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 has quietly removed the Cybertruck’s range extender from the options in its online configurator.
Does Tesla still plan to bring the product to market?
When Tesla unveiled the production version of the Cybertruck in late 2023, there were two main disappointments: the price and the range.
The tri-motor version, which was the most popular in reservation tallies, was supposed to have over 500 miles of range and start at $70,000.

Tesla now sells the tri-motor Cybertruck for $100,000 and only has a range of 320 miles.
As for the dual-motor Cybertruck, it was supposed to cost $50,000 and have over 300 miles of range. The reality is that it starts at $80,000, and it has 325 miles of range.
However, Tesla had devised a solution to bring the range closer to what it originally announced: a separate battery pack that sits in the truck’s bed. Tesla called it a “range extender.” It costs $16,000 and takes up a third of the Cybertruck’s bed.
Even though the Cybertruck has been in production for a year and a half at this point, the range extender has yet to launch.
At the time, Tesla also reduced the range that the removable battery pack adds to the Cybertruck to “445+ miles” rather than “470+ miles” for the dual motor – a ~25-mile reduction in range.
Now, Tesla has removed the option from its online Cybertruck configurator. It used to take reservations for the range extender with a “$2,000 non-refundable deposit”, as seen on the image above, but now it’s not in the configurator at all at the time of writing.
It’s unclear if Tesla is not planning to launch the product anymore or if it is just pausing reservations.
In its specs page, Tesla still lists the achievable range of both versions of the Cybertruck with and without the range extender battery:
Electrek’s Take
I’m curious. Is it dead, or does Tesla just want to stop taking reservations for it?
At first, I was curious about the product even though I didn’t think it would make up for Tesla’s significant miss on Cybertruck specs.
However, after it was confirmed that it takes up 30% of your bed and that it needs to be installed and removed by Tesla at a service center, I think it’s pretty much dead on arrival at $16,000.
It’s going to be a product limited to only a few people at best. And now that’s if it makes it to market.
With the option being removed from the configurator, there’s no production timeline available. Again, the last one was “mid-2025”, which is soon.

Tesla is losing another top talent: its long-time head of software, David Lau, has reportedly told co-workers that he is exiting the automaker.
Tesla changed how the entire auto industry looks at software.
Before Tesla, it was an afterthought; user interfaces were rudimentary, and you had to go to a dealership to get a software update on your systems.
When Tesla launched the Model S in 2012, it all changed. Your car would get better through software updates like your phone, the large center display was responsive with a UI that actually made sense and was closer to an iPad experience than a car.

Tesla also integrated its software into its retail experience, service, and manufacturing.
David Lau deserves a lot of the credit for that.
He joined Tesla in 2012 as a senior manager of firmware engineering and quickly rose through the ranks. By 2014, he was promoted to director of firmware engineering and system integration, and in 2017, he became Vice President of software.
Lau listed the responsibilities of his team on his LinkedIn:
Vehicle Software:
Firmware for the powertrain, traction/stability control, HV electronics, battery management, and body control systems
UI software and underlying Embedded Linux platforms
Navigation and routing
iOS and Android Mobile apps
Distributed Systems:
Server-side software and infrastructure that provides telemetry, diagnostics, over-the-air updates, and configuration/lifecycle management
Data engineering and analytics platforms that power technical and business insights for an increasingly diverse set of customers across the company
Diagnostic tools and fleet management, Manufacturing and Automation:
Automation controls (PLC, robot)
Server-side manufacturing execution systems that power all of Tesla’s production operations
Product Security and Red Team for software, services, and systems across Tesla
Bloomberg reported today that Lau told his team he is leaving Tesla. The report didn’t include reasons for his stepping down.
Electrek’s Take
Twelve years at any company is a great run. At Tesla, it’s heroic. Congrats, David, on a great run. You undoubtedly had a significant impact on Tesla and software advancements in the broader auto industry.
He is another significant loss for Tesla, which has been losing a lot of top talent following a big wave of layoffs around this time last year.
I wonder who will take over. Michael Rizkalla, senior director of software engineering and vehicle firmware, is one of the most senior software engineers after Lau. He has been at Tesla for 7 years, and Tesla likes to promote within rather than hire outsiders.
There are also a lot of senior software execs working on AI at Tesla. Musk has been favoring them lately and he could fold Lau’s responsibilities under them.
