This video on new pylon designs misses the option of putting the cables underground (or underwater) instead. This would have a higher up front cost but lead to much better looking countryside and probably lower total cost of ownership.
The lower total cost of ownership was the argument Dr Liam Fox (Defence Secretary) used in his recent objection to a scheme to place new pylons in his Somerset constituency.
If we do have to endure yet more pylons, I’d vote for the sail design, “Plexus”, by Amanda Levete Architects & Arup, shown in the attached photo.
