Researchers at Oak Ridge National Laboratory have demonstrated a 120-kilowatt wireless charging system for vehicles—providing six times the power of previous ORNL technology and a big step toward charging times that rival the speed and convenience of a gas station fill-up.

The wireless system transfers 120 kilowatts of power with 97 percent efficiency, which is comparable to conventional, wired high-power fast chargers. In the laboratory demonstration, power was transferred across a six-inch air gap between two magnetic coils and charged a battery pack.

ORNL researchers created and demonstrated the world’s first 20-kilowatt wireless charging system, which is being modified for applications such as commercial delivery trucks.

“It was important to maintain the same or smaller footprint as the previous demonstration to encourage commercial adoption,” said project lead Veda Galigekere of ORNL’s Power Electronics and Electric Machinery Group. [Read more…]

For the U.S. military, accurate weather prediction is vital to both the planning and execution of worldwide missions. To extend its weather modeling capabilities, the U.S. Air Force has joined the computing experts at the U.S. Department of Energy’s Oak Ridge National Laboratory in a strategic collaboration that includes procurement and operation of a new high-performance weather modeling computer system. Key members of the Air Force and ORNL teams, including computing and global security team members, gathered on July 10 to kick off this project and tour the facilities supporting the new system, according to a story posted by ORNL.

The Air Force 557th Weather Wing provides the Air Force and Army with global- and regional-level numerical weather model forecasts. With the increasing scale of the requirements for the new system, the Air Force and ORNL identified an opportunity to take advantage of the capabilities of ORNL’s National Center for Computational Sciences—including expertise in high-performance computing facilities and infrastructure, systems administration, computing procurement and acquisition, and system operations, the story said.

“We learned about the Air Force’s needs, and it was immediately clear that ORNL could help them solve their problems,” said Jim Rogers, NCCS director of computing and facilities. “We can integrate the Air Force weather team’s needs into our facilities in a cost-effective way, leveraging our capabilities to deliver exceedingly high availability to support their mission.” [Read more…]

A company called Qrypt Inc. will incorporate a quantum random number generator developed by Oak Ridge National Laboratory into existing encryption techniques, strengthening cyber security, a press release said.

Qrypt has exclusively licensed the technology from ORNL, a U.S. Department of Energy laboratory. It’s intended to help defend against cyber attacks, including those posed by quantum computing.

Encryption uses codes or mathematical algorithms to make information such as messages or stored data unintelligible to unauthorized readers. Quantum computers make use of the quantum states of electrons or other particles to store and process information as quantum bits.

The press release said Qrypt will incorporate ORNL’s quantum random number generator into the company’s existing encryption platform. It will use inherent quantum randomness to create unique and unpredictable encryption keys enabling virtually impenetrable communications, the press release said. [Read more…]

Federal site cleanup workers reported in August that they had begun removing contaminated sludge and debris from tanks, sumps, and valve boxes at Oak Ridge National Laboratory’s liquid and gaseous waste operations using a powerful, new trailer-mounted vacuum.

The equipment has already enhanced safety and operational efficiency, according to the U.S. Department of Energy Office of Environmental Management.

“Without the vacuum, personnel would be required to fully dress in personal protective equipment and remove the sludge and debris with shovels and buckets,” DOE said. “In addition to being closer to contaminated materials in confined spaces, workers would face an increased chance of slips and falls while climbing in and out of slippery areas in the protective suits.”

Using the vacuum technology has eliminated the risk of heat stress for employees, who would otherwise perform manual labor in protective suits during the hot Tennessee summer, DOE said. [Read more…]

For the first time since 2012, the United States has the most powerful supercomputer in the world, and it’s again located at Oak Ridge National Laboratory.

The new supercomputer, called Summit, is capable of 200 petaflops, or 200,000 trillion calculations per second. Equipment delivery for Summit was completed in March, and officials celebrated the launch of the supercomputer in a ceremony attended by U.S. Energy Secretary Rick Perry on June 8.

The last time the United States had the top supercomputer was in November 2012. That machine, which is still in use, is named Titan, and it’s also at ORNL. It’s now number seven on the semiannual TOP500 list, which was released Monday.

China had held the top spot since June 2013, and the country had held the top two spots since June 2016. That ended with Monday’s TOP500 announcement. Previously at number one and number two, the top two Chinese supercomputers have fallen to number two and number four.

ORNL, a U.S. Department of Energy laboratory, now has two of the top seven systems on the list. They are Summit at number one and Titan at number seven. The United States now has six of the top 10 machines, according to the TOP500 list. [Read more…]

Oak Ridge National Laboratory again has the world’s most powerful supercomputer. It’s also the world’s smartest supercomputer, a machine that can learn—and run software that will write software.

The supercomputer, called Summit, is capable of 200 petaflops, or 200,000 trillion calculations per second. During a Friday afternoon ceremony, U.S. Energy Secretary Rick Perry said Summit can save 30 years worth of desktop data in one hour. It is millions times faster than a really good high-end desktop, said Ginni Rometty, IBM chair, president, and chief executive officer.

A water-cooled IBM system, Summit is presumed to have bumped China from the top spot, at least among open-science systems or supercomputers that aren’t classified. It has successfully run the world’s first exascale scientific calculation.

“We know we’re in competition, and it matters who gets there first,” Perry told several hundred people at the Friday afternoon ceremony at ORNL, a U.S. Department of Energy laboratory. “We reached a pinnacle today.”

Researchers at ORNL could find the cure for Alzheimer’s disease or cancer, Perry said. Winning the global supercomputing race could have benefits for all of humanity, said Jensen Huang, NVIDIA founder, president, and CEO. [Read more…]
