A natural approach
China DailyA 12,000-square-meter area of land on Shanghai's Chongming Island has been transformed dramatically by Xiong Feng into a farm with a rice field, a lotus pond, pavilions, boathouses, docks and secluded corners where visitors can spend their leisure time close to nature. While many people have been cranking up their air conditioners to deal with the ongoing heat wave in Shanghai, Xiong Feng and his family have managed to stay cool without having to use any such device. Dubbed the "rice field theater", this structure was designed to draw cool air from the surrounding fields while allowing hot air to rise and dissipate through the hole at the top, according to Xiong. Unlike other farmers who often use air conditioners to beat the heat, Xiong relies on a row of ball-shaped stainless steel roof fans that have been strategically positioned so they spin due to the influx of air from outside the "camp".
