FORENSICS -- The telltale bone

Technology developed more than 100 years ago to wirelessly transmit electricity is being adapted to locate clandestine graves. Oak Ridge National Laboratory's Charles Van Neste and colleagues are transmitting electromagnetic waves to penetrate the ground and set up a resonance in buried bones. "The system consists of a transmitter and a receiver that collects the surface waves and passively integrates them through resonance over time," Van Neste said. He and colleagues Arpad Vass, Marc Wise and Lee Hively have discovered that human bone has a resonance at about 2,000 hertz, a fact they exploit to make this approach effective. This proprietary technology borrows from a method of energy transfer developed by Nikola Tesla early last century. [Contact: Ron Walli, (865) 576-0226; wallira@ornl.gov]

ELECTRICITY -- Eye on the grid

Through a network that consists of hundreds of low-cost monitors that plug into standard 110-volt outlets, GridEye can play a role in ensuring the reliability of the nation's power grids. The system, developed by researchers at Oak Ridge National Laboratory, provides real-time information about dynamic responses to conditions and can provide warnings of impending failures such as the Northeast Blackout of 2003. The monitors, referred to as frequency disturbance recorders, are installed in offices, school buildings and residences. "ORNL's most recent deployment of GridEye sensors focuses on portions of the grid where high penetration of renewables is planned," said Yilu Liu of the Energy and Transportation Science Division.
