Right now we notify the story of Mária Telkes, one of the builders of solar-thermal storage devices. Telkes was so focused to the environment of solar energy that while she was operating at the Massachusetts Institute of Technologies, she earned the nickname the “Sun Queen.” About her life span, she registered much more than 20 patents, approximately all connected to harnessing the ability of the solar.

Her innovations that utilized solar vitality incorporated an oven, a desalination machine and a person of the first photo voltaic-heated homes, the Dover Sunlight House, constructed in 1948. We read about Mária Telkes from Erin Twamley, a children’s e book creator who shares the stories, occupations and the superpowers of each day gals. She stated she would really like to see Telkes in each individual fifth grade classroom to encourage young people.

EPISODE TRANSCRIPT

Johanna Mayer: In 1948, a odd house appeared in Dover, Massachusetts. 

Currently, Dover is a properly-to-do suburb of Boston, but it employed to be rural farm nation. Narrow roads, yawning green lawns, fields with horses. The residences tended to be stately Colonials, or it’s possible the newer ranch design. 

So when this new house went up… it trapped out. Big time.  

Some say the property resembled a wedge of cheese. Imagine obtaining a triangular wedge of cheddar and placing it on the table with the large aspect experiencing down. That’s the condition of this residence. The slanted component of the cheese wedge – the back of the home – seemed quite regular, with brown siding and some home windows. But the other facet of the wedge – in which the rind would be – was a futuristic house residence. It was lined edge to edge with eighteen 10-foot-tall, imposing glass windows… designed to beckon in the solar.

I’m Johanna Mayer, and this is From Our Inbox, a collection from Shed Women of Science. This abnormal house was referred to as the Dover Solar Residence. And it was the brainchild of Hungarian-American biophysicist Mária Telkes.

Erin Twamley: &hairspMy title is Erin Twamley. I am a children’s e book writer who loves to share the stories, careers, and superpowers of day-to-day women. 

Johanna Mayer: Erin writes books about what she phone calls “everyday superheroes” – women who work in STEM, or science, technological innovation, engineering, and math. It was Erin who initially wrote to us about Mária Telkes. 

Erin Twamley: I would appreciate Dr. Maria to be in just about every fifth grade classroom. Dr. Maria truly helped to condition some of our knowing of what we can do with solar power.

Johanna Mayer: Mária Telkes was born in Hungary in 1900, and got interested in photo voltaic electricity whilst studying at the University of Budapest. By 1924, she’d gotten her PhD in physical chemistry, and she made the decision to move to the US to operate as a biophysicist at the renowned Cleveland Clinic. Biophysicists normally apply the principles of physics and math to organic systems – for example, when she was at the Cleveland Clinic, Mária worked on a photoelectric device that recorded brain waves.  

Immediately after a couple a long time, she moved to MIT. And she grew to become so devoted to the world of solar, that she before long attained a nickname: the Sunshine Queen.

Around her life time, the Sunlight Queen would get paid additional than 20 patents, practically all of which experienced to do with harnessing the energy of that terrific massive burning ball in the sky.

Erin Twamley:  I believe a single of the neatest issues that she came up with is referred to as a single of the 1st solar ovens that would be quick to use, and that could be employed in distant spots.

Michelle Addington: This a single is near and dear to my coronary heart because I designed a moveable, lightweight solar oven when I was a mechanical engineering college student.

Johanna Mayer: This is Michelle Addington – she’s the former Dean of the College of Texas at Austin University of Architecture.

Michelle Addington: We simply cannot comprehend the breathtaking amount of thermal vitality that is contained in the sun. We really don’t occur shut to comprehending it.

Johanna Mayer: Mária utilised this observation to construct an ingeniously easy photo voltaic oven. In essence, it was that insulated home with a window, shrunk down to oven measurement. Steel plates and mirrors within the box captured the photo voltaic wavelengths that came through the glass window – and the oven would heat up to 350 degrees. All through a demonstration of the oven, Mária stated, “Everything seems to style so much improved when it is cooked by the sunshine.” 

When Planet War II broke out, Mária was temporarily reassigned to the U.S. Office of Scientific Study and Advancement. And she was tasked with resolving a really serious difficulty: American soldiers, stranded in the Pacific theater, have been dying of dehydration. After once again, Mária turned to the sunshine.

Michelle Addington: You choose your saltwater. You kind of unfold it on a surface area preferably a black floor exactly where it is really going to obtain immediate sun. The drinking water will evaporate. Definitely the salt will be still left behind. So the water evaporates and it will gather on a area which is over it. Due to surface tension or friction, as the h2o vapor collects on that floor, it will commence to condense. 

Johanna Mayer: And voila – drinkable water. The navy would ultimately incorporate her photo voltaic desalination gadget in its formal conventional-problem crisis professional medical kits.

And in 1948, Dr. Mária Telkes turned her concentrate to what would perhaps be her most formidable venture nevertheless: the Dover Solar Property.That strange, cheese-formed household with a row of 18 windows, built to use photo voltaic electrical power to heat a house. 

The residence was funded by the philanthropist Amelia Peabody and with the help of the notable architect Eleanor Raymond, Mária created a household in shape for a Sun Queen.

Here’s how it worked. All those home windows? They ended up sunlight collectors. There were being two levels of glass, divided by some airspace and backed by a black sheet of steel. As the sunshine shined, the air in that house would warm up. And Mária place huge vats of Glauber salts close to that heat air. 

Michelle Addington: And so what would happen is these sort of salts started to liquefy. They had been absorbing and absorbing and absorbing and absorbing and absorbing warmth. They mainly functioned as a battery. You know, so if there was no put for them to dump the heat, you know, they would just preserve heading extra and extra liquid. 

Johanna Mayer: So how do you extract the heat air from all those salts? 

Michelle Addington: Just just type of go air in excess of that. If you passed air more than that, you started out to cool down these large containers of salts. You’d heat up the air as you were cooling down the vats of salts, as they were being providing up their warmth.

Johanna Mayer: Fans circulated that heat air throughout the home.

Michelle Addington: This permitted for stable problems it acted as a great battery, uh, and it could perform for a selection of times without having having sun on it mainly because of the amount of power that was contained in this type of substantial collection of vats. 

Johanna Mayer: For two many years, the house functioned rather a great deal as prepared. A relatives moved in, and took up residence in the cheese-shaped Sunshine Household, offering tours to reporters and curious rubberneckers alike. It was the only dwelling in the environment heated completely by solar power. But during the third New England winter season, chilly hard reality established in. 

Michelle Addington: Two issues: The salts on their own are really alkaline and therefore specified to corrosion. And corrosion is in fact what sunk the undertaking. 

Johanna Mayer: Ultimately, mainly because of the unlimited melting and cooling and recrystallizing of the Glauber salts, the substance wasn’t being combined adequately. 

And the other challenge? Effectively, it is a single that it’s possible was not top rated of brain for Mária back again in the ‘40s, but is crucial for us to feel about these days.

Michelle Addington: The largest problem is the truth that cooling is a single of our our greatest requires. So much of the target, of the whole passive solar motion, a great deal of organic programs for properties was crafted on the assumption that we essential warmth. That is not the entire world that we are in. It really is quick to heat. It is genuinely tough, usually takes considerably more electricity to interesting, a few instances extra power to shift a BTU of heat out of a developing than it is to set a BTU of heat into a developing. 

Johanna Mayer: By 1954, the Solar House’s photo voltaic heating program officially went dim. But Mária Telkes was not discouraged. The Sunshine Queen understood that no single house could respond to the world’s photo voltaic power difficulties.            

She once stated: “The challenge of the sunshine-heated residence are not able to be solved by one particular or two experimental houses. But each individual new residence is a different experimental stepping stone towards the use of the sunlight as a gasoline useful resource.”

Dr. Mária Telkes died in 1995, at age 94. But her legacy lives on. Right now, the variety of people setting up solar panels in their properties is constantly rising – and in a current Pew review, 39% of homeowners surveyed stated they were being critically thinking of likely photo voltaic.

And to these individuals continue to considering… I’ll depart you with the Solar Queen’s own text, from 1951: She wrote:  “Sunlight will be used as a supply of strength sooner or later anyway. Why hold out?”
