Abstract: A system [500] for producing solar energy at a desired temperature and pressure range includes a primary energy source [501] that is used in a Clausius Rankine cycle, with the primary energy source connected to and proximate to a plurality of solar collectors [520]. More particularly, at least one steam storage tank [501] feeds the expansion step of the Clausius Rankine cycle. This enables the system [500] to reliably supply energy during times when the solar collectors receive little or no radiation. According to one aspect of the invention, the solar collectors [520] reside on an artificial island [510a, 510b, 510c], preferably sea-based, or offshore, so that the steam storage tank [501a, 501b, 501c] can be located well below sea level. This enables the use of compressive forces from the sea water to counteract the outwardly directed pressure caused by the steam contained in the steam storage tank [501a, 501b, 501c].
Abstract: A man-made island adaptable for land-based operation holds solar energy collection facilities and is rotatable to optimize the angular orientation thereof relative to the position of the sun. A platform includes a large outer ring that floats on a fluid and a flexible cover is attached to the ring to define an airtight volume below the cover. A plurality of rows of solar radiation collector modules are located above the cover and carry steam generating heat pipes. The rows of modules are supported laterally above the cover by an upper support structure, either a space frame, a plurality of cables, or a honeycomb. A compressor creates an over-pressure within the enclosed volume to vertically support the cover and the other components mounted thereabove.
Abstract: A man-made island [10], adaptable for land-based or sea-based operation holds solar energy collection facilities and is rotatable to optimize the angular orientation thereof relative to the position of the sun. More particularly, the man-made island [10] uses a platform [12] that includes a large outer ring [14] that floats on a fluid, and a flexible cover [16] attached to the ring [14] to define an airtight volume [30] below the cover [16]. A plurality of rows [19] of solar radiation collector modules are located above the cover [16], and carry steam generating heat pipes [21]. The rows [19] of modules are supported above the cover [16] by an upper support structure, either a space frame [27], a plurality of cables [46] or a honeycomb [75]. A compressor [32] creates an over-pressure within the enclosed volume [30] to assist in supporting the cover [16] and the other components mounted thereabove.
