    :)Hi Team:)

    Thanks for waiting. Last year, I posted new geothermal heat exchange technology on this Web-Site. Non-Provisional Patent was finally filed on Dec 31st of 2008. And I updated web-site including brief technology-update and invitation of investors.

    The noble new geothermal heat exchange system is now named as NobleGeofurnace Heat Pump System utilizing GeoBattery System as a geothermal heat exchange system composed of heat depot(s) and heat transfer lines.

    This new system is compatible to any existing geothermal heat pumps both 'DX' and 'Water Source'.

    This new system does not require extensive excavation and drilling with compatible or even better efficiency.

    The payback period of this systm for new building is almost zero year and retrofit building depends on the condition of the house but significantly less than current closed-loop system either DX or water-source.

    I am currently looking for the partner to manufacture heat-depot and heat transfer lines.

    Precise information, please refer to

    for further inquiries, please contact

    After having reviewed the link

    It is late. So I may have to re-think, but isn't the rate limiting step in all this the thermal conductivity of the soils?

    One could use a cube of pure water (pretty ideal transfer media or "heat depot") as a heat source, and while it would look good at first, it still needs heat moving "in to it" or "away from it" eventually.

    The long spatial design of ground loops is to limit interference between the pipes. All the pipes could be bundled up in a much smaller total volume and still have the same contact with the earth, but there is interference between the pipes in this manner.

    I admit, I may be missing something...

    heat depot?

    If I am reading this correctly it is just a dx system, with the heat depot containing a medium designed for exchange?
    It is a idea that would address the issue of ph in the soil which prohibits dx on the penninsula. However the "depot" is going to rely on soils type to facilitate transfer. What is the projected efficency of the depot for a given site, dry clay, vs. saturated sand?

    Brook and new system

    That is good point, having running brook. This is not lake system or such a like. The distance from HD to the brook is over 50 ft. And there is not active flow under ground water table.
    HDs were installed above the level of the brook.
    Also you would like to think about what size of lake do you need to run heat-pump.

    Hope it helps your understanding..

    Eric you are absolutely right it is 'DX' system in heat depot. This HD could be applied to water source system and I am now installing into a new building.
    The issues are
    (1)where or not 'HD'' system could exchange enough geothermal energy to the heat transfer lines.
    (2)Will the heat transfer lines could conduct enough heat transfer from HD to heat depot.
    (3) What is the value of removing drilling without need of extensive excavation?

    My system satisfies condition (1) and (2) leading to condition (3).

    Regarding the geology condition, the wet condition should be best in conductivity. I will address this issue with the bulkyness of the HD. By expanding width of HD by 100 % the available heat source will increase by minimum 300 % (2 power 2 = 4). So heat conductivity differerence in geology could be easily solved by proper use of adquate HD unit size and qunantity.

    First think out how much land the slinky system could save (80 ft length/ton) compared to vertical drilling (200-300 ft), you could image how much land you could save if you have slinky in continuous coaxial flow (3 ft diameter * 20-30 ft length). The problem here is how to move water inside the slinky in continuous coaxial flow.

    My system developed method of
    (1) the moving the bulky water with no water pump.
    (2) Employing secondary closed water passing through HD.
    (3) Employing 'DX' like system.

    I hope it help your understanding,

    Sam, so far nothing you have said here or what I have read on your website has helped my understanding.

    Since you patent is in place, why don't you just tell us in simple terms how your system works.

    The following is how the tube size help on geothermal heat exchange.
    Geothermal heat exchange with convention loop uses 1-2 inches of pipes to conduct geothermal heat exchange. The distance of geothermal heat needs to to travel is minimum 1-2 ft length with continous run. So, change in tube size to 2-4 inch does not make big differences since the geothermal mass acquiered by increasing 1 inch of tube size is minimal (25.1^2/(25.0^2) that requires much more horse power of water pump to reduce efficiency.

    If tube size is 2 ft compared to one inch the additional geothermal mass would be (48^2/24.1^2) equals 4. In such a way by increasing tube size (HD) size there are proportional increase in available geothermal surface.

    See also that uses geocolumn, which may help you understand more.

    It takes time to understand and this is different concept than conventional ones.

    Sorry I had your name wrong. The site that you posted a link to has nothing to do with geothermal??

    Sorry, the website is GeoEnergy Enterprises, which uses DX system.
