The lagoon is fed by the water output of the nearby geothermal power plant Svartsengi and is renewed every 2 days. Superheated water is vented from the ground near a lava flow and used to run turbines that generate electricity. After going through the turbines, the steam and hot water passes through a heat exchanger to provide heat for a municipal water heating system. Then the water is fed into the lagoon for recreational and medicinal users to bathe in.
Iceland – the land of fire and ice. Situated on the boundary between the Eurasian and North American Plates, it’s defined by its dramatic landscape with volcanoes, geysers, hot springs and lava fields.
On this short trip I only managed to see the South-Western corner and definitely want to explore more. However I did see the Northern lights!
