Penn State Wind Energy Club Breezes to Victory in Collegiate Wind Competition

    The Penn State Wind Energy Club took first place overall and first place in the Tunnel Testing contest at the DoE Collegiate Wind Competition 2017 Technical Challenge.

UNIVERSITY PARK, Pa. — The Penn State Wind Energy Club breezed through the field at the U.S. Department of Energy Collegiate Wind Competition 2017 Technical Challenge, held April 20-22 at the National Wind Technology Center near Boulder, Colorado—earning its third overall victory in four years at the Collegiate Wind Competition.

The Penn State team, comprised of 11 students from various engineering majors, beat out nine other teams from across the nation, earning a total of 762 points out of a possible 1,000, which was 161 points ahead of the second-place finisher. The team also took first place in the Tunnel Testing contest with a score of 365 points out of a possible 450.

“The advisers of the team are extremely proud of the Wind Energy Club students for their hard work on this wind competition activity,” said Susan Stewart, lead strategic adviser of the team and senior research associate and assistant professor of aerospace engineering. “They are getting really great experience in systems thinking and putting their overall engineering education to work as they tackle the challenges of this project.”

The Collegiate Wind Competition 2017 Technical Challenge is an opportunity for institutions that participated in the U.S. Department of Energy Collegiate Wind Competition 2016, which Penn State won, to capture the spirit of team collaboration and apply the acquired skills and knowledge to the technical challenge event. The competition focused on testing a small-scale wind turbine in a portable wind tunnel designed and built by the National Renewal Energy Laboratory. This year’s event also added the challenge of testing in yawed inflow to address changing wind directions.

“Even though we won the main event last year, we came in third place in 2015 at the exact same technical competition in the exact same location, so we had some extra motivation this year,” said Jason Cornelius, aerodynamics team lead, vice president of the Wind Energy Club and a senior in aerospace engineering. “It was all new to us in 2015, and since all of the 2014 team members had graduated, there wasn’t any significant knowledge transfer to our team. However, we spent the last two years trying to build a turbine based on what we learned that would allow us to come back and pull out a victory. It was pretty exciting to redeem ourselves.”

Each team was required to design, build and present a unique, wind-driven power system; document the design of the turbine and load in a technical report; and present on the design and report to a panel of judges.

Additionally, teams participated in a bonus event—an educationally focused siting challenge that required students to balance competing objectives of maximizing power production, minimizing costs and minimizing environmental and community impact.

Building on its innovative, winning turbine design for the 2016 competition, the team was able to improve the design and efficiency of this year’s turbine by focusing on several key generator components according to Mitch Proulx, generator team lead, president of the Wind Energy Club and a senior in mechanical engineering.

“We used a one-stage generator last year, which performed extremely well, but we wanted to add more stages this time to generate even more power,” said Proulx. “By using three stages, along with replacing some of the iron parts with 3D-printed parts, we were able to significantly increase our power because the generator was not only more efficient, but it weighed 22 percent less than it used to weigh.” 

The team also realized gains through improvements to its electrical components which were designed by Patrick Nicodemus, electrical design team lead and a senior in electrical engineering and mathematics.

“Patrick was able to design a circuit that would regulate the voltage so as to not exceed the maximum limit for the competition, morphing itself as it drew power from the turbine,” said Cornelius. “It was crazy.”

Senior members of the team will be passing along their knowledge to their teammates to help them and future members continue their success.

“The Collegiate Wind Competition Technical Challenge provides a great opportunity for senior members of the team to mentor underclassmen and provide them with guidance towards being future leaders for the Penn State Wind Energy Club and upcoming Department of Energy Collegiate Wind Competitions,” said Stewart.

The team will now focus its efforts on defending its title at the Collegiate Wind Competition 2018, which will take place during the annual American Wind Energy Association WINDPOWER Conference and Exhibition in Chicago, Illinois, May 7–10, 2018. Penn State will compete against 11 other universities.

Cyborg Bacteria Outperform Plants When Turning Sunlight Into Useful Compounds (Video)

Photosynthesis provides energy for the vast majority of life on Earth. But chlorophyll, the green pigment that plants use to harvest sunlight, is relatively inefficient. To enable humans to capture more of the sun's energy than natural photosynthesis can, scientists have taught bacteria to cover themselves in tiny, highly efficient solar panels to produce useful compounds.

Scientists Create 'Diamond Rain' That Forms in the Interior of Icy Giant Planets

In an experiment designed to mimic the conditions deep inside the icy giant planets of our solar system, scientists were able to observe "diamond rain" for the first time as it formed in high-pressure conditions. Extremely high pressure squeezes hydrogen and carbon found in the interior of these planets to form solid diamonds that sink slowly down further into the interior.

Researchers Create Molecular Movie of Virus Preparing to Infect Healthy Cells

A research team has created for the first time a movie with nanoscale resolution of the three-dimensional changes a virus undergoes as it prepares to infect a healthy cell. The scientists analyzed thousands of individual snapshots from intense X-ray flashes, capturing the process in an experiment at the Department of Energy's SLAC National Accelerator Laboratory.

Nanotechnology Gives Green Energy a Green Color

Solar panels have tremendous potential to provide affordable renewable energy, but many people see traditional black and blue panels as an eyesore. Architects, homeowners and city planners may be more open to the technology if they could install colorful, efficient solar panels, and a new study, published this week in Applied Physics Letters, brings us one step closer. Researchers have developed a method for imprinting existing solar panels with silicon nanopatterns that scatter green light back toward an observer.

"Getting to 80%" on Energy Cutbacks Cannot Occur Unless Behaviors Change

California's plan to cut energy consumption by 80 percent by 2050 cannot be achieved with current proposed policy changes because most solutions focus on changing technologies rather than changing behavior, a new UC Davis study suggests.

New Battery Material Goes with the Flow

Scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory have engineered a new material to be used in redox flow batteries, which are particularly useful for storing electricity for the grid. The material consists of carefully structured molecules designed to be particularly electrochemically stable in order to prevent the battery from losing energy to unwanted reactions.
