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.

OpenAI says Robinhood’s tokens aren’t equity in the company

OpenAI says Robinhood's tokens aren't equity in the company

OpenAI is distancing itself from Robinhood‘s latest crypto push after the trading platform began offering tokenized shares of OpenAI and SpaceX to users in Europe.

“These ‘OpenAI tokens’ are not OpenAI equity,” OpenAI wrote on X. “We did not partner with Robinhood, were not involved in this, and do not endorse it.”

The company said that “any transfer of OpenAI equity requires our approval — we did not approve any transfer,” and warned users to “please be careful.”

Robinhood announced the launch Monday from Cannes, France, as part of a broader product showcase focused on tokenized equities, staking, and a new blockchain infrastructure play. The company’s stock surged above $100 to hit a new all-time high following the news.

“These tokens give retail investors indirect exposure to private markets, opening up access, and are enabled by Robinhood’s ownership stake in a special purpose vehicle,” a Robinhood spokesperson said in response to the OpenAI post.

Robinhood offered 5 euros worth of OpenAI and SpaceX tokens to eligible EU users who signed up to trade stock tokens by July 7. The assets are issued under the EU’s looser investor restrictions via Robinhood’s crypto platform.

“This is about expanding access,” said Johann Kerbrat, Robinhood’s SVP and GM of crypto. “The goal with tokenization is to let anyone participate in this economy.”

The episode highlights the dynamic between crypto platforms seeking to democratize access to financial products and the companies whose names and equity are being represented on-chain

U.S. users cannot access these tokens due to regulatory restrictions.

BYD launches new discounts, offering +50% off smart driving tech

Despite the warnings, BYD continues introducing new discounts. On Wednesday, BYD’s luxury off-road brand began offering over 50% Huawei’s smart driving tech.

BYD introduces new discounts on smart driving tech

After BYD cut prices again in May, the China Automobile Manufacturers Association (CAMA) warned that the ultra-low prices are “triggering a new round of price war panic.”

Although they didn’t single out BYD, it was pretty obvious. BYD slashed prices across 22 of its vehicles by up to 34%, triggering several automakers to follow suit in China.

BYD’s cheapest EV, the Seagull, typically starts at about $10,000 (66,800 yuan). After the price cuts, the Seagull is listed at under $8,000 (55,800 yuan).

It doesn’t look like China’s EV leader plans to slow down anytime soon. Fang Cheng Bao, BYD’s luxury off-road brand, introduced new discounts on Huawei’s smart driving tech on Wednesday.

The limited-time offer cuts the price of Huawei’s Qiankun Intelligent Driving High-end Function Package to just 12,000 yuan ($1,700).

Buyers who order the smart driving tech in July will save over 50% compared to its typical price of 32,000 yuan ($4,500).

Earlier this year, Fang Chang Bao launched the Tai 3, its most affordable vehicle, starting at 139,800 yuan ($19,300). The Tai 3 is about the size of the Tesla Model Y, but costs about half as much.

The Tai 3 will spearhead a new sub-brand of electric SUVs following the more premium Bao 8 and Bao 5 hybrid SUVs.

BYD’s luxury off-road brand sold 18,903 vehicles last month, up 50% from May and 605% compared to last year. Fang Cheng Bao has now sold over 10,000 vehicles for three consecutive months.

The Chinese EV giant sold 382,585 vehicles in total in June, an increase of 12% from last year. In the first half of the year, BYD’s cumulative sales reached over 2.1 million, a YOY increase of 33%.
