In this episode, I spoke to Dr. Choi, a Korean gentleman, volunteer, and philanthropist with Ph.D. in solar energy at The University of Arizona in Tucson who lives in Tanzania and has been teaching young people in Tanzanian rural areas how to make a solar lamp of appropriate technology for the last 10 years.

 Dr. Choi talked about 

Why he gave up his US passport to leave his family in the US and moved to Tanzania 10 years ago.

What is appropriate technology and why it is important to teach local people in rural areas how to make a solar lamp of appropriate technology? 

Difference between his Kuku solar lamp and Kuku solar phone charger and commercial solar lamp

Why the name of his solar lamp is KuKu and how he set the price of his solar lamp at the price of one chicken  (=the price of his solar lamp)

His family believes that his decision to give up a US passport and find an opportunity to help and serve people in Tanzanian rural areas with a solar lamp came as a calling from God. 

His plan to work together with KOICA to launch more systematic and large-scale projects to help people in Tanzania. 

His African dream to distribute to African rural areas more various solutions of appropriate technology
