New Zealand’s first solar-powered electric, stratospheric aircraft was launched using an Audi e-tron S Sportback. The “Kea Atmos Mk1” from Kea Aerospace is designed to collect high-resolution aerial data to monitor the weather, tree health, and pollution, among other agricultural uses.

Kea Aerospace has been building and flying electric-powered aircraft to collect insights and data to improve life on Earth.

Being solar-powered with zero emissions, the Kea Atmos is the perfect tool for climate change research. The company envisions its solar-powered Kea Atmos giving the complete picture needed to monitor the land, waterways, and coastline in order to protect it for the future.

The Kea Atmos Mk1 is an uncrewed aircraft with a 12.5-meter wingspan and can fly higher than most commercial airliners at up to 50,000 feet for up to 16 hours, weighing less than 90 lbs (40 kg).

Commercial aircraft generally operate at altitudes between 33,000 and 42,000 ft, whereas Kea’s solar-powered aircraft can operate above the weather and jet stream.

Meanwhile, with satellites typically operating at least 20 times further from the Earth, the Kea Atmos can take over 20 times better images with a similar camera.

Kea has been testing electric prototypes for several years. The first (X1) was in December 2021, flying for 14 non-stop hours. Then, in February 2022, the company achieved a 36-hour flight with its X10 prototype.

CEO of Kea Aerospace says it’s been an “exhilarating year,” taking on several flight tests and showcasing the technology to several NASA executives.

Last month, the company launched the Kea Atmos Mk1 solar and electric-powered aircraft using an Audi e-tron to get it off the ground. Check out the video of it below.

The company says future versions of the solar-powered aircraft will unlock higher altitudes with continuous flight for months at a time.

Kea is developing the long-flight endurance Kea Atmos Mk2 with a wingspan of roughly 30 meters that can operate at an altitude of 65,000 feet. The company says it will use the data for several applications, including:

  • Detecting pollution on land and in the water
  • Monitoring vast forest areas and tree health
  • Enabling rapid response and preparation for extreme weather events
  • Developing smart cities with better traffic flow and green spaces
  • Reducing water and fertilizer with precise agricultural tools
  • Monitoring maritime areas to spot illegal fishing boats and vessels

Truckers are ready to embrace battery power TODAY – but it’s not what you think

Truckers are ready to embrace battery power TODAY – but it's not what you think

A new whitepaper by heavy truck makers PACCAR and Dragonfly Energy that incorporates real-world fleet trial data and Environmental Chamber Testing conducted at the PACCAR Technical Center seems to indicate that over-the-road truck drivers are ready to embrace battery power and reduce emissions – just not while they’re driving.

The whitepaper, titled Reducing Idle Time & Fuel Costs: Lithium Powered Solutions for Commercial Fleets, looked at different ways to reduce harmful diesel emissions across the duty cycles of a number of different fleet operations, and what they found was that powering a truck’s auxiliary and cabin systems with a high-voltage lithium-ion battery dramatically reduced engine idle time even under worst-case operating scenarios.

Another report by a group called the Clean Air Task Force showed that idling heavy-duty diesel engines while drivers are “hoteling” in their trucks (they’re parked, but running the engine to power the sleeper cab’s climate controls, kitchens, or electronics) exacts a heavy toll on both drivers and shipping fleets.

Idling not only burns fuel and increases operating costs at 0 MPG, it also emits a dangerous cocktail of harmul pollutants that pose direct health risks to drivers, rest stop employees, and nearby communities. Diesel exhaust contains fine particulate matter (PM), nitrogen oxides (NOₓ), and numerous airborne toxins that are known carcinogens, making them a serious problem even to those who think climate change is a global conspiracy from “Big Science” to keep those plucky young oil billionaires in the place.

From a mechanical standpoint, extended idling also accelerates engine wear, degrades emission-control systems, increases maintenance, and shortens engine life.

By adding a relatively high capacity hybrid battery (like Dragonfly Energy’s Battle Born brand batteries) to the something like a PACCAR Kenworth T680 (at top), drivers can stay parked for several hours, operating their sleepers’ refrigerators, ACs, or heaters without the noise and emissions and costs of diesel – and they probably sleep better too, without the drone of neighboring diesels cranking on around them all night.

“We believe idle reduction remains one of the most immediate and cost-effective ways fleets can reduce fuel consumption and emissions while improving driver comfort. But just as important, the industry is increasingly focused on operational efficiency and maximizing asset utilization,” explains Wade Seaburg, chief commercial officer at Dragonfly Energy. “We believe our collaboration with PACCAR not only validates the performance of our LiFePO₄-powered solutions, but also highlights how they help fleets maximize uptime, extend equipment life and get more out of their assets.”

The electrification of the auxiliary systems also reduces engine hours, stretching out the time between scheduled maintenance and reducing operational downtime.

In other words, the hybridization of OTR trucks is a win-win-win. The full whitepaper is available for download at BattleBornBatteries.com/Lithium-Powered-Idle-Reduction. Take a look at it yourself, then let us know what you think of the idea in the comments.

Renault says a desirable $20,000 EV is coming – and it’s NOT made in China

Renault says a desirable ,000 EV is coming – and it's NOT made in China

French car brand Renault believes they’ve got the key to more affordable EV batteries, and their new LFP tech promises to slash the costs of production by 40%. The result? New, desirable EVs with a sub-20K price tag that aren’t made in China.

Spanish news site Motorpasión is reporting that Renault, like Ford, is embracing a more affordable lithium-iron phosphate (LFP) battery chemistries that are safer, cheaper, and less dependent on rare mineral mining than conventional li-ion batteries.

That’s a big change from the recent past. Because they’re less energy dense and weigh a bit more than comparably-sized lithium-ion NMC (nickel-manganese-cobalt) batteries, European automakers looked down on LFPs. But with Chinese automakers like BYD, MG, and Leapmotor flooding Europe with affordable LFP-powered EVs, that stigma is fading fast.

Fun, affordable LFP vehicles


The stability, battery life, and cost advantages of LFP have become too compelling to ignore — especially as global lithium and nickel prices continue to fluctuate, making long-term business projections difficult. Renault’s decision to embrace LFPs then, is less about catching up on the Chinese’ technology than it is about catching up catching up on the Chinese’ economics, and acknowledging that affordability is the real barrier to mass adoption.

That was the thinking behind Renault’s relaunch of the R5 E-TECH (sold as the Le Car in the US) and the announcement that a new Twingo would be coming soon.

It was also the thinking behind the French carmaker’s decision to launch the new Ampere vehicle software development sub-brand back in 2023. At the time, the stated goals were to improve (what are now called) Renault’s software-defined vehicles and, separately, to reduce manufacturing costs of new EVs by 40% – which, if you’ll notice, is just about what the switch to LFP chemistries will enable them to do.

“Creating a new model of company specializing in electric vehicles and software running as of today: How better to illustrate our revolution and the boldness of our teams?” asked Luca de Meo, Renault Group CEO, at Ampere’s launch. He answered his own question, saying, “Instill a sustainable corporate vision and ensure it is reflected in each and every process and product. Build on the Group’s strengths and review the way we do everything. Form a tight-knit team and work for the collective. Harness our French roots and become the leader in Europe. Assert our commitment to our customers, our planet and those living on it.”

Renault is set to launch an all-new, all-electric version of its iconic Twingo minicar from the 1990s in the next few months (at top). The car is targeted straight at the BYD Dolphin and is expected to have a starting price of about €17,000 (just under $20,000 US).
