Researchers develop model to accurately predict vessel turnaround time at ports
In the 21st century, as global trade expands and cargo volumes surge, ports face mounting pressure to operate efficiently. A key challenge lies in accurately predicting vessel turnaround time (VTT)—the period between a ship's arrival and departure—which directly influences scheduling, congestion management, and energy use....

Fuel made from just air, power and water is taking off, but several things are holding it back
Imagine powering long-haul aircraft and heavy ships with fuels derived from just air, water and renewable electricity. This is moving from science fiction to the verge of reality, thanks to the falling price of renewables like wind and solar.... Read more

New AI language-vision models transform traffic video analysis to improve road safety
New York City's thousands of traffic cameras capture endless hours of footage each day, but analyzing that video to identify safety problems and implement improvements typically requires resources that most transportation agencies don't have.... Read more

New ship power system keeps vessels running even if central control fails
The shipbuilding industry is on the verge of a major leap forward. Timo Alho's doctoral dissertation at the University of Vaasa introduces a pioneering power management strategy that prevents ship blackouts. In Alho's management principle, the vessel's electrical equipment is capable of independently supporting the ship's grid without centralized commands.... Read more

Seismic data can identify aircraft by type
Instruments typically used to detect the ground motion of earthquakes can also be used to identify the type of aircraft flying far overhead, research by University of Alaska Fairbanks scientists shows. That's because aircraft sound waves also shake the ground, though to a much lesser extent.... Read more

Turbocharging hydrogen-fueled internal combustion engine
Southwest Research Institute (SwRI) has upgraded its hydrogen-powered heavy-duty internal combustion engine (H2-ICE) with a state-of-the-art turbocharger. The upgrades have significantly improved performance across the board, making the engine competitive with current long-haul diesel engines focused on fuel economy while maintaining near-zero tailpipe emissions....

Plane and car crash testing is still designed to keep men safe—that puts women in danger
The next time you board a commercial flight and are told how to sit in the brace position for an emergency landing, consider this: did you know that international plane safety testing only requires adult male crash test dummies?... Read more

Cheaper cars emit more pollution, creating urban air quality inequality
More expensive cars emit lower levels of pollution—meaning that motorists owning cheaper, higher-emitting vehicles contribute disproportionately to their local urban air quality problems, a new study reveals.... Read more

The next frontier in clean flight? Jet fuel from city waste
Aviation currently contributes about 2.5% of total global carbon emissions, and with air travel demand expected to double by 2040, cutting those emissions has become a pressing priority. One path forward is sustainable aviation fuel, a low-carbon alternative made from feedstocks such as used cooking oil and crops. But despite... Read more

Sulfur-based batteries could offer electric vehicles a greener, longer-range option
Picture an electric car that could go 600, 700 or even 1,000 miles on a single charge. That's much farther than the longest-range electric vehicles on the U.S. market, according to Car and Driver magazine—and twice as far the official rating for the long-range, rear-wheel-drive Tesla Model 3, which has...
