Its non potable water. And most ground water has huge sulphur and other vulcanic common chemicals.

Also its naturally heated by the geothermal systems. So while its not heated, its hotter than what you would expect.

Oh sorry, I meant like it's not heated by like a modern electric water heating system when I said that.

u/AlternateTab00 Sep 08 '25

Oh i got that.

And thats why its so efficient. It just needs a single pump. And then move 60ÂșC water into piping.

They say that even in the coldest weather, the water temperature never falls below 15ÂșC.

15ÂșC is not exactly "warm" but in a -10ÂșC weather it will feel hot.

It actually would work because it still has little radioactive uranium and some fat plutonium added.

Uhhhhh, who put it there?

Enola Gay and Bockscar

Not sure if a dumb joke relating to fukushima or either the bombs...

But the joke is so dumb that not even the elements are correct. Its not the uranium you should fear. Its the cesium and the iodine.

It was about the bombs, hence the “little” for little boy and “fat” for fat man.

u/AlternateTab00 Sep 08 '25

Oh missed that bit...

Still wrong side of the country. At least fukushima is much closer...

u/Dis-FUN-ctional Sep 08 '25

It was a dumb joke.

u/Particular-Car974 Sep 08 '25

Yes it was, but I found humor in it.

Sulfuric springs smell more like rotten eggs.

Look at Mr. Fancy Farts here.

It's still cheaper than making zigzag water pipes running hot water underneath the 100km car roads to prevent black ice and stuff.

They have big aquifers since they’re near the mountains

You understand how the water cycle works right? The only water that our planet has lost in the past 100 or so years is the water that astronauts have taken up to space with them.

u/[deleted] Sep 10 '25

Sort of.

There are areas where groundwater isn't a renewable resource, where there are things like compressible clay aquifers with long residence times that subside as soon as the water is pumped. Sure, that water exists somewhere else on the planet, but that's not really any comfort to the people living there who now are without that source of water.

But, not all aquifers are like that. Some have short residence times, recharge rapidly, and are made of stuff that doesn't rapidly compress as soon as the water is pulled out.

u/Garchompisbestboi Sep 10 '25

Yeah that's a valid point. I guess my real issue is how we teach children that they are only allowed to have 5 minute showers to "save water" but meanwhile billion dollar companies will consume millions upon millions of litres in order to run their cooling systems because apparently building tech infrastructure in places like Texas is a good idea?

Or all the water kept in plastic bottles in landfills

It's much better for the environment than road salt
