Ocean Oasis’ Gaia system has been designed to use wave power to desalinate water.
Ocean Oasis
Plans to use marine energy to desalinate water received a further boost this week, after a Norwegian firm presented a system that will be put through its paces in waters off Gran Canaria.
In a statement Monday, Oslo-headquartered Ocean Oasis said its wave-powered prototype device, which it described as being an “offshore floating desalination plant,” was called Gaia.
The plant — which has a height of 10 meters, a diameter of 7 meters and weighs roughly 100 tons — was put together in Las Palmas and will undergo testing at the Oceanic Platform of the Canary Islands.
Ocean Oasis said its technology would enable “the production of fresh water from ocean waters by harnessing the energy of the waves to carry out a desalination process and pump potable water to coastal users.”

The company said the development of its prototype had received financial backing from a range of organizations including Innovation Norway and the Gran Canaria Economic Promotion Society.
The main investor in Ocean Oasis is Grieg Maritime Group, which is headquartered in Bergen, Norway.
Desalination
The Canary Islands are a Spanish archipelago in the Atlantic Ocean. According to the Canary Islands Institute of Technology, the islands have been “a pioneer in the production of desalinated water at affordable cost.”
A presentation from the ITC highlights some of the reasons why. Describing the Canary Islands’ “water singularities,” it refers to a “structural water deficit due to low rainfall, high soil permeability and aquifer overexploitation.”
While desalination — which multinational energy firm Iberdrola describes as “the process by which the dissolved mineral salts in water are removed” — is seen as a useful tool when it comes to providing drinking water to countries where supply is an issue, the U.N. has noted there are significant environmental challenges linked to it.
It says that “the fossil fuels normally used in the energy-intensive desalination process contribute to global warming, and the toxic brine it produces pollutes coastal ecosystems.”
Stock picks and investing trends from CNBC Pro:
With the above in mind, projects looking to desalinate water in a more sustainable way will become increasingly important in the years ahead.
The idea of using waves to power desalination is not unique to the project being undertaken in the Canaries. In April, for example, the U.S. Department of Energy revealed the winners of the last stage of a competition focused on wave-powered desalination.
Back on the Canary Islands, Ocean Oasis said it would be looking to construct a second installation after testing at the PLOCAN facility had taken place. “In this phase, the prototype will be scaled with the capacity to produce water for consumption,” the company said.
While there is excitement about the potential of marine energy, the footprint of wave and tidal stream projects remains very small compared to other renewables.
In data released in March 2022, Ocean Energy Europe said 2.2 megawatts of tidal stream capacity was installed in Europe last year, compared to just 260 kilowatts in 2020.
For wave energy, 681 kW was installed, which OEE said was a threefold increase. Globally, 1.38 MW of wave energy came online in 2021, while 3.12 MW of tidal stream capacity was installed.
By way of comparison, Europe installed 17.4 gigawatts of wind power capacity in 2021, according to figures from industry body WindEurope.
Porsche unveiled its new Cayenne EV today, and it comes with an option for something we haven’t seen out of a factory-equipped car before: inductive charging.
Over the years, we’ve heard plenty of attempts by companies to trick consumers into thinking that it’s possible to make an electric car that doesn’t need to charge.
From Toyota’s dumb “self-charging hybrid” claim, to the new fad of “range extenders”/EREVs (aka plug-in hybrids with a bigger battery), to all manner of solarvehicles, people seem to think that convincing customers that they don’t need to plug in will get them to buy an EV (or, will help them greenwash their gas-guzzling hybrids).
And now the next entry into that group has arrived: the Porsche Cayenne electric, which can indeed be driven without ever plugging in, or gassing up, or even parking in the sun.

It does have to be parked somewhere specific though: over a pad in your garage. Because this car can be equipped to use inductive charging, right out of the factory.
Inductive charging uses magnetic fields to transfer electrical power, as opposed to conductive charging, which uses a plug. Inductive charging is how phone charging mats work, but in this case, it’s scaled up significantly in size and power.
We’ve seen a few inductive charging projects before, but they’ve always been aftermarket or experimental so far. Or, they’ve been targeted more at commercial or fleet buyers (buses, for example).
Porsche says that its inductive charging system can push 11kW of power, which is plenty for overnight home charging (on the car’s 113kWh battery). It does this at 90% efficiency – not as much as the ~95% of conductive charging, but still quite good. It also requires an extra ~33lbs of coils and wiring onboard the car, which is a significant if not massive weight gain.
To activate the system, the charging pad makes contact with the car via wide-band wireless communication to determine location, then activates when you park in just the perfect spot. The car’s screen shows guide lines to help you find the way to where you need to be – or there’s always the tennis-ball-on-a-string trick if you want to go low tech.
When we tried it out in LA, once we got the system up and running (hot tip: don’t daisy chain two extension cords if you want your inductive charging pad to work), it quickly charged at 11kW, at least according to the in-car system.
The inductive charger includes a lot of safety features to ensure nothing weird happens. Even though it only uses magnetic fields, the mat includes sensors to detect any living or metal objects nearby, it will stop (yes, this includes your cat that likes to sleep under the car, and yes, Porsche gets asked this question often). We saw this happen once in the studio demo, but it quickly turned back on after deciding everything was okay.
The Cayenne will still have its regular conductive charging ports, capable of 11kW AC or 400kW DC charge. But for those who want to forgo the plug, at least at home, the mat is an available option.
That said – pricing and availability are still TBD. The system costs €7k in Europe, plus an electrician, but we don’t know what it will cost in the US yet.
So, there’s still a chance that someone else beats Porsche to the “first” moniker – possibly Tesla, given that it seems to be close to offering an inductive charging system. But there are a lot of hurdles to ensure that the system is reliable in every type of weather and real world situation, and lots of electrical codes to follow. So, it looks like the race is on.
Electrek’s Take
I was quite interested in talking to the engineers about this system, because I hadn’t actually experienced inductive charging in an EV before.
People have been talking about this for a long time, and I used to be excited about the concept of electrified roads where cars could just drive on them and get a charge and never have to plug in.
However, after conversations over the years and experience with how easy driving and charging an EV is, I came to think that inductive charging is mostly a gimmick, and that we will likely rely on conductive charging in the long term (and especially that in-highway charging is a boondoggle that’s never going to be a good option, especially when catenary/pantograph systems exist).
That said, there are still niches and benefits to be had. In a potential fully autonomous future, we’ll need to figure out autonomous charging, and inductive charging could be a good answer for that.
In addition, some drivers do have difficulty with cables. While the NACS cable is much easier to handle than the old CCS cable, an older driver or one with mobility issues might have a hard time plugging in a car. Inductive charging could be good for them.
Or, heck, maybe someone is just lazy. Or doesn’t like cords. And doesn’t mind spending money for these marginal improvements. We can imagine there are Porsche buyers who could fit that description.
I still think the take rate will be relatively low, but it will be interesting to see real world tests of this, how buyers get along with it, and what sort of problems they manage to solve. As much as I’m a skeptic of inductive charging’s usefulness and acknowledger of its limitations, it’s nice to see new things get tried sometimes.
What do you think about Porsche’s inductive charging system? Would you prefer it to conductive charging? How much would you pay to add this option to your EV? Let us know in the comments.

The Inster, Hyundai’s most affordable EV, is Germany’s best-selling small electric car and top overall vehicle priced under €25,000.
The Hyundai Inster is Germany’s best-selling small EV
After launching the Inster in Europe in late 2024, Hyundai’s smallest and most affordable EV quickly became one of the most popular electric cars in the region.
According to JATO Dynamics, the Hyundai Inster was the 19th most popular EV across Europe in June, outselling the Dacia Spring, Hyundai Kona, and Toyota bZ4X.
In Germany, the heart of Europe, Hyundai’s most affordable EV is making an even bigger impression. Since this summer, the Hyundai Inster is Germany’s best-selling small EV so far in 2025 and just won the Golden Steering Wheel award for best car under €25,000 ($28,900) by AUTO BILD & BILD am SONNTAG.

The award comes after the Inster was crowned the 2025 World Electric Vehicle at the World Car Awards ceremony in the spring, held during the New York International Auto Show.
Hyundai’s electric city car starts at just €25,000 ($28,900) in Germany. Despite its small size, the Inster delivers up to 370 km (230 miles) WLTP driving range, fast charging (10% to 80%) in 30 minutes, and a surprisingly spacious and feature-rich interior.
The Inster features dual 10.3″ driver display and infotainment screens with wireless Android Auto and Apple CarPlay as part of Hyundai’s digital cockpit.
By 2027, Hyundai plans to electrify all vehicles sold in Europe. The Inster and IONIQ 9 are now rolling out across the region, and Hyundai plans to build momentum with new EVs, including the IONIQ 3, which will go into production in Hungary in the first half of 2026.

In South Korea, Hyundai’s home market, the Inster is sold as the Casper Electric. The compact EV is sold in Japan, Europe, the Middle East, and parts of Asia.
Although those in the US won’t get to see the Inster or IONIQ 3, Hyundai still has one of the most affordable EVs you can get your hands on. With leases starting at just $189 per month, the Hyundai IONIQ 5 is still America’s best deal for an electric vehicle.
MP Materials surged Wednesday on a deal with the U.S. Department of Defense and the Saudi Arabian Mining Company, Maaden, to develop a rare earth refinery in the kingdom.
The U.S. rare earth miner’s stock was last up about 9%.
MP and the Pentagon will hold a 49% stake in the joint venture, the company said. Maaden’s position will be no less than 51%. The Defense Department will finance the U.S. portion of the venture with MP providing technical and marketing expertise.
The binding agreement to form the joint venture comes after MP and Maaden signed a memoranum of understanding back in May. The agreement will “significantly expand MP’s global footprint” and is structured to “ensure U.S. oversight and alignment with national security objectives,” the company said.

MP is also holding talks on a possible collaboration to standup magnet manufacuring in Saudi Arabia.
The Pentagon struck a landmark deal with MP in July that includes an equity stake, a price floor, and offtake agreement. The Trump administration is investing in MP as it seeks to reduce U.S. dependence on China for rare earth imports and stand up a domestic supply chain.
MP CEO James Litinsky has described the company as the U.S. “national champion” for rare earths. Rare earths are crucial inputs in U.S. weapons platforms, electric vehicles, clean energy technology, semiconductor manufacturing and consumer electronics.
Goldman Sachs initiated converage of MP on Tuesday with a price target of $77, implying about 32% upside from Monday’s closing price.
“We believe MP’s downstream expansion into refining and magnet production, accelerated by a partnership with the US government, will strategically position MP as a key supply chain component for rare earth refining and magnet production,” Goldman analyst Brian Lee told clients.
