Ivanpah Solar Electric Generating System and the Pyramids of Giza

We found that there is a great similarity in these two images from Space. The one photo has the well known Pyramids of Giza, in Egypt and the other the Ivanpah Solar Electric Generating System in Ivanpah Dry Lake, California.    Concept by wordlessTech

On December 25, 2013, the Operational Land Imager (OLI) on the Landsat 8 satellite acquired this natural-color image of Ivanpah Solar Electric Generating System. The three towers and surrounding arrays of mirrors stand just a few kilometers from the California–Nevada border, just outside Mojave National Preserve, and 65 kilometers (40 miles) from Las Vegas.

The new solar power plant sits within Ivanpah Dry Lake on 3,500 acres of public land that sees 330 to 350 sunny days per year. Operators say they will be able to generate 377 megawatts (MW) of electricity, enough to power more than 140,000 homes. After four years of construction, the power station officially opened in February 2014. It has been called the largest solar thermal power tower system in the world.

At Ivanpah, more than 170,000 mirrors are spread out over 13 square kilometers (5 square miles). The mirrors—called heliostats—rotate and change angles to focus sunlight on the central towers, which stand 140 meters (460 feet) tall. The focused sunlight heats water to drive steam turbines and generate electricity. Smaller versions of such solar power tower systems have previously been constructed in Spain and Germany.

Proponents of this new solar energy harvest assert that the complex will reduce carbon dioxide emissions by 400,000 tons per year. Some conservation groups have expressed concerns about lost habit for species such as the desert tortoise and about threats to birds, which can be harmed or killed by the intense heat above the mirror arrays.
