Ocean found 400 miles below earth's surface.

LOL! hahaha! I know, crazy idea and "thinking outside of the box". But, I actually majored in math and minored in physics in college. Water pressure is a potential energy source that's "just there" waiting for us to harness. And, there is a Norwegian company, that I just found, who is working on doing so. Here's an article:
http://oilprice.com/Energy/Energy-G...-the-Bottom-of-the-Ocean-to-Store-Energy.html

And another article, not exactly using ocean water pressure but water pressure in general :

Both articles are about systems to use stored potential energy that was put into a system by humans.

There is no energy in still water.

In hydraulic system calculations the fluid has "head", pressure , velocity and elevation. These are conserved . At the surface of a free body of water there is zero "head", no energy, as you descend pressure goes up but elevation goes negative to balance precisely at a big fat ZERO.

Temp and pressure of any free water 400 miles down would turn into a geyser of steam more like plasma than water.

I'm curious to hear more details behind your opinion, is this a subject you're familiar with? What's wrong with the science?

If I read the article correctly the water is not posited to be 'free' but embedded in a mineral rock called ringwoodite. Is this not plausible?

Here is the original article from the journal 'Science':

I believe downunderwonder is referring to the general news reports, not the original article. The original article was a theoretical treatise: based on seismic wave data, and some lab simulations, the authors proposed that perhaps water molecules could be embedded in the ringwoodite. Bear in mind that this is 400 miles deep, and the only actual data we have about anything 400 miles deep, is the seismic wave data.

Somehow the news reports twisted this theoretical proposal into a story proclaiming "Scientists have discovered an ocean of water 400 miles deep!" No, we have taken the seismic wave data, and run some lab simulations, and proposed a hypothesis that may match the seismic wave data. That hypothesis is water molecules existing in the ringwoodite, hardly "massive oceans".

Fair enough, but none except the stupidest referred to an ocean as such (Headlines are idiotic as a rule, and usually not even written by the journalist themselves).

I have not seen any debunking of the science, if it is plausible it represents a massive amount of water.
