first_imgScience and Technology Caltech Water Conservation and the “New Normal” By SHAYNA CHABNER McKINNEY Published on Tuesday, June 9, 2015 | 5:12 pm Make a comment Business News Credit: Lance Hayashida/CaltechAt Caltech, as is true elsewhere in Pasadena and throughout California, water—and how to use it conservatively, conscientiously, and effectively—is a top priority.Governor Jerry Brown’s recent executive order to reduce water consumption and the Pasadena’s City Council’s subsequent regulations for limiting use have brought heightened attention to California’s drought. At Caltech, which has been working to reduce water consumption since long before the drought, water use is directly tied to research. Indeed, technical equipment and infrastructure can only operate safely and well when cooled. But here as elsewhere, the recent legislation has prompted renewed discussion about how to respond appropriately in the face of stricter conservation standards.On Tuesday, June 9, Caltech’s Sustainability Office is leading two campus town hall meetings and a water conservation resource fair to engage the community in a conversation about Caltech’s continuing water conservation efforts. The meetings will be held from 10–11:30 a.m. and 12–1:30 p.m. in the Beckman Institute Auditorium; the fair will take place in the Beckman Institute Courtyard from 11 a.m. to 2 p.m.To help us to better understand this issue, as well as Caltech’s approach to water conservation and overall sustainable practices, we recently sat down with John Onderdonk, the director of sustainability programs at Caltech. Onderdonk joined the Institute eight years ago to lead its sustainability efforts.What is Caltech’s current water challenge?The city and state have asked us to significantly cut back on water use. On June 1, the Pasadena City Council declared a local water emergency, establishing a 28 percent water conservation goal that should be reached between now and January 2016. That’s a very short timeline and a very significant water reduction.Annually, Caltech uses about 200 million gallons of water, and we have been fairly consistent in that use over the last couple years, with a steady decrease from our peak use in 2006. Our industrial plants—the central and satellite plants—use more than half of that water in the process of providing electricity, heating, and cooling to the buildings on campus. The remaining water consumption is distributed between irrigation at about 16 percent—or 32 million gallons—and domestic building use at about 34 percent—or 68 million gallons.The city and state’s conservation efforts are focused on making immediate reductions. The way we are able to work toward their reduction goals right away is through our irrigation and other visible conservation efforts—on top of what we have already done up to this point.Some of the ways in which we are currently working toward the conservation goal are:* Maintaining a two-days-per-week watering schedule* Draining all of the campus water features that are not used to support biological life or recreational activities. These include:– Millikan Reflecting Pool– Beckman Institute Gene Pool– Watson Laboratory fountain– Beckman Auditorium fountains– Beckman Institute Courtyard fountain– South Undergraduate Courtyard fountain– Linde + Robinson Perception fountain– Moore Laboratory fountain– And smaller water features outside Parsons Gates, Dabney Garden, and The AthenaeumWhat are some of the changes people might see or experience because of these cutbacks?We are definitely going to see a physical change in the look of campus. As we stick to two days of watering per week across campus, and as we progress into the high summer heat, grasses will start going golden. That will be one of the most noticeable changes.We are also already seeing a lot of the trees, particularly the redwood trees near Watson [Laboratory], that are drought stressed. In fact, we removed five redwoods this month because they had died.Our trees are irrigated with the sprinkler system in our grass, so as we reduce the amount of watering that we can do, they in turn get a lot less water. To change that, we would need to retrofit our irrigation system for the trees. That would be costly.We may have to take more trees down if they die and as they pose safety hazards and risks. To help minimize that impact as best we can, we are already doing some supplemental watering for the trees, and we are testing a pilot project with an atmospheric air condenser to see if we can generate water for the trees and plants in alternative but still cost-effective ways.What measures does Caltech already have in place to conserve water?Since 2006, the Institute has reduced total water use by about 40 percent as part of its overall sustainability plan and efforts. We have made some significant gains, a lot by making changes to our system and everyday operation that you can’t really see. That has included installing recirculating water systems in fountains and water features; installing low-flow fixtures in our buildings; plumbing our new buildings with purple pipes, which means that they are compatible with recycled water and could use recycled water in the future for flushing; and evaluating water-saving measures in the central and satellite plant cooling towers. One of the largest factors in this decrease is the energy-conservation efforts we have implemented across campus that have reduced the cooling load on the central plant.We have also done a lot of great things in our new buildings, and we are building them with the future in mind. Today, 10 percent of our buildings on campus are LEED certified, and all of those buildings are at least 30 percent more water efficient than the code requires. The newest building on campus, the modernized Gates–Thomas Laboratory, is 35 percent more water efficient than code requires. And the outdoor irrigation in Gates–Thomas is 50 percent more efficient than the code requires, in part, because we have it set up with a drip-only irrigation system.Also, we have a cistern in the Linde + Robinson Laboratory that catches rainwater and runoff.What are you hoping to achieve with the town hall?We certainly want to tackle our water conservation efforts holistically and strategically—that’s the Caltech way of doing it. It is going to take time because a lot of what we are looking at are engineering challenges with capital costs and requiring an investment of time.We will tackle these over the long term, but in the meantime, we also have to find a way to be compliant, be a good neighbor, and be tactical and meet the short-term guidelines and restrictions that the city has in place. I’m hoping that our community can rise to that challenge and that we can have a conversation about the issue, what we are doing, and what we might do to address this problem now and for the future.The current drought and the city’s water-reduction goals may be a short-term issue, but carrying out our work using less water is the new normal.For more information about Caltech water conservation and sustainability efforts, visit Caltech’s Sustainability Office website.

first_imgA skeleton of an extinct creature was found on the coast of Peru. Evolutionists are all calling it a walking whale.In Current Biology, a team led by Olivier Lambert announced a skeleton of what they call an “amphibious whale” or a “quadrupedal whale” they found off the coast of Peru. When the story (complete with artists’ conceptions) hit the press, reporters took the bait and ran with it without asking any questions, printing blow-ups of the artwork as the leading tease under their breathless headlines.Credit: Brett MillerAncient, four-legged whale with otter-like features found along the coast of Peru (Cell Press).Ancient Four-Legged Whale Swam Across Oceans, Walked Across Continents (Live Science).Amazing four-legged fossil shows how walking whales learned to swim (New Scientist).Fossil of ancient four-legged whale found in Peru (BBC News).Ancient four-legged whales once roamed land and sea  (The Conversation).The lead discoverer was ecstatic about the evolutionary implications of his discovery. “This is the first indisputable record of a quadrupedal whale skeleton for the whole Pacific Ocean, probably the oldest for the Americas, and the most complete outside India and Pakistan,” said Olivier Lambert of the Royal Belgian Institute of Natural Sciences.The team believes the date of the fossil fits the assumed evolutionary transition between artiodactyls and cetaceans, provided it was able to cross the ocean from Pakistan, where the other alleged ‘walking whale’ specimens were found. The discoverers embedded their interpretation into the name, calling it Peregocetus pacificus, “the traveling whale that reached the Pacific.”Comparative sizes of humpback whale and its presumed land ancestor. Credit: Illustra Media.Experience through many years of reporting overhyped claims by evolutionists teaches one to remain skeptical. First of all, the beast does not resemble a whale. It has a long snout, and probably a long tail, and some possible webbing in its four feet. But so do seals, sea lions, beavers, and otters. It is not really that different from the extinct animals in Pakistan that have long been touted as transitional forms, except that this one was found on the west coast of Peru. It may have been about four feet long, but whales are among the largest animals that ever lived.Since the news media are not doing their duty to ask questions, let’s do it for them.How do they know it is a whale? They don’t. That’s their interpretation. It would be like calling a platypus a duck because of its duckbill, or a snake because of its poison spur.How could it be a non-whale? Many other animals have some of these traits: webbed feet, long snouts, and an amphibious lifestyle. The authors say that the creature shared some traits with beavers and otters. Extinct animals often display a mosaic of traits.How is it unlike a whale? It is not an obligate marine mammal, where every function has to be performed in water 24 x 7. That’s a huge change in lifestyle, requiring many simultaneous adaptations.Is it really a transitional form? Many mammals with amphibious lifestyles are not considered transitional forms to whales: manatees, hippos, sea lions, beavers, otters, humans. Nobody watched how this animal lived, because it is extinct.Did it really cross the ocean? The authors claim that Africa and South America would have been closer when this animal lived. That proves nothing. It would still be a long, long way for a fish-eating amphibious mammal to travel that far. With only one specimen known, there’s too little evidence to make a case. Many types of animals are known to be cosmopolitan. Maybe this one was, too, but we lack enough fossils to know. You can’t build a story on one fossil. You can’t say it swam from Pakistan to Peru in order to evolve into a new creature on its way to whalehood.Why not believe it was a transitional form? In the Illustra Media documentary Living Waters, Dr Richard Sternberg points out irreducibly complex traits like the male reproductive system that would need relocation inside the body plus a complex cooling system to prevent sterility. That, and many other systems, would require complete overhauls for obligate marine living, involving numerous genetic changes. And yet the probability of getting just two coordinated mutations, he calculated, is 100 million years, far longer than the time allowed for alleged “whale evolution” to occur. This consideration alone blows the story out of the water, so to speak.Epistemic modesty should keep scientists from spinning elaborate yarns about great transformations in evolution. The whale story is one of the biggest. It’s sufficient to say that ‘We found another unknown animal in the fossil record, and here are its features.’ (Visited 557 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more
