A Swiss startup is using reclaimed wind turbine blades instead of metal beams as horizontal supports for solar panels.

Solar panels, meet wind turbine blades

Founded in 2022, Turn2Sun is based in Neuchâtel and calls its use of second-life wind turbine blades to support solar panels “Blade2Sun.”

The company explains, “The strength of the blades enables structures with broad wingspan, covering large areas with minimal ground use, thanks to spaced-out foundations. This in turns lets you install large PV arrays with reduced impact on the land underneath.”

Turn2Sun and the federal department Armasuisse partnered up and carried out a pilot in Grisons, in the Swiss Alps (pictured above), at an altitude of 2,500 m (8,202 feet). The prototype had around 16 430-watt solar panels attached to 8.4-meter (27.5-foot) wind turbine blades.

The Alpine pilot confirmed that Blade2Sun is feasible, even in extreme conditions.

Why use blades this way?

There are more than 340,000 wind turbines currently installed worldwide. In Europe alone, around 25,000 wind turbines will reach end-of-life in the next few years.

Although it’s possible to recycle more than 95% of a wind turbine’s components, the blades are still challenging to recycle, as they’re made from composite materials (mostly fiberglass). As a result, used blades are mainly burned in cement plants or incineration plants. Wind turbine blades’ exceptional resistance properties that allow them to cut through the air at over 300 km/h (186 mph) could be used differently, as Invest Western Switzerland points out.

So what’s next for this creative use of old wind turbine blades? Lionel Perret, cofounder of Turn2Sun, said:

Several global players are interested in our solution. We’re developing partnerships to be able to offer the solution in other countries, also integrating larger wind turbine blades.

What do you think of giving old wind turbine blades a new life as solar support? Let us know in the comments down below.

Aptera (SEV) shows off assembly line for solar electric 'car', updates on battery and testing

Solar electric vehicle startup Aptera Motors released a new update today, giving us a first look at its validation vehicle assembly line, along with progress on battery production and efficiency testing as it moves closer to its goal of low-volume production.

The update comes just weeks after the company began trading on the Nasdaq under the ticker symbol $SEV.

The move, along with a deal to sell some shares, secured access to up to $75 million in financing for Aptera, which was struggling financially.

It enabled Aptera to get busy, and now the company has released an update about its progress over the last few weeks.

You can watch the full update video here:

On the personnel front, highlighting an expanded team across engineering, operations, and manufacturing. In the video, several new hires introduced themselves, including directors of supply chain and various engineers, signaling that the company is trying to staff up for the next phase.

But the meat of the update is on the manufacturing floor.

Aptera’s Validation Assembly Line

Steve Fambro, Aptera’s co-CEO, walked us through the facility, which he says is now “buzzing with activity”, with a few interesting time-lapse videos that showed progress.

The company has begun the buildout of its validation vehicle assembly line.

Unlike the hand-assembled prototypes we’ve seen in the past, Aptera says this new setup is designed to operate as a “normal vehicle manufacturing line” with a multi-step process. This includes receiving, inventory, kitting, and progressive installation of vehicle systems at individual stations.

At the heart of this new line is a large-scale precision assembly fixture. This is a critical piece of equipment for Aptera’s unique two-piece composite body structure.

Fambro explained the importance of this fixture:

“It’s a major step forward from the original hand-assembled approach we used on the BinC (Body in Carbon) for the first three validation vehicles. With this new fixture, we can now assemble BinCs with far greater repeatability and tighter control over final geometry.”

We also got a look at the frames, which Aptera says are robust and optimized for weight and strength.

Battery Production and ‘Gemini’ Testing

Another significant update is the battery assembly. Aptera’s battery partner, CTNS, is now on-site building battery modules.

This is the first time CTNS has assembled modules directly in Aptera’s facility. The video shows what look to be clean, precise modules ready for integration. This is a good sign for the supply chain, as the battery pack is often a major bottleneck for EV startups.

On the testing front, Aptera has been conducting internal efficiency evaluations with “Gemini,” its third production-intent vehicle.

The company claims preliminary results from combined drive cycles (high speed, stop-and-go, urban) are “encouraging.” They plan to move to more formal regulatory testing soon with the new and bigger fleet of validation vehicles.

Electrek’s Take

This is a nice progress update from Aptera. I am cautiously starting to get hope that Aptera might end up delivering a few of these vehicles.

Now, let’s be honest, there’s still a lot of work to do. The assembly line that Aptera showed today is clearly a work in progress.

$75 million might sound like a lot, but it’s nothing in the automotive manufacturing industry.

The question remains whether that capital will be enough to get them through this validation phase and into meaningful low-volume production.

As a disclosure, I have a small amount of Aptera shares from the crowdfunding days. I’ve always said I don’t see a significant chance of success, but I wish it, as I love the company’s ethos of efficiency.

Kia previews the EV2, its most affordable electric vehicle yet [Images]

With its official debut just around the corner, Kia offered a closer look at the EV2. The new electric SUV will be Kia’s smallest, most affordable EV to date.

Kia confirms the EV2 will debut as its most affordable EV

Kia confirmed that the EV2, its new electric B-segment SUV, will debut at the Brussels Motor Show next month. The EV2 will sit below the EV3 as Kia’s new entry-level electric car.

“With the EV2, we reaffirm our commitment to make electric mobility truly accessible to a broader audience – without compromise,” Kia Europe president and CEO, Marc Hedrich, said on Tuesday.

The EV2 will be built at Kia’s sole European manufacturing plant in Zilina, Slovakia, to speed up production and deliveries.

Designed, developed, and soon to be made in Europe, Kia is confident that the EV2 will play a “pivotal role” in the shift to cleaner, more sustainable travel.

Although it’s the smallest EV in its lineup, Kia promises it won’t feel like it when you’re inside. The interior design is inspired by “a picnic in the city,” according to Kia, with flexible seating and smart storage options that can open up to create a retreat from the busy city life.

Kia has yet to reveal prices or final specs, but given the EV3 is around 4,300 mm (169.3″) long, the EV2 is expected to be slightly shorter at about 4,000 mm (157″).

That’s about the length of the Hyundai Inster (3,825 mm). However, previous spy shots show the EV2 has a more upright stance than the Inster, closer to Kia’s larger SUVs, like the EV9 and EV5.

The EV3 is on sale in Europe, starting at about €36,000 ($42,000), so EV2 prices will likely start at closer to €30,000 ($35,000).

Based on Hyundai’s E-GMP platform, the Kia EV3 is available with 58.3 kWh and 81.4 kWh battery options, providing a WLTP range of 410 km (255 miles) and 560 km (348 miles), respectively. The EV2 is likely to be offered with similar battery pack options.

Kia will unveil the EV2 during a press conference on Friday, January 9, 2026, starting at 10:40 am (CET). Check back for more info leading up to the event. We’ll keep you updated with the latest.

Tesla hints at new camera upgrade, casting more doubt on Full Self-Driving promises

Tesla hints at new camera upgrade, casting more doubt on Full Self-Driving promises

Tesla appears to be preparing to introduce yet another new camera sensor to its hardware suite, according to code found in the automaker’s latest firmware. While hardware improvements are generally good news, this latest discovery adds to the mounting evidence that Tesla is continuously moving the goalposts for self-driving, potentially leaving millions of owners with “older” hardware in the dust… again.

The discovery comes from longtime Tesla hacker and researcher @greentheonly, who frequently digs into Tesla’s software updates to find unannounced features and hardware changes.

According to Green, Tesla’s firmware now references a new sensor model: IMX00N.

Looks like Tesla is changing (upgrading?) cameras in (some?) new cars produced.

Where as HW4 to date used exterior cameras with IMX963, now they (might potentially) have something called IMX00N.

This would ostensibly replace or complement the Sony IMX963 sensors currently used in Hardware 4.0 (AI4) vehicles. The IMX963 is the 5-megapixel sensor that replaced the 1.2-megapixel Aptina sensors found in Hardware 3 cars just two years ago.

We don’t have the specifications for the “IMX00N” yet. It could be a custom Sony SKU for Tesla or a placeholder name for a new image sensor.

Here are the specs comparisons between the camera sensors in HW3 and AI4 Tesla vehicles:

Specification Hardware 3.0 (HW3) Hardware 4.0 (AI4) Technical Implication
Sensor Resolution 1.2 Megapixels (1280 × 960) ~5 Megapixels (2896 × 1876) 4X Data Density. Allows detection of objects at >300m and digital cropping.
Sensor Model Onsemi AR0136AT Sony IMX490 (Estimated) Flagship Automotive Sensor. Simultaneous HDR & LFM.
Color Filter Array RCCC (Red-Clear-Clear-Clear) RGGB (Red-Green-Green-Blue) Semantic Fidelity. True color perception for signs, lights, and road markings.
Dynamic Range ~110 dB >120 dB (Single Exposure) Contrast Mastery. No motion artifacts in tunnel exits or night driving.
Data Interface FPD-Link III (Likely) GMSL2 or MIPI A-PHY High Bandwidth. Supports uncompressed 5MP streams at high frame rates.
Front Cameras 3 (Main, Narrow, Wide) 2 (Main, Wide) Optical Simplification. Digital zoom replaces the physical telephoto lens.
Lens Coating Standard Deep Red IR Cut / Anti-Glare Glare Mitigation. Reduces blinding from headlights and sun.
Heaters Passive (Waste Heat) Active Heating Elements All-Weather Resilience. Rapid defogging and de-icing.
Retrofit N/A Impossible for HW3 cars Fleet Fragmentation. HW3 cars are permanently hardware-limited.

Electrek’s Take

Of course, you would expect Tesla to improve its vehicles, including its sensor suite, gradually. It is a good thing in and of itself.

There are three problems with Tesla updating its hardware suite for autonomous driving:

  1. It promised to all owners since 2016 that their vehicles have all the required hardware to achieve “Full Self-Driving,” and at the time, CEO Elon Musk said that it would mean “unsupervised self-driving.”
  2. It has yet to achieve that, and it promised to offer free hardware retrofit if needed, but it has yet to offer those.
  3. When Tesla launches a new autonomous driving hardware suite, it rapidly puts less effort into software that works with its previous hardware suite.

If the current cameras in HW4 (let alone HW3) are sufficient for Level 4 autonomy, why is Tesla spending resources to integrate a new sensor? The most logical answer is that the current sensors have limitations, whether it’s glare handling, low-light performance, or resolution, that limit the system’s reliability.

If that’s the case, can we expect Tesla to update all the vehicles that are supposed to have the hardware to reach level 4? I wouldn’t bet on it.

CEO Elon Musk already admitted that the HW3 computer won’t support it back in January 2025, almost a year ago, and instead of announcing a solution, Tesla owners were only promised a “mini version” of FSD v14, which itself is not the promised unsupervised self-driving.

At this point, it’s hard to put hope on Tesla doing the right thing here.
