Startups show off ocean-preserving tech at Paris trade fair

By Mona Guichard
Harnessing ocean currents to boost fuel efficiency of vessels, or tracking whales using sensor data and AI -- startups at Paris trade fair Vivatech have been showing off the latest innovations aimed at protecting the environment.
Recently developed AI programs capable of learning from vast datasets have boosted projects trying to understand and predict real-world phenomena, several company founders told AFP.
"We have to use AI because in the natural world there are too many variables" to deal with manually, said Emily Charry Tissier, a biologist and founder of Canadian startup Whale Seeker, which is developing technology to track sea mammals.
Powered by "neural network" systems that ape the functioning of the human brain, the learning systems behind today's AI models "can calculate a weather forecast 1,000 times faster than a standard digital model running on a supercomputer", agreed oceanographer Alexandre Stegner.
He flagged an AI model developed by his firm, Amphitrite, that he said could predict ocean currents by crunching "several layers of satellite data corresponding to different physical variables".
It can forecast currents up to 10 days in advance, he said, offering sea captains "a simple way to save fuel" by slightly changing course and using currents to gain a speed boost of up to four knots.
That could save operators money on fuel, reduce the carbon emissions from shipping, and avoid the classic solution of telling sea captains to reduce their speed.
Technologies like these were being shown off in the halls of Vivatech as the U.N. Ocean Conference (UNOC) drew to a close hundreds of kilometers to the south in French Mediterranean city Nice.
The conference has pushed a treaty to protect 60 percent of the world's oceans closer to becoming law, with 55 signatures -- just five shy of the number required for its enactment.
New technologies could be "a very good thing" for the oceans, said Andre Abreu, International Affairs Director at the Paris-based Tara Ocean Foundation.
But he warned that innovation should not be harnessed to allow more fish to be caught.
"That would mean shooting ourselves in the foot" on goals like preserving marine biodiversity, he said.
That ambiguity can be seen in technology from OceanEyes, a Japanese startup using AI analysis of satellite data to predict sea conditions.
The company hopes to cut the time fishing boats spend tracking down a catch.
"A big problem in Japan is the efficiency of the fishery operations. Many fishers spend a lot of time searching for fish in the water," said boss Yusuke Tanaka.
With less fuel burnt, operators will save money and greenhouse emissions can be slashed.
Anticipating concerns about overfishing, OceanEyes said it also aimed to help vessels comply with recently updated Japanese regulations that oblige fishers to "ensure sustainable use of marine resources".
Whale Seeker's Tissier said technology could be used in a considered way to find sustainable solutions.
"I'd like the market to recognize its own limits -- not the limits of what we can do, but what we should do," she told AFP.
That attitude pushed her to refuse to work with a company that wanted to use whale detection to identify nearby fish to catch.
But startups cannot grow without funding and, in the context of oceans, investments are likely to come from big firms keen to make a saving -- from fishing and ship management companies to haulage and logistics giants.
This could well limit their ability to stand on principle.
Stegner called for "regulations that would push the maritime sector to reduce carbon emissions".
But Charry Tissier said the initiative could come from business.
"Technology is developing so much faster than regulation... what I'd like is for big companies to decide for themselves to be responsible," she said.

Japan's Mitsubishi Corp. bets big on US solar with $3.9bn expansion plan

TOKYO -- Japanese trading house Mitsubishi Corp. will boost its solar power generation capacity in the U.S. by 160% by 2028, Nikkei has learned, with the total project expenses expected to be around $3.9 billion. The company aims to localize more of its supply chain, taking advantage of favorable conditions for solar development in the U.S. Soaring global electricity demand, driven by a data center boom, has intensified the race to build out power infrastructure. Solar remains a relatively cost-effective option compared to offshore wind or nuclear, and the geographic scale of the U.S. provides abundant development opportunities.

Annual Economic Losses from Workers' Health Issues Reach 7.6 T. Yen

Tokyo, June 20 (Jiji Press)--Economic losses in Japan stemming from workers' mental or physical disorders, including shoulder stiffness and sleeplessness, total around 7.6 trillion yen each year, a study by Japanese researchers has shown. The losses, linked to lower labor productivity, represent about 1 pct of the country's nominal gross domestic product for 2024. The World Health Organization describes "presenteeism" as a condition where work efficiency declines due to mental or physical disorders, despite employees being present at work. It is often difficult to recognize such a condition as a loss for companies or society because the workers in question appear to be performing their jobs. In 2022, Koji Hara, associate professor at Yokohama City University, and other researchers conducted an internet survey of about 27,000 workers in Japan to assess symptoms related to mental and other health issues. As a result, the study estimated that annual losses from presenteeism and related factors amount to 7.6 trillion yen. Among men, the estimated losses were the highest for those aged 45-49, an age group that has a large working population and high average income. For women, the highest losses were estimated for those aged 25-29. [Copyright The Jiji Press, Ltd.]
