The Energy Observer boat can run for 6 years on nothing but wind, solar, and hydrogen

Nobody could accuse Jérôme Delafosse of not having an adventurous spirit.

A professional diver and documentary maker, Delafosse is one half — with offshore racer and Merchant navy officer Victorien Erussard — of an ambitious duo who are setting off this month on an ambitious six-year quest, aboard one of the world’s most futuristic boats.

“The Energy Observer boat creates energy onboard,” Delafosse told Digital Trends. “It has solar panels, wind turbines, a kite that converts the engines into hydro generators, and a hydrogen fuel system that uses decarbonized sea water.”

The converted, 100-foot multi-hull race boat will sail around the world, serving as a symbol of the power of renewable energy. By combining different sustainable energy sources, the Energy Observer is completely autonomous — while still being able to plot its own course and sail against the wind

In all, the vessel will make exactly 101 stopovers in 50 countries around the globe, ranging from Cuba to Goa — and everywhere in between. The Energy Observer will start by crossing the Mediterranean, before traversing the Atlantic and Pacific oceans.

With a running cost of $4 million per year, it’s not going to be a cheap voyage, but Delafosse is confident the team will be able to able to cover the costs, although they’ve still got capacity for more financial partners.

Once the mission is over, Delafosse said that the Energy Observer boat could be rented out to people looking for a unique sailing opportunity. However, he hopes that the epic voyage will help do something a lot bigger than just advertise the boat itself.

“This isn’t only the first boat of its kind, but also an example of how these sustainable technologies could be used in houses, hotels and other applications on land,” Delafosse said. “Because we’re trying out all of this technologies, it’s like a floating laboratory [for the CEA-Liten research center in France.] We don’t just have the adventure of sailing, but also of testing these technologies in extreme conditions. That’s totally unique.”

Google has been finding more ways to make Gemini a part of your daily routine, from putting together playlists to ordering groceries through your favorite apps. Now it's expanding those capabilities to more services, with Google Search joining in, too.

The company has announced a new Connected Apps Platform that makes it easier for developers to bring their services to both Gemini and Search. Alongside this, Google is adding new partners to its growing lineup, bringing more of the apps people already use into its AI ecosystem.

AI bots are now trying to sabotage public health policies, like banning disposable vapes
Thousands of AI bots voted in a public health poll to block sales restriction on disposable vapes. It's like Big Tobacco is back from the dead.

In the broad context of AI and its perceived harms, health and medical risks often pop up in the conversation. The warnings even come from frontier AI labs, such as ChatGPT-maker OpenAI and Anthropic, both of which have warned about misusing AI to cook up bioweapons. Security experts have already spotted a few such incidents in the wild, especially with the usage of AI models without any solid guardrails. 

Well, it appears that the risks run deeper. As per an analysis appearing in the British Medical Journal (BMJ), AI bots are now being deployed to influence public policies governing health risks to citizens. In this instance, an attempt was made using AI bots to thwart regulations that aim to restrict the sale of disposable vapes, all while disguising the manipulation efforts as a response from real humans.

A tiny smartphone gadget can detect some of the nastiest chemicals in your water
Scientists built a tiny smartphone gadget that can spot toxic 'forever chemicals'
Smartphone-connected drinking water safety sensor Featured

What if checking your drinking water for dangerous chemicals were as simple as plugging a tiny gadget into your smartphone? Researchers in Japan have developed a compact sensor that could make that possible, potentially bringing sophisticated water contamination testing out of expensive laboratories and into people's hands.

Scientists at the Okinawa Institute of Science and Technology (OIST) have created a portable device capable of detecting extremely low concentrations of PFAS, commonly known as "forever chemicals." The findings were published in the journal Biosensors and Bioelectronics, which demonstrate how an inexpensive sensor and a smartphone could make identifying potentially harmful chemicals in water a lot easier.
