Digestible Gulf Stream - 2008

"Here, two horizontal metal planes are extended at different
heights. The lower plane is heated to 28°C, the upper one is
cooled to 12°C. Like a miniature Gulf Stream, their position
creates a movement of air using the natural phenomenon of
convection, in which rising hot air cools on contact with the
upper cool sheet and, falling, is then reheated on contact with
the hot sheet, thus creating a constant thermal flow, akin to
an invisible landscape."
