A little bit of background: the Northern Territory covers almost one and a half million square kilometres (or 520,902 square miles), and has a population of only 246,500. 49% of the land in the Northern Territory is owned by the indigenous population. The economy is based largely on mining and petroleum. Most of the population lives in Darwin, the capital, with a spread of settlements along the Stuart Highway heading down to Adelaide. The north of the territory is tropical savannah, the south is desert. It is not a state — has a legislative assembly but can be overruled by the Commonwealth.

I’ve only travelled to the Northern Territory once. A couple of decades ago, I flew from Brisbane to Uluru (then known as Ayers Rock). One could not help but be impressed by the vastness of the place, and the heat! We visited the rock at dawn (it was too hot otherwise) and even drank champagne with a motorcycle group at sunset. Now the Northern Territory is in the news for other reasons.

It is implementing a plan to support the introduction of electric vehicles. The Northern Territory government will charge reduced registration and stamp duty fees for electric vehicles; give grants for home, workplace and public EV chargers; and facilitate the installation of more EV charging stations.
“Implementation of this electric vehicle policy confirms our Government’s actions on addressing climate risk to transition to a low-carbon economy. Responding to climate change will not only help us protect our environment, but will support this new industry and the jobs that come with it,” Ms. Lawler, Minister for Renewables and Energy, said.
Tapping into the territory’s rich solar resources and vast open spaces (no need for NIMBYism here) many projects are being planned to transform the Northern Territory into a renewable energy powerhouse. Australia’s Beyond Zero Emissions (BZE) has a “10 Gigawatt Vision for the Northern Territory,” with massive job creation potential and a future in the export of green hydrogen.
The Northern Territory has set a 50% renewable energy target. Part of its success will depend on big batteries and more and more solar. A 35MW big battery is planned for Darwin to displace current dependence on gas generation. The federal government is supporting the push with a $37 million loan from the Northern Australia Infrastructure Facility (NAIF) to create a 10MW solar and battery station being built south of Darwin.
Jabiru, gateway to Kakadu National Park (think lots of crocs!!), has no grid connection. Energy Developments Limited is building a hybrid diesel, solar, and battery microgrid to power the town. It is expected to be fully operational by February 2022.
The Northern Territory contains the heart of the Australian Nation (Uluru). This heart is now going solar.

A canton in Switzerland commissioned a project in which solar panels were attached vertically to a roadside retaining wall.
The canton of Appenzell Ausserhoden in northeastern Switzerland is aiming to generate at least 40% of its electricity from renewables by 2035. So, it exercised a little creativity and covered a roadside retaining wall with 756 glass-glass solar panels.
The panels have an output of 325 kW and an energy yield of around 230,000 kWh annually. This is equivalent to the consumption of about 52 Swiss households. The energy will be fed into the grid of energy supplier St. Gallisch-Appenzellische Kraftwerke, and the canton will get a feed-in tariff in return.
German mounting system provider K2 Systems and Swiss contractor Solarmotion installed the vertical system on the 75-degree retaining wall. The panels were anchored on a mounting rail with HUS screw anchors, and Lichtenstein-based Hilti provided mechanical dowels.
The PV system was anchored on and in the masonry using an adhesive technique. An anchoring depth of a maximum of 90 mm could not be exceeded so that the retaining wall would not be adversely affected.
Due to the close proximity to the asphalt, the solar panels’ components are subject to exceptional corrosion requirements and are anodized for protection. Indirect components are made of aluminum – only the screw anchors are made of stainless steel.
K2 Systems says that “especially in the winter months (when consumption and dependence on foreign electricity imports are at their highest), the vertically aligned modules will achieve a very good electricity yield.”
Electrek’s Take
This isn’t a big project, but it’s a delightfully creative one, which is why it caught my eye. A retaining wall is dead space, and snow will slide off the panels in Swiss winters.
We at Electrek love it when solar is installed in intelligent and inventive ways. Warehouse rooftops? Cover them. Highway medians? Canal covers? Box stores? Put solar on them. It just makes sense.

Flying electric cars are not just for sci-fi movies. Miami-based Doroni Aerospace announced Friday its all-electric flying car, the Doroni H1, received official FAA Airworthiness Certification. And the best part – it’s designed to fit in your garage.
Doroni’s all-electric flying car gets FAA-certified
Doroni claims to be the first company to test manned flights with a 2-seater flying electric car in the US. The Doroni H1 took flight earlier this year.
CEO Doron Merdinger successfully piloted the personal electric vertical takeoff and landing aircraft (eVTOL) this summer. Merdinger said receiving the flight certification “is not just a milestone for our company, but a leap forward for the entire field of personal air mobility.”
He says the electric flying car “is poised to redefine urban transportation.” Doroni’s aircraft has already received over 370 pre-orders as the startup wraps up funding efforts.
Powered by ten independent propulsion systems, the all-electric flying car has a claimed top speed of 140 mph (100 mph cruising speed) and 60 miles range. Its unique design ensures stability during flight.

It includes four ducts containing two e-motors with patented ducted propellers. Eight are for vertical flight with an additional “two pushes.”
The two-seater aircraft is designed to fit inside a two-car garage at 23 ft in length and 14 ft in width. It also features fast charging (20% -80%) in under 20 minutes.

Electric flying cars coming to a dealership near you
Doroni’s all-electric flying car is semi-autonomous, meaning you can guide it to different levels. A controller stick is used to push you forward, backward, or to the side.

Who would buy one of these? Doroni says one of its customers is a doctor who wants to use the aircraft to skip traffic on their way to work. However, you will need a certification. It requires at least 20 hours of experience, 15 inside the aircraft and another five solo.
Merdinger says the biggest use case for eVTOLs will be for air taxis or ride-sharing. Doroni aims for a different market though.

The company says there is enough space to fly everywhere, especially in suburban areas. Doroni’s all-electric flying car is designed for more than just getting you from point A to point B. It allows you to “enjoy nature,” according to Merdinger.
Doroni expects to build about 120 to 125 units by 2025 or 2026. Eventually, the Miami-based startup plans on scaling to produce 2,500 eVTOLs annually. You can learn more about the electric flying car on Doroni’s website.
(Source: Alef Aeronautics)
The company is the latest to receive the flight certification. Alef’s Model A was the first electric flying car to get certfied in June.
Alef said it had 2,500 pre-orders in July. The orders include 2,100 from individuals and 400 from businesses, including a California car dealership.
Electrek’s Take
Are electric flying cars going to take over road transportation? Not necessarily. At least not anytime soon.
Doroni and Alef are both working on niche markets, which makes the most sense for the time being. At the same time, the companies are pushing forward another sustainble means of transport.
As Merdinger explained “this is just the beginning,” as the technology advances.

Tesla’s Cybertruck website included a revelation about a feature that wasn’t mentioned in its presentation: a “range extender,” in the form of an additional battery pack in the truck bed which expands the truck’s range.
It’s an interesting solution, and we don’t know all the details of it yet. We don’t know the cost, the weight, how it will be installed and uninstalled, or whether it even can be uninstalled.
The battery pack is intended to be used “for very long trips or towing heavy things up mountains,” according to Tesla CEO Elon Musk. It takes up about a third of the truck bed, as can be seen in a photo posted on Tesla’s Cybertruck site.
So, there’s still room for cargo, just not the full 6 feet of bed length that Tesla says the Cybertruck has.
But the fact that it was described as being used only “for very long trips or towing heavy things up mountains” suggests that it will be removable, since most people don’t do that sort of thing every single day.
Making it removable is actually a good solution, because it can lower prices, make packaging easier, and improve efficiency for vehicles that simply don’t need a ridiculously enormous 470-mile battery – and most drivers don’t need that.
And if it is removable, well, there’s already a patent on that.
An electric vehicle system for transporting human passengers or cargo includes an electric vehicle that includes a body, a plurality of wheels, a cargo area, an electric motor for propelling the electric vehicle, and a primary battery for providing electrical power to the electric motor for propelling the electric vehicle. An auxiliary battery module is attachable to the electric vehicle for providing electrical power to the electric motor via a first electrical connector at the auxiliary battery module and a second electrical connector at the electric vehicle that mates with the first electrical connector. The auxiliary battery module can be positioned in the cargo area while supplying power to the electric motor, and can be removable and reattachable from the electric vehicle. The auxiliary battery module includes an integrated cooling system for cooling itself during operation of the electric vehicle including a conduit therein for circulating coolant.
We aren’t patent lawyers here, but this sounds awfully similar to Tesla’s “range extender.” The obvious potential differences we can find are if the range extender doesn’t have integrated cooling, which is unlikely, or if the range extender isn’t removable, which doesn’t seem to jive with the statement that it is only for long trips or with the marketing showing it as an optional add-on (if that were the case, why not just offer different battery sizes?).
So next, the question is: is Tesla’s solution different enough to avoid Rivian’s patent protection? Has Tesla licensed the idea from Rivian, and we just haven’t heard about it yet? Or will Rivian return Tesla’s “good faith” and not initiate a patent lawsuit against Tesla, if it does feel like it has a good enough case to say that Tesla’s range extender infringes on its patent?
