Fracking involves drilling a borehole before a high-pressure water mixture is directed at the rock to release the gas.
The device is a hinged flap connected to the sea-bed which uses wave power to deliver high-pressure water to an onshore turbine.
The underground storage areas are created by removing salt in the rock strata with equipment similar to high pressure water jets.
When water velocity is high, the pressure within the liquid drops to below the vapour pressure of water, allowing tiny air bubbles to expand.
Because it's so hard in water and to maintain voice features, one of the other aspects of this is that when you dive down the pressure increases, the water pressure increases and actually changes these air filled cavities and you have that influence voice characteristics quite a lot.
The population is growing rapidly, putting more pressure on water supply because demand is increasing but supply is not.
The prime minister, Yasuo Fukuda, will come under huge pressure to water down the ideas before he submits them to the Diet (parliament), as part of an economic plan, in June.
Due to the amount of water needed, residents have been left with reduced water pressure and, at times, no water.
High demand for water amid the heat wave and problems with soil shrinking as the ground warms has resulted in burst pipes and low water pressure in Oklahoma City, prompting officials to issue mandatory water-use restrictions for the first time in at least a decade, according to utilities department spokeswoman Debbie Ragan.
The company said some residents in and around Liverpool city could notice temporary low water pressure or a loss of supply as engineers re-route water supplies to all customers.
In Houston last summer, there were 700 water main breaks every day due to aging pipes and pressure from increased water use and dry soil.
The salt of the seawater draws the fresh water across the membrane, leading to a build-up of pressure which forces water through the turbine, generating electricity.
When the high water pressure is released after the fracturing of the shale, some 10 percent to 30 percent of the water comes back to the surface.
Weep hole: hole through a solid revetment, bulkhead or seawall for relieving water pressure.
More ingenious still, the capsule itself has been designed to regulate the pressure pushing the water.
"The electronic instruments are not built to withstand water pressure at 3, 500 metres, " Mr Faure said.
It uses intense water pressure to shape a car's steel body panels on half a stamping die.
Basically, the Fed did not maintain adequate water pressure in our economic plumbing while investors were busy constructing bigger pipes.

When pressure forces the water up other, nearby wells, it is hot enough to run a turbine and produce electricity.
Water pressure keeps the device open, and steel rollers help it to bounce over tricky rocks and avoid getting snagged.
The acrylic plate to protect the LCD from water pressure and shocks is 1.5 times thicker than conventional point-and-shoot cameras.

The air is then pumped out and water pressure pushes the pile into the ooze, as shown in the second diagram.
Mike McKimm said the polystyrene cups were slowly crushed by the massive water pressure as the craft descended towards the sea bed.

Fracking uses high-pressure mixtures of water, sand or gravel and chemicals to crack rock formations and release oil and natural gas deep underground.
As water is flowing, the throttle is manipulated to control the water pressure being supplied to the discharges, this in turn affects the flow rate.
I'll list just a few: rear cleanse, front cleanse, soft rear cleanse, oscillating cleanse, water pressure control, nozzle position adjustment, "SoftClose" seat and air purifier.
However, after the 1996 capital gains tax cut got our economic pipe fitters working overtime, the Fed stood idly by while the our monetary water pressure fell.

The tribe has money for more housing, but can't build because the water pressure is too low and its treatment systems too outdated to handle increased demand.
There were also discussions around innovation that would be more relevant to utility markets such as smart metering, leak detection, pressure regulation, water quality monitoring and more.

Hydroforming uses water pressure (up to 15, 000 pounds per square inch) to force the flat steel against a one-sided tool, achieving the same result for half the cost.
