Venice Architecture Biennale 2010: Japanese studio Tetsuo Kondo Architects and environmental engineering firm Transsolar have suspended a cloud inside the Arsenale exhibition space at the Venice Architecture Biennale.
Called Cloudscapes, the installation is created by pumping three layers of air into the space: cold dry air at the bottom, hot humid air in the middle and hot dry air at the top.

A spiral walkway guides visitors up through the layers to emerge above the cloud, before they descend back down through the vapour to the floor.
The Venice Architecture Biennale continues until 21 November. See all our stories about it in our special event category.
The information that follows is from Tetsuo Kondo Architects:
Creating clouds indoors is only possible through climate engineering, by applying physical principles at the building scale.
By replacing pressure differences an temperature gradients in the atmosphere with mechanically controlled heat and humidity, the air in Cloudscapes is divided into three distinct layers.
