Google has replaced their homepage logo with an animated Doodle in honor of prolific solar energy scientist Mária Telkes, nicknamed “The Sun Queen.”
Mária Telkes was born in Budapest, Hungary on December 12, 1900, and she received a thorough education in the sciences, including a PhD from the University of Budapest in 1924. Later that year, Telkes visited a relative in the United States and decided to immigrate there soon after.
In the early years of Mária Telkes’ career, she researched biophysics and particularly the energy created by living things. Before long, her interests shifted toward finding ways to convert heat into energy, and ultimately, in 1939, joined the newly formed MIT research group focused on solar energy.
Amidst World War II, the U.S. government’s Office of Scientific Research and Development hired Mária Telkes’ for her expertise in solar energy and innovative ideas for the blossoming technology. One of her most famous inventions was developed during this period, a solar-powered distiller which is able to clean water for use in medical procedures or make seawater drinkable for soldiers lost at sea.
Continuing her work with MIT, Telkes participated in a project to use solar energy to keep a house warm during the bitterly cold winter in Massachusetts. Her initial experiment with solar powered heating ended in failure, and it led to Mária Telkes being removed from MIT’s solar energy team. However, she did not let this setback end her career or stop her from solving this particular problem.
In 1948, in conjunction with architect Eleanor Raymond and with funding from philanthropist Amelia Peabody, Mária Telkes designed a system that channeled the heat of sunlight into a special material between the walls, Glauber’s salt, that absorbed the energy. As the salt cooled, it would release the stored energy as heat, keeping the house (referred to as the Dover Sun House) warm.
After Telkes was let go by MIT in 1953, she continued her solar energy research at New York University College of Engineering. There, she was given a grant from the Ford Foundation to create an oven that works on solar energy. The intention was to create something that could reach 350°F and be usable by those who do not have the traditional needs of an oven available to them.
The resulting solar oven was extremely effective, and was even safe enough for children to learn to cook with it. Telkes even adapted the solar oven design to be used by farmers to dry their crops. Given the oven’s affordability and ease of use in remote locations, Telkes’ solar oven design is still in use to this day.
All of these innovations (and many more) in solar energy earned Mária Telkes the nickname “The Sun Queen.” As for why Google chose today to honor the acclaimed scientist, on December 12, 1952 — 70 years ago today — Mária Telkes was chosen as the first ever recipient of the Society of Women Engineers Achievement Award. Additionally, today would have been Telkes’ 122nd birthday.
The animated Google Doodle being showcased today prominently features some of Mária Telkes’ inventions like the solar distiller, solar oven, and the Dover Sun House. The Doodle artwork shifts between the warm colors of daytime and the cool shades of the evening, representing the collection of solar energy during the day to be used through the cold nights.

Tesla and Rivian have been embroiled in a lawsuit in which the former accused the latter of having stolen battery technology by poaching Tesla employees.
It sounds like the two automakers are finally about to settle the lawsuit, which has been going on for 4 years.
When Tesla filed the lawsuit, it wasn’t clear what trade secrets Tesla was claiming Rivian had stolen. However, we noted that the employees listed in the lawsuits were two recruiters, an EHS manager, and a manager of Tesla’s charging networks.
The automaker claimed that these employees brought “documents consisting of highly sensitive trade secret, confidential, and proprietary engineering information” when they went to work for Rivian.
Over a year later, we now learn that Tesla had notified the court that it expects to file to get the lawsuit dismissed after reaching a conditional agreement with Rivian. The company didn’t disclose the details of the settlement (via Bloomberg):
Tesla didn’t disclose specifics about the agreement in a court filing, but told a California state judge that it expects to seek dismissal of the case by Dec. 24 upon satisfactory completion of the terms.
Neither Tesla nor Rivian have commented on the reported settlement.
While Tesla has claimed that it somewhat open-sourced its patents, we have previously noted that it’s not exactly the case. Tesla claims to let other companies use its patented technology as long as they themselves don’t sue them over patent rights.
And in this specific case, Tesla alleges that Rivian has specifically hired employees to steal technologies. Again, Rivian has denied the allegation.
Electrek’s Take
The terms are unknown, but in similar cases, it often involves things like some level of access to make sure that no proprietary technology is being used or has been used.
The lawsuit is not exactly clear, but based on the timeline and the allegations of “next-gen batteries”, Tesla could have been talking about its 4680 battery cells, although those are cells. It could also be the structural battery pack.
French infrastructure specialists Proviridis have partnered with EVSE manufacturer Kempower to deliver a novel, underground charging solution for electric semi trucks designed to easily integrate into existing truck depots.
By installing its high-powered charging cabinets underground and integrating the charging cables into a solid metal pipe, Kempower and Proviridis have been able to make room for high-powered charging points in an existing truck depot that didn’t have enough space to install either conventional EVSE or overhead “drop lines.”
For the pilot, the metal pipe is painted in a striking yellow color to make it easier to see while maneuvering the lot, and keeping the dispensers themselves more protected than conventional concrete bollards. The 600 kW power cabinet is positioned a few yards away – a typical space-saving Kempower solution – and connected to the charge points by underground cable.
Proviridis believes their solution provides enough of a competitive advantage that fleet buyers looking to electrify will be eager to give it a try.
“The product is durable across a wide spectrum of temperatures and conditions, requires minimal ventilation, and can cater for a wide range of customer needs,” explains Olivier Verdu, Technical Director at Proviridis. “These are features which perfectly place the Kempower solution for this type of charging configuration in a logistics environment.”
