📌 MAROKO133 Eksklusif ai: Electric hydrofoil ferry completes record 160-mile voyag

The world’s longest electric sea journey by a passenger vessel has been completed, signaling a shift in how electric ferries could operate in the future.

Sweden-based Candela says its electric hydrofoiling ferry, the P-12, has successfully traveled 160 nautical miles from Gothenburg to Oslo, proving that electric vessels are no longer limited to short, fixed routes or specialized charging infrastructure.

Electric ferries are expanding rapidly, particularly in Norway, where more than 100 are already in operation.

But most remain constrained by high energy consumption and short ranges, forcing operators to rely on fixed routes and costly battery-swapping systems.

These limitations have slowed wider adoption despite strong policy support for electrification.

Candela set out to challenge that model by demonstrating how hydrofoil technology could dramatically reduce energy use.

The P-12 is the world’s first serial-production electric hydrofoil ferry, designed to lift its hull above the water using computer-controlled submerged wings. Once airborne, drag drops sharply, cutting energy consumption by about 80 percent compared with conventional vessels.

The 160-nautical-mile journey from Sweden’s west coast to Norway’s capital is the longest ever completed by an electric passenger ship.

The voyage was carried out over three days, with planned charging and demonstration stops along the route.

Hydrofoils change the math

At cruising speeds above 20 knots, the P-12 flies above the water, allowing it to operate at higher speeds while consuming far less power.

The ferry has a service speed of 25 knots and has exceeded 30 knots during trials, making it the fastest electric passenger vessel currently in operation. On a single charge, it can travel up to 40 nautical miles at cruising speed.

The vessel has already been deployed in Stockholm’s public transport system, where it operates alongside conventional ferries. But the Oslo journey highlighted an even bigger advantage: flexibility.

Unlike traditional electric ferries that depend on large battery containers swapped at fixed terminals, the P-12 can recharge using standard DC fast chargers.

During the voyage, the ferry used Sweden’s existing DC fast-charging network, including Aqua SuperPower stations.

Where fixed chargers were unavailable, the crew relied on a portable 360 kW DC charger connected to a mobile battery system towed by a Ford F-150 Lightning electric pickup.

“Charging infrastructure is the hidden cost of electrifying conventional vessels,” said Gabriele De Mattia, project engineer at Candela and lead engineer for the voyage.

“In many cases, building megawatt-scale chargers can cost as much as the vessels themselves. The breakthrough with P-12 is that it is fast to charge and extremely flexible in where it can operate.”

Infrastructure costs under pressure

The contrast became especially clear upon arrival in Oslo. The city’s fastest conventional electric ferry operates a fixed 10-nautical-mile route and depends on swapping multi-megawatt-hour battery containers.

That system alone has cost hundreds of millions of Norwegian kroner and has faced delays and cost overruns, limiting expansion to new routes.

By comparison, Candela says the total electricity cost for the P-12’s record-setting journey was just over 200 euros.

The result has renewed interest in whether hydrofoiling electric vessels could offer a more scalable and cost-effective path for electrifying passenger transport at sea.

📌 MAROKO133 Breaking ai: There’s Something Fascinating Hiding Under Jupiter’s Clou

The enormous storms of impenetrable clouds covering Jupiter’s surface make it nearly impossible for us to get a glimpse of what lies below. Any spacecraft attempting to get a closer look would be vaporized, melted, or crushed if it attempted to sail through. NASA’s Galileo spacecraft, for instance, went dark almost immediately when it intentionally plunged into Jupiter’s atmosphere back in 2003.

While Jupiter — a giant ball of swirling gases and liquids — isn’t believed to have a true surface, scientists have been trying to get a better sense of its layers. Now, using data from NASA’s Juno and Galileo missions, a team of scientists at the space agency’s Jet Propulsion Laboratory and the University of Chicago have created a highly detailed computational model of Jupiter’s atmosphere.

And as detailed in a new paper, published in The Planetary Science Journal last month, they found something surprising down there: Jupiter appears to contain one-and-a-half times as much oxygen as the Sun — far more than previous estimates, which suggested it was only a third as much oxygen.

The findings also support the prevailing theory that Jupiter formed by accreting icy material billions of years ago near or past the “frost line,” as Space.com points out, meaning the distance from the Sun where temperatures are low enough for ammonia, methane, and water ice to form. (Whether the planet formed in its current orbit or much further away from the Sun before migrating to its current position over billions of years remains a topic of debate.)

Much of the oxygen is tied up in water as well, which changes its behavior drastically depending on temperature, further complicating our efforts to map out Jupiter’s layers.

The researchers’ computational model takes into account both the chemical reactions taking place — from extremely hot metal molecules deep inside the core and much cooler regions in its atmosphere — and the movement of gases, clouds and droplets.

“You need both,” said lead author and UChicago postdoctoral researcher Jeehyun Yang in a statement. “Chemistry is important but doesn’t include water droplets or cloud behavior. Hydrodynamics alone simplifies the chemistry too much. So, it’s important to bring them together.”

Their model suggests that gases move far more slowly through Jupiter’s atmosphere than previously thought.

“Our model suggests the diffusion would have to be 35 to 40 times slower compared to what the standard assumption has been,” Yang explained. “Instead of moving through an atmospheric layer in hours, a single molecule might take several weeks.”

It’s only one small part of a much larger mystery surrounding our solar system’s largest planet — and its more-than-intriguing collection of moons. The angry gas giant of swirling gases continues to baffle even top scientists.

“It really shows how much we still have to learn about planets, even in our own solar system,” Yang said.
