Energy 101: Concentrating Solar Power

From towers to dishes to linear mirrors to troughs, concentrating solar power (CSP) technologies reflect and collect solar heat to generate electricity. A single CSP plant can generate enough power for about 90000 homes. This video explains what CSP is, how it works, and how systems like parabolic troughs produce renewable power. For more information on the Office of Energy Efficiency and Renewable Energy’s CSP research, see the Solar Energy Technology Program’s Concentrating Solar Power Web page at www1.eere.energy.gov

    Its still surprise me, just how lots of people do not know about Xobotano Home Energy (do a search on google), although lots of people save huge amounts of money with this alternative energy. Thanks to my work buddy who told me about Xobotano Home Energy, I’ve cut my electric bill by 75% in under 1 month

  3. no idea, if i lived in a country where it was practical to produce energy this way, i’d be unequivocally for it. write your congressman or senator or whoever

    I wonder if you could do a hybrid concentrated solar/geothermal power plant with both a high temp steam power turbine and a lower temp power system (refrigerator compressor running backwards, temperature differences making electricity instead of electricity making temperature differences) basically you uses solar in the day and the geothermal resource at night, throwing any excess solar generated heat underground.

  5. CSP is an attempt to squeeze solar into the old energy central station model. These systems are highly inefficient, expensive and are rapidly being out-competed by distributed solar PV. Point of use solar in the VAST built environment is cheaper, faster and generates more local economic benefits while protecting our intact desert ecosystems and nation’s cultural legacy.

  6. Everybody should be responsible for their own power and each house be powered with solar energy.

    research the venus project. we can power our earth with this and other clean technology. but only by removing money from society. as long as we live with money we will not live with this technology fully.

  8. Haha, I was thinking about storaging heat. There is still something missing in this idea, you can use it for desaltination of sea water and use that water to provide energy trough a water power central.

    Do solar flares and sunspots have any adverse effect on solar energy systems?

    about 5 km² for a small coal plant, which is not much considering just the Mojave desert is 65 000 km²

    Stop mixing up the numbers here!

    250MW peak times 8760hours a year equals = 2,19TWh. (250 * 10^6 J / s * 8760h/year).

    Of course its not peak all the time (because of night and shade and sun – angles) . Say its peak sunny about 2500 hours/year. Then the produced amount would be: 250MW * 2500h/year = 0.625TWh or 625GWh. Still a handsome amount of power from a desert that can’t produce anything else of value.

    Free Energy is real and it’s here but the coverup is strong, if u r interested in a REAL free energy magnet motor then

    just go to LT-MAGNET-MOTORdotCOM and download the blueprints ,it’s probably the ONLY working magnet

    motor out there. Join the free energy revolution!!

    Free Energy is real and it’s here! The Oil companies r doing everything they can to stop this

    information. If you want a Free energy magnet motor , get the blueprints at LT-MAGNET-MOTORdotCOM , Join the

    revolution!
