Makoko is a floating city in Lagos, Nigeria. This is an orphanage/school. The floating city has no infrastructure, No electricity, No public services, No sewage or trash service. The children often bathe in the water and use the water for cooking that they also poop and pee in. Typhoid and Malaria are rampant. There is one American who lives in the slum trying to use water catchment drains on his hut, And solar electricity to power his computer. Looks like they have lots of water for bitcoin transactions.
