Wind-powered Dutch ship sets sail for greener future

The world’s first chemical tanker ship fitted with massive rigid aluminium “sails” has left Rotterdam, its owner hoping to plot a route to bringing down the shipping industry’s huge carbon footprint.

The MT Chemical Challenger, a 16,000-tonne chemicals transporter set sail from Antwerp for Istanbul on Friday, and will undergo sea trials along the way.

Built in Japan and kitted out with four giant 16-metre-high (52 foot, 6 inch) sails similar to aircraft wings, the tanker’s owners hope to cut fuel consumption by 10 to 20 percent as the sails will allow the ship’s captain to throttle back on the engine.

“As an avid sailor myself, I have been thinking for a long time how we can make our industry more sustainable,” said Niels Grotz, chief executive of Chemship, which operates a fleet of chemical tanker vessels mainly between US ports in the Gulf of Mexico and the eastern Mediterranean.

“Today we launch our first wind-assisted chemical tanker, which we hope will serve as an example to the rest of the world,” Grotz told AFP at the ship’s unveiling.

Global shipping — which burns diesel and other bunker fuels — contributed around 2.0 percent of the world’s carbon emissions in 2022, the International Energy Agency said.

New guidelines by the International Maritime Organisation said shipping emissions needed to be cut by at least 40 percent by 2030 and down to zero by around 2050 if the Paris Climate Accords are to be achieved.

“Shipping has always been extremely competitive and it will be a struggle to reach these targets,” admitted Grotz, who added the company was unlikely to “make money” on its latest project.

“But we have to bring down CO2 emissions — and we decided we’re not just going to sit and wait for something magical to happen.”

“With the sails on this ship we’re expecting a yearly reduction of some 850 tonnes. That’s the same output as around 500 cars annually,” Chemship added in a statement.

Pulling power

Grotz said the project to put sails on one of his chemical tankers — with others to follow — came when he and Dutch company Econowind, which specialises in building wind propulsion systems for ships, first put their heads together three years ago.

Last week the installation of the four sails was completed while the Chemical Challenger lay dockside in Rotterdam’s massive sprawling harbour.

Although not the first modern ship to be kitted out with rigid sails — last year British firm Cargill put a wind-assisted cargo ship to sea for instance — Chemship said their Chemical Challenger is the world’s first chemical tanker ship with sails.

Built similar to an aeroplane wing, the rigid aluminium sails are equipped with a system of vents and holes to maximise airflow in winds of up to 61 kilometres (33 knots, 38 miles).

“This system called a ‘ventilated wingsail’ increases the wind’s power by five times — and gives the same power as an imaginary sail of around 30 by 30 metres,” said Rens Groot, sales manager at Econowind.

‘Modern day sailors’

Groot told AFP the installation of modern-day rigid sails on massive ships harked back to a time when sailing was the only way to move across the oceans.

Sails on ships are also reopening long-forgotten routes that fell out of favour as steam and fuel replaced wind power.

“Once again, modern-day ‘sailors’ will have to look for the wind, for instance along the Brouwer route,” Groot said, referring to a sailing route around the Cape of Good Hope, first pioneered by Dutch explorer Hendrik Brouwer around 1611.

That route dips into the so-called “Roaring Forties” across the Indian Ocean before snaking north again along the Australian west coast to Asia.

It became compulsory a few years later for captains employed by the Dutch East India company on their way to the Netherlands’ colonies in today’s Indonesia.

“We are trying to find a way to bring nature back into technology,” said Groot. “Suddenly, you can feel a ship sailing again — just like in the olden days,” Groot said.

Don't worry if your Android gets stolen, new Theft Detection Lock comes to rescue

Google revealed plans to introduce a ground-breaking security feature for Android devices: Theft Detection Lock at the Google I/O 2024 developer conference held on Wednesday.

This innovative addition is specifically designed to combat the rising threat of smartphone theft by automatically locking the device when suspicious activity is detected.

Powered by artificial intelligence, Theft Detection Lock utilizes advanced algorithms to identify common motions associated with theft.

For instance, if a device suddenly begins moving rapidly in the opposite direction, indicative of a potential theft scenario, the feature swiftly triggers a screen lock mechanism.

This proactive measure aims to thwart thieves from easily accessing sensitive user data stored on the device.

In addition to Theft Detection Lock, Google also announced the introduction of an Offline Device Lock feature. This functionality serves as a safeguard against intentional disconnection from the network, a common tactic employed by thieves to bypass security measures.

Instances such as repeated failed authentication attempts will prompt the Offline Device Lock, providing an added layer of protection for users’ devices.

Google revealed plans to enhance device security with measures aimed at preventing remote factory resets initiated by thieves.

Under the forthcoming update, if a thief attempts to reset a stolen device, they will be unable to set it up again without the necessary device or Google account credentials. This strategic move renders stolen devices essentially unsellable, significantly diminishing the incentives for phone theft.

Tesla must face vehicle owners' lawsuit over self-driving claims

A U.S. judge on Wednesday rejected Tesla’s bid to dismiss a lawsuit accusing Elon Musk’s electric car company of misleading owners into believing that their vehicles could soon have self-driving capabilities.

The proposed nationwide class action accused Tesla and Musk of having since 2016 falsely advertised Autopilot and other self-driving technology as functional or “just around the corner,” inducing drivers to pay more for their vehicles. 

U.S. District Judge Rita Lin in San Francisco said owners could pursue negligence and fraud-based claims, to the extent they relied on Tesla’s representations regarding vehicles’ hardware and ability to drive coast-to-coast across the U.S.

Without ruling on the merits, Lin said that “if Tesla meant to convey that its hardware was sufficient to reach high or full automation, the plainly alleges sufficient falsity.”

The judge dismissed some other claims.

Tesla and its lawyers did not immediately respond to requests for comment. Lawyers for Tesla vehicle owners did not immediately respond to similar requests.

The case was led by Thomas LoSavio, a retired California lawyer who said he paid an $8,000 premium in 2017 for Full Self-Driving capabilities on a Tesla Model S, believing it would make driving safer if his reflexes deteriorated as he aged.

LoSavio said he was still waiting for the technology six years later, with Tesla remaining unable “even remotely” to produce a fully self-driving car.

The lawsuit seeks unspecified damages for people who since 2016 bought or leased Tesla vehicles with Autopilot, Enhanced Autopilot and Full Self-Driving features.

Tesla has for many years faced federal probes into whether its self-driving technology might have contributed to fatal crashes.

Federal prosecutors are separately examining whether Tesla committed securities fraud or wire fraud by misleading investors about its vehicles’ self-driving capabilities, according to three people familiar with the matter.

Tesla has said Autopilot lets vehicles steer, accelerate and brake in their lanes, and Full Self-Driving lets vehicles obey traffic signals and change lanes.

But it had acknowledged that neither technology makes vehicles autonomous, or excuses drivers from paying attention to the roads.

The case is In re Tesla Advanced Driver Assistance Systems Litigation, U.S. District Court, Northern District of California, No. 22-05240.

Microsoft asks hundreds of China staff to relocate

Microsoft is asking about 700 to 800 people in its China-based cloud-computing and artificial-intelligence operations to consider transferring outside the country, the Wall Street Journal reported on Thursday.

The employees, mostly engineers with Chinese nationality, were earlier in the week offered an option to transfer to countries including the U.S., Ireland, Australia and New Zealand, the report said, citing people familiar with the matter.

The move comes amid spiralling US-China relations as the Biden administration cracks down on various sectors of Chinese imports, including electric vehicle (EV) batteries, computer chips and medical products.

A Microsoft spokesperson told the Journal that providing internal opportunities is part of its global business and confirmed the company had shared an optional internal transfer opportunity with a subset of employees.

Reuters reported earlier this month that the U.S. Commerce Department is considering a new regulatory push to restrict the export of proprietary or closed source AI models, whose software and the data it is trained on are kept under wraps.

The spokesperson, however, told the newspaper that the company remains committed to the region and will continue to operate in China.

Microsoft didn’t immediately respond to a Reuters request for comment.
