This Hydro electricity units use flowing water to spin a turbine connected to a generator. In a falling water system, water is accumulated in reservoirs created by dams, then released through conduits to apply pressure against the turbine blades to drive the generator. In a run-of-the-river system, the force of the river current applies the pressure to the turbine blades to produce electricity. In 2000, hydroelectric generation had the fourth largest share 7 percent of electricity production at 273 billion kWh. -447 The geometric arrangement of the mirrors is interresting. It will raise alarm bells for environmentalists. Its probably safe to assume that natural formations do not occur in perfect eliptical bowls facing south very often. So, youre going to have to move a lot of earth to make one of these, and its going to be on the scale of a big strip mine or mountain-top removal process. You could minimize the evils and try to use mountaintop removal sites and other existing excavations, and convert them to this purpose after the mining is done, I would guess. Its still going to leave a got-awefull gaping hole in the ground covered in mirrors.
