a large number of people in developing countries suffer from a lack of access to electricity and safe drinking water. mexican design consultancy NOS have created ‘photoflow’ a product designed to collect these precious natural resources and to help distribute them to the masses. most developing countries are located near the equator and they receive more sunlight and rainfall than other places, however these basic amenities are not easily available. ‘photoflow’ aims to solve this issue, building upon the designs of existing rooftop containers, the simple device is made from recycled materials and composed of eight identical triangular photovoltaic modules that are mounted on commercial or custom water tanks. assembled together they form an octagon with a slight slope of 3 degrees, which allows water to funnel into the central filter. the water path then continues through a hose that directly flows into the water tank.

 

each module is equipped with first-generation monocrystalline silicon solar cells covered with an anti-reflective adhesive to protect the photovoltaic semiconductor and minimize the loss of light through reflection. the system integrates an N-type and P-type silicon layers. on top of the outer layer of the glass a nano repellent film is applied to prevent dirt from obstructing light. the water tank is made of recycled polyethylene through rotational molding with a capacity of 400 liters. The inner layer of the tank is covered with a coating that controls the formation of bacteria and fungi to maintain the quality of potable drinking water.

designboom has received this project from our ‘DIY submissions‘ feature, where we welcome our readers to submit their own work for publication. see more project submissions from our readers here.

  • Excellent idea. Call Bill Gates – now. …then design a 2 bedroom structure under it for rural areas. It would be great for rural Cent. Am. Bravo Agustin.

  • Can the house carry the weight of a full tank?

    David Mackitnosh says:
  • In Vietnam the costs of a solar panel installation to supply one average household is ten times their annual income. In this country even the rich do not use these solutions because long-term strategies has no place in their philosophy.

    Airborne says:
  • This is a very good idea of storing natural resources. This is an awesome idea.

    Rhinogutter says:
  • WHERE CAN I BUY THIS SYSTEM???
