KNOXVILLE—The University of Tennessee in Knoxville is donating the Living Light House— its award-winning, solar-powered project—to the Children’s Museum of Oak Ridge.

The Living Light House will move to its permanent home on Saturday, May 17. Starting at 7 a.m., the 750-square-foot, zero-energy structure, will be transported from the UT Gardens to the Oak Ridge museum at 461 W. Outer Drive. The move is expected to take several hours.

“The house has served as an ambassador for good design and energy efficiency,” said James Rose, UT architecture lecturer and lead faculty member of the Living Light project. “One of the most satisfying things about giving tours of the house is the response from children. Young people are always fascinated by the house and leave it excited about the future. I cannot think of a better place for the Living Light house to carry on this mission than at the Children’s Museum of Oak Ridge.”

The Living Light House, which was built through the efforts of more than 200 UT students, was an entry to the 2011 U.S. Department of Energy Solar Decathlon in Washington, D.C. It has traveled nearly 6,000 miles, been toured by more than 50,000 visitors, and was on exhibit at the 2012 Smithsonian Folklife Festival. [Read more…]

KNOXVILLE—The state of Tennessee is selling one of the greenest homes in the state—the New Norris House.

Sealed bids will be taken through 1:30 p.m. (CST) on May 5. An open house will be held April 12, 2-4 p.m., at 143 Oak Road in Norris.

The New Norris House was completed in 2011 after a student-led team at the University of Tennessee in Knoxville worked for three years to bring the concept, first conceived in a classroom, to a modern and appealing home.

The house is a technologically advanced reinterpretation of the historic homes first built by the Tennessee Valley Authority in 1933 as part of the Norris Dam project. It has become a nationally recognized model for efficient and sustainable living. [Read more…]

KNOXVILLE—Football season is still months away, but those needing a quick fix before fall can get a chance to see a version of the game played by competitors functioning like well-oiled machines.

The FIRST Robotics Competition Smoky Mountain Regional returns to the Knoxville Convention Center March 26-29, and is centered around a game featuring strong elements from football and soccer called Aerial Assist.

The idea behind Aerial Assist is that the 50 teams at the competition—from as far away as St. Louis and as close as the L&N STEM Academy across World’s Fair Park—will each build a robot capable of throwing, kicking, or running with a round ball with the goal of scoring a goal at each end of a field, or one capable of playing defense.

The University of Tennessee’s College of Engineering in Knoxville helps sponsor the event along with various technology and industry organizations such as NASA, Oak Ridge National Laboratory, and the Tennessee Valley Authority. [Read more…]

KNOXVILLE—The U.S. Department of Energy recently released a report co-chaired by Jack Dongarra, a distinguished professor at the University of Tennessee in Knoxville, in which he stresses the importance of prioritizing research into high-end mathematics to help keep the United States on the cutting edge of computing.

“Exascale computing (capable of one quintillion floating point operations per second) will enable us to solve problems in ways that are not feasible today and will result in significant scientific breakthroughs,” said Dongarra, of UT’s Department of Electrical Engineering and Computer Science. “However, the transition to exascale poses numerous scientific and technological challenges.”

Dongarra, one of five National Academy of Engineering members on the faculty of UT’s College of Engineering, said that increased funding for the development of new models and ways of gathering data is key to unlocking a number of those challenges. [Read more…]

KNOXVILLE—Part of a national effort to advance science, technology, engineering, and mathematics undergraduate education is being directed by a professor at the University of Tennessee in Knoxville.

Three five-day National Science Foundation Ideas Labs—one for biology, one for engineering, and one for geosciences—are being held this month through April 4 in the Washington, D.C., area. Each lab involves participants from various disciplines and backgrounds, as well as prospective employers and representatives of scientific and professional societies. The goals of the labs are to incubate innovative approaches to improve undergraduate STEM education and produce research agendas that address workforce development needs.

A UT press release said Louis Gross, director of the university’s National Institute for Mathematical and Biological Synthesis, will serve as director of the Biology Ideas Lab, to be held March 30 to April 4 in Leesburg, Va. [Read more…]

SEATTLE—University of Washington scientists have built the thinnest-known LED that can be used as a source of light energy in electronics, thanks in part to a breakthrough by researchers at Oak Ridge National Laboratory and University of Tennessee in Knoxville.

The LED is based off of two-dimensional, flexible semiconductors, making it possible to stack or use in much smaller and more diverse applications than current technology allows.

“We are able to make the thinnest-possible LEDs, only three atoms thick yet mechanically strong,” said Xiaodong Xu, a UW assistant professor in materials science and engineering and in physics. “Such thin and foldable LEDs are critical for future portable and integrated electronic devices.”

Most consumer electronics use three-dimensional LEDs, but they are up to 20 times thicker than the LEDs being developed. [Read more…]

KNOXVILLE—Some of the best and brightest undergraduate students from around the United States gathered at the University of Tennessee in Knoxville recently for the chance to meet top experts in the field of nuclear engineering, including representatives from federal sites in Oak Ridge.

“This area really is the birthplace of a lot of activities related to nuclear engineering,” said Wesley Hines, head of UT’s Department of Nuclear Engineering, which sponsors the annual event. “Some of these kids don’t realize all of the nuclear-related opportunities that exist here until they do this program. What we hope to achieve is to let people see all that is possible, all that is already in place when they come here.”

The sessions gave prospective graduate students a chance to mingle with some of the biggest names in nuclear research and energy, including from the Y-12 National Security Complex, Oak Ridge National Laboratory, the UCOR facilities at the East Tennessee Technology Park, and Tennessee Valley Authority, as well as with UT faculty and students.  [Read more…]

KNOXVILLE—With the installation of LED fixtures, the Thompson-Boling Arena at the University of Tennessee in Knoxville is one of the first in the world to feature lights that are smaller, brighter, and up to 85 percent more efficient than conventional arena metal halide lights.

The technology—developed and manufactured by Oak Ridge-based LED North America at the Tech 20/20 incubator facility in Oak Ridge, incorporating an Oak Ridge National Laboratory technology, and installed by Knoxville-based Bandit Lites—is being “premiered” at the state’s research university inside the largest on-campus single-sport arena in the country.

The light-emitting diode fixtures use an ORNL-developed lightweight graphite foam that cools the LED, making them more efficient and reliable. This enables 90 400-watt LED fixtures to bathe the arena’s floor with 200 foot-candles per square foot, compared to the 130 foot-candles produced by the arena’s existing 110 1,100-watt fixtures.

LED North America’s SuperSport luminaires have the potential to revolutionize sports and entertainment venues worldwide. UT officials are looking forward to participating in this effort and to seeing the results—and the savings. [Read more…]
