Einstein's Design for a Fridge to Last 100 Years

After establishing the theory of relativity as a founding principle of modern physics, Albert Einstein turned his thoughts to higher matters: home appliances. In 1926, the Nobel Prize-winning scientist put his considerable mental energies towards developing the refrigerator to end all refrigerators—energy-efficient, environmentally friendly, and durable enough to last a century.

Einstein’s interest in consumer goods was initially piqued by a news story recounting the death of a family in Berlin from the poisonous fumes of their poorly sealed refrigerator—a danger which was growing increasingly prevalent as households exchanged their ice boxes for modern refrigerators containing volatile chemical coolants. He proposed a solution that avoided the use of deadly methyl chloride, ammonia, or sulfur dioxide, enlisting the aid and expertise of young Hungarian physicist, friend, and thermodynamics specialist Léo Szilàrd to draft a prototype of a safer, better “absorption refrigerator” instead.

In the traditional style of refrigerator, a mechanical compressor pressurizes potentially toxic gases to initiate the cooling process. So long as the fridge remains safely sealed, the risks to users are minimal, but a refrigerator’s moving parts often wear out its seal and expose its fatal contents to the air. Einstein and Szilàrd’s design would require no moving parts, instead using a heat source to naturally pressurize the gas contained within the series of circuits. With no immediate source of wear and tear, the Einstein-Szilàrd refrigerator would last as long as its external casing did—up to 100 years, experts estimate.

Over the course of their partnership, the two scientists took out 45 patents for refrigeration technology in six countries, eventually selling their key patents to appliance manufacturer AB Electro Lux. However, their design remained less efficient than compressor-type models, and the combined advent of the Great Depression’s effect on industrial budgets and the introduction of chlorofluorocarbons as less toxic chemical alternatives put an end to Einstein and Szilàrd’s domestic technology dreams—until a recent resurgence of interest by researchers at Oxford University, who have picked up on the idea of a fridge that can function without electricity or greenhouse gases as a green solution to our increased global dependence on cooling technologies. Though the remake of the original Einstein fridge has yet to make it to market, every kitchen might soon be keeping their drinks cold and their pie crusts chilled in Einstein’s new and improved brainchild.

You Can Now Rent the Montgomery, Alabama Home of Zelda and F. Scott Fitzgerald Through Airbnb

The former apartment of Zelda and F. Scott Fitzgerald, perhaps the most famous couple of the Jazz Age, is now available to rent on a nightly basis through Airbnb, The Chicago Tribune reports. While visitors are discouraged from throwing parties in the spirit of Jay Gatsby, they are invited to write, drink, and live there as the authors did.

The early 20th-century house in Montgomery, Alabama was home to the pair from 1931 to 1932. It's where Zelda worked on her only novel Save Me the Waltz and F. Scott Fitzgerald wrote part of Tender Is the Night. The building was also the last home they shared with their daughter Scottie before she moved to boarding school.

In the 1980s, the house was rescued from a planned demolition and turned into a nonprofit. Today, the site is a museum and a spot on the Southern Literary Trail. While the first floor of the Fitzgerald museum, which features first-edition books, letters, original paintings, and other artifacts related to the couple, isn't available to rent, the two-bedroom apartment above it goes for $150 a night. Guests staying there will find a record player and a collection of jazz albums, pillows embroidered with Zelda Fitzgerald quotes, and a balcony with views of the property's magnolia tree. Of the four surviving homes Zelda and F. Scott lived in while traveling the world, this is the only one that's accessible to the public.

Though the Fitzgerald home is the only site on the Southern Literary Trail available to rent through Airbnb, it's just one of the trail's many historic homes. The former residences of Flannery O'Connor, Caroline Miller, and Lillian Smith are all open to the public as museums.

History
The Concept of the American 'Backyard' is Newer Than You Think

Backyards are as American as apple pie and baseball. If you live in a suburban or rural area, chances are good that you have a lawn, and maybe a pool, some patio furniture, and a grill to boot.

This wasn’t always the case, though. As Smithsonian Insider reports, it wasn’t until the 1950s that Americans began to consider the backyard an extension of the home, as well as a space for recreation and relaxation. After World War II, Americans started leaving the big cities and moving to suburban homes that came equipped with private backyards. Then, after the 40-hour work week was implemented and wages started to increase, families started spending more money on patios, pools, and well-kept lawns, which became a “symbol of prosperity” in the 1950s, according to a new Smithsonian Institution exhibit.

Entitled "Patios, Pools, & the Invention of the American Back Yard," the exhibition includes photographs, advertisements, and articles about backyards from the 1950s and 1960s. The traveling display is currently on view at the Temple Railroad & Heritage Museum in Temple, Texas, and from there it will head to Hartford, Connecticut, in December.

Prior to the 1950s, outdoor yards were primarily workspaces, MLive.com reports. Some families may have had a vegetable garden, but most yards were used to store tools, livestock, and other basic necessities.

The rise of the backyard was largely fueled by materials that were already on hand, but hadn’t been accessible to the average American during World War II. As Smithsonian Insider notes, companies that had manufactured aluminum and concrete for wartime efforts later switched to swimming pools, patio furniture, and even grilling utensils.

At the same time, DIY projects started to come into fashion. According to an exhibit caption of a Popular Mechanics article from the 1950s, “‘Doing-it-yourself’ was advertised as an enjoyable and affordable way for families to individualize their suburban homes.” The magazine wrote at the time that “patios, eating areas, places for play and relaxation are transforming back yards throughout the nation.”

The American backyard continues to grow to this day. As Bloomberg notes, data shows that the average backyard grew three years in a row, from 2015 to 2017. The average home last year had 7048 square feet of outdoor space—plenty of room for a sizable Memorial Day cookout.
