Last night, I watched new ideas of Illac Diaz, a social entrepreneur, on how to preserve food and have lighting during typhoons and bad weather
1. DIY ref - Pot ref made from two clay pots, one smaller and other bigger than the other. The two are then sandwhiched with sand which are then wet with water. A layer of cloth is placed in the inner pot where fruits and vegetable can be placed. The pot ref can keep food fresh for 2 to 4 weeks.
