Turbines on a Wire
Existing power lines could become home to wind turbines thanks to a design concept from Victoria University in New Zealand. The design takes a series of spiral wind turbines and places them onto power lines, generating electricity through electromagnetic induction and putting that energy right back into the power grid.
Electromagnetic induction occurs when a wire is moved through an electric field, which then causes a change in the conductor. This forms an electromagnetic field, to which the electrons will move to the other side. The protons remain stationary as electricity is created.
The turbines will be placed horizontally onto the wires, having the appearance of very large pinwheels. The advantage of placing the turbines horizontally is that they will be able to handle much higher wind speeds. These new wind turbines would eliminate the need to build large structures, as they will already be using the bases of the existing power lines.
