    Basic data collection for a small water system.

    Our tiny community water system consists of a spring-fed 20,000 gallon tank that distributes to 30 homes. We want to add some instrumentation to this system so that we can monitor use and plan for the future. We would like to collect data on in- and out-flows to the tank and the tank level...

    Typical power transmitted over lines?

    Thus the whole government angle. New standards and maybe even a new regulatory body is going to come out of the current Senate investigation. Utilities are going to have to raise rates to meet the new requirements but in the current security environment they should be able to make the case for...

    Typical power transmitted over lines?

    What I'm thinking of are buffering nodes at strategic points on the grid. Each node would contain both an electrical source (a large fuel cell with hydrogen tank) and a sink (a small plant that generates and stores hydrogen from electricity). The node would be able to react to short-term...

    Typical power transmitted over lines?

    THANK YOU everyone, by the way. This is just the kind of back-of-the-envelope information that I was looking for.

    Typical power transmitted over lines?

    Regarding hydrogen generation as storage: Let's say there's a transmission line between power plant and a load (a bunch of houses) and that line fails. In that case the plant's power must be immediately either shunted to other lines (possibly overloading them and leading to more failures) or...

    Typical power transmitted over lines?

    Friends have raised the idea of using hydrogen generation coupled with fuel cells as a buffering mechanism on major transmission lines. When a line fails, the supply side would store electricity by generating hydrogen while the load side would continue to generate power using hydrogen...
