and this is the hydro power station of xingo. it is a small one, much smaller than the paulo afonso station which is only a few hour up the sao francisco in bahia. i love big engineering, and power damns are about as large as they come. i am fascinated by the scale of the ingredients, the walls of cement, the static and profound lakes created upstream, the tension which permeates the air outside, the crackling of the powerlines and the danger signs everywhere speaking of voltage and electricity. and i absolutely love the elegant simplicity of the fundamental science that underlies the entire endeavor. yes, im a geek. but a romantic one :)
