“That’s why reuse, purposing and recycling becomes important,” says Iryna Zenyuk, associate professor in chemical and biomolecular engineering at the University of California, Irvine. “Most EV manufacturers provide battery warranty of 8 years or more and about 100,000 miles of driving range.
Ride-hailing is not only for the young. An analysis of data from the 2017 National Household Travel Survey found that highly educated, affluent seniors in urban areas were among those who were more likely to be adopters of ride-hailing services. Often, these adults must give up their licenses, especially if they have a medical condition, said Suman Kumar Mitra, an assistant project scientist at the Institute of Transportation Studies at UC Irvine. … Safety is a concern for this population, too, he said. But he surmises that the benefits of the services outweigh the safety concerns.
One of the many ways modern societies lose valuable drinking water is through toilets. So says environmental engineer Stanley Grant of the University of California, Irvine. He and colleagues study ways to manage the water supply in urban areas. And given increasing drought due to global warming, the topic has never been more urgent.
“We must investigate this for every single pipe we put hydrogen into,” said Jack Brouwer, director of the advanced power and energy program at the University of California, Irvine, “but it’s a phenomenon we can manage because it’s slow.” Problem pipes and compressors could be replaced over the course of years, he said. Or pipes could be protected with coatings applied from the inside by robotic devices called pigs that are currently used for pipeline inspection and maintenance.
“In most cases, we do not know how much groundwater exists in storage,” write the authors of a study published last month in Water Resources Research (WRR), a journal of the American Geophysical Union. ... One-third of the world’s 37 largest aquifers are highly stressed to over-stressed, according to a companion study published in the same issue of WRR. ... Scientists at the University of California, Irvine led both studies, with doctoral student Alexandra Richey serving as lead author.
“Documenting what happened in Melbourne during the Millennium Drought was a real eye-opener,” said paper co-author Stanley Grant, a civil and environmental engineer at the University of California, Irvine. “It’s like looking into what the future could be for California if we got our act together.”
