  7. Problems with Trough Concentrators STANWELL POWER STATION PROJECT Graham L. Morrison1, David R. Mills2 and Stanwell Corporation “The tendency has been to produce larger and larger scale systems to produce economies of scale and lower installation cost, but with contiguous reflectors there are limits on manageable size. Scaling up of parabolic trough or dish collectors for large solar thermal power systems is limited by wind loading problems and shading between adjacent concentrators. The aperture width of the LUZ parabolic trough collectors is 5 m and the adjacent rows were spaced by approximately 10 m. Larger units become progressively more difficult to install and clean.” http://solar1.mech.unsw.edu.au/glm/papers/CLFR-Geelong99V6.PDF _____________________________________________________________________________________________ The information here is the proprietary and trade secret information of MeV Technology, Inc.

  8. Problems with Dish Concentrators Parabolic dish concentrators are similar to trough concentrators, but focus the sunlight on a single point. Dishes can produce much higher temperatures, and so can produce electricity more efficiently. But because they are more complicated, they have not succeeded outside of demonstration projects. http://www.ucsusa.org/clean_energy/renewable_energy_basics/how-solar-energy-works.html _____________________________________________________________________________________________ The information here is the proprietary and trade secret information of MeV Technology, Inc.

  20. Saturated Vapor Pressure The process of evaporation in a closed container will proceed until there are as many molecules returning to the liquid as there are escaping. At this point the vapor is said to be saturated, and the pressure of that vapor (usually expressed in mmHg) is called the saturated vapor pressure. Since the molecular kinetic energy is greater at higher temperature, more molecules can escape the surface and the saturated vapor pressure is correspondingly higher. If the liquid is open to the air, then the vapor pressure is seen as a partial pressure along with the other constituents of the air. The temperature at which the vapor pressure is equal to the atmospheric pressure is called the boiling point. http://hyperphysics.phy-astr.gsu.edu/hbase/kinetic/vappre.html _____________________________________________________________________________________________ The information here is the proprietary and trade secret information of MeV Technology, Inc.

  42. Low Temperature Collection Systems Low-temperature systems (unglazed)operate at up to 18 F° (10 C°) above ambient temperature, and are most often used for heating swimming pools. Often, the pool water is colder than the air, and insulating the collector would be counter-productive. Low-temperature collectors are extruded from polypropylene or other polymers with UV stabilizers. Flow passages for the pool water are molded directly into the absorber plate, and pool water is circulated through the collectors with the pool filter circulation pump. Swimming pool heaters cost from $10 to $40/ft² [2004]. _____________________________________________________________________________________________ The information here is the proprietary and trade secret information of MeV Technology, Inc. San Jose, CA 95135 408-238-6351 www.MeVTechnology.com http://www.wbdg.org/design/swheating.php

  43. Mid Temperature “Flat Plate Collectors” Mid-temperature collectors are usually flat plates insulated by a low-iron cover glass and fiberglass or polyisocyanurate insulation. Reflection and absorbtion of sunlight in the cover glass reduces the efficiency at low temperature differences, but the glass is required to retain heat at higher temperatures. A copper absorber plate with copper tubes welded to the fins is used. In order to reduce radiant losses from the collector, the absorber plate is often treated with a black nickel selective surface, which has a high absorptivity in the short-wave solar spectrum, but a low-emissivity in the long-wave thermal spectrum. Mid-temperature systems range in cost from $90 to $120/ft² [2004] of collector area. _____________________________________________________________________________________________ The information here is the proprietary and trade secret information of MeV Technology, Inc. San Jose, CA 95135 408-238-6351 www.MeVTechnology.com

  44. High Temperature Evacuated Tube High-temperature systems utilize evacuated tubes around the receiver tube to provide high levels of insulation and often use focusing curved mirrors to concentrate sunlight. High temperature systems are required for absorption cooling or electricity generation, but are used for mid-temperature applications such as commercial or institutional water heating as well. Due to the tracking mechanism required to keep the focusing mirrors facing the sun, high-temperature systems are usually very large and mounted on the ground adjacent to a facility. Evacuated tube collectors themselves cost about $75/ft², but use of curved mirrors and economies of scale get this cost down for large system sizes to a relatively low cost of $40-70/ft² [2004]. _____________________________________________________________________________________________ The information here is the proprietary and trade secret information of MeV Technology, Inc.

  45. Solar Collector Efficiencies Solar Collectors—Solar collector efficiency is plotted as a straight line against the parameter (Tc-Ta)/I, where Tc is the collector inlet temperature (C ), Ta is the ambient air temperature (C ), and I is the intensity of the solar radiation (W/m²). Notice that inexpensive, unglazed collectors are very efficient at low ambient temperatures, but efficiency drops off very quickly as temperature increases. They offer the best performance for low temperature applications, but glazed collectors are required to efficiently achieve higher temperatures. http://www.wbdg.org/design/swheating.php _____________________________________________________________________________________________ The information here is the proprietary and trade secret information of MeV Technology, Inc.

  47. Existing Technology Pumped Storage Raccoon Mountain Pumped Storage Plant is located in southeast Tennessee on a site that overlooks the Tennessee River near Chattanooga. The plant works like a large storage battery. During periods of low demand, water is pumped from Nickajack Reservoir at the base of the mountain to the reservoir built at the top. It takes 28 hours to fill the upper reservoir. When demand is high, water is released via a tunnel drilled through the center of the mountain to drive generators in the mountain’s underground power plant. _____________________________________________________________________________________________ The information here is the proprietary and trade secret information of MeV Technology, Inc. San Jose, CA 95135 408-238-6351 www.MeVTechnology.com

  48. Why have pumped storage? Electrical energy cannot be stored. Therefore the energy taken from an electrical power supply grid must always be equal to the energy being delivered by the electrical power plants. If this were not the case, the frequency and voltage of the supply grid would deviate from standard values. Following severe disturbances of the supply/load balance, the supply system could collapse. Pumped storage plants solve this problem by storing electrical energy as potential energy: They pump water to an upper reservoir at times of surplus energy on an electrical supply grid-typically, at night. This potential energy is then released through a hydro-electrical generator at times of high demand. Figures 1a and 1b show a typical pumped-storage scheme configuration. http://www.hydropower.org/PSD/Articles/Benefits1.htm _____________________________________________________________________________________________ The information here is the proprietary and trade secret information of MeV Technology, Inc.
