I have worked on health and healing centerwebsite which i used to develop the user interface.

This is project is specifically aimed at areas and conditions of the world where water supply is less and access to clean drinking water is sometimes at long distances. A pedal operated water filtration system is a water filtering apparatus which can filter water by using human muscle power via a pedal operated mechanism. this apparatus is preferably mounted on a bicycle for increased portability.

This project is specifically aimed to areas where air supply is more. Natural ventilation, also called passive ventilation, uses natural outside air movement and pressure differences to both passively cool and ventilate a building. Natural ventilation is important because it can provide and move fresh air without fans. For warm and hot climates, it can help meet a buildings cooling loads without using mechanical air conditioning systems. This can be a large fraction of a buildings total energy use
