14 Coradia iLint to start passenger service on first 100% hydrogen operated route

Posted by in categories: energy, transportation

Just 1 kilo of hydrogen fuel can do the same as around 9.9 pounds of diesel.

French-based company Alstom broke new ground in transportation. The company announced the world’s first hydrogen train, the Coradia iLint, reached Bremervörde, Lower Saxony, Germany.

This regional train only emits steam and condensed water while operating with a low noise level. With this breakthrough, it has been aimed to contribute to the greenest rail network globally, Alstom says.

GAMEOPT: An algorithm to optimize the flow of vehicles through dynamic unsignalized intersections

Posted by in categories: energy, information science, mathematics, transportation

Managing road intersections in crowded and dynamic environments, such as urban areas, can be highly challenging. The poor management of traffic at these can lead to road accidents, wastage of fuel, and environmental pollution.

Researchers at the University of Maryland have recently developed GAMEOPT, a that could help manage unsignalized road intersections with high traffic more efficiently. The research team with members, Nilesh Suriyarachchi, Rohan Chandra, John S. Baras and Dinesh Manocha introduced their method in a recent paper to be published in the proceedings of the 25th IEEE International Conference on Intelligent Transportation Systems (IEEE ITSC 2022). This method combines optimization techniques with ideas from game theory, a mathematical construct that represents situations in which different agents are competing with one another.

Forty percent of all crashes, 50% of serious collisions, and 20% of fatalities occur at unsignalized intersections,” Chandra, a member of the research team, told TechXplore. “Our primary objective is to improve traffic flow and in poorly regulated or unregulated traffic intersections. To achieve this objective, we propose an algorithm that combines ideas from optimization and game theory to understand how different traffic agents cooperate and negotiate with each other at traffic intersections.”

Trains that run on hydrogen.

Re-sharing.


(CNN) — The future of environmentally friendly travel might just be here — and it’s Germany that’s leading the charge, with the first ever rail line to be entirely run on hydrogen-powered trains, starting from Wednesday.

Faster fish tracking through the cloud

Posted by in categories: energy, internet, sustainability

The fastest way to track a fish is to use the cloud, figuratively speaking. A new acoustic receiver, developed by researchers at Pacific Northwest National Laboratory (PNNL) and published in the IEEE Internet of Things Journal, sends near-real-time fish tracking data to the digital cloud, providing timely information to dam operators and decision-makers about when, where, and how many fish are expected to pass through dams. Instead of relying on seasonal estimates of fish migration from previous years, these data from tagged fish support more informed decisions about dam operations that affect fish passage.

“This receiver provides up-to-the-hour data to dam operators to assist in making informed day-to-day decisions in support of passage, like adjusting water flow when it’s clear that a large group of juvenile fish are approaching the dam,” said Jayson Martinez, a PNNL mechanical engineer who co-developed the receiver.

Hydropower dams are an important source of dependable renewable energy, generating about six percent of total electricity in the United States. Helping fish navigate them safely is a key part of reducing dams’ environmental impact. The new receiver is a critical piece of the puzzle in the ongoing endeavor to improve fish passage.

Scientists to take ‘CAT scan’ of B.C. volcano to locate best geothermal energy spotsRed Deer Advocate

Posted by in categories: energy, sustainability

Scientists are planning a “CAT scan” of a British Columbia volcano to help harness the underground heat that turns rock into magma for renewable energy.

“Canadians are often surprised to know there’s volcanoes in the country,” said Steve Grasby, a geologist with Natural Resources Canada. “But there are active volcanoes.”

Grasby and his colleagues are headed about 24 kilometres west of Whistler, B.C., to Mount Cayley, part of the same mountain chain as well-known volcanic peaks such Mount St. Helens in Washington State.

Wireless tech measures soil moisture at multiple depths in real time

Posted by in categories: energy, food, space

Researchers from North Carolina State University have developed a wireless system that uses radio transmitters and receivers to estimate soil moisture in agricultural fields at multiple depths in real time, improving on existing technologies that can be used to inform irrigation practices that both improve crop yield and reduce water consumption.

“Estimating is important because it can be used by growers to irrigate their fields more efficiently—only irrigating fields when and where the water is needed,” says Usman Mahmood Khan, first author of a paper on the work and a Ph.D. student at NC State. “This both conserves and supports things like smart agriculture technologies, such as automated irrigation systems. What’s more, conserving water resources can also help reduce , because less energy is used to pump water through the irrigation system.”

The new technology, called Contactless Moisture Estimation (CoMEt), does not require any in-ground sensors. Instead, CoMEt assesses soil moisture using something called “phase,” which is a characteristic of radio waves that is affected by both the wavelength of the radio waves and the distance between the radio wave’s transmitter and the wave’s receiver.
