In the rural village of Mhasawad, many residents regularly drink water with salinity levels of 1,200 ppm (parts per million), double the levels recommended by the World Health Organization. Water with high salinity levels can cause countless health problems including kidney stones and digestive problems, and taxes the energy grid. But for many, purchasing treated water can cost upwards of 30 percent of one’s monthly salary. At the beginning of this year, we traveled to several rural villages to meet with farmers and villagers to better understand the problem. Back at MIT, we are now developing a cost-effective solar-powered desalination system to provide a safe and affordable source of drinking water. This is not just an engineering problem—we are operating as product designers, ethnographers, social scientists, and machine designers to test our assumptions and build a lasting solution. Ask us anything!
