And in a sign of the huge energy draw from the tech show, once the crowds were let back in, the return to full, blazing electronic glory was slow.
In possibly the worst thing that could happen at a tech show, power went down across several halls at the Las Vegas Convention Center during CES at 11:15 PT. "We are working hard to resolve this and appreciate your patience", the event's official Twitter account said. We are opening Central Hall.

The association said power was restored within minutes to the 3.2 million-square-foot convention center's South Hall, where many gaming companies had exhibits, but other areas took longer - Central Hall, home to Samsung Electronics, LG Electronics, Sony, Panasonic, Intel, Qualcomm and Toshiba, among others, remained without power into the afternoon.
