<br />< , <br /> <br />w <br />c.n <br />...., <br />~ <br /> <br />, <br /> <br />Agriculture <br /> <br />Low temperature solar ponds (50-S00C) can provide a variety of thermal <br /> <br /> <br />requirements for facility heating, crop drying, and farm product <br /> <br /> <br />processing_ <br /> <br />Solar pond temperatures can be matched to the mash cooking step of <br /> <br /> <br />producing ethanol and~ at SooC, can be used for vacuum distillation. In <br /> <br /> <br />developing solar pond applications to ethanol production by distillation, <br /> <br /> <br />emphasis would be placed on low-temperature distillation techniques. These <br /> <br /> <br />ponds could serve as energy complexes for multi-farm ethanol production <br /> <br /> <br />facilities. <br /> <br />Electric Generation <br /> <br />The solar pond electric generation facilities will probably use organic <br /> <br /> <br />Rankine-cycle systems designed to operate at relatively low temperatures <br /> <br /> <br />(SOOC and up). Advanced subsystems, are in the process of being arranged <br /> <br /> <br />through an interagency agreement between the U.S. Water and Power Resources <br /> <br />Service and the Solar Energy Research Institute, This agreement includes <br /> <br /> <br />the following tasks: <br /> <br /> <br />(a) Development of thermoelectric power cycle coupled to solar ponds. <br /> <br />(b) Conceptual design of a solar pond power cycle using an organic <br /> <br />working fluid Rankine-cycle with a direct contact evaporator and <br /> <br /> <br />condenser. <br /> <br />Grid-connected electric designs will be constructed in modules of 20-50 MW <br /> <br /> <br />each, (a size recommended by Jet propulsion Laboratory for the Salton Sea <br /> <br /> <br />Project). These modules can be aggregated into complexes approaching 600 <br /> <br /> <br />megawatts. <br /> <br />-6- <br /> <br />___n i. _^ :c <br />
