The Trombe-Michel wall is a passive solar heating or air conditioning system working on air circulation. In front of the wall, there is a glazing trap collecting the heat of the sun and spreading it to accumulate in the walls. Implemented and tested by Professor Félix Trombe and architect Jacques Michel, this device takes advantage, by greenhouse effect, of the free energy of the sun.
Based on an original idea of the American naturalist Edward Sylvester Morse of 1881, the concept is now taken up by a team of young engineers from central Lille under the name Enar. The wall made of cans recovered, cut, then assembled, recreated the action on the air described by Morse, Trombe and Michel, at a lower cost and in a D.I.Y way.
