One of the great causes of poverty in developing countries is the lack of access to education and clean drinking water. To address this problem, Ecosolar International Inc.or ESI, a registered 501 (c) (3) non-profit organization, was formed in 2007. The purpose of Ecosolar is to help the poor break out of the cycle of poverty in focusing mainly in clean water, healthcare and education opportunity. Our group is made up of individuals of many years of experience and training in the areas of water filtration, healthcare, education, photovoltaic solar, and electronics.

We currently offer WHO (World Health Organization) quality clean water systems to low income communities in Vietnam and in other parts of the world in the future. As for the education, we are working in improving the learning environment by providing schools with microscopes combined with computers; we have also assisted students with college scholarship search, learning English, soft skills and leadership skills in order for them to get a better education overseas and to pursue their dreams in life. Our microscope project also helps health professionals save time and be more effective in their diagnostic tests in hospitals. We have promoted the idea of volunteerism and community leadership development among students by encouraging their involvements in the activities in clean water, microscopes and education. We plan to grant scholarships to underprivileged students, encouraging them to continue their education amid many difficulties facing them in their daily lives.

Since Ecosolar’s inception, we have achieved: (a) built and donated more than 35 water stations to provide WHO quality water for drinking and cooking and clean water for daily uses to schools and hospitals in Vietnam; (b) built and donated more than 1000 microscopes with computers to schools, hospitals and laboratories throughout Vietnam and (c) we have assisted more than 70 Vietnamese students to study abroad; many of them with scholarships and have finished their undergraduate and graduate studies from colleges and universities in Japan, Europe, Australia and mainly US.

Nang Tran

A McKnight distinguished visiting professor and a teaching professor at University of Minnesota, Nang Tran received his PhD in solid state materials and device physics from Osaka Prefecture University-Japan in 1979 and did his postdoctoral research at Harvard University and University of California, Irvine. Nang had spent 28 years in industry, working on solar cells, transparent conducting oxides, medical electronics and data storage. His main technical achievements are : (i) co-inventor of a direct x-ray digital radiography detector, a major medical breakthrough for digital mammography (1990) ; (ii) co-inventor of transparent conducting ZnO film doped with group III elements (1983). At present, most of the commercial thin film photovoltaic solar modules have at least one layer of this oxide in the device configuration. He has received more than 62 patents and many awards including the prestigious R&D 100 (100 best products of the year worldwide, 2 times) , Photonic Circle of Excellence (25 best photonic products of the year worldwide). In the last eight years, Nang has been working with Ms. Lan Le and Mr. Viet Nguyen on many non-profit activities which include WHO quality water systems, microscopes, solar electricity and helping students to continue their education overseas.
