I think the difference is that water lines for irrigation are mostly aerial except for the one spot where they enter the ground water source. Further, the lines themselves don't move, the machine holding the lines moves. Finally, there is a substantial difference in 'I have a small water leak' and 'I have a small power leak'. Maybe I'm being too closed minded, but I can't see that working long term. The stresses of being dragged around the field, or the infrastructure required to hang the power cord overhead would just be outlandish. For some reason, I can't get the picture of a powered grid of wire mesh over a field like giant bumper cars.
