Pioneering ‘WindWings’ technology could make cargo ships greener

Pyxis Ocean sets sail with ground-breaking wind technology.

With the shipping industry estimated to be responsible for about 2.1% of global carbon dioxide emissions, the hunt is on for greener technology to reduce those numbers.

Eyeing a possible solution in what could prove to be a pivotal moment for the industry, shipping firm Cargill has retrofitted a cargo ship with enormous, rigid “WindWings” sails designed to slash fuel consumption.

The Pyxis Ocean vessel is now on its maiden voyage from China to Brazil to put the technology through its paces ahead of a possible rollout for the commercial shipping industry. The journey is expected to take around six weeks.

The 123-foot-tall sails are made from the same material used for wind turbines for maximum durability, folding down when the ship is in port and opening up when it’s out on the open sea.

The technology is the creation of British firm BAR Technologies. Its CEO, John Cooper, said that Cargill got in touch and asked if it could invent a wind propulsion system for its ships. “They arguably know more about shipping than BAR Tech; we’re the techie guys knowing how to invent things and that partnership has been really, really strong.”

Using wind power rather than engine power could reduce a ship’s emissions by 30% over its lifetime, according to Cargill.

“The maritime industry is on a journey to decarbonize; it’s not an easy one, but it is an exciting one,” said Cargill president Jan Dieleman. “At Cargill we have a responsibility to pioneer decarbonizing solutions across all our supply chains to meet our customers’ needs and the needs of the planet.”

The WindWings project is co-funded by the European Union as part of the CHEK Horizon 2020 initiative and offers a retrofit solution to decarbonize existing vessels.

The performance of the WindWings on the Pyxis Ocean will be carefully monitored during its voyage, with the gathered data helping engineers refine the design, operation, and performance of the sails before potentially bringing the technology to other cargo ships across the industry.

AMD’s new Ryzen AI 300 chips look like the real deal
AMD's CEO delivering the Computex 2024 presentation.

The pressure is on at Computex this year. With the May announcement of Copilot+ PCs and Microsoft's deep partnership with Qualcomm, the stakes were high for AMD coming into the show. But the company certainly didn't show up empty-handed.

Its announcements have all centered around Zen 5, the company's latest architecture, both on desktop and mobile. But at the moment, these mobile chips feels especially noteworthy in light of Copilot+. AMD calls it the Ryzen AI 300 series. It's a complete rebrand for AMD, not unlike Intel's move to "Core Ultra" in its most recent generation. But this time, it's all about AI.

It’s the end of an era for Samsung smartwatches
Galaxy Watch 4 Classic (left) and the Galaxy Watch 3 (right)

For the longest time, Samsung smartwatches have run on Tizen, starting with the Samsung Gear 2 in 2014. Since then, every Samsung smartwatch up until the Galaxy Watch 4 has run on Tizen. With the Galaxy Watch 4, Samsung joined the rest of the Android smartwatch industry by adopting Wear OS. Now, after a decade of having released its first Tizen smartwatch, Samsung is getting ready to sunset Galaxy Store support for Tizen smartwatches in 2025.

According to the translated screenshot posted by Reddit user Seaweed_Maximus, the Galaxy Store will stop selling paid Tizen watch content by September 30, 2024, and will stop allowing new downloads of free Tizen watch content by May 31, 2025. Services related to the watch will stop everywhere except in the My Apps section of the Galaxy Store. On September 30, 2025, downloads of existing purchased items on the My Apps page will end.

The RTX 5080 may be a disappointing upgrade after all
PNY RTX 4080 with the power connector attached.

Although Nvidia hasn't said much about its upcoming RTX 50-series graphics cards during Computex, they're coming, and we just got a new rumor about their potential specs. According to a reputable leaker, the RTX 5080 might be less impressive than initially suggested. If this is proven true, is this the direct result of Nvidia not needing to try as hard, given that AMD may be sitting out the race for the best graphics card in this generation?

The intel comes from kopite7kimi -- a frequent leaker in the GPU space, who has now said that not only will it take a while for most of the lineup to arrive but also that the GB203 GPU will be significantly cut down compared to previous rumors. Many suspect that the GB203 will be the GPU inside the RTX 5080, so this is a rather big deal.
