A few weeks ago, on a trip along the Frinton seafront in Essex, I noticed some strange structures out to in the North Sea. They were barely visible on the horizon, but looked across between towers and ships. It turns out that they were ships erecting towers - for a windfarm. For what it’s worth, I think they added interest and focus to the horizon, which, let’s face it, is otherwise just a line obscured by mist.
