Wind Power Study to Provide Hopis with Answers

March 2, 2006

MESA, Ariz.- The Rosebud Sioux Tribe, located on the Rosebud Indian Reservation in south-central South Dakota, invested in wind energy more than two years ago as a way to provide energy for its community. Now it's considering expanding to a commercial wind farm and selling the excess, but they are finding that profiting from the energy is a bit more difficult than they first thought.

Before the Hopi Nation finds itself caught in the same gust of producing energy for its community and selling excess energy, the Hopi Tribal Council contacted the Department of Engineering at Arizona State University's Polytechnic campus to study whether the huge investment would be worth it.

The initial area where ASU will be investigating is on a reservation mesa next to land identified as the location for a new Hopi village located in northeastern Arizona. The Hopis are also investigating wind on land between Flagstaff and Winslow, an area that is considered to have wind speeds suitable for wind energy development, based on prior research and studies by the U.S. Department of Energy's Wind and Hydropower Technologies Program.

"We will monitor wind speed, frequency, duration and weather to see if wind energy is an alternate, clean option to power two new villages and older ones, as well as potential for economic viability," said Mark Henderson, engineering professor at the Polytechnic campus.

What prompted the Hopi's interest?

A planned shutdown of the Power Generating station in Laughlin, NV, while air pollution scrubbers are installed on the tall stacks will take at least two years to complete. The shutdown will result in the closing of the Hopi Black Mesa coal mine. The mine has had an exclusive contract with the Laughlin plant for many years. The mine shutdown will significantly reduce the Hopi Nation's income and significantly increase unemployment.

In addition to the potential economic impact, a switch to wind will have a dramatic impact on the environment, as there are no byproducts produced from the operation of wind turbines, unlike the coal plant, except maybe one - the experience for ASU students is priceless.

The Hopi Wind Turbine Assessment Project is an opportunity for the first class of engineering students at the Polytechnic campus to work on a real world hands-on project, where they are analyzing data and providing solutions that address the needs of a community. "The year-long project not only gives an applied experience for students, but it also gives them a short immersion in another culture, one that many know very little about," said Henderson.

On March 3 and 4, 30 ASU students will participate in erecting a metal tower and equipping it with a wireless connection and instrumentation to capture wind speed and direction, temperature and barometric pressure. The data will be collected daily on a computer located more than 150 miles away on ASU's Polytechnic campus in Mesa.

"Bringing together engineering undergraduates with graduate students from the Department of Mechanical and Manufacturing Engineering Technology, will enable data analysis and model creation that will help with making sound economic as well as technological turbine recommendations," said Henderson.

Because the actual tower is more than 150 feet tall and weighs nearly 1.5 tons, the tower was raised professionally. However, students had their own tower raising experience on the Polytechnic campus back in December.

"Students built their own 30 foot tower using polyurethane piping and following the specifications that came with the actual tower," said Henderson. "Students got a good lesson in physics, engineering precision and materials science from the experience."

In addition to the wind research, faculty members will visit Hopi High School and teach alternative energy and engineering topics in sciences classes to pique student interest in engineering and alternative energy.

If the results of the study and analysis are positive, this could be one of the first wind turbine operated by an American Indian tribe located in Arizona.

"There are about 13,000 Hopis living on the reservation and some of the villages have no electricity from the outside; some use solar power. If we prove that their return in wind turbines will be larger than the investment, this will influence the community for generations to come," said Henderson.

ASU celebrates Women's History Month

March 3, 2006

Throughout March, Arizona State University will highlight accomplishments and contributions of women during its annual Women’s History Month celebration. The department of Women’s Studies in the New College of Interdisciplinary Arts and Sciences at ASU’s West campus has developed many exciting events to acknowledge and celebrate the accomplishments and contributions of women in society.

Women’s History Month is an opportunity for the ASU community to become more aware of and receptive to the various voices and concerns of women. March festivities will feature an array of educational and entertaining activities including those listed below. Download Full Image

Tuesday, March 21: The department of Women’s Studies will sponsor a women’s photo exhibit. The exhibit features work by local photographer Tracy Rasinski, whose images capture the faces of the women and children assisted by Arizona Women’s Partnership. Arizona Women’s Partnership is a Phoenix non-profit that supports small, grass-roots, non-profit organizations through funding and publicity. (6:30 to 8 p.m., Fletcher Library.)

Thursday, March 23: “Arizona Highways” editor Peter Aleshire will lead a discussion on the impact of Arizona women in history. (6:30 p.m., Kiva.)

Tuesday, March 28: African American storyteller Fatimah Halim will perform her innovative narrative style, “One Woman Storyin’,” in a performance piece called “She’s so G.H.E.T.T.O.” Halim’s one-woman-show offers a collage of personal stories describing the “magical side of Harlem.” (6:30 p.m., University Center Building, La Sala A.) 

Wednesday, March 29: Laura Tohe, associate professor in the department of English, College of Liberal Arts and Science, will discuss Native American women in history, their issues and challenges. (6:30 p.m., University Center Building, La Sala B.)

Thursday, March 30: The department of Women’s Studies presents a panel discussion on issues regarding women’s health. Among others, the panel includes ASU’s department of Women’s Studies’ faculty and students. (6:30 p.m., University Center Building, rooms 265-266.)

Tuesday, April 4: Kathy Cano Murillo, a journalist for the “Arizona Republic” will share her experiences as a do-it-yourself Latina woman in her life story, “La Crafty Chica.” (6:30 p.m., University Center Building, rooms 265-266.)

ASU's West campus is located at 4701 W. Thunderbird Rd., Phoenix. For more information, call Women's Studies at (602) 543-3300. Persons requiring accommodations for disabilities are requested to contact us in advance at (602) 543-3300.
