SolarReserve has finished construction on a massive solar tower for its 110 megawatt plant (the largest of its kind) in Nevada. Get an up close view of the project via photos and a time lapse video.
SolarReserve has completed a 540-foot solar power tower, the centerpiece of its 110-megawatt Crescent Dunes solar thermal power plant that will use molten salt storage to help it supply power day -- and night.
SolarReserve still has to install the 10,000 billboard-sized sun-tracking mirrors or heliostats necessary to concentrate sunlight onto the massive tower at the site of the solar plant in Tonopah, Nevada. The power plant, which is expected to come online by December 2013, will be the largest of its kind in the world, according to the company. Crescent Dunes has secured a 25-year power purchase agreement with NV Energy and will provide electricity for 75,000 homes. Check out the time lapse video provided by SolarReserve below.
The critical component of the Crescent Dunes project is its molten salt storage. The reflected sunlight is directed onto a large heat exchanger called a receiver, which is located on the tower. Molten salt -- not oil like other concentrated solar power plants -- is within the receiver and absorbs heat from concentrated sunlight, reaching up to 1,000 degrees Fahrenheit. The molten salt flows down the piping inside the tower and into a thermal storage tank, where the energy is stored until electricity is needed.
When the utility needs power -- again, at day or night -- the high-temp molten salt flows into a steam generator, which drives a turbine to produce electricity. The cooled molten salt is then piped back into a cold salt storage tank and eventually back up to the receiver to start the whole process over again. According to the company, its technology has the ability to store energy for 10 to 15 hours. In other words, the solar power plant will be able to provide a continuous supply of power.
Variability is among the biggest problems with solar-generated power, which the SolarReserve project and others like the Gemasolar plant in Spain are designed to solve. When the sun sets, the renewable power source drops off and that can create problems for grid operators trying to maintain a steady electricity supply. Without access to solar power, the utility will switch over to natural gas- or coal-fired power plants.

A power generation turbine exhausts into, and usually sits right on top of, a condencer under a very high vacuum. The steam is cooled and changed to water in the condenser and the water is reused in the cycle. This steam cycle, called the Rankine cycle, has been used for more than a century. Some water will have to be supplemented as "make up" because there will be small losses during the operation.
I hope they recapture the steam used to power the turbines...the waste of water if it didn't would be ridiculous and would defeat the purpose of this being "green" in the first place.
Renewable Energy Solar, Wind, Hydro, Geothermal and others should be on the front cover of every Science Book kindergarten through high school. Leaders and Schools in all Nations need to Teach more on Solar Energy. When this Old World starts getting you down. From Pollution the cost of OIL, Heating Fuel,The Fuel you put in your Vehicles, You Electric Bills from cooling air conditioners and lights not to speak of the Evil. The TAX that all Governments Federal, State, County and City put on everything they can thing of. They are supposed to serve us. Not put a burden on its people. That they are elected to serve all the people you, not their own Pocket Books. The Wicked keep putting higher taxes on everything. Making it a Heavy Burden on many that are already struggling just to put food on the table. Too many Americans and People of all Nations have lost their home to the tax collector or to foreclosures from the unjust bankers greed and their Government leaders. More are out of work and lost their homes then in the GREAT DEPRESSION, in the last ten years. All Americans and many Nations need good jobs and more of them. Not more TAXES and Wars. There is a Industry that will employ workers and is growing by more then 50% every year. There is a clear way for all up on the roof the Sun Light is free fuel from GOD. Some wicked in Government have been backing Coal, Oil, Gas and the Nuclear industries for too many years. These kickbacks to them were called Subsidizing Industry Technology and high paid scientist. Most all Wise Men and smart Economist, Environmentalists and good at heart Scientist call this padding their pockets and subsidizing back to the Stone Age. This might even been funny in the 1960???s. If it were a Fred Flintstones and Barny Rubble Movie. About How to aggressively systematically work with the rich to Pollute Ground Water quality to the point it is unsafe to drink or use. So to they make a law you can only buy water from their pipe line. And to make the air we breath full of Toxic Gases, Sulfur Dioxide and more Radioactive and Acid Rain. Injuring all living things on Earth. With Fred Flintstones to the Rescue. To help create a Healthier Environment. For all Future Generations. By spotlighting Renewable Energy and Free Energy like Wind and Solar. On his and his neighbor Barny Rubble???s roof. Even though the greedy wicked would do everything to stop or slow them down. Just imagine a dream that a 100 years ago one of the smartest man to ever live had. A dream after working with Sun Light. That all on Earth would use Free Energy Solar Energy. That Dream also shared by a man that dreamed this over 2,250 years ago. Both These men showed the world in their days. That this dream of Free Energy Solar Energy World wide was very possible. Both of these two wise men had first hand worked and researched their experiments for not just days, weeks put for many years. One of these men used chalk on Black Board the others board was a black stone table or floor covered with white sand and used a stick. One of these two Brilliant men had Kings from all most every Kingdom on Earth come to him for advice. The other went to almost every nation on Earth. Freely on his own dime Teaching All that had ears to hear. He would win the Nobel Prize for doing so. For his work on Solar Energy. Only after years of doing research and when most Scientist on Earth would not take the nomination for the Nobel Prize in 1921 and knew it clearly belonged to this Brilliant Scientist, this Brilliant scientist was then awarded it in 1922 for the 1921 year. Now if this was just a Pretend TV Show or a Movie from a dream. This would be a great Sci Fi Story Line. In the 1960???s or even better to day. Sci Fi story Movie or dream No. All that i Have told you did actually really happen. Albert Einstein won the Nobel Prize for what? When Government leaders asked him to go on stage. To address the Scientific Community and the World. About what he was given the Nobel Prize for. When Albert Einstein Had done so. He addressed them with his other accomplishments. For years most Governments did not have a ear for Einstein???s Dream. Archimedes around 250 B.C. was know most of the World over as a great Mathematician. One of the first Scientist and Inventor of many things. Even the first Laser Ray from the Sun???s Energy. Science Fiction is what you would have though you were seeing if you could go back in time, it was real.To day we call it The LASER, Light Amplification by Stimulated Emission. Back then it was just called Amplification of the SUN, Archimedes Death Ray. Thousand of years later it would be a Laser. That Albert Einstein help make possible. That would unlock one of the first books on Earth. The METHOD written by Archimedes. Then over more then 250 years later. When well Faded was cut from a scroll and put into a book form, to be easier to hide from the Romans by St. Paul. This book sold for over 2 million dollars. In New york at Christie???s Auction House. These two are at the top of the list of the World???s Greatest Scientists, Viewed by Scientist around the World. Sad that for the last 25 years or so of every teacher asked no matter what Grade k through 16. At least 80% of them did not know Archimedes. Even sadder 90% of them could not tell you what one of the most Brilliant Scientist to ever live on Earth. Won the Nobel Prize for. It was for the work Albert Einstein did to show the World it could get Free Energy, Electric from the SUN. (THE PHOTOVOLTAIC EFFECT). You ask this question to any Military general 95% of them will get it right. Even more surprising 99% of them will know more about Archimedes then most Teachers on Earth. Generals know Energy is the key to Winning. At almost one thousand to one Archimedes always won against what all knew was impossible odds. Archimedes home town city of Syracuse was victorious against the greatest Kingdoms Armies on earth many times. Syracuse once was one of the most powerful cities in the World. I can only ask you to please look into Solar Energy, Solar Power, Solar Panels and Solar array on the internet under Images. To see and explore for your self then you be the JURY. More then 10 years ago the Internet became most of the World???s Universities Learning Platform. A Modern Day Archimedes Resource Center. The Solar Energy Industry in the year 2010 and 2011 has leaped ahead farther and faster then any other industry on Earth. The Solar Industry in the United States of America alone, has grown by more then 50% in 2010 and that number has gone up even higher for the 2011 year. The strong benefits of Solar Energy is Clear Clean Air viewed in major cities as improving air quality. Clean Cities. By all that use there brain for good . View it as protecting the environment and Freedom from OIL , Coal and other Dirty Energy. While many Governments has eased the Taxes on Renewable Energy . Some cities in the states that these Legislators come from have worked against these tax credits. By doing so they are showing their true objectives. That they have stock in some power plants and do not want to lose all that Money they have been taking out of your pocket books for too many years. By taxing you on your Energy Bills. They want to Control Power and Tax Everything they can. Not let People be free to get their own power from the top of their own roofs. By adding their own taxes to them. These wicked leaders think that this will take away the incentives to harvest the Free Energy from the Sun. The Public ability and awareness for all on Earth to use the Natural Solar Energy, is Contributing to Production of Solar Energy Products. Making the Solar Energy Industry the fastest growing on Earth. A Wealth of Free Energy From The SUN. The more the wicked try to slow the Solar Energy Industry down, it only Enhances involvement and the efforts of the Good at Heart. through out History Many have tried to wipe the good from our history books. Read the Bible Jesus will Bless you more then i can. SolarWorld has been presenting a Einstein Award to personalities who have advanced the use of solar energy ??? and helped our Planet Earth. We all need to tell all our Teachers and Leaders to use our Nation???s Energy more wisely and efficient. Start to Teach all our Young about Renewable Energy Solar, Wind, and so on. Not to for get Flintstones, Fred well there are many the one that is in front of all others Started back in the 1970???s and started a small catalog that has turned into a Wealth of knowledge into Renewable Energy a book called REAL GOODS Solar Living Source Book. By Mr. John Schaeffer. The world is going more with SOLAR, Wind and Geothermal Powered Energy. Speaking of Geothermal Curt Lubben is just one of many sales representatives that has sold over a million dollars of Renewable Energy in less then 365 days in the year 2011. The day of the need for Dirty Oil, Coal and Dangerous Nuclear Power are coming to a end fast. The Freedom Element Living with Hydrogen That Dr. Addison Bain has showed the world will free most all of the need for the Power Grid and Oil CEO's. Very soon most of the world will not need Oil. Renewable Energy like Solar, Wind, Hydro and Geothermal are now replacing dirty Energy like Oil. Solar Energy is growing World Wide at a record pace. Hybrid Cars are being sold all over the Earth. Soon Hybrid Vehicles that run on Electric / Hydrogen, The Freedom Element. Will free the world from Oil. Thanks to a Great Scientist Dr. Addison Bain???s Years of work for our Nation and with the Space Program on Hydrogen. The day will come when many will see Solar Panels on most everything. What Free Electric the sun makes will be used to split water into Hydrogen. The Hydrogen will be used to heat our homes and to cook on and put into are Hybrid Vehicles that will run on (The Freedom Element). Very soon most all will be filling up their Vehicles at Home. Free from the Sun???s Solar Energy. Just as Dr.Addison Bain has done for years The Fist Hydrogen Home Refueling Station in the World. That Dr. Addison Bain built by his self. GOD Bless you for reading this. May our Lord and Savior Jesus Christ guide your Heart. The Lord???s little Helper Paul Felix Schott
Similar, but smaller, systems already have water usage up to a million gallons a year. This is a common design flaw in CSP systems. Based on the history of the industry I would not bank on it.
The implementation of the "solar power tower" in a desert with no supply of water would logically result in a closed loop system. It is logistically improbable to transport the water continuously to that site every day to be evaporated into the atmosphere.
I have not seen the design specs for this particular system, but read up on all the CSP systems being built in the desert southwest of the US and the designed annual water usage exceeds a millions gallons. That does not sound closed loop to me. I have no clue how they intend to get the water beyond draining already over extended underground wells and dammed rivers. How they get approval for such projects in states going through droughts is another mystery.
