in Ferdinand’s house, and the two became fast friends who both enjoyed horse riding. In fact, later as adults, they shared a dare to exhibit horse riding skills to jump a particularly high fence: the prize would be permission to build the Suez Canal. Land rights were spelled out, construction began: the route would link two entrances – one from the Mediterranean, the other from the Red Sea.
Ferdinand de Lesseps built the Suez Canal, and tried to later build the Panama Canal. “Caricature of Ferdinand de Lesseps by André Gil, 1867. Public Domain. Included with appreciation.
Ten years later, on 16 November, 1869, the Suez Canal opened with a marine parade of 65 ships from nations worldwide. Giuseppe Verdi composed Aida to honor the Suez Canal’s opening. In a quirk of irony, the costumes being prepared in Europe were delayed in shipping so the opera debuted the following year.

Friendship and international understanding graced the project – in spirit and in letter of the law. Khedive Mohammed Pasha al-Said and Ferdinand de Lesseps wrote and signed the founding agreement that called, in article VI, for “tariffs of dues for passage …(which) shall be always equal for all nations, no particular advantage can ever be stipulated for the exclusive benefit of any one country.” That principle of open access to all was legalized in the international Convention of Constantinople of 1888 in article I “in time of war as in time of peace, the canal shall never be subjected to the exercise of the right of blockade.”

In December 2023, several commercial vessels bound for the Mediterranean diverted from the Suez Canal route to avoid danger. Because the 120 mile (192 km) canal is the fastest sea route between Asia and Europe, it is the preferred passage. For example, a ship from the Mideast Gulf bound for Rotterdam, Netherlands would travel 6,436 nautical miles via the Suez Canal but 11,169 nautical miles taking the longer route around Africa. Since December, more ships have diverted. Portwatch, study group of Oxford University and the International Monetary Fund, reported Suez Canal traffic is lowest since 2021. Shipping rates, during the diversions, have tripled. Tesla idled a factory in Germany because shipping delays caused supply chain problems. But, more concerning to many is the issue that the Suez Canal was – and is – specifically a path to peace.
Can the Belt and Road Initiative’s many links be inspired to form a path to peace? Image: “One belt, one road” by Lommes. Creative Commons 4.0. Included with appreciation.
The Suez Canal’s Firman and subsequent Convention specifically dedicate the route to be open to all nations equally in time of war as in time of peace. Major transport routes, like the Suez Canal, represent both trade passages and potential paths to peace. How will such dedications affect the future of the Suez Canal, and also developing links such as those in the Belt and Road Initiative? Can macro infrastructure links, like the Suez Canal, serve as a path to peace?

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.

While many animals (and a few plants) move around, humans may be the only species that builds roads, ships, and aircraft to do so. Human history can be traced by modes of transport: carts and wheels, ships and sails, trains and rails, tunnels and tubes, roads and vehicles, aircraft and wings, rockets and boosters. The ancient Silk Road, emanating from China around 206 bc, running 4,000 miles (6,437 kilometers), was one of the first extended paths over land. China’s Grand Canal connected to the sea via one of the world’s first inland waterways. Transport is about connection: ancient China achieved both land and sea routes that resulted in cultural and economic exchange.
In 2013, China announced the Belt and Road Initiative. Now, in 2023, here is a map of the project. “Topographic map of the Belt and Road Economic Corridor and pathway cities” by graphic artist, 18 October 2023. Creative commons 4.0. Included with appreciation.
One decade ago, China announced what some call Silk Road 2.0; its formal name is the Belt and Road Initiative (BRI). This week, representatives from nearly 150 countries met in Beijing to consider next steps. One agenda item: debt. China has reportedly financed airports, bridges, hydroelectric facilities, pipelines, ports, and roads in extensive world locations with an understanding that the receiving country would pay back loans and share user fees. There have been criticisms, as well as defaults and delays. Nepal’s new Pokhara Airport opened with a big price tag but as yet small revenue. China recently restructured debt with Argentina, Sri Lanka, and Zambia, among others. Not everyone is staying in the program; Italy had joined but is now trying to leave. But some countries and their leaders are decidedly there: Russia’s Putin was at the meeting, so was Haji Nooruddin Azizi, a minister of the Taliban. (Cash 2023)

Perhaps in response to concerns involving environmental and justice concerns, China launched the 2021 Global Development Initiative to promote “economic and social development” with a funding deposit of $10 billion. The total BRI extension in loans and grants is estimated at $1 trillion.
The Belt and Road Initiative has both pro and con issues. Image: “Plus, Minus, and Equality Signs” by graphic artist Sa-se. Creative Commons public domain. Included with appreciation.
While debt is a concerning issue (some say it is a con in the word’s two meanings) so is pollution: China’s overseas fossil-fuel power plants emit 245 million tons of CO2 annually. Another factor is land use change, with further environmental damage and loss of biodiversity, especially to land that is the home of original, indigenous people. However, there may also be pros. China has extended $500 billion in funding that some say could improve the infrastructure and industrial capabilities of some areas that desire growth but may have had challenges getting funding. From any angle, the Belt and Road Initiative is macro and global.
The Belt and Road Initiative may soon circle the world. It is one of the most important macro projects in history. Could the BRI be an opportunity for renewable energy, sustainable water, and perhaps even a new understanding of our interconnected world? How can you get involved to make it so?

The scope and span of the BRI make it one of the most significant agents in climate. The sheer volume of concrete, for example, could influence the environment: what if the BRI instituted a policy regarding the use of concrete as a carbon capture and containment? Ditto BRI’s energy use: as a leader in solar, could China favor renewable technology in BRI projects? BRi may be the biggest and most impactful construction project in history. We need to pay more attention. How can we influence climate and justice decisions? Want to know more? Start here, or here.
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?

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?
