From "A watershed moment," by Gaynor Aaltonen, in the July 10/July 11 2010 issue of the Financial Times:
Legends seep through the area and one maintains that Kerr's house stands on ley lines and therefore has the "right energy".
The article is about a man who has installed a personal power plant at his family home in Alhampton (in Somerset) using the technology of the Archimedes screw. Apparently the British government's Environment Agency calls the screws "pescalators", because they are "fish-friendly". I wonder how, exactly.
I don't know that I would set ley near key.
