Document Summary
It is possible to reverse pump hydroelectric resources to store electric power from fluctuating wind or solar resources like a giant battery. Read p 283 our choice. (listen to elon musk on tesla power wall and mass storage roll out for contrasting view. ) Common american farm windmills pump subsurface water into a reservoir tank for irrigation, livestock, firefighting and hydropower. Common water towers or hill top reservoirs store an elevated water volume about. Water pressure = rho (density) x g (gravity) x h (height of reservoir). Half a psi per foot of elevation is an easy rule of thumb. For very low pressures as produced by a fast moving stream, a shoot under water wheel is appropriate. Ilulissat area is the first in greenland: the paakitsup akuliarusersua basin is 45 km north of ilulissat, with about 325 sq. km of total area. Only 40 square kilometers of this basin are ice free and the remainder is beneath the inland ice.
