Cooling tower

This is a kind of giant inhaler, built from natural materials - wood.

At the bottom of the structure there is a tank with a salt solution. Water under pressure is fed upwards through natural obstacles, the streams break on the branches and fall around with small rain, saturating the space with useful vapors. That is why the air here is saturated with iodine, potassium, and magnesium. One hour in a cooling tower is equivalent to 3 days on the sea coast.
