摘要:

This paper presents results of a preliminary design/economic study of a first-generation Point Focusing Distributed Receiver (PFDR) solar-thermal electric system optimized for application to industrial and small community power plants at power levels up to 10 MWe. Power conversion is provided by small Stirling cycle engines mounted at the focus of paraboloidal solar concentrators. The output of multiple power modules (concentrator, receiver, engine, and electric generator) is collected by means of a conventional electrical system and interfaced with a utility grid. Based on the United Stirling (Sweden) P-75 engine, a 1 MWesystem employing mass-produced components (100 000 modules/year) could produce electricity at costs competitive with those projected for electricity generated by more conventional means, eg with fossil fuels.

摘要:

This paper investigates the relative effectiveness of passive-type solar-assisted space heating systems at various latitudes within the British Isles. A comparison is made of the useful solar gain of the same system linked to the same house at four different locations.

摘要:

A group of promising phase change heat-storage materials was selected through study of the literature, laboratory tests of freeze—melt behaviour and determination of thermophysical properties. Means were developed of encapsulating these materials in metal or plastic containers. Four of these phase-change materials, suitably encapsulated, were tested in a sub-kale thermal storage unit of about 20MJ capacity, using air as the heat-transfer fluid. In most cases, measured thermal-storage capacity exceeded 90% of the theoretical value. After considering a number of heating and cooling schemes employing phase-change heat storage, we selected a forced hot air, central storage design, using CaCl2.6H2O encapsulated in plastic pipes. A home was designed, using a two-storey conservatory for solar collection with vertical glazing and movable insulation.

摘要:

The application of increased energy conservation standards and of solar energy to an educational project—as opposed to the more frequent domestic application—is the subject of this paper, which describes how these measures were applied to a new village school in Cornwall.

摘要:

Ocean Thermal Energy Conversion (OTEC) can provide energy to all countries. It can deliver the energy (i) to regions bordered by warm ocean waters via direct electric-power transmission or (ii) to other areas not bordered by warm ocean waters, via an energy-intensive material produced on OTEC plant-ships cruising on the high seas in the tropics. Ammonia is an outstanding choice for an energy-intensive material because it can (a) replace ammonia now made from natural gas to conserve fuel, (b) serve as a synthetic fuel, or (c) provide an easily transported, storable source of hydrogen for fuel cells to generate electric power where needed anywhere in the world. Costs of OTEC ammonia and of electricity delivered directly or via fuel cells are projected to be competitive with costs of electricity from coal or nuclear plants by 1990, if rapid OTEC development is pursued.
