    Um Elektrizitt (oder hohe Wrme) zu erzeugen braucht man im Untergrund, mglichst oberflchennah:

    1) Hohe Temperatur:

    2) Hohe Durchlssigkeit:

    3) Viel Flssigkeit:

    Energie

    Energie Transport (advectiv)

    Was heisst oberflchennah?Hngt ab von:

    1) Nutzung (Strom oder Direktwrme): Strom (mit Wasser): >100oC(besser >180oC)

    water can flow primarily through the (about parallel andhorizontal) pathways of highest permeability. Thus themean horizontal permeability is given by the arithmeticmean [Maasland, 1957]

    kx 1

    N

    i1kxibi; 42

    where the subscript i denotes the ith layer or pathway, bi isthe thickness of layer i, and b is the total thickness of alllayers.[44] In contrast, vertical groundwater flow across hori-

    zontal lava flows (or aquifers) is passing through sections ofvarying permeability in series, so that mean vertical per-meabilities are typically determined by the harmonic mean[Maasland, 1957]:

    where kz is dominated by the lowest permeabilities alongthat path. Hence in volcanic or sedimentary settings, whereslope-parallel, and thus approximately horizontal, layers,

    pathways, and aquifers are common, typically 10 % kx/kz %1000, at least near the surface [e.g., Deming, 1993] and inthe absence of nea
