Is it feasible? No, because the size is likely to be a few kilometers of ungrounded wire, which is not exactly a cheap solution.

Is it possible? Yes, there is clearly a voltage gradient at which point how much energy can be harvested is a matter of size of the antenna we use. Now, a house consumes about 100,000 times more power (kiloWatts). These are relatively small currents, and correspond to a 15 milliWatts (≈1.5 × 10 -5A × 10 × 3V) for every meter of ungrounded fence.

This is a theoretical calculation so take it with a grain of salt. |I shock| = 15.4 × 10 -6 amperes/meter or 25 milliamperes/mile Line of the 345 kV transmission line, Figure 111-1, and a phaseĬonductor vertical clearance of 29 feet, reference 12) then fromĮquation 111-3 the magnitude of electric shock current is: (maximum gradient for a lateral distance of 38 feet from the center Inches (3.2 × 10 -3 meters) and a ground voltage gradient of 4 kV/M One of the major risks (or opportunities to "generate" power) is when building fences parallel to high-voltage power lines.įor typical fence values, h = 4 feet (1.22 meters), GMR = 0.125 Lighting a neon bulb is one thing, but how much power can be generated? This was studied multiple times, for example in 1976 by the US Department of Agriculture. Ungrounded metal wire fences can also receive sufficient charges to cause nuisance shocks.

Backyard metallic objects such as swings, portable grills and lawnmowers have been known to deliver similar shocks. Larger objects such as a building or a large vehicle have the capability of a larger charge and therefore the shock could be more noticeable. The closer the conductor is to the ground, the higher the field strength beneath it tends to be, and the Higher line voltages produce higher electric field strengths. This effect can power stuff.įor an example of this, see this (awesome) picture of a neon being lit by proximity to the power lines.Īlso, this energy leakage is openly admitted by power lines companies, for example:Įlectric fields emanate from any conductor or wire that carries voltage. There is a vertical voltage drop from the wires to the ground. It is certainly possible to "harvest" power via induction from high voltage power lines.
