You don't need to travel 6.8 miles down into the Mariana Trench, like James Cameron did, to know that the deeper you dive under water, the more the water pressure increases. Heck, you probably found that out the first time you dove into the deep end of a swimming pool.

Now a group of Norwegian scientists from the SINTEF organization want to put that pressure to good use by building a power plant on the ocean floor.
"Imagine opening a hatch in a submarine under water. The water will flow into the submarine with enormous force. It is precisely this energy potential we want to utilize," Rainer Schramm, inventor and founder of the company Subhydro AS, explained in a press release. Schramm is working in conjunction with SINTEF to bring the concept to reality.
The proposal calls for turbines to be connected to large tanks at a depth of approximately 1,300 to 2,600 feet. When valves on the turbine are opened, water rushes in and turns the turbine. The mechanical energy creates electricity. When the water tanks are full, the turbines are run in reverse and function as a pump, sending the used water back up to the top, a method called pumped storage.
