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.

Global mining and construction equipment giant Liebherr recently rolled out its first-ever battery electric crawler excavator, setting a new standard in heavy earth-moving equipment capabilities with low noise levels and zero local emissions.
The company’s official copy is characteristically low-key, with an emphasis on the facts and features instead of hype:
The new model completes the product range of Liebherr crawler excavators produced in Colmar (France). It is particularly quiet and emission-free. It generates the same output as a diesel machine in the same category and is particularly suitable for building sites that require low noise levels and avoiding exhaust gas emissions, such as in cities or underground operating locations.
Despite the lack of excitement in the release copy, there is a lot of excitement about the R 920 G8-E’s innovative new control cab philosophy.

Liebherr INTUSI controls
Dubbed INTUSI (for INTuitive USer Interface), the system integrates intelligent control logic with advanced machine learning capabilities to give operators a highly customizable interface that can follow them from asset to asset, from wheel loader to excavator to haul truck, dramatically flattening the learning curve for operators on a given job site.
Liebherr says INTUSI improves both operational efficiency and user comfort on Liebherr job sites through the integration of a number of new features. From the press release:
Haptic feedback – vibrations alert the operator to critical conditions—such as reaching dynamic device limits—enhancing situational awareness and speeding up reaction times.
Optical feedback – integrated RGB LEDs on the joystick provide real-time visual cues about device status and servo control, ensuring clear communication without distraction.
Functional safety – control elements with status LEDs allow safe operation of critical functions—without requiring two-handed input—streamlining workflow while maintaining safety standards.
Hand detection – capacitive proximity sensor detects the operator’s hand automatically, enabling seamless activation of controls only when needed.
Display navigation – a mini-joystick embedded in the handle allows for quick and efficient navigation of the display interface, reducing the need to reach for external controls.
Ergonomics – multi-stage handle height adjustment ensures optimal comfort and usability, adapting to different operator preferences and working conditions
In addition to the INTUSI-powered custom cockpit, the new Liebherr R 920 G8-E electric excavator ships with your choice of either a 188 or 282 kWh high capacity li-ion battery, which is capable of 150 kW DC fast charging. Fast enough, in other words, to power up the machine during shift changes, if needed.
Electrek’s Take
R 920 G8-E electric crawler excavator; via Liebherr.
Since then, Fortescue has used the machine to move millions of tons of dirt, and has ordered several more. And, because everything from excavators to loaders to heavy trucks are built to be powertrain agnostic, and manufacturers will often offer the same basic vehicle with Cummins, Detroit Diesel, or Volvo power, so there’s a degree of openness baked into those systems already. Liebherr is just taking that to the next level by installing an electric drive motor in place of an internal combustion engine, and I expect this excavator will be the first of many such machines from the brand.

Rivian has posted a job listing for a steering engineer, specifically mentioning work on a future steer-by-wire system for the company.
Steer-by-wire is an automotive concept that has been around for a long time, but hasn’t yet reached mass adoption. The idea is to replace (or supplement) mechanical linkages between the steering wheel and the wheels with electronic actuators instead.
There are a number of potential benefits to this, like allowing more customizability or adaptability to a steering system, reducing mechanical complexity, or adding speed-sensitive variable steering ratios.
Although there are also disadvantages, like a reduction in steering feel (although, since most cars are moving to electronic power steering, that was already gone anyway).

But few cars have implemented steer-by-wire systems, or at least not fully committed to them, given that mechanical steering racks are a relatively solved problem and the general inertia of the car industry which would rather stick with a solution they know than switch to something better (haven’t we here, at this EV publication, heard *that* one before…). There’s also the matter of regulations, which have often been written to require mechanical steering systems, and may need updating to allow for steer by wire.
But, steer by wire made it into mass production with the release of the Tesla Cybertruck. This was big news when Tesla committed to this – at the time, it was the only thing on the road to exclusively use a steer by wire system, though there are other cars with partial steer by wire (for example, mechanical front wheel steering, and steer by wire rear-wheel steering).
But it seems to have opened the floodgates, as a number of other companies are working on or have since released steer by wire systems (Lexus, for example).
And now, it looks like Rivian is one of those companies – though we don’t know if it’s for the front or rear.
So – we know they’re working on steer by wire, to some extent.
But a few other EVs, particularly large EVs like the Rivian R1 platform is, use steer by wire just for the rear wheels – for example the Hummer EV and Rolls-Royce Spectre. These systems are particularly helpful for giant vehicles, because it allows them to be more nimble and make turns that otherwise would require a lot more… negotiation in a giant land yacht.
So it’s possible that Rivian is only working on rear wheel steer by wire here, but we’d like to think there’s a chance it’s working on steer by wire for the full vehicle.
We also don’t know if this would show up on all of Rivian’s vehicles, or only on certain models – the R2 and R3 are in development, and the R1 just got a big refresh. But, perhaps even more interestingly (and very speculatively), VW has invested heavily in Rivian for technology help, so we wonder if we might end up seeing this in VW group vehicles, or Scout vehicles eventually…
