A group of artists , scientists and engineer have declare oneself a refreshing resolution to avail Copenhagen ’s accomplish its destination of becoming a C - electroneutral metropolis : a 12 - account - mellow solar energy farm in the shape of a duck’s egg .

Energy Duck is the brainchild ( brainduckling ? ) of theLand Art Generator Initiative(LAGI ) , which designs public art installations that also function as utility - scale unclouded vigor generators .
So , why a duck?According to LAGI :
The common eider duck’s egg resides in great Book of Numbers in Copenhagen ; however , its breeding habitat is at hazard from the effects of climate change . Energy Duck takes the form of the eider duck to act both as a solar collector and a buoyant Department of Energy storage equipment .
Solar radiotherapy is converted to electricity using low cost , off - the - shelf PV panels . Some of the solar electrical energy is stored by chastity of the difference in water levels inside and outside the duck .
When stored vitality postulate to be delivered , the duck is flooded through one or more hydro turbines to give electricity , which is transmitted to the national gridiron by the same road as the PV venire - bring forth electricity . Solar vigor is later used to pump the water supply back out of the duck , and buoyancy bring it to the surface . The float acme of the duck indicates the proportional toll of electricity as a affair of citywide use : as need peak the duck sinkhole .
