The technology to make this pool possible has a worldwide patent. Essentially, it collects and filters water from the ocean, maintaining a temperature that’s up to 9 degrees warmer than the ocean water (in the Summer of course). Fischmann, the chairman and founder, is a biochemist by trade and came up with the technology to allow for ‘lagoons of unlimited size’ with crystal clear water and drastically reduced costs to typical pools.
The company estimates construction costs at approximately US$ 400,000 per hectare (US$ 160,000 per acre) for a standard 5 hectare (12 acre) lagoon (excluding earthworks and related work) and maintenance costs of approximately US$ 4,000 per hectare per month (US$ 1,600 per acre per month) including energy, labor and additives.
