In a recent post, we highlighted 5 places around the world that man has put together for the awe and enjoyment of our species. Usually this is nature’s job, but some of the achievements of humans are particularly noteworthy. Besides their alluring features that attract droves of people from all over, some of them are championing technologies that are cost-effective and ecologically sound. Iceland has made use of that very technology to bring the world Blue Lagoon.
Iceland is known across the globe for several features, and one of them is its geothermal pools. Its steaming natural waters combined with the high prevalence of salts and minerals due to volcanic activity, and you’ve got a day of detoxifying relaxation ahead, soaking up all the earth has to offer you. Would it change your perception to learn that the water you’re luxuriating in is the by-product of a nearby power plant?
If it helps to imagine this scenario, it is a geothermal power plant, which means it extracts superheated water from beneath the earth’s surface to operate a turbine that generates electricity. As it is extracted, it becomes mixed with sea water that seeps into the flow. The water is then recirculated to create energy for a nearby town, before it is sent through special mixing wells and cooled for use in the Blue Lagoon. Now structured to accommodate tourists year-round, it began as a natural reservoir in local lava beds. Although development has improved the usability of the lagoon, the surrounding landscape is all very natural, including the color of the water and its purported healing properties.
The remarkable blue hue of the lagoon is due to a particular type of blue green algae that inhabit the water. The healing properties are said to come from the lagoon bed itself — silica mud. Enriched with minerals and salts, this mud is used locally to treat a variety of skin disorders, and has been said to be effective for treating psoriasis. Commercial distribution of the silica mud has become more popular as those who seek beautiful skin hear about the wonders of Iceland’s Blue Lagoon, and treatments are available on-site for an additional fee.
The most amazing thing about this whole operation is the symbiotic, non-polluting methods chosen to operate systems that benefit many. The lagoon, which holds 6 million gallons of this repurposed sea water, is flushed with new water from the plant every 40 hours, while the lagoon water is flushed out to sea. The water used to create power is naturally occurring 6,000 feet below the surface, and the methods employed do not harm local ecosystems. No chemicals, no pollution to the sea or surrounding areas, all with a by-product of relaxation and refreshment.
Geothermal pools are found in places all over the world. Have you ever been to a geothermal pool?
