One more month, and the World Expo Shanghai 2010 will open its doors. China’s actual meteorological situation reminds us, that weather has always been a rather unpredictable phenomenon. However, it is a fair prediction to say, that the World Expo will experience some hot and busy days.

To ease the visitors’ journey, the World Expo is turning to water mist. A system of outdoor tiny water mist sprinklers will be installed on strategic sites of the expo area. The evaporation of the water mist has an endothermic effect, which results in a drop of temperature.

According to Wang Junfeng (王军锋), vice dean of the Energy and Power Engineering Faculty (能源与动力工程学院) of the Jiangsu University (江苏大学), where the technology was first developed, this system can locally make temperatures drop up to ten degrees centigrade. Furthermore Wang says it is very energy savvy and doesn’t emit any pollution. It was already put into use at the beach-volleyball site of the Beijing Olympics in 2008.

TTC Rubymist, a company specialized in these kind of equipments that can also be used for esthetic reasons, will equip many of the expo’s pavilions as well.
