  •  This is hardly zero cost (1+ / 0-)
    Recommended by:

    You're totally neglecting the investment.  Low temperature waste heat from a power plant is waste heat for a reason;  you can't afford the investment to generate a trickle of power from it.  Using the waste heat for heating is a good idea, and has been done in New York City, among other places.  But if you have to run insulated water lines from an isolated power plant to other locations you quickly find you can't do it.

    (A lot of capital) + (small efficiency gains) = not going to happen in most cases.  Always check the ROI.

    •  District Heating (0+ / 0-)

      Casten says that district heating works only within a two to four mile radius of the source.

      The zero cost is the change in the regulations that allow people to make the investment without the regulatory hurdles they have to jump through now and the regulatory roadblocks that make such investment practically impossible in some cases.
