NA-102, from February 15th through to March 8th. He will also participate 
in the SSB portion of the "Coupe du REF" contest on the 25th and 26th of 
February as well as the ARRL DX SSB contest on the 4th and 5th of March. 
QSL via LoTW, eQSL, or direct to F1DUZ.

Saudi Arabia's Founding Day are being commemorated by special event 
stations 7Z3FD, 8Z3FD and HZ3FD until the 22nd of February, which is the 
actual date of the celebration. QSL via HZ1SAR; the logs will be uploaded

KICKER: WEARABLE FABRIC HELPS 'SING THE BODY ELECTRIC'

PAUL/ANCHOR: Our final story comes from Ralph Squillace, KK6ITB. Prepare 
to get a real charge out of it. A real charge.

RALPH: OK, so here's a real yarn for you. Yes - a real yarn, the kind of 
which sweaters are made. These are high-tech fibers known as twistrons, 
which scientists developed about five years ago. Unlike conventional 
knitting yarns, twistrons are spun from carbon nanotubes, resulting in 
lightweight material that increases in density whenever it is twisted or 
stretched. The result from all that stretching isn't necessarily a 
better-fitting sweater, however -- it's voltage that can drive an 
electric current. To researchers like Ray Baughman at the University of 
Texas at Dallas, twistrons present a promising way to make use of the 
motion of the body to power an electronic device because it taps into the 
wearer's mechanical energy. Scientists say the energy conversion 
efficiency of twistrons has improved over the years, up from 17.4 percent 
from twisting to an impressive 22.4 percent.

Researchers recently used an array of twistrons weighing 3.2 milligrams 
to charge a supercapacitor capable of powering a small device such as an 
electronic watch or five small LEDs.

While the researchers aren't quite at the point of releasing their own 
clothing line, they do have their eye on harnessing the motion of ocean 
waves using twistrons to create electric power. We hams can only imagine 
dressing for success like this, going out for a summit activation or for 
Field Day. The possibility is electrifying.

This is Ralph Squillace, KK6ITB.
