The first seven days in Dar es Salaam, Tanzania, are accompanied by a seminar. It includes another introduction into culture, politics and language performed by a Tanzanian teacher. In the afternoons the volunteers discover together the city and try to live through some everyday activities like riding the bus, negotiating prices on the marked and having first conversations with Tanzanian people. The volunteers visit NGOs and companies who work in the domain of renewable energies. There they get in touch with Tanzanian actors. On one of the last days of the seminar the volunteers move freely through the city in small groups to participate in a city rally with different tasks.
