Sea-based trials of a wave energy converter weighing 50 metric tons have produced “highly encouraging results,” according to the company behind its development.
On Tuesday, Scotland-based AWS Ocean Energy said the average amount of power its device was able to capture “during a period of moderate wave conditions” came to more than 10 kilowatts, while it also recorded peaks of 80 kW.
In addition, AWS said its Waveswing was able to operate in more challenging conditions, including Force 10 gales.
The piece of kit — which has been described as a “submerged wave power buoy” — has a diameter of 4 meters and stands 7 meters tall.
The Waveswing, AWS Ocean Energy says, “reacts to changes in sub-sea water pressure caused by passing waves and converts the resulting motion to electricity via a direct-drive generator.”
Compared to more established renewable technologies, the 16 kilowatt Waveswing is small. Firms like Denmark’s Vestas, for instance, are working on 15 megawatt wind turbines.

This phase of testing is set to wrap up before the end of this year, with more tests set to be carried out in 2023.
In terms of real-world applications, AWS Ocean Energy CEO Simon Grey said the Waveswing had features that made it “ideal for remote power applications such as powering subsea oilfield assets and oceanographic monitoring.”
Grey later added that the firm also expected to “develop platforms hosting up to twenty 500 kW units with a potential capacity of 10 MW per platform.”
The sea trials are taking place at a European Marine Energy Centre testing site in the sheltered waters of Scapa Flow, Orkney.
An archipelago, Orkney is located north of the Scottish mainland. EMEC, which is based there, has become a major hub for the development of wave and tidal power since its inception in 2003.
Neil Kermode, who is EMEC’s managing director, said it had been “great to see the Waveswing deploy, survive and operate at our test site this year.”
“We know there are epic amounts of energy in the seas around the UK and indeed the world,” Kermode went on to add. “It is really rewarding to see a Scottish company make such progress in harvesting this truly sustainable energy.”
More from CNBC Climate:
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.
Aptera, the company behind a highly efficient electric vehicle capable of charging from the sun, is about to go public, but its approach raises concerns.
Is it the end of another solar car project?
There have been a handful of “solar car” projects and they all have failed so far.
I put “solar car” in quotes because they are essentially small electric vehicles that are so efficient that adding solar panels can contribute relatively significantly to charging the car.

Aptera is one of the rare survivors, thanks to a couple of relatively successful crowdfunding efforts. The company has been inching closer to bringing its vehicle to production, but it still appears to need some investments to make it happen.
Now, Aptera is going public.
Generally, that’s good news. An initial public offering (IPO) means that a company is going to raise capital for its operations and give more people the opportunity to invest in the company.
However, Aptera is not doing a traditional IPO. It’s not even doing a SPAC deal. It’s doing a direct listing, which means that if approved by NASDAQ, it will allow shareholders to trade their shares on the public market.
This is usually an exit strategy for existing shareholders. Aptera won’t receive any proceeds from going public. They wrote in their SEC filing:
This prospectus relates to the registration of the resale of up to 31,741,948 shares of our non-voting Class B common stock… We will not receive any proceeds from the sale of shares of Class B common stock by the registered stockholders.”
What good could come out of this for the company?
As of the end of June 2025, the last reporting date, Aptera had about $13 million in the bank, and it is burning through more than that in a year – meaning it is running out of cash.
The company needs to be infused with capital soon, and this direct listing is not it.
Meanwhile, Aptera stated that the public listing will not occur until at least October 14, next week, to allow shareholders, including those who invested in the crowdfunding rounds, sufficient time to transfer their shares into their broker accounts and trade them.
Electrek’s Take
As I previously disclosed, I invested a small amount in Aptera’s crowdfunding campaign a few years ago. Nothing I wasn’t entirely willing to lose. I knew and consistently stated that the project would be challenging to bring to market.
I invested because I love the project and wanted to help give them a chance to succeed. I not only like the solar aspect, but also the idea of creating a hyper-efficient vehicle that still retains a relatively high level of utility.
But this smells like the end to me. I’d love to hear your take in the comments below, but I don’t see a way out of this for the company.
I guess there’s a possibility that insiders somehow hold, and there’s some public demand for the stock amid this crazy bubble we are in – resulting in a price increase, which Aptera takes advantage of with a public offering. But that sounds far-fetched, doesn’t it?
What other possible scenarios are there except for the obvious one where current shareholders quickly dump their shares, the stock crashes, Aptera can’t raise capital, and closes its door and sell itself for parts?
While solar cars are cool, the most efficient way to power an electric car with solar energy is to have solar panels on your home. If you are in the US, the next few weeks are likely the last opportunity to secure a solar installation and take advantage of the federal tax credit, which is set to expire.

Japanese equipment giant Kubota has pulled the wraps off a world’s first. The new, Autonomous Fuel Cell Tractor packs electric drive motors powered by a hydrogen fuel cell — one that can get topped off with hydrogen made from farm waste!
As longtime Electrek readers already know: I’m no fan of hydrogen as a transport fuel, but that doesn’t mean it doesn’t work in other applications — and one of those is certainly large-scale farming. In that context, Kubota’s latest announcement feels like a natural sequel to the company’s broader push into electrification and intelligent farming tools.
The company has high hopes for its electric farm equipment, as Japan (like other Western nations) is struggling to attract young people into farming, leading to a continually aging and shrinking workforce and ongoing labor shortage.

“The concept behind this model is to simultaneously achieve environmental sustainability, operational efficiency, and labor saving,” reads the official press copy. “Since only water is discharged during operation, it is environmentally friendly, and is also designed for operation without operators onboard via autonomous driving and remote control.”
You’ve heard all that before. What may be new to you is the notion that hydrogen can be produced locally, by many kinds of farmers, using existing farm inputs that convert biowaste into methane, then reform or electrolyze it into hydrogen. That circular model gives farmers in areas with limited grid access (or a desire to stay off the grid, for their own reasons) a viable way to generate and store energy.
Energy that, unlike the electricity from solar panels, can power modified reciprocating engines like Cummins’ (relatively) new X15 diesel or a number of Volvo Penta engines.
Electrek’s Take

Do any research at all into farming and agriculture as-a-whole and you’ll be shocked by the age of farmers and the age of their equipment, too. The industry is packed with combustion engines, people fearful of big corporations taking their data, and of big governments cutting off their fuel supplies (however ironic that may be). To them, and to the heavy machines that are already too big and heavy to work in rain and mud in some cases, a relatively lightweight, on-site energy solution might be a welcome thing.
