Live in a Hot Place, See How to Keep Yourself Cool using a Natural Air Conditioner System

A great number of people around the world live in very hot zones. Out of these people a significant number cannot afford to keep themselves cool. To these people you can not even talk about such luxuries we take for granted: electricity, internet, running water, or even regular supplies of food and clean water. The unbearable heat of summer temperatures in some of these places is crippling. But their situation is not without hope!

More than 28,000 people live in a tiny area called Daulatdia in Bangladesh. They are cramped in small huts with no running water and temperatures outside and inside can rise above 113º F.
