My wife has been complaining about the hot weather so I put together this 'evaporative air cooler' for her using a plastic storage box. Along the broad front side is a kitchen extractor fan and along the broad back side is a grid of 50 x 6mm holes. The 3 plastic containers contain ice bought from Iceland in 1 kg packets. The lid is on the left and will be sealed in place on top with decorator's tape. In use the top, bottom and left and right hand short sides are wrapped in a dust sheet to insulate the box (-of course not the front and back). It's not that energy efficient or economic but it has stopped her complaining about the hot weather today - a result then! It is not a solution for the long term just while our air conditioning is out of action today and tomorrow.
(There is a grille - not shown - over the fan impeller but I forgot to put it on before taking the photo.)
