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.

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.”

With up to 500 km (310 miles) of all-electric range, the new Mercedes eActros 600 electric semi truck was designed for long-haul trucking – and now, it’s officially in production at the company’s Wörth plant in Bavaria.
“The start of series production of our eActros 600 is a further proof of our ambition to transform the industry,” offers Karin Rådström, CEO of Daimler Truck. “With a range of 500 kilometers on a single battery charge, our eActros 600 is addressing the long-haul segment in Europe which is responsible for two-thirds of CO2 emissions from heavy road freight. Our battery-electric long-haul truck will therefore make a real difference.”
In addition to the 600’s additional range, the newest eActros marks another milestone by becoming the first electric Mercedes semi to be manufactured on a single line (the eActros 300/400 and eEconic leave their standard production lines to have their electric drive components installed at Mercedes’ Future Truck Center in Wörth).
“With the start of series production of the eActros 600, we are expanding our Wörth product portfolio with an important vehicle for the future,” says Andreas Bachhofer, Head of the Wörth site and Production at Mercedes-Benz Trucks. “Construction of this first battery-electric truck made in Wörth will be fully integrated into the existing assembly hall, flexibly alongside the manufacturing of combustion-engine trucks. This means that we are ideally positioned for the production of larger quantities. Our production team is well prepared for the successive ramp-up over the coming months.”
The new electric semi truck features a 600+ kWh battery (hence, eActros 600) that sends power to a new, highly efficient electric drive axle developed in-house by Mercedes-Benz, good enough to “be able to travel significantly more than 1,000 kilometers per day. This is made possible by intermediate charging during the legally prescribed driver breaks – even without megawatt-charging.”
