University of Seville scientists have invented a solar-powered bus stop that can lower the temperature by 20C to keep pedestrians cool.

The innovative system has a top unit with solar panels that provide energy to pump water, an underground cistern that stores fresh water at night, a closed circuit that circulates water during the hottest times of day, and temperature sensors that also detect when pedestrians are present.

Here’s how the solar-powered bus stop works: When the sensors detect that a pedestrian has arrived at the bus stop, the pumping system activates. It draws water from the cistern and circulates it, and that lowers the temperature of the bus stop to between 20 and 24C (68 and 75F) by releasing cool air through small holes. The cooling process lasts for 10 to 20 minutes, then the water returns to the cistern. The water flows through the shelter’s roof at night to cool down.

The study’s lead author, José Sánchez, told PV magazine Spain, “It’s not like an air conditioner, which produces cold air; the structure of the bus stop emits freshness, as is the case with refrigerators. Although it consists of more elements, its production is cheaper than common bus stops.”

The pilot is going to launch in Seville in the summer of 2024, and the researchers say that they’ll continue to work on the design to improve it.

The high in Seville today is 43C (109F), so this isn’t just a luxury – it’s providing a much-needed service to protect people’s health in the face of global warming. Or, as the study’s abstract puts it, “Urban space is considered a harsh place for citizens in large cities in Southern Europe due to the climate change situation.”

E-quipment highlight: Liebherr R 920 G8-E electric crawler excavator

E-quipment highlight: Liebherr R 920 G8-E electric crawler excavator

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.

Liebherr has made headlines in the sustainability space with its massive electric haul trucks and stupefyingly quick 6MW cryo-cooled DC fast chargers, but its conventional mid-sized equipment lines haven’t electrified as quickly, leaning instead on hydrogen combustion and fuel cell efforts. That seems to be changing, however, with the launch of the 20-ton R 920 G8-E – the brand’s first-ever factory fresh HDEV.

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.

LIEBHERR

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

If the notion of a battery electric Liebherr excavator seems familiar, that’s because it should – the company first converted one of its ultramassive R9400 mining excavators last year, as a proof of concept co-developed with global mining giants Fortescue as they invest in new technology to decarbonize their mines.

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.

Looks like Rivian is working on a steer-by-wire system

Looks like Rivian is working on a steer-by-wire system

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.

The company posted a job listing for “Sr. Staff Technical Program Manager, Steering Actuator System,” based at its Irvine, CA headquarters (spotted by Rivianforums). This wouldn’t be so exceptional, except that the job posting also specifically points out that “you’ll have full cradle-to-grave ownership of the SBW subsystem.”

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…
