This article was published in the May 2011 edition of the IEEE Smart Grid Newsletter. According to the authors, medium-term prospects for the smart grid will be among the key technology topics addressed next month at the IEEE’s Technology Time Machine conference in Hong Kong. The purpose of the small and, frankly, elite meeting is to assemble people who are betting their corporate and national futures on when critical technologies will mature and take off. To judge from preliminary assessments laid out in a white paper prepared for the conference, some technologies, such as cloud computing, already are at a hockey-stick inflection point, while others, such as the so-called "Internet of Things," will reach that point in perhaps ten years' time. With the smart grid, due to immense technical challenges and acute engineering shortages, the inflection point may be closer to two decades away.
