One thing I couldn't fit into my script: the pipeline expands by around several metres along its length when it's in use, because of the hot water running through it. The big boxes along the way are expansion joints and supports to allow it to move! As ever, all my sources are in the description.,(reply>), Uranium isn’t dangerous,(reply>), Hi,(reply>), i have been to all the places in this video,(reply>), @Nitidus generally you don't drink the warm water. You can, and it won't hurt you, but it has a... taste. In some places people have started using heat exchangers to transfer the heat from the geothermal water to plain cold water as the geothermal water tends to be rather rich on minerals (that means it can dry out your skin).<br><br>The majority of the population does not drink bottled water. But there are numb-nuts in between that would rather pay for tap-water on bottles, so we let them. It's the same (cold) water on the tap as in the bottle.<br><br>The geothermal water is used for house heating, showering, bathing, swimming pools, heating pavements, warming up greenhouses (think growing vegetables all year round)...<br><br>The only impurities that are dangerous to ingest are those that come with the wastewater of Svartsengi. But those impurities have instead shown to be extremely beneficial to those with Psoriasis and other skin problems, and thus - Blue Lagoon.,(reply>), @Þór Sigurðsson So do they filter the water in those other areas before drinking or cooking? Or do they only drink bottled water? Can it be used for showering at least or are those impurities dangerous enough to only use it for heating?
