July 31, 2012 We are expecting a scorcher today and even hotter temperatures tomorrow. With the heat comes higher energy use because people are trying to cool down. Xcel Energy needs your help. They have officially declared and energy alert.
July 18, 2012 I know, I couldn't believe it either when I read that Xcel is giving away free electricity. I mean who couldn't use some free electricity especially in the summertime when the AC is running all the time. So what's the catch?
One of the toughest things to teach Air Force pilots who guide unmanned attack drones is how to accurately spot targets in complex radar images. Researchers, however, have found a way to cut that lengthy training time in half.
Delivering a mild electrical current to pilots’ brains through EEG electrodes placed on the scalp — a process called transcranial direct current stimulation (TDCS) — can accelerate learning and improve pilot accuracy. In addition, that accuracy is sustained for up to 40 minutes, whereas it otherwise typically declines after 20 minutes.
