Get a First Glimpse of the New University of Michigan Solar Car

29.05.2009
The University of Michigan's reigning North American Solar Challenge champions will soon unveil their solar car that will compete in an 1,800-mile race across Australia this fall.

At 3 p.m. on June 5 at the Henry Ford Museum in Dearborn, the Solar Car Team will reveal "Infinium." This 10th-generation U-M solar vehicle will race against more than 50 teams in the Global Green Challenge, formerly the World Solar Challenge. The six-day competition starts Oct. 25.

Team strategy director Alex Dowling, a senior chemical engineering undergraduate, says Infinium will be the most competitive car in the team's history. The car can go for more than 200 miles without the sun.

"Infinium builds on our continued success and the knowledge we've learned from previous teams," Dowling said.

The car has a lithium battery, space-grade solar cells comparable to those NASA uses in satellites, and an in-wheel electric motor designed for solar cars that peaks at 98 percent efficiency.

Advanced computer simulations predict it will break records, but Dowling explained why speed isn't necessarily king in this case. Strategy is more important, he said.

"There's a limited amount of energy coming in from the sun, making it infeasible to drive the speed limit the entire race," Dowling said. "There's a need for race strategy to decide how fast we should go, and when, if we want to cross the finish line first."

Michigan won the 2008 North American Solar Challenge to become five-time champions in that race. The team with a 20-year history has also finished third in the World Solar Challenge three times.

In the most recent world event, an early crash set the students back and they finished seventh. Another team just ahead of Michigan slowed suddenly, causing a chain reaction and the solar car hit its support vehicle. This year's team has spent more time practicing with its caravan.

"We're making sure we're comfortable in all driving scenarios and we're placing more emphasis on having a cohesive team," Dowling said.

Infinium will make its initial appearance just feet away from where the first Michigan solar car, Sunrunner, is displayed at the Henry Ford Museum.

Speakers at the unveiling include Susan Fancy, a founding member of the Michigan Solar Car Team; David Munson, the Robert J. Vlasic Dean of Engineering; team project manager Steven Hechtman; and team business director Julia Hawley. The team will also honor its sponsors, including Ford Motor Co., General Motors Corp., Delta Air Lines, and the University of Michigan College of Engineering.

The public event is in the Sally and Wendell Anderson Theater in the museum at 20900 Oakwood Blvd., Dearborn, Mich.

The UM Solar Car Team is a 501(c)(3) non-profit and is an entirely student-run organization.

Michigan Engineering:
The University of Michigan College of Engineering is ranked among the top engineering schools in the country. At more than $130 million annually, its engineering research budget is one of largest of any public university. Michigan Engineering is home to 11 academic departments and a National Science Foundation Engineering Research Center. The college plays a leading role in the Michigan Memorial Phoenix Energy Institute and hosts the world class Lurie Nanofabrication Facility. Michigan Engineering's premier scholarship, international scale and multidisciplinary scope combine to create The Michigan Difference.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
