A somehow new idea let us have cool air for the electricity consumption of a simple fan.

Just add water and ice cubes or similar from time to time and the air gets cool.

Preferable for rooms up to 20 sm and in a rather dry environment, price around euro 100,- in quantities and ....it really works !!

The unit comes on rolls and is about 80x60x40 cm needs only a plug just like a fan.
