Last Thursday, along with the live broadcasts from yet another grand illumination somewhere with 500,000 LED lights twinkling in some shopping mall, was a news item about a temporary power drop in our area. Because of trouble with a transformer somewhere the voltage dropped by 40% for about 0.07 seconds… That’s right, it wasn’t a power cut, just a reduction, for less than one tenth of a second. As a result, factories all over the area came to a halt, some shut down for a day or more, and a Toshiba semiconductor plant’s output in January and February may be cut by 20~30% as a result. Hard to believe, but it’s true.
