Zambia Friends in Lusaka, Zambia’s capital, convert reusable cooking-oil buckets into self-heating water buckets by adding heating elements. During winter, the group buys the buckets for 20 kwacha ($2.26) each and the heating elements for 70 kwacha ($7.92). They then sell the final product for 120 kwacha ($13.58).
