Last month, Wired celebrated the 120th anniversary of the electricity meter. More specifically, the anniversary of the patent for the first really commercially viable electro-mechanical meter. Edison, being Edison, had come up with others before, but they “didn’t scale”, and were messy because they were chemical, not mechanical. This post provides a nice synopsis of the development of the induction watt-hour meter and its importance in the development of the electricity industry.
Wired also accompanies this post with a photo gallery of the history of electricity. The last photo in the series is of Tendril’s Insight in-home display, of which I’m a big fan, as I alluded to in my recent post about whether or not smart grid devices are transactive.
