The Einstein Refrigerator: Built to Last 100 Years

Jul 24, 2012

by Karen Brown handmade and vintage goods

The unknown whiz-kid who whips up the next great invention in a garage is part of our modern mythology. But what happens when one of the greatest minds in theoretical physics takes on a completely mundane task, reinventing a common household appliance?

In 1926, five years after winning the Nobel Prize in Physics, Albert Einstein read a news story about the death of a Berlin family, killed by toxic fumes that leaked from a broken seal in their refrigerator. Dangerous leaks like this were becoming an alarmingly frequent occurrence as old-fashioned ice boxes were replaced with modern refrigerators that used poisonous coolants.

Einstein became preoccupied with this tragedy, insisting that a better refrigerator design must be possible. He and former student Leó Szilárd – a gifted young physicist who went on to conceive the nuclear chain reaction and electron microscope – set out to find one.

Their approach to the problem sidestepped all conventional thinking about refrigeration. Because refrigerator leaks are usually caused when bearings and seals wear out, the team believed they could prevent this danger by designing a device with no moving parts: no motor, no mechanical motion, nothing to wear out. They used their knowledge of thermodynamics to produce an absorption refrigerator, a device that drove a combination of safer gases and liquids through three interconnected circuits. It required only a small pilot light as a heat source and was hermetically sealed and safe — so safe that some experts estimate the casing could last 100 years.

Patent diagram for an Einstein-Szilárd refrigerator and a physical prototype with beautiful Art Deco styling, by engineer Albert Korodi.

There were many challenges to overcome. Some of the designs were too noisy, some not as efficient as they would have liked. But Einstein’s years as a patent clerk served the team well. Together, he and Szilárd received 45 patents in six countries for refrigeration technology.

Yet none of their inventions ever reached customers. A worldwide depression, growing political instability in Europe, and the introduction of the less-toxic coolant freon discouraged Einstein and Szilárd from continuing the project. Ultimately, appliance manufacturer AB Electro Lux bought their key patents, and that was the end of the Einstein refrigerator.

Or was it? Times have changed. A refrigerator that lasts 100 years and uses less energy looks tantalizingly attractive as we try to discover ways to live with more efficient, less disposable things. And concerns are mounting about the coolant freon, now recognized as a serious environmental hazard. Could the Einstein refrigerator be poised for a comeback?

It just might be. In 2008, Time honored scientists at Oxford University – led by engineer Dr. Malcolm McCulloch – with a “best invention” award for new research based on the Einstein-Szilárd designs. McCulloch said the Oxford team was developing more robust versions that could be used in areas without electricity, and that these improvements might quadruple the appliance’s efficiency. They’ve also looked into providing the necessary heat source through a small solar thermo device. “No moving parts is a real benefit because it can carry on going without maintenance,” McCulloch said. Dr. McCulloch told me earlier this month that the final paper on this project was now being written and will be made available to the public.

The Einstein refrigerator is an example of a design from the past with exciting new possibilities. We have become accustomed to thinking that all important inventions lie somewhere in the future. But when it comes to solving today’s problems, it feels good to know there might be good, useful, very smart ideas just waiting to be rediscovered. Although it’s 86 years old, the Einstein refrigerator could be one example of an idea whose time has finally come.

    I was so blown away by this 20 years ago, I did my very first speech in college on this very subject. To my surprise, even over my nervousness, the class was quite intrigued. This took me in a technical direction as I run a Chicago Technology Services Provider in Chicago. Great picture and article, there is always a reason to come back to the blog.

    What brilliant minds and how exciting that an idea's time can come, even decades later. Anything that is more environmentally safe and sound has to be good - I'm glad there are such bright sparks out there continuing to look at things and revisit old ideas with open minds. Thanks for the wonderful article, Karen.

    Where I live, people are also looking to other ways of preserving food, bringing back old recipes for canning, pickling, fermenting, and putting up all kinds of preserves. A farmer in the area has slowly developed his own hard shell squash. He calls it "Earthquake" because it can protect the squash for a year if we lose power for a long time due to an earthquake!

    We are being programmed to believe the His-story that is given to us by the conquers. There is evidence All over the world of past civilizations that were much more advanced than us. Tesla was inspired by the great Pyrimid in Egypt, 2000 yrs old batteries were discovered in the Middle-east, The Dogon Tribe of Africa have symbols for what we are discovering today about Atoms with Quantum Physics. The Mayans built temples that relate to temples built thousands of years earlier in Egypt. What was going on ? There is a better way! as long as people can profit from selling "stolen" "fossil fuels" or selling "Genetically Modified Organisms" (GMO's) we may never know. We must stand up for the Earth to protect what is ours or we will end up like Mars! Blessings to All .

How exciting to dig through his past inventions and pull up schematics that follow a "less is more" approach that works for our environment today. Now if we could thank him by letting him see this infamous"God Particle" we've created. That would really blow his socks off.

    What an enjoyable piece! I'll be delighted to learn if Einstein's innovations in this area are eventually used to build a more eco friendly refrigerator. When you imagine how many are purchased every year around the world and that that number is likely growing it's exciting to imagine the impact of these improvements on the environment!

  • TheMillineryShop

    Marcia Lacher from TheMillineryShop said 8 years ago

    We live in such a throw-away world where almost everything has its own built-in obsolescence. Many young kids are on their 5th or 6th cellphones and it isn't just the wealthy ones either. We must teach our kids to seek out quality, and to cherish and value their possessions. Even I have a whole slew of hairbrushes, most of which I don't use. My grandmother had just the one, and she used it for over 60 years.

  • blainedesign

    Karen Brown from blainedesign said 8 years ago

    Einstein said, "Make everything as simple as possible, but not simpler." To me, the refrigerator is such a great example of that thinking -- the smallest energy source, the greatest economy in design, the sleekest possible approach with no moving parts.

  • PopLoveCouture

    Shai Wallach from PopLoveCouture said 8 years ago

    I for one, am one of those people who hear Einstein's famous quote - "Everything should be made as simple as possible - but not simpler" - and completely does the opposite. It really does take a genius to take an already great invention and improve it, simplify it, make it more efficient.

    great post! I live off grid on solar, and for us getting a fridge that wasn't powered by propane (yuck), but that could be powered by the array even in winter and at night, was a huge deal. Our fridge is called a Sunfrost, it is made in Arcata California. They are, as I understand it, the most efficient fridge in the world, costing about 3.00 a year to run. An even better, more efficient fridge would be amazing!

  • OpulentOddities

    jordan stultz from OpulentOddities said 8 years ago

    i think things now a days are made with intent of breaking. so quick to throw out the old and consume consume consume. however, because of our consuming nature, things are not as meaningful (rather acquiring things becomes an obsession). we do not take care of what we have, making things that essentially disposable, excuse me, "obsolete," even more prone to damage. we think this is a flaw in design, but really, we allow and support this rapid, obsessive consumerism buy continuing to purchase faulty products. its a cycle, and its horrible. people post WWII (boom in mass production) or even pre industrial revolution, had less things. and also, these things last longer because they were meaningful. no one cares about that 3.99 hair bow you bought from urban outfitters. there are THOUSANDS like that being produced. you lose it, no big deal! go buy another. (it was bound to fall apart anyway, right?) i guess which is why handmade or artisan goods and salvaged vintage/antique goods are SO important. creating or saving something special. yes it is consuming, but you are not supporting the machine of consumption in this "buy or die" or "buy until you die" society. these goods, with care, can last your life time. there is meaning infused to them (ones you have assumed into the piece, intended meaning by the artist). you have a connection to the piece for one reason or the other, the item is special, and you will take good care of it. i have handmade items i've bought six years ago when i first joined etsy or from local markets. i still have them, even if they aren't on display. they are not in view, but i still keep them--and protect them, in water tight boxes. nothing you buy from the retail giants can compare. mass produced items are like grocery goods--toilet paper, food, or detergent, in our society-- good for their use, but essentially, get thrown away, eaten, or used up and are "obsolete." ending mass production is a ludicrous idea. obviously we need toilet paper, pens, soap, medications and things like that. if they were handmade, no one could afford basic self-maintenance among many other things. ending mass production is not the answer. supporting local artists, farmers, businesses, musicians, restauranteurs, crafters, bakers, soap makers (etc!) as well as supporting people through online venues IS the answer.

    A few years ago, we lived in a cabin with no electricity, and our "fridge" was an insulated hole in the ground with a wooden casing that had an attic-door style opening. It worked perfectly, given that we have permafrost in Yukon. This autumn, we're moving to the East Coast, which is much warmer, with a frost line 4' below the surface, so we'll be "refrigerating" our food in a water-tight box anchored in our fast-running creek, during the warm months, and during winter, in an interior insulated box with a hole to the outside, allowing just enough cold air n to keep food cold, but not frozen. Later, we'll construct a good, old-fashioned root and libations cellar. Maybe not as convenient as a refrigerator, but we found enormous relief when living without the large appliance (mostly wasted space- so inefficient- and also noisy no matter how "whisper quiet"- we have sensitive hearing). I adore Einstein, and think he would have appreciated our unusual, but effective solutions to fresh-food-storage. :)

The parts that are in them a lot of times have to be replaced in that time as well. I'm happy to see technology improve in positive ways. It is great to see more and more energy efficient items reaching our market place. p.s I'm amazed by Einstein's patience!

    Thank you Etsy for articles like this one! It makes us all aware of the wild and unpredictable creative impulse that can affect anyone at anytime. This article has brought to light an invention that could mean so much to the entire world. Such a clever device...lost in time. A brilliant invention for which there is enormous need, and yet it languishes in obscurity. But thanks to Etsy, and to it's diligent researcher and writer, it has been unearthed and brought back to the surface of human awareness. Sidelined not because the concept or execution were flawed, but, in fact, because they were not. And so we are all startled by a blinding flash of inspiration from the past. This good idea was buried exactly because it was such good idea. What a provocative article. Good work, Etsy

    In the throw away society it is nice to see an article written about something built to last. Looking to heros, and using them as an example is a very affective way to get a point across. I liked this blog due to the fact it was well written and I sympathize with the cause.

    This article is confusing to me. I am an engineer. Absorption refrigeration has been and is widely used throughout the world. It is not (and, thermodynamically, can never be) as efficient as the vapor-compression cycle used in modern refrigerators. I have removed many building-scale systems that were costing their owners a hundred thousand dollars a year in fuel over a modern system. While a small absorption system *must* be sealed for it to work and hence would be a great solution to Einstein's seal problem, we no longer use refrigerants that are toxic to the point of being a risk. The longevity/integrity of the system would be a big improvement over modern consumer electronics, but having a high-grade heat source (even if small, a pilot light is a) gas/oil and b) hotter than you want to try and achieve with electricity if you care about your bills) is a problem. Einstein was a brilliant and deeply empathetic man, but without understanding what these recent developments are, I struggle to accept the points in the article when so much appears to be glossed over in the interests of a 'guess what' theme.

    Hi Kidsturk, Of course, it's not possible to go into great depth in a short Etsy post. If you would like to know more about this project, I suggest you get in touch Dr. Malcolm McCulloch at Oxford – he's mentioned in the post – to find out more.
