In the case of BrightSource’s concentrated solar power site near Ivanpah in the Mojave Desert, there are some 350,000 mirrors that focus light on three boiling towers (each about 40 stories high). The plant cost $2.2 billion to build, with most of the money coming from a US Department of Energy loan, and sizable investments from NRG Energy and Google. The three plants have a total capacity of 392 megawatts and an annual production of around 1,000 gigawatt-hours of reasonably priced electricity.
How much does your average Hydro-electric system cost to build these days that will produce 88mw
So they just devote 50 mW to pumping the water back up into Kareeya power station during the day.
Awake yet.
Perhaps it is you that cannot comprehend scale.
