    Default thermal mass heating and cooling

    Way back in the olden days there was a movement to passively heat/cool a house using underground thermal mass of the soil itself. The process was sometimes called "cool tubes".

    By constantly changing the air in a house over a 2 hour cycle the house was supposed to be kept in a median temerature range.

    But 20 years down the track cool tubes seem to have died out, is there any modern info available?

    Perhaps not quite the same that you are talking about, but geothermal heating/cooling is slowly taking off, particularly in the US.
    There are a couple of projects here in Australia:

    I did a lot of reading on this subject before I built our house in an effort to avoid the wood heating scenario, in the end it got all too hard, I now burn wood!
