The city of Ulm, which is about 120 kms from Munich, has taken a big step in showcasing the future of shelters by installing sleeping pods at several locations in order to protect the homeless from the cold during peak winters.
The city administration has installed durable sleep cabins that are made of wood and steel. They provide protection from rain and cold and are big enough to accommodate two people inside. Impressively, they can also circulate fresh air.
The shelters are fitted with solar panels to provide power. There is also a radio system inside them to enable people to communicate even if they don t have a cellphone.
