There are Disaster-aid vending machines in Japan. When Japan was struck by earthquake in 2011, it saw many blackouts and power shortages.
Many people did not have water to drink and these machines served as a source of drinking water for many of them. In many places, vending machines were installed to help people survive disasters by offering services such as providing drinks, food etc. for free and displaying emergency information.
These wonderful machines can also be used as electricity source during a disaster. They also have a reserve power source, which can be used in case of power cuts, and can be operated remotely.
