Students take first-place in New Venture Competition

Baisikeli Ugunduzi

Some ideas just stick in your mind. At the Bob Mark Memorial Elevator Pitch Competition last November, Ben Mitchell presented his idea for fixing bicycle tires in Africa, so villagers could make a living. It was simple and meaningful, and we were floored. Six months later, so was everyone else.

He and Wade Aitken-Palmer took first-place in the New Venture Competition held recently at Central Michigan University. Their idea, called Baisikeli Ugunduzi (Swahili for “modern bicycle”), captured $30,000 for first prize and another $10,000 for Best Social Venture, for sustainability and social impact, among other reasons. Their invention is a tube that eliminates flat tires.

Mitchell, a PhD student in Mechanical Engineering-Engineering Mechanics, and Aitken-Palmer, a student in the Applied Natural Resource Economics Peace Corps Master’s International program, have been working on the business idea since last year, and Mitchell said the inspiration began with his stint in the Peace Corps a couple of years before that. Thanks to the big win, he is planning a trip to Kenya in May to begin with more market testing.

“We are working with bicycle taxi drivers, who can go through many tubes in a month,” Mitchell said. “The tubes will have to be produced in Taiwan, as there are no production facilities in Kenya.” Assembling will take place in Africa, however, and that will create some jobs. “Our first hire will be a mechanic,” he said. “And he could do some modifications as well.”

When they began, Mitchell said he had some catching up to do on the business side of things, but they did have a more thought-out design and a more developed prototype than most, thanks to their engineering backgrounds. And he has high hopes for the future. “Some 50 million sub-Saharan Africans depend on bicycles,” he said. “As our mission says, we work with mechanics and bicycle taxi unions to design, produce and distribute products that add value to working bicycles and improve the livelihoods of bicycle taxi drivers, messengers and those who earn a living on their bicycles.”

Mitchell also pointed out Central Michigan’s role in hosting the event. “They did a tremendous job coordinating the whole event, with all the judges and student teams,” he said. “It was very well orchestrated.” Central has also invited Baisikeli Ugunduzi back to talk about how it all develops in the future.

Gerald Savage, professor emeritus at Illinois State University, will present “Beyond Politeness: How Might We Make Social Justice a Central Value in Technical Communication Education” at 7 p.m., Thursday, March 29, in the Noblet Forestry Lecture Hall. There will be a reception to follow in the atrium.

Savage received master’s and PhD degrees in rhetoric and technical communication from Michigan Tech in 1991 and 1995. He will discuss communication across national and cultural boundaries and focus on “inequities of power and hierarchy.”

Two students from the geological and mining engineering and sciences department were runners-up at the Society of Exploration Geophysicists (SEG) Challenge Bowl recently. Josh Richards, a PhD candidate in geophysics, and Chad (Danford) Moore, a senior in applied geophysics, took second place at the Sixth Annual Sooner Challenge Bowl at the University of Oklahoma in Norman.

The SEG Challenge Bowl is an international contest testing students’ breadth and depth of knowledge about the field of geoscience. The quiz-show format features intense competition, as the contestants attempt to buzz in first with the answers to challenging geoscience questions.

Tech Students Converge in Lansing for Graduate Education Day

Published
By

Four graduate students are going to Lansing for Graduate Education Day, Thursday, March 29. Governor Rick Snyder has declared the week of March 26 as Graduate Education Week, and more than 50 students from universities and colleges across the state will meet with legislators at the Capitol Building in Lansing.

Students will meet with their hometown legislators to discuss their studies and future plans and will also present their research and degree-related projects.

Attending from Michigan Tech are:

  • Mark Hopkins, a PhD candidate in mechanical engineering from Charlotte. He will be discussing his work on in-space electric rockets.
  • Stephanie Groves, a PhD candidate in biological sciences from Scottville. She will be presenting on converting industrial waste to biofuels and other products.
  • Emily Gochis, a PhD candidate in geology from Ann Arbor. She will discuss geoscience education.
  • Andrew Drees, a PhD candidate in electrical engineering from Stevensville. He will discuss a “smart grid” power system for use on Michigan Tech’s campus.

The governor and legislature have acknowledged that graduate education is key to Michigan’s economic growth and stability. Graduate education in Michigan is highly productive, contributing directly to the well-being of the state and its capacity to meet the challenges of the future.

Last year, Michigan’s four-year public and private colleges and universities awarded more than 20,000 master’s degrees and 5,000 doctorates, with Michigan ranking ninth among states in the US for the number of research-based doctorates awarded.

Students Excel in International Poster Competition

Two graduate students, Brett Spigarelli and Howard Haselhuhn, took first and third place in the Minerals and Metallurgical Processing Journal Student Poster Contest, held Feb. 22 in Seattle. Both are PhD candidates in chemical engineering.

The contest was part of the SME (Society for Mining, Metallurgy and Exploration) Annual Meeting. Thirteen graduate students from all over the world entered posters in the event.

The Tech students’ advisor, Chair Komar Kawatra (ChE), is on sabbatical as a Fulbright scholar in India and flew to Seattle for the competition.

“I am very fortunate to be working with graduate students like Howard and Brett,” said Kawatra. “They are highly motivated and just outstanding. One day I expect them to be CEOs of major corporations.”

Spigarelli earned the top spot for his poster on optimizing a carbon-dioxide scrubber that removes 50 percent of the CO2 passing through.

The scrubber, an 11-foot bench-model plastic pipe packed with glass beads, has a water-based solution flowing through it. From below, carbon dioxide bubbles up, reacting with chemicals in the liquid. The process not only captures carbon, it binds it in a solid form, making an undisclosed product that can be used as a construction material. The liquid itself can be recovered and used again.

The group has received a patent and hopes to build a pilot plant in cooperation with industry partner Carbontec Energy Corp.

Spigarelli’s prize-winning poster focused on making the scrubber as efficient as possible. In particular, he developed a model for determining the ideal concentration of chemical in solution to strip out CO2. “You want to remove as much carbon as possible, but you don’t want to use excess chemicals, because you want to save the company money,” Spigarelli said. “This process will give you the best results.”

Haselhuhn’s third-place poster also focused on water chemistry. At an iron-processing facility, he studied the technology used to remove impurities from iron ore. He found ways to improve the process and significantly boost productivity.

“The iron ore is ground down into very small particles, which are mixed in water,” he said. “The larger particles, which contain more iron ore, settle quickly, and the smallest ones, containing silica, stay suspended.” However, Haselhuhn discovered, sometimes the raw ore contains high levels of magnesium, which translates into higher concentrations of magnesium in the water. In turn, that causes silica particles to cluster together and settle out with the iron, rendering the separation process ineffective.

“By compensating for the excess magnesium, companies could reduce the loss of iron in their concentration process,” Haselhuhn said. “The results of this research will save millions of dollars per year and reduce the loss of an important natural resource.”
