    Ground heat assisted heat pumps are a great idea whose time seems to have come.

    One solution for our energy needs and for our current financial crisis might be to make low interest loans available for installation of these puppies.

    We could cut our energy needs - the most efficient way of getting coal out of our mix.  Less electricity to run air exchange heat pumps or electric heaters.

    It would also cut down our need to import petroleum to make fuel oil for those who current heat with oil.

    And we could put a lot of "working people" to work drilling holes in the ground and hooking up the equipment.

    There's an interesting housing development in Canada where they put heat collectors (loops of black plastic pipe) on tops of the garages and pump heat into the ground during  the summer.  Then in the winter they use that stored heat to boost the performance of the heat pumps.

      drilling down to warm ground water like others have done is seeking to use direct heat rather than generating power.  In many places the heated water from power plants is used for many purposes, including heating buildings, rather than killing fish.

        Where there is hot ground water to be used.

        Iceland does a lot of this.  But Iceland is fairly unique.

          YMCA, think recreation center, put in geothermal heat pumps, and it heats its pool for the cost of running some fans.  The entire energy bill for the facility is less than my house.

          Another area around a cheap golf course did all of their units with geothermal heat pumps.  They pay 15-20 a month in heating costs in norther Iowa, basically on the Mn border.

          With the right policies in place, we can get people to work and stop buying oil.

            stop burning coal... fixing our oil use is a different set of technologies until we get to the next generation of advanced electrical energy storage.

            But replacing coal is a very definitely worthwhile goal all by itself.
