Malaya Valley Geothermal Power Plant

Located near Petropavlovsk-Kamchatsky in Russia, this plant pumps water deep underground through specially drilled-in holes. The water then reaches naturally heated layers of the Earth crust and as it percolates through hot granite, continues to increase in temperature until it evaporates, producing steam that rises up the ground in geysers. The hot water returns to the power plant heat exchanger, where its energy is translated into power. The process turned this reservoir into turquoise-tinged acid. So as pretty as it may be, dont go swimming it unless you dont miss having skin.
