This summer, a first-of-its-kind global research expedition followed up on that surprise. Drilling for fresh water under the salt water off Cape Cod, Expedition 501 extracted thousands of samples from what is now thought to be a massive, hidden aquifer stretching from New Jersey as far north as Maine.

It's just one of many depositories of "secret fresh water" known to exist in shallow salt waters around the world that might some day be tapped to slake the planet's intensifying thirst, said Brandon Dugan, the expedition's co-chief scientist.

"We need to look for every possibility we have to find more water for society," Dugan, a geophysicist and hydrologist at the Colorado School of Mines, told Associated Press journalists who recently spent 12 hours on the drilling platform. The research teams looked in "one of the last places you would probably look for fresh water on Earth."

Good News: You've got a new source of fresh water.

Bad News: Extraction will cause groundwater-related subsidence of the nearby shoreline, causing rapid erosion and lower elevations. Multiple shoreline properties may be lost.

    Multiple shoreline properties may be lost.

    Depending on the area, I don't think I'm going to care much about some rich millionaires' second homes being destroyed. Sure, I don't want to see the erosion and decay of the landscape, but, you know...

    You can also kiss goodbye to the beach, too.

    We will make new beaches. With cocaine, blackjack, and hookers. In fact, the beaches will all be pure Bolivian cocaine, as fresh and crisp and clean as the driven February snow. We shall fiuck on the beaches, we shall fuck on the landing grounds, we shall fuck in the fields and in the streets, we shall fuck in the hills; we shall cum, and cum, and cum.

    Don't worry, scientists. There's a world that's thirsty for you, just waiting to be tapped. Go forth, and research! It's the end of the world, after all! Get in!

    There's a lot of people in these comments who seem to think energy is free, and reverse osmosis is magic.

    Reverse osmosis takes a ton of energy, and creates brine as a byproduct, which is difficult to get rid of.

    There are already lots of viable strategies for getting rid of brine, they are just more expensive than the naïve approach of having a big pipe on the shore spewing it into the ocean. Diluting it with seawater seems to be the most viable right now.

    I wonder if something like a 10 km underwater pipe with small holes in it that only let out a little bit of brine at a time would work. Might be a hassle to lay, at least to start, but I think that once it is in place it could operate without maintenance for decades. And piping is not really that expensive. Perhaps there are already researchers studying it, or it has been proven to not work. It seems like such an obvious idea.

    There was an article the other day about a new plant in Japan that takes the brine from a reverse osmosis plant, and reverse osmosisizes [?] it again back into treated waste water to generate electricity. As I recall, it's not full scale and meant more as a test/demo/proof of concept, but apparently it works ok for a first attempt.

    Brine and fresh water. Costs energy to separate, makes energy letting them recombine.

    No. My memory is that the English language article was a bit unclear on the details and had several indications that the author didn't actually understand the technology, but someone said a Japanese language article did a better job of explaining it.

    Brine and fresh water doesn't make any sense, because you're spending energy to create fresh water with the brine as the waste. Just turning around and recombining it to make evergy again is stupid. You can't even get back as much energy as you used to make the fresh water.

    But, spending the energy to create the fresh water, letting people use that water as normal, collecting their waste water as normal, treating the waste water as normal, and then, instead of just dumping the treated waste water into the sea, recombining it with the brine to make energy makes a ton of sense.

    Billions of dollars to get to it when they could install a desalination plant >.>

    Why are we like this?

    Because desalination is incredibly energy intensive, that's why.

    The world doesn't run on renewables. If the energy mix contains even a bit of fossil fuels, then any extra demand props up fossil energy that could be shut down.

    I’d also like to point out that when you say “the energy mix” you’re not meaning the energy mix used by this project.

    If any of our energy is from fossil fuels then increasing the use of energy increases the use of fossil fuels. Even if a new project uses 100% renewable energy it will increase the amount of fossil fuels used until we’ve eliminated them completely.

    Because they're academics and actual direct usefulness isn't that important. A plausible-sounding story to get a grant is good enough. And then phys.org publishes it uncritically because they're phys.org.

    Cool. Come talk to me when finding water is hard, as opposed to just shipping a sufficient quantity to wherever you need it.

    If there's a spot where a major center is next to one of these and nothing else, I suppose it could have a niche. I'm guessing the microbes and geological history are the main thing they're excited about, though.

    Man... I learned how to boil salt out of seawater in the boy scouts. You'd think we could just do that, but at a larger scale.

    Just accelerate the entire universe evenly, nothing gains kinetic energy relative to anything else, the change is undetectable and the energy used to accelerate everything is so iretrivable you can't even prove it ever existed.

    If you heat it to many times it's boiling point, sure.

    Has it occurred to you there may be a good reason this isn't done at scale already?
