It’s About Time

When Wordsworth talked about the magic of a “spot of time,” the poet may not have imagined what digital challenges would be required by the adjustment of modern clocks to the world’s slightly irregular rotation. June 30, 2015, will have one extra second. We owe thanks to Sandford Fleming, surveyor for the Canadian Pacific Railway, who first suggested universal time standards. The International Prime Meridian Conference, held in Washington, DC, endorsed and inaugurated a worldwide system of time zones. What will you do with your extra second of time?

It’s All in the Timing

The Canal des Deux Mers was not a new idea by Riquet’s time, although he perfected it. The Archbishop of Toulouse headed a special commission chartered by King Henry IV (1553-1610) to study feasibility of a canal linking the Atlantic and the Mediterranean. Henry IV was following a line of similar visionaries. Even Charlemagne wanted to build the canal. There is evidence of ancient Roman emperors trying to engineer the route. Charlemagne, to be fair, didn’t have the technology. But Riquet was able to conquer a rocky patch near Beziers by blasting a tunnel – measuring 157 meters (515 feet) long, 6.7 meters (22 feet) wide and 8 meters (27 feet) high – with black powder. It was one of the earliest uses of explosives in subterranean construction.

CITIES: Dangers in Deltas

New Orleans, Louisiana, USA. “KatrinaNewOrleansFlooded” by Kyle Niemi, U.S. Coast Guard, 29 August 2005. Image: wikimedia commons.

New Orleans, Louisiana, USA: it’s an unprecedented situation. New Orleans, a city on the Mississippi River Delta, is under threat. The river, normally about 7 feet high in the summertime, sits presently at 16 feet, the result of spring flooding along the waterway. Add to that a virulent storm barreling towards the city, driving a surge of 2 to 3 feet. If so, the river may crest at 17 feet. On land, there may be as much as 10-15 inches of rain from the storm, a dangerous followup to the 9 inch downpour that inundated the area the same week. Storm storage, high rivers, and rain – it’s a deadly combination. Delta cities, like New Orleans, may be in peril with climate change.

Cities, throughout history, have been built on coasts, offering access to trade through ports and waterways.  Singapore may be the quintessential city upon the waters, developed as one of the first Specialized Economic Zones. New York (and Brooklyn) became leading business centers when their place on the Atlantic Ocean became linked to inland towns, the the Great Lakes, through the Erie Canal. But now, rising seas, threaten coastal cities. In 2019, the Northeast Atlantic will experience a 140% increase in coastal flooding, compared with two decades ago. Worse still, the Southeast will suffer a 190% flood increase, according to a report by the National Oceanic and Atmospheric Administration (NOAA). And that’s just the USA.

Worldwide, cities are sinking and seas are rising; Jakarta, Indonesia may suffer some of the the worst effects of climate change; Indonesia’s capital might need to relocate. According to the World Economic Forum Global Risk Report 2019, 90% of all coastal areas in the world will be affected by climate change; some cities will combat sea rise 1/3rd above mean level. The bigger the cities (more heavy buildings), deeper sinking.

Delta cities, like New Orleans, are in danger; the list includes:

DELTA CITES ENDANGERED BY SEA RISE:

Dhaka

Guangzhou

Ho Chi Minh City

Hong Kong

Manila

Melbourne

Miami

New Orleans

New York

Rotterdam

Tokyo

Venice.

Source: Muggah, 2019. World Economic Forum 2019 states “Even if we keep global temperatures from rising more than 2 degrees centigrade by 2050, at least 570 cities will be damaged.” That means people, drinking water and sanitation, mass transit, power, roads, homes, businesses, hospitals, schools.

It’s a sad business but a big one: coastal flooding could threaten 2 million homes in the United States, worth $882 billion. Worldwide, rebuilding or relocating coastal cities will take cause spending of $100, 000 Billion – per year. Is there any hope? Some historians observe that change and innovation  often are the result of crisis, citing examples as diverse as the Roman Aqueducts in response to a water crisis when the Tiber became not only polluted but endangered by terrorism (a threat of an enemy poisoning of the city’s water supply) to the intense research and development of the Manhattan Project resulting in the harnessing of Atomic Energy. Today, we face a similarly serious threat: will innovation save the day, or the century?

Rising seas, increasingly intense storms and hurricanes, are among forces eroding coastal cities, like New Orleans (or Jakarta). Saving sinking cities will demand significant innovations in urban harbors and cityscapes; cities with canals may lead the way to a better future. According to Henk Ovink, Special Envoy for International Water Affairs for the Netherlands and team leader of Rebuild by Design, “Worldwide, water is the connecting issue, the number one global risk and the opportunity for comprehensive cultural change.”

WATER: Cheers (from Cheerios)

Cheers! Can pubs offer a toast to public service? Image: “Weizenbier” by photographer Trexer, 2005. Wikimedia.

Food waste: it’s a world problem; more than 350,000,000 tons of food were lost or wasted so far, this year. Food trashed by the United States + Europe could feed the world (three times over). And, it’s not just food, but water, that is lost: food waste is responsible for 25% of the USA’s water use. But what if food waste could be transformed by the alchemy of brew?

Seven Brothers, a brewery in Manchester, England, makes rejected breakfast cereal (flakes too small, too large, for standardized manufacturing and therefore considered not right for the box) into craft beer. Like Corn Flakes?  You might appreciate “Throw Away I.P.A.” or if Coco Pops were a childhood favorite, you might re-aquaint yourself with a grown-up version in a dark stout, with chocolate overtones. Working with Kellogg’s, Seven Brothers receives 5,000 tons of deselected cereal flakes per year. Prefer toast? Try Chelsea Craft Brewing Company in New Oak for “Toast” made from left-over bread served at the screening of “Wasted! The Story of Food Waste” produced by Anthony Bourdain.

David Marks, Edward Spang, and other engineers and scientists who study the Water-Food-Energy Nexus report that 80% of the world’s water, 40% of the world’s land, and 10% of the world’s energy goes to food. Yet 1/3rd is wasted. Of course, brewing is just a very small response to food waste, but it’s a notable achievement. Should your next pub be chosen for its public service? Cheers!

TRANSPORT: Ask Alice

Alice: electric and ready to fly. Image: Eviation and Wikimedia.

Alice is a bit unusual looking. But she may be just what the world is looking for. The name, given to a new aircraft build by Eviation, Alice is a plane powered by three rear-facing push-propellers. It’s electric, and it promises to transport nine passengers, and two crew, at 276 mph (440 km/h) for 650 miles. Eviation, located in Israel, may be soon flying between Boston and Hyanis; Cape Air has ordered a number of Alice aircraft. The market for short-range air travel is considerable, but environmentally questionable. Alice may change that: using electricity. It’s also cheaper: using conventional fuel, 100-mile flight costs $400; with electricity, $8-$12: overall cost per hour is estimated at $200. The market is developing quickly. MagniX is working with Vancouver’s Harbour Air to electrify their fleet. Rolls Royce, Airbus, Siemens, and United Technologies are all working on electric aircraft; Zunum Aero, backed by Boeing, uses a French engine from Safran; EasyJet is using Wright Electric for potential flights from London to Amsterdam.

TVA logo: Image: thanks to Social Welfare Library, Virginia Commonwealth University.

When electricity first began to be used for commercial and consumer applications, the Tennessee Valley Authority (TVA) built a new town just to demonstrate the new power source for refrigerators, toasters, and porch lights. The Town of Norris was the Consumer Electronics Show (CES) of its time. Now electricity will see a new era, as battery storage improves through innovation. According to UBS, aviation will soon move to hybrid and electric aircraft. Zero emissions; cheaper; quieter – it’s an answer to the environmental and financial costs of regional travel. Electricity may be looking up: go ask Alice.

ENERGY: Net Zero = 10 Million Jobs

“Wind power plants in Xinjiang, China” by Chris Lim, from Windmills in China series, 2005. Image: wikimedia.

Nations, and industries, are steadily reducing carbon emissions;  the June 2019 European Union (EU) meeting  signaled progress. Finland and Norway have resolved to achieve energy net-zero (state where input and output result in a zero balance) by 2035; others pledged 2050. The COP21 Paris Agreement advocated all signatory countries (over 190) reduce greenhouse gas emissions by 40% from 1990 levels by 2030. Recently, Antonio Guterres, Secretary-General, urged the European Union to cut beyond that to 55%. Contributing to that goal is the phasing out of burning coal, and terminating approval of new coal-fired power plants after 2020. European Union nations failed to reach agreement on net zero by 2050; they did agree, however, to study ways to achieve that goal. One stopping point: some EU nations are more dependent upon fossil fuel systems; for example, Poland relies upon coal for 80% of its energy and many of its jobs.

“Installing Solar Panels,” Oregon Department of Transportation, 2008. Image: wikimedia

Energy Jobs: Renewable energy jobs are quickly growing and may soon overtake fossil sources. In a report by Climate Nexus, in the United States, “more people (over 3 million) work in wind, solar, efficiency and other clean energy fields than are employed as registered nurses and just shy of those working as school teachers.” Globally, people working in renewable energy reached 10 million in 2017 and continues to grow, attracting investment in technologies like solar photovoltaic. Hot job markets? By 2026, wind technician jobs will increase 96% and solar installer positions will grow 106%.

Energy innovations have always stimulated investment and jobs. The Tennessee Valley Authority was both a federally-owned electricity utility that served seven states, as well as a regional employment program: 9,000 people were hired in the first year. Will the TVA divest its 8 coal plants? There are also 30 hydroelectric facilities, 16 natural gas plants, 3 nuclear powerhouses, 14 solar energy sites and one wind energy farm. It’s still the biggest power campus in the United States. Also noteworthy: the muscle shoals sound.

Migrants invited to Australia to work on Snowy Mountains Hydroelectric also helped to build a new nation. Image: “Sydney Opera House” by Steve Collins, 2011: wikimedia.

Snowy Mountains Hydroelectric hired 100, 000, recruiting locally in Australia and also inviting war-displaced migrants to move for work and opportunity: “You won’t be Balts or Slavs…you will be people of the Snowy!” promised Sir William Hudson, first commissioner of the project. As renewable energy grows, the world may experience improvements in climate, innovation, migration, and employment.

WATER: antibiotics on tap

Pills of antibiotic cefalexin. Photographer: Sage Ross, 2014. Image: wikimedia commons.

Feeling sick? It may the drugs you just took when you drank a sip of coffee or a glass of water. Affecting not just humans but aquatic life, medications are entering the water as fast as plastic – they’re just harder to see.

Antibiotics have been found in 65% of over 70 world waterways tested. For example, a site in Bangladesh showed Metronidazole present at levels 300 times the safe limits (20,000 to 32,000 nanogram per liter (ng/l) guidelines set by AMR Industry Alliance). The most frequent contaminant? trimethoprim found at 301 of 711 river testing sites. Most prevalent antibiotic found at dangerous levels: Ciprofloxacin, in 51 of the 72 countries tested.

Chao Phraya River Drainage Basin. Image: wikimedia.

Rivers all over the world show similar results: Chao Phraya, Danube, Seine, Thames.  Some areas of the world suffer infected water more: Bangladesh, Ghana, Kenya, Nigeria, and Pakistan ranked highest of sites monitored. In general, Asia and Africa frequently exceeded safety limits for antibiotics but problems were also found in Europe, North and South America. In other words, it’s global.

Of course, antibiotics save lives. But that’s just the problem: growing global resistance to antibiotics, anti fungals, antivirals caused 700,000 deaths yearly due to drug-resistant diseases, among them tuberculosis. The United Nations’ Interagency Coordination Group on Antimicrobial Resistance predicts that by 2030, over one million people will die every year due drug-resistant diseases.

PROBLEMS: Individuals are in no small part responsible: a study in California revealed half of all medications are discarded, often into the water supply. Another problem: even if we don’t intend to, individuals deposit drugs into the water supply.  People take a lot of drugs, both prescription and over-the-counter; our bodies metabolize only a percentage of the intake, excreting the rest into wastewater systems. And then there are the larger systemic depositors: hospitals try to return unused drugs to manufacturers obtaining a credit or at least assured safe disposal, but care and nursing facilities may not have such arrangements. Certainly drug manufacturers generate highly concentrated waste; downstream of a New York State pharmaceutical manufacturing plant, antibiotic concentrations showed levels 1,000 times higher than normal. And then there’s agriculture: poultry and livestock farming are responsible for two trillion pounds of animal waste filled with the hormones and antibiotics fed to the animals to optimize growth and marketability.

Antibiotics harm fish and aquatic life. Image: Giant Group, Georgia Aquarium, Wikimedia.

Other ways animals are affected? Aquatic life itself is changing: so much estrogen has entered rivers and ponds that male fish are showing genetic changes including the development of intersex fish, especially downstream of wastewater treatment plants: notable is Washington’s Potomac River.

Filters are one approach: water treatment plants have been successful at filtering out ibuprofen but couldn’t catch diclofenax, another pain reliever. Chlorine used in drinking water treatment does reduce bacteria and also degrades acetaminophen and the antibiotic sulfathiazole, and also carbamazepine (by 75%). Still, chemicals are getting into our bodies simply by turning on the tap: Southern Nevada Water Authority found antibiotics, antipsychotics, beta blockers, and tranquilizers in the drinking water as far back as 2010. It is only getting worse.

SOLUTIONS

Pharmaceutical systems include manufacturing, distribution, consumption, disposal, and waste treatment: each step of the process offers opportunities for intervention and innovation. Regulations, at a national, local, or global level, can be effective: compliance is now an industry with consultants like Stericycle with programs “designed to meet regulatory requirements.” Of course, pharmaceutical businesses have in-house programs and systems, including segregating hazardous waste pharmaceuticals that are then sent to a Treatment, Storage, and Disposal Facility (TSDF). It’s a big business: UBS and Vanguard are investors, along with 500 other financial funds. Stericycle has 22,000 employees: competitors include Republic Services with 36,000 and Waste Management with 42,000 employees. It’s a business of the future: pharmaceutical use shows no sign of decreasing, although there is a movement to encourage safer drugs.

Jardine Water Purification Plant, Chicago, Illinois, USA. Image: wikimedia.

Nations and cities can take action. Water facilities such as the Jardine Water Purification Plant in Chicago, Illinois, world’s largest by volume, draws water from the American Great Lakes for distribution to 390 million urban residents. Research and innovation here could lead the way. In Europe, Germany invested one billion euro in the last two decades to water infrastructure including wastewater collection and treatment, in some ways advancing beyond the EU’s Council Directive 98/83/EC.1

Waterways themselves can innovate. When the Roman Aqueducts were built, it was due to an increasingly polluted Tiber River. When London’s water supply from the Thames became problematic, a public-private system was developed: the New River. Will the Grand Canal of China, part of the Belt and Road Initiative, lead research and action to improve the aquatic environment ? Might Inland Waterways International champion ways to improve the health of rivers and other created waterways?

SOLUTION: YOU – What can you do?

Don’t purchase bulk or volume packaging, avoiding accumulation of unused or expired chemical formulations.

Never flush unused medications, vitamins, or supplements down the drain.

When you must dispose, trash/landfill is preferable to flush/water. First, remove pills from container (recycle container),  then crush the pills, add a bit of water, and seal the result in a strong plastic bag before placing in trash.

TRANSPORT: Channel Tunnel Celebrates 25 Years

“Chris Froome: First person to cycle through Eurotunnel.” In the Chunnel’s third ‘service’ tunnel. Image: wikimedia.

Frank P. Davidson, American co-founder, in 1957, of the Channel Tunnel Study Group, coined the word “chunnel” for the fixed link between France and England that had been a dream of Napoleon, and drawn up as an engineering plan by Albert Mathieu-Flavier in 1802. Many historians credit Davidson whose Study Group worked with Charles Dunn of International Engineering Company/Morrison-Knudsen. Bechtel Corporation, Brown & Root, and banker Thomas Lamont, to design the three-tunnel system, as the “father of the Channel Tunnel.”

“Folkestone White Horse” carved by artist Charlie Newington as a Millennial Landmark on the cliffs overlooking the English Terminus of the Channel Tunnel.

Built by 13,000 workers from France and England, the tunnel opened 6 May 1994 and was immediately named one of the Seven Wonders of the Modern World. It’s an economic, and environmental, success. The Channel Tunnel has proved valuable to participating economies (2018 figures):

Total passengers: 20,611,337

Total cars: 2,610,242

Total freight trains: 1,797

Total trucks: 1,641,638

Total trade through the Channel Tunnel: Euro 137.8bn

Source: Ernst & Young 2018

ENVIRONMENT: Economic contribution is matched, perhaps exceeded, by environmental value: the tunnel helps to collect and mitigate emissions, making the Eurostar trip from London to Paris 90% cleaner than a short-haul air flight.

ANNIVERSARY GIFT: For its 20th anniversary, in 2014, Eurotunnel added another Channel to the Chunnel (the neologism was coined by Davidson): mobile telephone and internet came to the Channel Tunnel. What should the Channel Tunnel do for its 25th anniversary. One possibility: enhancing the power of connectivity, seeing borders as opportunities, not barriers.

CITIES: Capitals Built in Earthquake Zones

“Kathmandu: A collage,” 2012. Image: wikimedia.

Are capitals “moveable feasts?” Yes. History is filled with examples of capitals moved for new dynasties, new visions, coastal security, and more central political representation. In the future, we may see more relocations of capitals. Here’s three reasons:

EARTHQUAKES AND CAPITAL CITIES: There are other capitals, built on seismic ground, like Kathmandu or Tokyo, that may need to move. Another option, illustrated by Tokyo, might be to build a “spare battery” capital away from shaky ground. Indonesia is also earth-quake prone, located in the volcanic Ring of Fire; choice of a new capital location may require seismic assessment before a site is chosen.

What world capitals are vulnerable to shaky ground? At the time it was built, no one knew that Mexico City was located on ground susceptible to earthquakes. With a population of 20 million, the city is dense. Skyscraper towers can become “unintended object of mass destruction,” according to Michael Floyd of MIT’s Department of Earth, Atmospheric and Planetary Sciences. Loss of a command-and-control center that is a capital city can inhibit and delay disaster response, as seen when on 12 January 2010, Port-au-Prince, Haiti suffered the loss of records, legal documents, land, census data, tax records, and tragic loss of life, during an earthquake that damaged the government building.

RISING SEAS AND COASTAL CAPITALS: Rio de Janeiro, Brazil and Lagos, Nigeria are former capitals that ceded succession to Brasilia and Abuja. Both Rio and Lagos are ports. Many great capital cities were built as ports, among them Jakarta. Now, Indonesia may move its capital. Rising seas will inundate many capitals that also serve as ports.

NEW CAPITAL, NEW VISION: Moving a capital can mean a shift in demographic clout, inviting political power to more central areas of a nation. Jakarta is considering an area of Borneo. Will Mexico City plan a new Distrito Federal perhaps  also serving as a regional capital for the Americas?

NEXT STEPS FOR CAPITALS IN EARTHQUAKE ZONES: The massive urban centers that are capitals, even if the government center moves, will still remain vulnerable. Earthquakes will continue: what can be done to preserve and protect cities built on shaky ground?

CAPITAL CITIES IN EARTHQUAKE ZONES

Mexico City, Mexico

SPACE: Photo of Infinity?

Enter here: matter, time, and space. Black hole Messier 87,  galaxy located in Virgo cluster 53 million light years away. “Black Hole” photograph by Event Horizon Telescope Collaboration, 10 April 2019. Image: wikimedia commons.

April 2019. A photo of a black hole just gave the world first view of what was thought unseeable. Black holes are so termed because matter, time, space, even light, are pulled into the vortex and never come back, or perhaps become suspended in the energy field around the black hole called the Event Horizon, identified by Stephen Hawking and suggested by Einstein. Messier 87, a very large black hole photographed today, is termed “a supermassive spacetime deforming structure.” (Heater, 2019).

Event Horizon Telescope Collaboration worked as a team of eight telescopes around the world, including coordination by NASA. One of the project heroes: Katie Bouman, postdoc fellow from MIT’s Computer Science and Artificial Intelligence Laboratory (Bouman will teach at Caltech in the fall of 2019), who worked on the CHIRP (Continuous High-resolution Image Reconstruction using Patch priors) algorithm that combined the eight data flows into one image. Also on the CHIRP team: MIT’s Haystack Observatory and Harvard-Smithsonian Center for Astrophysics. Event Horizon’s photo may place Bouman in the tradition of Photo 51. It’s worth noting that Event Horizon’s historic photo is evidence of the essential importance of global collaboration in space; is this hope for a path to peace?
