SPACE: Big Ticket to Ride

Ride with Bezos? Price still unknown – the only ticket was auctioned for $28 million: for a ten minute ride, Blue Origin’s meter runs fast as a rocket. Fly with Branson? Over 600 seats on Virgin Galactic are pre-sold, going for $200, 000 to $500, 000 for a hour’s excursion. Prefer a longer stay? A space vacay to the International Space Station by Elon Musk and SpaceX: $55 million. There are other costs – environmental.

One way to evaluate financial, and environmental, costs of private space travel could be to look back to 17 December 1903 when the Wright Flyer took off from Kitty Hawk. In December 1944, the Convention on International Civil Aviation  established rules for civil aviation: stated goals were safety and international cooperation. In 2004, the world had 900 airlines, tallying 22,000 aircraft serving 1,670 airports. (Spaceports, overseen by the Federal Aviation Administration, are now in high construction demand.) In 1960, civil aviation flew 100 million people; by 2017, 4 billion passengers.  In 2019, revenues in the global aviation industry reached $838 billion. However, passenger air travel spikes the highest (and fastest) growth in individual emissions. Flight shaming (flygskam) is a resulting development. Branson and Bezos both drew criticism for spending funds on space tourism when there is a world in need below.

Commercialization of space might also be examined through the development and expansion of satellites. COMSAT, the first commercial satellite operator, began with Intelsat and Inmarsat. When “Early Bird” launched in 1965, the Communications Satellite Act had just established a policy for a commercial communications satellite system open to many nations cooperatively. Comsat began with a $5 million line of credit. Sales by 1996 were $1 billion. Launching satellites produces carbon pollution, and also another kind of pollution: traffic. As of 1 August 2020, there were 2,787 satellites orbiting Earth – 1,364 of them communications satellites both government and commercial.

What can we do to reduce space emissions pollution? Image: “Space Shuttle launched with two solid-fuel boosters (SRB.” NASA, 1981, public domain.

Branson’s Virgin Atlantic, a commercial airline, ferries passengers worldwide, diluting the energy burden per seat. But Virgin Galactic carries just six, tallying a much higher per-person emissions cost; the one-hour flight is equivalent to driving a typical car around the Earth. One concern is the type of fuel used by Virgin Galactic: the system runs on a kind of synthetic fuel that burns with nitrous oxide, shooting black carbon into the stratosphere. Blue Origin uses liquid hydrogen and liquid oxygen, causing 750 times less climate-forcing magnitude than Virgin’s (Ahmed 2021). SpaceX will bring four passengers to space in September, causing the equivalent of 395 transatlantic flights worth of emissions.

Space tourism projects market growth of 17% each year in the coming decade. Price-per-flight will be reduced, and innovations will increase. Just as SpaceX introduced reusable rockets, a game-changer for the space industry (landing 44 of 52 attempts), and Axiom is planning to launch its own commercial space station at the cost of $1.8 billion to NASA’s $150 billion for the International Space Station, privatization of space will streamline the industry. But because rockets emit 100 times more CO2 per passenger than flights (Marais 2021), and because rocket exhaust is released directly into the atmosphere from a higher point of entry, the ozone layer (earlier protected by the 1987 Montreal Protocol) may be again under threat.

Some feel private space commercialization may be a misuse of resources more urgently needed on Earth; others predict important innovations will follow July 2021’s first commercial space tourism flights. Some of the most important developments must be in fuel options and emissions management. Will commercial space flight learn from civil aviation? Bezos’ Blue Origin space tourists brought little carry-on luggage, but two significant items hitched a ride: Amelia Earhart‘s goggles, and a piece of canvas from the Wright Flyer.

This SPACE for Sale or Rent

“Atmosphere Layers, showing the Kármán Line.” What’s for sale or rent? Image: based on the work of Theodore von Kármán, vectorized by NOAA and Mysid, 2014. Public domain: wikimedia commons.

When Apollo 11 placed the first people on the moon, on 20 July 1969, NASA might have known the price per person, but seats were not for sale, or rent.

On 20 July 2021, privatization of space demonstrated an aspect of commerce: market pricing, open bidding, for sale or rent. Jeff Bezos, founder of Amazon and Blue Origin, auctioned a seat on today’s ride. When the anonymous highest bidder ($28 million) backed out, citing other commitments, the place went to next-in-line Joes Daemen, CEO of Somerset Capital Partners. Daemen in turn bounced the ball to his son, Oliver Daemen, who will become the youngest person ever to go to space.

Space tourism is having a moment. On 11 July, Richard Branson flew aloft on Virgin Galactic for a view of Earth and a glimpse of space: also aboard were three Virgin staff and two crew pilots. On 20 July, Blue Origin’s New Shepard carried Jeff Bezos, brother Mark Bezos, and two other passengers: 82-year-old Mary Wallace “Wally” Funk and 18-year-old Oliver Daemen for 10 minutes of rocket tourism.

Flying to the Kármán Line (100 kilometers: 54 nautical miles/62 miles above Earth, the point considered to be the beginning of space) is not cheap, but prices vary. What’s the cost per passenger for space tourism? Yet unknown. Bezos is funding Blue Origin, founded in 2000, with share sales of Amazon stock, selling 1.85 billion worth of shares in May 2021. Bezos donated the $28 million auction proceeds to a charitable outreach: Club for the Future. Branson filed to sell $500 million in Virgin Galactic shares after the July flight, sparking a brief halt in the stock’s trading. Virgin Galactic currently has 600 reservations for space tourism flights: pricing ranges from $200,000 to $400,000, depending upon date of purchase. To date. Blue Origin has sold seats by auction: scheduled pricing is to follow. SpaceX, founded by Elon Murk, will also carry paying passengers: three people paid $55 million each for a 10-day tour to the International Space Station.

There are some who question the ethical and environmental costs of private space. Should billionaires like Bezos, Branson, and Musk spend their money flying to space or solving problems on Earth? What about the emissions of space vehicles carrying not scientific experiments but joy-riding millionaires?

Others point out that innovation often starts with entrepreneurial investment. Early in the 20th century, in 1903, the Wright brothers flew at Kitty Hawk.  In 2003, air transport generated 13.5 million jobs and significant contributions to GDP around the world. What innovations might we see from space tourism in this century? How will Virgin Galactic, SpaceX, and Blue Origin influence development in space? Watch Blue Origin’s voyage here.

In the next post, we’ll take a closer look at the costs of private space: environmental and financial.

CITIES: Liberty, Diplomacy, Art (and Fireworks!)

“Statue of Liberty” by Tysto (Derek Jensen), 2005. Image is in the public domain, from wikimedia commons.

On Independence Day, France will give a gift of diplomacy to the United States, celebrating the shared value of liberty. France’s national motto “Liberté, Égalité, Fraternité” (Liberty, Equality, Fraternity), and the American holiday of independence, will join sentiments as a replica of the Statue of Liberty is presented by the Museum of Arts and Crafts in Paris for a ten-year visit to the land of her big sister. “Little Lady Liberty” (9.3 feet or 2.8 meters) joins the original Statue of Liberty (305 feet or 93 meters) that was a gift from France to the United States in 1886.

“The Eiffel Tower – State of the Construction.” Photograph by Louis-Emile Durandelle. public domain. Image: wikimedia.

While Frédéric-Auguste Bartholdi designed the sculpture, the creator of the eponymous Eiffel Tower in Paris, Gustave Eiffel, crafted its internal structure, introducing an innovative design that relied not on weight as support but on a flexible structure with a central pylon supporting a web of asymmetrical girders. Since its arrival in 1885, the iconic monument has stood on Liberty Island in New York Harbor, welcoming those who came to its shores in search of freedom. The visiting French replica will be displayed on Ellis Island to bear witness to Independence celebrations, before moving to other locations, culminating in Washington, D.C. for its unveiling on July 14, in honor of Bastille Day. The visitor will remain for 10 years. As the world seeks to foster shared values, should countries exchange public art for display, especially in national capitals, as an outreach of diplomacy? If you’d like to follow the journey of Little Lady Liberty, click here.

Another iconic display – both on American Independence Day and French Bastille Day? Fireworks!

ENERGY: Genie in a Bottle

“Genie in a Bottle,” from Stripped Tour, Christina Aguilera Image: wikimedia.

February 18, 2021. It’s National Battery Day. What is this genie in a bottle that we call a battery?

Lithium-ion batteries are making news. It’s a technology popularized in 1991, when rechargeable lithium-ion batteries were first used in hand-held camcorders. A decade later, Apple began using these batteries in smartphones. When electric cars entered the market (Edison worked on one, before Henry Ford invented the gasoline-driven automobile), batteries became the way to power the future. SEMATECH introduced a new industry, and now two new semiconductor materials – gallium nitride (GaN) and silicon carbide (SIC) are now being used in EV batteries. With General Motors (GM) pledging a full transition from gas and diesel to electric vehicles by 2035 (Ford, Tesla, Volkswagen and others in similar quests), the race is on.

Who’s Who (a partial list) in Electric-Vehicle Batteries:

CATL or Contemporary Amperex Technology Col, Limited, founded in 2011 in China, announced an increased investment of $4.5 billion on 4 February 2021. CATL will open a new plant in Zhaoqing, Guangdong Province, upgrade a plant in Yibin, Sichuan Province, and expand a joint venture plant with automaker China FAW Group. A new plant in Germany is also under construction. (300750:CH)

LG Chem in South Korea, world’s biggest EV battery manufacturer, just announced its battery division would now be a stand-alone business. LG counts GM, Geely Automotive Holdings Shanghai Maple Guorun Automobile Co., Hyundai Motor Group, and Tesla among its customers. Tentative name for the new business: LG Energy Solutions. (LGCLF)

Nissan Motor Co. and American Electric Power are competitors with a different strategy: reusing old EV batteries with a technology to extend lithium-ion battery life by over 30%. The experiment uses Nissan Leaf expired-batteries with a method developed by Melbourne-based Relectrify. BMW AG and Toyota are also reusing cells in EV charging. (NSANY)

Novonix is working with Dalhousie University on battery material research, noting new deals with Tesla on synthetic graphite. (NVNXF)

Panasonic. Tesla is in talks with Indonesia to build a battery cell factory with Panasonic. (PCRFY)

QuantumScape is introducing solid-state batteries lithium-metal batteries, offering a faster charge, longer life, and increased safety. The San Jose, California company filed with the SEC for a new development on 1 February 2021. (QS)

Tesla. Bringing battery production in-house has been a goal for Elon Musk who introduced a ‘tab-less’ battery called 4680 that will produce a 16% increase in range for the company’s electric vehicles. They new cells measure 46 millimeters by 80 millimeters. (TSLA)

Zinc Copper Voltaic Pile. Image: wikimedia.

The oldest battery known to history was found in Baghdad: a clay pot containing a metal tube and rod. But when Alessandro Volta discovered that zinc and coper, placed in a saline or acid solution, could transform zinc into a negative pole and copper into a positive pole, the action began. Chevrolet named one of its early EV models a “Volt.”

Will batteries advance hydroelectric power? Image: Hoover Dam, wikimedia.

Battery storage may transform hydroelectric power In Chile, a 50 megawatt-hour (MWh) battery energy storage project (think the equivalent of 5 million iPhones) will be paired with a hydroelectric facility, to store generated energy without need to construct a dam or reservoir. Will the Hoover Dam explore this technology, with consideration to drought affecting Lake Mead? It was hydroelectric power that first fascinated Nikola Tesla who, looking at a photo of Niagara Falls, said: “Someday I’ll harness that power.”

ENERGY: Renewing Hope in 2021

Winds of change are in the air. Literally.

“Vestas V90-3MW Wind Turbine of Kentish Flats Offshore Wind Fram, Thames Estuary, UK” by Phil Hollman, 2006. Wikimedia Commons.Wind Power innovator BladeBUG may aid maintenance of marine turbines, now 40% of the cost of these energy generators. If offshore wind were more affordable and reliable, it could increase its energy contribution by 18 times. BladeBug, a drone-based innovation founded by Chris Cieslak, won recognition from ORE Catapult (Offshore Renewable Energy in Blyth, UK) and will now integrate with MIMRee (Multi-Platform Inspection Maintenance and Repair in Extreme Environments). Both are part of a consortium led by Plant Integrity.

“CLT-plate with three layers of spruce” by Pañh, 2018. Wikimedia Commons.

Another renewable natural resource set to develop increased importance: wood. Can timber help to lessen the carbon impact of concrete and steel in the building industry? A form of ultra-thick plywood termed Cross-laminated Timber (CLT)  can be used for walls and floors. While the Eiffel Tower may not be redesigned, France recently ruled that all new commercial buildings must have solar or green rooftops, and has now legislated that all new public buildings be constructed with at least 50% timber. Enter a new term in architecture: “plyscraper.” Leading manufacturers that investors are watching: Stora Enso, KLH Massivholz GmbH, Binderholz, Mayr-Meinhof Holz Group, Hasslacher.

Ever since Peter G. Glaser patented solar power satellites, energy from the sun has proven efficient and relatively inexpensive as technologies for solar panels improve. But until Glaser’s innovation can be pursued, solar panels still collect only one/fifth of what is possible. Oxford PV is employing silicon with perovskite that increases solar panel efficiency by 29.52%, setting a new world record. The company originated at Oxford University, where the Oxford-AstraZeneca vaccine was developed.

Will COP26 in Glasgow, Scotland herald a new era for climate and cooperation? Image: “University of Glasgow, Scotland, 1900” Library of Congress image ppmsc.07600

Brilliant medical and scientific researchers created Covid vaccine innovations through rapid cooperative response to a world crisis that some likened to the Manhattan Project. Climate change is another world crisis. Bill Gates, co-founder of Microsoft and the Bill & Melinda Gates Foundation that has championed causes of public health, sees hope for 2021, noting the November United Nations COP26 in Glasgow, Scotland, as catalyst for nations to pledge responses to climate change. With new administrations in the United States, new political definitions of the United Kingdom and European Union, increased commitments to energy neutrality by China and others, there is reason for hope. What do you think will be the most important advances in 2021?

SPACE: Rock Hounds bring Finds to Earth

There’s a goddess on the moon and she’s a rock collector. China’s lunar explorer, Chang’e 5, named after the lunar deity, returned four pounds of rocks to Earth this week.

“The Moon Goddess Chang E.” Ming Dynasty Scroll, Metropolitan Museum of Art Acquisition number 1981.4.2. Image: Wikipedia

 

 

 

 

It’s been 44 years between rock collecting expeditions: for the first time since 1976 (Soviet Union’s Luna 24 returned 6 ounces (170 grams), humans reached the lunar surface, collected samples, and headed home with prize specimens. The USA returned moon rocks in 1972. Since making its first lunar landing in 2013, China has achieved notable milestones including the first space probe landing on the far side of the moon in 2019. Change’e 5 brought 4.4 pounds (2 kilograms) of lunar material back, landing in the Inner Mongolian Autonomous Region landing site on 16 December 2020. Some was surface rock, but a probe mechanism also collected material from 6.5 feet (2 meters) underground.

We may be in what some call a “golden age” of sampling from space. In addition to moon samples, we have retrieved interplanetary material from NASA‘s Stardust that returned samples from the tail of Comet 81P/Wild 2, and Genesis mission that sampled solar wind. JAXA’s Hayabusa that brought samples from asteroid Ryugu in December 2020; NASA’s OSIRIS-Rex visit to asteroid Bennu will return material (in 2023). Meanwhile, in 2021, we expect China’s Rianwen-1 to reach Mars, and Russia’s Lunar-24 to revisit the moon. JAXA’s Martian Moon Exploration (MMX) mission will soon return samples from Martian moon Phobos.

What did Chang’e find on the moon? The legendary goddess told a tale of global warming involving the heat of 10 suns. Perhaps rocks from the moon may shed light on Earth’s plight. As for the Chang’e mission, Pei Zhaoyu deputy director of China National Space Administration (CNSA) stated: “We hope to cooperate with other countries to build the international lunar scientific research station, which could provide a shared platform for lunar scientific exploration and technological experiments. ” Earlier, Johann-Dietrich Woerner, then director general of European Space Agency (ESA) suggested building a village on the far side of the moon to replace the aging International Space Station: “Partners from all over the world contributing to this community with robotic and astronaut missions and support communications satellites.” Frank P. Davidson, co-founder of Camp William James of the CCC, envisioned a program called Lunar U. Should there be a lunar study-abroad program for students, too?

TRANSPORT: 5G Whiz

It all started with DARPA. Image: “Darpa – Big Data.” Wikimedia.

“Gee Whiz” is an old-fashioned phrase, first used in 1876, but the combo of astonishment + speed related to the saying may well describe 5G speed in telecommunications. In this case, the G is for generation. And whiz – it’s still about speed.

5G is fifth generation mobile technology. Back in the days of 2G, mobile phones and texting were new, 3G brought mobile broadcast data, and 4G was faster and came to be called Long Term Evolution (LTE). Now we are at the advent of 5G. Ericsson created the initial 5G platform in 2017, but it is only in 2020 that 5G is coming to market. 5G is a breakthrough because of a something called “latency.”

Latency is the time it takes for information sent to be received. While 4G seemed fast at the time, taking about 30 milliseconds from sender to receiver, 5G could travel that synapse in 1-2 milliseconds. That whiz of time is barely perceptible. Closing the gap of latency will enable leaps the “Internet of Things” (IoT) including:

Autonomous vehicles

Drone navigation

Gaming

Robotics

Many breakthroughs in technology began with military or government research, including the Internet that stemmed from the Defense Advanced Research Projects Agency (DARPA), founded in 1958 by American President Eisenhower in response to Sputnik’s success the year prior. DARPA led to computer networking, the Internet, and graphical user interfaces – and also to the NASA lunar landing.

Now, government may again take the lead in connection. The United States Department of Defense is exploring sharing a new 5G wireless network with commercial enterprises. AT&T, T-Mobile, and Verizon are rolling out 5G upgrades, and Google’s Alphabet has advocated sharing the wireless spectrum. A shared network would keep military use, but add commercial partners. License bidding for spectrum access through a Federal Communications Commission (FCC) raised $4.6 billion recently; in December 2020, another auction will determine future power and access. While CTIA, trade association for the wireless industry, may favor private-sector decisions, some advocate sharing. Precedent may be found in FirstNet, AT&T’s $40 billion service for fire-fighters and public safety. In 2021, the Pentagon may direct 100 megahertz of spectrum towards the FCC for auction. What do you think of military and commercial interests – combined or separate?

Drones – both military and commercial – may benefit from 5G. Image “Drohnenflug im Abendrot.” Wikimedia

Meanwhile, 5G network leaders include Ericsson (ERIC) with a market capitalization of $25 billion, Nokia (NOK) with $18.5 billion, and Qualcomm, with $81 billion market capitalization. Ericsson created the first 5G platform in 2017. Huawei is among 35 global carriers active in 5G deployment. New chips will be needed: Qorvo (QRVO) and Skyworks Solutions (SWKS) are active. It will also mean new phones: Apple (AAPL) announced the 5G-capable iPhone 12 this week.

Speed has always driven advances in transport. Wheels were faster than walking; cars were faster than horses (we still use the term “horsepower” for speed); jets were faster than propeller-equipped aircraft. Now, a new era of connective transport is arriving, with the advent of 5G. But latency exists in more than signals; it’s also a roll-out timing factor. Full 5G capability requires new infrastructure. China, South Korea, and Switzerland made progress in 2019; in 2020, U.S. low-band is more available than mid-band or high-band, and only in some cities. By 2023, 5G may support more than 10% of the world’s mobile connections. Investors are betting on developing capacity, including chip-makers, with the next wave of significant activity from 2021-2022. Meanwhile, important policy issues regarding 5G access are in discussion: what do you think?

WATER: Rising Seas

“Sea Level Rise: 1880-2013, depicted in stripe graphic,” created by Dr. Richard Selwyn Jones, Durham University. Image: wikimedia.

CLIMATE HOT SPOTS

“2 Degrees Centigrade: Beyond The Limit,” a Washington Post series of articles won the 2020 Pulitzer for Explanatory Reporting.  The series looks at what the world will be like if we reach that temperature increase, as well as explores areas that have already exceeded 2 Degrees Centigrade. The Northeast Corridor, including Boston and New York, is one area. Another is the coastal curve south of Santa Barbara, California running through Los Angeles and into the arroyos along the Mexican border: the area has warmed at double the rate of the rest of the United States, seeing an increase of 2.3 degrees.

SEA RISE IS CERTAIN

California was also the focus of Pulitzer Prize Finalist, the Los Angeles Times, presenting articles on rising seas on the Pacific coast. The LA Times series included a climate change/oceans interactive game.

Sea rise is so gradual as to be almost invisible, but that is changing. In the last 100 years, sea rise was just 9 inches; predictions estimate it may swell to 9 feet in the next half century. Even if we meet global carbon emissions goals, global seas will rise 12 inches (NOAA 2019).

SEA RISE: REGIONAL RESPONSE  THROUGH TRADE, EDUCATION, AND INNOVATION

Rising seas are global but response is regional. California is linked to Mexico (in fact it once was Mexico, along with parts of Arizona, Colorado, Nevada, New Mexico, Utah, and Wyoming). Canada is connected, too.

Mexico, United States, and Canada already have a trade agreement, recently updated. Should the new trade agreement include a strategy for rising seas? Is there an educational mission included in the agreement? Universities and businesses along the Atlantic and Pacific coasts of all three countries should work together to design solutions. Internships and apprenticeships in businesses engaged in sea rise response could seed a new generation of experts, just as they will be needed. Regional response is scalable: the Belt and Road Initiative is another example of a connected network linked by contracts and agreements.

Happy Birthday, Internet

Internet’s 50th birthday. Image: wikimedia

October 29, 1969. Neil Armstrong had recently stepped onto another world: the moon. That same year, another new world was born. UCLA, Stanford, the University of California-Santa Barbara, and the University of Utah were working on ARPANET (Advanced Research Projects Agency Network). Graduate student Charley Kline sent a computer message from UCLA to Bill Duvall at Stanford, typing the word “Login.” The system crashed; but the letters ‘L’ and ‘O’ transmitted. Leonard Kleinrock, professor of computer science at UCLA, helped to complete the message about an hour later

Now, we’re moving into 5G. 1G was analog cellular; 2G was CDMA and GSM digital. 3G technologies like EVDO were faster; 4G LTE was even faster. 5G will deliver three changes: faster speed (moving more data); lower latency (optimizing response); ability to connect multiple devices. 5G might help autonomous vehicles become more accurate; smart roads will become more responsive, too. 5G will enable Virtual Reality (VR) and instant transmission.

The internet was born fifty years ago today.  Since then, complex transmissions have spread science around the world, and a few chats, too. But some might opine that the first two letters ever sent best expressed the wonder: “‘Lo,’ and Behold.”

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.
