I first thought this was a piece of architecture rescued from a minature golf course. Something like the old troll's house on the 16th fairway.

It's actually from an old wind turbine, says Barry Johnston, CEO of ScotRenewables, a tidal power company in the Orkney Islands. ScotRenewables is building an unusual tidal turbine that sits on the surface of the water. It is somewhat of a can-do company. The employees -- mostly mechanical engineers and hydrodynamic specialists -- built their own office building and 40 meter wave tank, along with this wind hub room. Johnston first tried to use it as a conference room but each time the speakerphone was used it echoed like crazy.
