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.

Looking to Downsize? You Can Buy a 5-Room DIY Cabin on Amazon for Less Than $33,000

If you’ve already mastered DIY houses for birds and dogs, maybe it’s time you built one for yourself.

As Simplemost reports, there are a number of house kits that you can order on Amazon, and the Allwood Avalon Cabin Kit is one of the quaintest—and, at $32,990, most affordable—options. The 540-square-foot structure has enough space for a kitchen, a bathroom, a bedroom, and a sitting room—and there’s an additional 218-square-foot loft with the potential to be the coziest reading nook of all time.

You can opt for three larger rooms if you're willing to skip the kitchen and bathroom.Allwood/Amazon

The construction process might not be a great idea for someone who’s never picked up a hammer, but you don’t need an architectural degree to tackle it. Step-by-step instructions and all materials are included, so it’s a little like a high-level IKEA project. According to the Amazon listing, it takes two adults about a week to complete. Since the Nordic wood walls are reinforced with steel rods, the house can withstand winds up to 120 mph, and you can pay an extra $1000 to upgrade from double-glass windows and doors to triple-glass for added fortification.

Sadly, the cool ceiling lamp is not included.Allwood/Amazon

Though everything you need for the shell of the house comes in the kit, you will need to purchase whatever goes inside it: toilet, shower, sink, stove, insulation, and all other furnishings. You can also customize the blueprint to fit your own plans for the space; maybe, for example, you’re going to use the house as a small event venue, and you’d rather have two or three large, airy rooms and no kitchen or bedroom.

Florence’s Plague-Era Wine Windows Are Back in Business

Many bars and restaurants have started selling takeout cocktails and other alcoholic beverages to stay in business—and keep customers safe—during the coronavirus pandemic. Meanwhile, 17th-century Florentines are surely applauding from their front-row seats in the afterlife.

As Insider reports, a number of buildings in Florence had been constructed with small “wine windows,” or buchette del vino, through which vendors sold wine directly to less affluent customers. When the city suffered an outbreak of plague in the 1630s, business owners recognized the value of these windows as a way to serve people without spreading germs. They even exchanged money on a metal tray that was sanitized with vinegar.

Things eventually went back to normal, and the windows slowly fell out of fashion altogether as commerce laws evolved. This year, however, they’ve made a comeback. According to Food & Wine, there are currently at least four in operation around Florence. Osteria delle Brache in Piazza Peruzzi is using its window to deliver wine and cocktails, for example, and the Vivoli ice cream shop, a go-to dessert spot since 1929, is handing out sweet scoops and coffee through its formerly dormant aperture.

Apart from the recent resurgence of interest, the wine windows often go unnoticed by tourists drawn to the grandeur of attractions like the Uffizi Gallery and the Florence Cathedral. So in 2015, locals Matteo Faglia, Diletta Corsini, and Mary Christine Forrest established the Wine Window Association to generate some buzz. In addition to researching the history of the windows, they also keep a running list of all the ones they know of. Florence has roughly 150, and there are another 100 or so in other parts of Tuscany.

They’re hoping to affix a plaque near each window to promote their stories and discourage people from defacing them. And if you want to support their work, you can even become a member of the organization for €25 (about $29).
