Wireless sensors could protect US power grid
The NewScientist has an article that talks about a new technology that could soon help protect the US power grid from problems using a network of compact wireless sensors.
The sensor boxes will connect to one another using wireless links, and will feed information on what is happening on the grid back to a central control station. They will run on batteries so they can keep relaying information if the power is cut, while future models may also have solar panels. The control system will then make decisions on how to reroute power around any problems detected.
This technology could’ve been very useful to us Canadians back in 1998, when Quebec was hit by one of the worse ice storm to ever be recorded in modern history. I remember that most of the province was out of power for about 2 weeks, right in the middle of winter. While I thought the situation was great fun, a lot of people had to be evacuated from their homes and didn't appreciate the experience very much.
