Even though this system does not generate new energy (there actually is a reduction in energy due to losses involved in pump and turbine operation as well as in the electric motor and generator), pumped hydro-storage often becomes economical when compared with the cost of constructing additional turbines for peak power demands.
Mr Cameron said he had also ordered new high-volume pumps from the "national reserve" to be sent to the area "to increase the volume of the pumping operation as soon as there's capacity in the rivers to support that".
It was important that Harvey saw the heart as a pump, but he saw it as an organic pump, rather than as a mechanical pump.

"The general theory is that there are faults in the region of the hydraulic fracturing operation, and as you pump large amounts of fluid underground, the presence of fluid could increase the chances of slippage on a fault," Gu explained.

MOGA model applied in Wadi El-Farigh, Egypt, to develop the maximum pumping rate and minimum operation cost as well as to predict the future changes in both pumping rate and pumping operation cost.
If that is accomplished, BP will pump higher volumes of mud, and possibly cement, into the well, in an operation known as a static kill or bullheading.
