1. A helical pile comprising:
a terminating extension shaft having a proximal end, a distal end and a cavity extending along at least a portion of an interior of the terminating extension shaft;
at least one shaft having a proximal end attachable to the distal end of the terminating extension shaft, a distal end and a cavity extending along at least a portion of an interior of the at least one shaft;
at least one helical load bearing plate secured to the distal end of the at least one shaft;
a first tube extendable through the cavity in the terminating extension shaft and into the cavity of the at least one shaft a first predetermined distance;
a second tube extendable through the cavity in the terminating extension shaft and into the cavity of the at least one shaft a second predetermined distance; and
a mounting bracket assembly having:
a pile adapter including a pile receiving flange that can be mated with the proximal end of the terminating extension shaft, and a central aperture aligned with the pile receiving flange that permits the first and second tubes to pass through the pile adapter;
a bracket assembly having a mounting bracket capable of supporting at least a portion of a structure and at least one mounting plate secured to the mounting bracket and used to secure the mounting bracket assembly to the pile adapter; and
a bracket stabilizing assembly used to fix the orientation of the bracket assembly relative to the extension shaft;
wherein the cavity in the at least one shaft can be sealed except for the first tube and the second tube, such that when the helical pile is driven into soil, fluid can be circulated between the first tube, the cavity and the second tube so that heat can be exchanged between the fluid and the soil.
