Would You Swim In Power Plant Wastewater?

    Normally, the answer would be no. But in these very limited circumstances, at Iceland's Blue Lagoon, you can swim in geothermal power plant wastewater, and it's even healthy: although the marketing material doesn't usually mention it. Here's a story about geothermal energy, cheap heat, and how to keep some ducks warm.

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.

The Canadian Government commissioned a survey of the nations prospects for geothermal energy production. The assessment found that Canada has enough geothermal resources IN GROUND ( as opposed to that needing drilling to access, which has it's own environmental consequences) - to provide ONE MILLION TIMES the nation's energy requirements. This study's release was delayed for nearly a decade, but after it's release the Canadian government nevertheless moved into intensive Tar-Sands extraction despite this bountiful clean resource.

I swam in the Blue Lagoon (hella expensive) and then I realize now that it wasn't a natural geothermal pool? One of the signs I read inside the lagoon said it was 1 of the 7 wonders (I've been to 2 not including this) and so I immediately thought this was connected to all the other geothermal pools in Iceland hence it's named the land of Fire and Ice or something along those lines. THEN YOU COME UP HERE AND SAY I WAS SWIMMING INSIDE WATER FROM A POWER PLANT???

I've been in the Blue Lagoon and I can attest: It's nice and relaxing and the look is quite unique. As for the marketing the story I heard was that the workers of the powerplant went swimming in the water and found it to be really nice...and then some smart people decided to market it as a spa. And yes: The earth would most likely run out of heat eventually...but it will probably be swallowed by the sun before that.

The waste water from a coal power station is not the water that was used to produce steam to spin the turbines. That water is very very clean and largely remains in a sealed system. The water at the bottom of the cooling tower was used to cool the sealed system, but doesn't come in contact directly. Generally the water is taken from a nearby river and when it's put back after use it's a lot cleaner than when it was taken out (and obviously thus gas to comply with strict regulations). It's been known for the warm water to serve other purposes before returning to the river, for example used for an eel farm! Another enjoyable video and I was happy to hear you on the no such thing as a fish podcast last week

Ok, when a guy from the UK says a place is "a bit wet" that needs to be taken seriously.

How often must Tom get asked for help or advice. Like doctors who get asked about what to take for pain or mechanics who get asked about car problems. Tom must be driven crazy by everyone's constant questions for help.

100 IQ : dump geothermal wastewater into the sea. 200 IQ : using geothermal wastewater as nature water reserve. 2000 IQ : Charge 30 Euro so people can swim in it.

"Cold reservoirs will heat up soon enough". Geothermal is big in the Netherlands for the heating of greenhouses although it's low temperature. A 1km deep well may produce water from a triassic sandstone at 30° or so for example. Interestingly, dynamic modelling suggests that once cooled after a couple of decades of production, the reservoir may take 300 years to recover its temperature.
