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.

2D boundaries could create electricity

Posted by in categories: energy, materials

There’s still plenty of room at the bottom to generate piezoelectricity. Engineers at Rice University and their colleagues are showing the way.

A new study describes the discovery of piezoelectricity—the phenomenon by which mechanical energy turns into —across phase boundaries of two-dimensional materials.

The work led by Rice materials scientists Pulickel Ajayan and Hanyu Zhu and their colleagues at Rice’s George R. Brown School of Engineering, the University of Southern California, the University of Houston, Wright-Patterson Air Force Base Research Laboratory and Pennsylvania State University appears in Advanced Materials.

In a first, researchers produce oxygen from magnets for space exploration

Posted by in categories: energy, space

The new method could be the key to getting oxygen to Mars and beyond.

The study was conducted in a special drop tower facility that simulates microgravity conditions. The research proved magnets were effective at producing oxygen. The new method removes gas bubbles from liquids. Producing enough oxygen for astronauts in space is a complicated affair that is only set to become more difficult as we travel to Mars and beyond.

Now, researchers have invented a new way to make oxygen for astronauts using magnets, according to a University of Warwick statement.
