The division of energy among the various competing processes is discussed in the sequence from the collection of the solar flux, to the production of electrical power at a busbar output'' for the Shallow Solar Pond scheme. The solar collector utilizes shallow flowing water to transfer thermal energy to a hot water reservoir (at approximates 95 deg C). Several layers of plastic sheet cover the collection area to suppress heat losses. A Rankine Cycle thermodynamic system converts part of the heat energy to shaft work and thence to electricity. It would utilize a Freon gas turbine, along with evaporator, condenser and pressurizing pump; the rejected heat would be removed by an evaporation pond (at approximates 25 deg C). The fiducial system used for this analysis is assumed to have an area of 1 km/sup 2/. It would figuratively deliver an output of 81/2 MW; its mean efficiency for the reference input is 2.8%. The reference operating point corresponds to equinoctial noon, 33 deg N lat. (No attempt was made to include a summer- winter optimization). The various losses and power expenses are summarized, (MCW)
