I dare turn the thought around - empty conductors with some coolant coursing through them, could be utilized for transprorting a high current. Also, this is basically done in spot welders, where the welding heads have water channels inside them for this very reason.
Yes. BUT why would you want to do that when the metal wire is a much safer and efficient way for electric power transmission?
Hey there I am Laura Avila Barraza Working as a powerhouse electrician.
Water has a much greater electrical resistance than copper, which means it would cause a large reduction in voltage after long pipes filled with water.
I think this is the main reason,:
Water pipes can leak if broken
If a water plastic pipe breaks, dirt can penetrate, resulting in zero or less good conductivity.
A copper cable always has a certain diameter which is fixed, with water it depends on the pressure of the tube.
The pressure is necessary to keep the water at a pressure that does not leave bubbles.
The water can freeze, which can lead to several conductivity properties.
You need more pipes, if a pipe breaks, the possibility is that the water will "mix", causing a shortcut. A clean cut of copper wire will not directly cause a shortcut.
