Love this article, but they kinda bury the lede making the Coca-cola joke about bottling and selling water.
Most bottled water you buy in stores is, in fact, tap water. If you think they’re getting it from a mountain spring, even if there’s a mountain on the label, you would be mistaken. You wouldn’t want mountain water (with bear piss) anyway, the water you buy bottled is filtered and treated. It’s good tap water, but it’s still tap water. So next time your water bottle runs out, just refill it from the tap. Assuming your tap water is potable and doesn’t taste like shit.
I grew up drinking mountain spring water. It’s way better than “bear piss”. Filtered and treated doesn’t mean better. Some natural water from springs is perfectly fine.
Why is it necessary for the water to go up and down to turn the turbine? Isn’t the pressure already added to the water and you can directly use it to drive a heavier turbine at ground level?
Second, as you can probably guess by looking at the above picture, pumping the water up 40 meters with water pressure and then back down doesn’t accomplish anything—you can just hook the faucet up to your device, and let the water pressure drive the generator directly.

And here I thought I was being clever. Thanks for sharing! That was great.

I am DELIGHTED

That’s only correct if it’s labeled as “purified water.” If it says “spring water,” then it came from a mountain spring.
The thing about being bottled at the source, is that it’s upstream from all the “bear piss.”

He says all mountain spring water is bear piss. I say some is good. You downvote. classic fediverse.
I definitely want mountain water, it’s delicious. 100x better than any bottled water.
The flavor is E. coli
Wow. I never thought of bottling and selling water.
Was surprised xkcd didn’t mention steam boiler turbines.
ah. yes. the nestle way.
What does that have to do with water pressure? In that system, the energy comes from the heat.
True – it would require a external heat source (wood, gas, coal, concentrated solar, etc) to boil water for turbine generated electricity.
