This project’s purpose is to enable buildings generate their own electricity and to save water. Two systems are placed on the roofs of the buildings. The building produces its own electricity with the solar panels in sunny days and the wind tribune in the garden helps to increase the electricity production. The second system is the roof gutter pipe system that is activated in rainy days. The funnel-shaped cover system on the pipes opens and closes to collect and direct the rainwater to the waste-water treatment system built underground for purification. Thus, water is stored for use later. Additionally, a smart robot is designed to collect the snow and send to the treatment system. Finally, we also can prevent radiation by planting cactus for each building.
