What if charging your plug-in electric vehicle was as easy as parking it? No need for cords or cards. Just as Wi-Fi has freed consumers of wires when accessing the Internet, wireless charging technology may soon be as widespread, thanks to research supported by the U.S. Department of Energy.

With support from the Vehicle Technologies Office, Oak Ridge National Laboratory and Hyundai America Technical Center Inc. have been working since 2012 to demonstrate wireless charging on a variety of vehicles. ORNL is working with a mix of Toyota vehicles, including models of the all-electric RAV 4, plug-in hybrid electric Prius, and all-electric Scion iQ, while Hyundai America Technical Center Inc. is testing its technology on five all-electric Kia Souls.

The technology behind wireless charging creates a connection between a transmitting pad on the ground (such as in a garage) and a receiving pad integrated on the bottom of the vehicle. In the projects ORNL is leading, the transmitting pad is connected to a 240-volt outlet and generates a magnetic field of a certain frequency. When the coil in the receiving pad is tuned to oscillate at the same frequency, the magnetic field will generate a current in the receiving coil, charging the vehicle’s battery. [Read more…]

Traffic on Highway 58 and Highway 95 could be affected for two weeks starting Thursday by large, slow-moving equipment removing parts from a former electrical switchyard at the East Tennessee Technology Park in west Oak Ridge.

The work is being done by the U.S. Department of Energy’s Oak Ridge Office of Environmental Management. It’s part of the ongoing cleanup work at ETTP, the former K-25 site.

Workers are removing, disposing, and recycling components from a former ETTP electrical switchyard, known as K-732 Switchyard.

“For the next two weeks, this project requires the use of a specialized trailer on public highways to transport three large condensers that each weighs approximately 110 tons,” a press release said. “Motorists transiting the area during this time should be alert for slow-moving vehicles and expect occasional delays.” [Read more…]

An environmental assessment has been completed for the transfer of 170 acres at Heritage Center for a general aviation airport in west Oak Ridge, and the assessment found no significant impact, officials said Tuesday.

The assessment was completed by the U.S. Department of Energy Oak Ridge Office of Environmental Management. The land would be transferred to the Metropolitan Knoxville Airport Authority.

In August, officials said conditions are subject to change, but plans then called for starting construction on the airport at the former K-25 site in 2018. An estimate at that time said the airport could cost between $30 million and $40 million.

The airport would have a 5,000-foot runway that would accommodate general aviation aircraft including corporate jets, private airplanes, and emergency medical services aircraft. A development plan shows the airport at the south side of Heritage Center along Oak Ridge Turnpike, or State Route 58. [Read more…]

Demolition started Monday on K-27, the last of the big five uranium-enriching buildings at the former K-25 site, and officials expect the work to be complete by the end of the year.

The five buildings—K-25, K-27, K-29, K-31, and K-33—once used a process called gaseous diffusion to enrich uranium for atomic weapons and commercial nuclear power plants. Officials credit them for helping to win World War II and end the Cold War, and for playing significant roles in technological developments and the nuclear industry.

The K-25 site, which is now known as East Tennessee Technology Park or Heritage Center, was built during World War II as part of the Manhattan Project, a top-secret federal program to build the world’s first nuclear weapons. The site is now slowly being converted into a large industrial park.

“The majority of the property will be reused,” said Ken Rueter, president and project manager for UCOR, or URS |CH2M Oak Ridge LLC, the U.S. Department of Energy’s cleanup contractor in Oak Ridge. [Read more…]

Note: This story was last updated at 11:35 a.m. Feb. 3.

Protomet Corporation on Tuesday announced a $30 million, 200-job expansion, but the landlocked company could move to another county—or even another state.

Protomet is now located in the Bethel Valley Industrial Park in south Oak Ridge.

The company hopes to break ground on the 100,000-square-foot expansion in June and plans to add 200 new jobs during the next five years. Protomet now has 70 workers in a 40,000-square-foot building on eight acres, so the company would more than triple in size.

Besides staying put, Protomet is also looking at sites in Roane County (the Horizon Center in west Oak Ridge), Loudon and Monroe counties, and South Carolina. The company is looking at some tracts of land outside Anderson County that are more than 25 acres. Protomet needs about 25-30 acres for the expansion, and right now, it doesn’t have it. [Read more…]
