Pac-12: Buffs Survive, Advance By Their Magic Number – 59
Mar 14th
By B.G. Brooks, CUBuffs.com Contributing Editor
LAS VEGAS – If you’re thinking the Colorado Buffaloes are stuck on 59, you might be onto something. But here in Sin City, where gambling is the big engine that could, that’s a long way from crapping out.
It’s a magnificent number, a winning number, for Tad Boyle and his revitalized crew.
The Buffs’ last three wins – against Stanford in the next-to-last regular-season game, against USC in the first round of the Pac-12 Tournament, against California in the quarterfinals – have been by the same score: 59-56.
The Buffs’ two wins here have ended in identical, nail-biting, fist-gnawing fashion: CU is up by three in the closing seconds and survives a 3-pointer to tie at the buzzer.
In racehorse college basketball, 59 points are not a lot. Boyle’s guys love to run and score, but that’s not how this team – this season – has evolved after Spencer Dinwiddie’s knee injury in mid-January. In their last seven games, the Buffs haven’t hit 70 points, with 65 in a one-point overtime loss at Cal the high mark.
That’s the longest low-scoring stretch in Boyle’s about-to-be-completed four seasons in Boulder. But here’s the more telling bottom line number: Boyle’s fourth CU team has won 23 games (10 losses), making this season the second-most productive in terms of wins in school history. (His first two Buffs teams finished with 24 wins.)
And turning to something more topical since it’s the month of madness, those 23 wins should remove any mystery – if there was any – that might have shrouded CU’s inclusion in the NCAA Tournament field. Selection Sunday looms for the official word, but the word will be good. Book it.
But Friday finds the Buffs with things other than the NCAA Tournament on their minds. They have a semifinal date at 7:06 p.m. MDT with top-seeded and fourth-ranked Arizona in the MGM Garden Arena. Upsetting the Wildcats, then winning the Pac-12 championship on Saturday would remove all Selection Sunday mystery about the Buffs’ NCAA future; the tournament champ is in automatically.
Accomplishing that begins with beating powerful Arizona, whose players defend like they were guarding loved ones from a home invasion.
“They took a lot of pride in guarding us . . . we got punched in the mouth by a really good basketball team and we saw Arizona, I think, at their finest,” Utah coach Larry Krystkowiak said Thursday after Arizona had clamped down on his team in a 71-39 quarterfinal win. The halftime score: 34-13. Utah’s Big Three – Jordan Loveridge, Brandon Taylor and Delon Wright – were a combined 1-of-16 from the field.
The Buffs know something about the Wildcats’ defense from their regular-season meetings. Arizona won 69-57 in Tucson, 88-61 in Boulder. The Wildcats give up points as willingly as the IRS gives away cash; they lead the Pac-12 in scoring defense, allowing 58.7 points a game.
That’s very close to CU’s magic number of late – 59 . . . Hmmmmm.
“They’re the best defensive team in our league,” Boyle said. “It’s not even close. They’re the best rebounding team in our league. It is close there.”
That’s because CU is at 37.9 boards a game, while Arizona is at 38.9.
In their two wins over the Buffs this season, the Wildcats leaped to large early leads – as they did against the Utes Thursday. CU fell behind 18-4 in Tucson and 22-5 in Boulder in what would end in the Buffs’ worst home loss of the Boyle era.
Whether it makes a difference or not Friday, this is a different CU team, a more focused team. Eli Stalzer, who stepped to the foul line Thursday in the final 6 six seconds and hit one of two critical free throws, said the Buffs have learned something about themselves and the high energy Boyle wants from them since a March 1 loss (75-64) at Utah.
“Now it seems like guys don’t think they can take plays off; every possession is important,” Stalzer said. “We’re all working hard to do our best.”
That’s partially attributable to the transformation of junior guard Askia Booker, who has averaged 16.3 points, 5.7 rebounds and 3 assists. He’s shooting 46.7 percent from the field (21-of-45). In the two Pac-12 Tournament games, he has averaged 19 points a game, 5 rebounds and 3.5 assists. He’s hit 50 percent from the field (16-of-32).
Maybe more important than the numbers, Booker’s composure has stood out. He’s become CU’s glue, if you will, which at one point in his career might have seemed improbable if not impossible.
Boyle said, as a coach, “you hope” a player develops like Booker has: “He’s had an interesting career; he’s grown up exponentially – especially since Spencer went down. He was thrown in the fire of a leadership role . . . he’s done a great job. And that’s what’s so gratifying about doing this job. You see young men come in, where they are as freshman not just physically and skill-wise but emotionally, spiritually and maturity-wise. He’s come a long way.”
So have the Buffs. Boyle’s second CU team (2011-12) won the inaugural Pac-12 Tournament in Los Angeles with a four-day, four-game run as a No. 6 seed. His fourth team, as a No. 5 seed, is within two wins of a repeat. Boyle doesn’t have near the veteran leadership on this team that was apparent in L.A., but he’s seen a similar trait develop over the last several weeks. That would ownership.
“You look at that team with Nate (Tomlinson), Carlin (Brown) and Austin (Dufault) – they took ownership down the stretch and made it happen,” he said. “Now, we had to win some close games there . . . but now we have to play one of the best teams in the country in the semis and we didn’t have to do that two years ago.”
I asked Boyle if his players would have any difficulty in blotting out those two regular-season losses to the Wildcats, particularly the one in Boulder that concluded ESPN’s College GameDay visit.
“I don’t know, we’ll see,” Boyle answered. “That’s a distant memory. It’s a new day, a new opportunity. The way our guys are playing right now and feeling about themselves, they want that opportunity, they relish it. We’re not going to play with a lack of confidence (Friday).”
Palm oil production a source of heat-trapping methane

Methane leaks from palm oil wastewater
are a climate concern, CU-Boulder study says
are a climate concern, CU-Boulder study says
In recent years, palm oil production has come under fire from environmentalists concerned about the deforestation of land in the tropics to make way for new palm plantations. Now there is a new reason to be concerned about palm oil’s environmental impact, according to researchers at the University of Colorado Boulder.
An analysis published Feb. 26 in the journal Nature Climate Change shows that the wastewater produced during the processing of palm oil is a significant source of heat-trapping methane in the atmosphere. But the researchers also present a possible solution: capturing the methane and using it as a renewable energy source.
The methane bubbling up from a single palm oil wastewater lagoon during a year is roughly equivalent to the emissions from 22,000 passenger vehicles in the United States, the analysis found. This year, global methane emissions from palm oil wastewater are expected to equal 30 percent of all fossil fuel emissions from Indonesia, where widespread deforestation for palm oil production has endangered orangutans.
The methane bubbling up from a single palm oil wastewater lagoon during a year is roughly equivalent to the emissions from 22,000 passenger vehicles in the United States, the analysis found.
“This is a largely overlooked dimension of palm oil’s environmental problems,” said lead author Philip Taylor, a postdoctoral researcher at CU-Boulder’s Institute of Arctic and Alpine Research (INSTAAR). “The industry has become a poster child for agriculture’s downsides, but capturing wastewater methane leaks for energy would be a step in the right direction.”
The global demand for palm oil has spiked in recent years as processed food manufacturers have sought an alternative to trans fats.
For now, the carbon footprint of cutting down forests to make way for palm plantations dwarfs the greenhouse gases coming from the wastewater lagoons. But while deforestation is expected to slow as the focus shifts to more intensive agriculture on existing plantations, the emissions from wastewater lagoons will continue unabated as long as palm oil is produced, the researchers said.
However, the climate impact of the leaking methane could be mitigated by capturing the gas and using it to fuel power plants. Biogas technology has been used successfully for decades and it can produce renewable electricity at a cost that’s competitive with traditional fuels, the authors said.
The amount of methane biogas that went uncollected from palm oil wastewater lagoons last year alone could have met a quarter of Malaysia’s electricity needs. Tapping into that unused fuel supply could yield both financial and environmental benefits, the authors said.
Capturing methane at wastewater lagoons could be encouraged by making it a requirement before palm oil products can be certified as sustainable, the authors said. Current sustainability certifications do not address wastewater emissions.
Taylor, whose research typically focuses on carbon cycling in old-growth tropical forests, was inspired to do the analysis by undergraduate researcher Hana Fancher, who also is a co-author of the journal article. Fancher and Taylor were doing research in Costa Rica, where palm oil production is spreading, when Fancher became curious about how the oil was being processed.
“She has a wastewater background,” Taylor said. “She ended up doing an honors thesis on palm oil agriculture and wastewater emissions. This paper is an extension of that thinking.”
Other co-authors from CU-Boulder include Associate Professor Diana Nemergut, doctoral student Samantha Weintraub and Professor Alan Townsend, in whose lab the work was based. Other co-authors include Cory Cleveland of the University of Montana, William Wieder of the National Center for Atmospheric Research and Teresa Bilinski of St. Edwards University.

CU develops solar toilet for third world use

Innovative solar-powered toilet developed
by CU-Boulder ready for India unveiling
by CU-Boulder ready for India unveiling
A revolutionary University of Colorado Boulder toilet fueled by the sun that is being developed to help some of the 2.5 billion people around the world lacking safe and sustainable sanitation will be unveiled in India this month.
The self-contained, waterless toilet, designed and built using a $777,000 grant from the Bill & Melinda Gates Foundation, has the capability of heating human waste to a high enough temperature to sterilize human waste and create biochar, a highly porous charcoal, said project principal investigator Karl Linden, professor of environmental engineering. The biochar has a one-two punch in that it can be used to both increase crop yields and sequester carbon dioxide, a greenhouse gas.
The project is part of the Gates Foundation’s “Reinvent the Toilet Challenge,” an effort to develop a next-generation toilet that can be used to disinfect liquid and solid waste while generating useful end products, both in developing and developed nations, said Linden. Since the 2012 grant, Linden and his CU-Boulder team have received an additional $1 million from the Gates Foundation for the project, which includes a team of more than a dozen faculty, research professionals and students, many working full time on the effort.
According to the Gates Foundation, the awards recognize researchers who are developing ways to manage human waste that will help improve the health and lives of people around the world. Unsafe methods to capture and treat human waste result in serious health problems and death – food and water tainted with pathogens from fecal matter results in the deaths of roughly 700,000 children each year.
Linden’s team is one of 16 around the world funded by the Gates “Reinvent the Toilet Challenge” since 2011. All have shipped their inventions to Delhi, where they will be on display March 20-22 for scientists, engineers and dignitaries. Other institutional winners of the grants range from Caltech to Delft University of Technology in the Netherlands and the National University of Singapore.
The CU-Boulder invention consists of eight parabolic mirrors that focus concentrated sunlight to a spot no larger than a postage stamp on a quartz-glass rod connected to eight bundles of fiber-optic cables, each consisting of thousands of intertwined, fused fibers, said Linden. The energy generated by the sun and transferred to the fiber-optic cable system — similar in some ways to a data transmission line — can heat up the reaction chamber to over 600 degrees Fahrenheit to treat the waste material, disinfect pathogens in both feces and urine, and produce char.
“Biochar is a valuable material,” said Linden. “It has good water holding capacity and it can be used in agricultural areas to hold in nutrients and bring more stability to the soils.” A soil mixture containing 10 percent biochar can hold up to 50 percent more water and increase the availability of plant nutrients, he said. Additionally, the biochar can be burned as charcoal and provides energy comparable to that of commercial charcoal.
Most public toilets look like this
Linden is working closely with project co-investigators Professor R. Scott Summers of environmental engineering and Professor Alan Weimer chemical and biological engineering and a team of postdoctoral fellows, professionals, graduate students, undergraduates and a high school student.
“We are doing something that has never been done before,” said Linden. “While the idea of concentrating solar energy is not new, transmitting it flexibly to a customizable location via fiber-optic cables is the really unique aspect of this project.” The interdisciplinary project requires chemical engineers for heat transfer and solar energy work, environmental engineers for waste treatment and stabilization, mechanical engineers to build actuators and moving parts and electrical engineers to design control systems, Linden said.
Tests have shown that each of the eight fiber-optic cables can produce between 80 and 90 watts of energy, meaning the whole system can deliver up to 700 watts of energy into the reaction chamber, said Linden. In late December, tests at CU-Boulder showed the solar energy directed into the reaction chamber could easily boil water and effectively carbonize solid waste.
While the current toilet has been created to serve four to six people a day, a larger facility that could serve several households simultaneously is under design with the target of meeting a cost level of five cents a day per user set by the Gates Foundation. “We are continuously looking for ways to improve efficiency and lower costs,” he said.
“The great thing about the Gates Foundation is that they provide all of the teams with the resources they need,” Linden said. “The foundation is not looking for one toilet and one solution from one team. They are nurturing unique ideas and looking at what the individual teams bring overall to the knowledge base.”
Linden, who called the 16 teams a “family of researchers,” said the foundation has funded trips for CU-Boulder team members to collaborate with the other institutions in places like Switzerland, South Africa and North Carolina. “Instead of sink or swim funding, they want every team to succeed. In some ways we are like a small startup company, and it’s unlike any other project I have worked on during my career,” he said.
CU-Boulder team member Elizabeth Travis from Parker, Colo., who is working toward a master’s degree in the engineering college’s Mortenson Center in Engineering for Developing Communities, said her interest in water and hygiene made the Reinvent the Toilet project a good fit. “It is a really cool research project and a great team,” she said. “Everyone is very creative, patient and supportive, and there is a lot of innovation. It is exciting to learn from all of the team members.”
“We have a lot of excitement and energy on our team, and the Gates Foundation values that,” Linden said. “It is one thing to do research, another to screw on nuts and bolts and make something that can make a difference. To me, that’s the fun part, and the project is a nice fit for CU-Boulder because we have a high interest in developing countries and expertise in all of the renewable energy technologies as well as sanitation.”
The CU-Boulder team is now applying for phase two of the Gates Foundation Reinvent the Toilet grant to develop a field-worthy system to deploy in a developing country based on their current design, and assess other technologies that may enhance the toilet system, including the use of high-temperature fluids that can collect, retain and deliver heat.
