This article first appeared in Aviation Week's DTI. Small unmanned aerial vehicles (UAV) are effective battlefield surveillance platforms. But they suffer from limited battery power, which affects their range and their sensors' effectiveness, often making them expendable. A solution may lie in overhead power lines. A program by Defense Research Associates (DRA) and the Air Force Research Laboratory (AFRL) seeks to develop a small UAV that can land on a power line and recharge its battery by drawing energy from the cable.

The Active Denial System, the Pentagon's "pain ray," is a millimeter wave nonlethal weapon that has been at the center of controversy since it was publicly revealed in 2001. This is the second part of an interview with the Air Force Research Laboratory's Diana Loree, the ADS project manager, who has been with the program since 1993. (Here's the first part.) In today's entry, we focus on "System 2," the latest version of the weapon, which could eventually be sent to Iraq.
