Solar-Prism Technologies





The Solar-Prism is a highly efficient, economical and effective solar collection system. The Solar-Prism (SP) collects the longest solar-hours, as its base-angles correspond to the best solar-tilt-angle of the installation location. The SP provides up to 2.5X the surface area of a normal flat-panel footprint; on a farm-arrangement reflectivity between the SP units further increases the array's collection potential. The SP design is functional, environmentally sound, friendly to the local ambiance and is aesthetically pleasing. The SP technologies consists of the PortalGen Unit, Solar-Prism Concentrator Unit, Solar-Prism Brine Electrolyzer Unit, Solar-Prism Desalinator Unit and the Solar-Prism Hot Water Unit.


PortalGen Unit


PortalGen is a Solar-Prism based technology that can function as a stand-alone integrated photovoltaic and energy storage system, using multi-stage fly-wheels to produce a high capacity power source. This power source can be harnessed as an Uninterrupted Power Supply (UPS), for power transmission network stability, spinning reserve for frequency leveling, and as a feeder/supply for peak-load demand in high-load facilities (including as a back-up for remote power generation installations such as wave or wind generators, thereby increasing the generator's reliability, efficiency and availability). PortalGen is ideal as a Distributed Power System (DPS) installed on the roofs of major buildings, hospitals and schools. PortalGen has been fully granted patent protection in the United States of America [No. US008240231B2]; Click to view the US patent certificate. In Australia, the Patent number [PCTAU2006905282 and AUS2007302602] has been accepted, as published in the Official Journal of Patents on 2 February 2012.


The PortalGen unit is capable of being discharged for longer periods and re-generated within a short period, rendering it ideal for overcoming the inefficiencies on the network poles and wires, as well as generation capacity issues. Driven mechanically, yet automatically, with high reliability, PortalGen can technically address the instability of isolated network-systems effectively as never before by anyone.


The unit is also a best practice solution for electric trains, both long-distance and suburban, as it will reduce the power consumption by 50% through a hybrid-regenerative system and addressing the intermittent but very high-current load demands on starting. These applications are common issues in all heavy engineering and major processing plants globally. The net-outcomes of PortalGen addresses these issues by delivering energy efficiency, meaning better ecological sustainability, cheaper running costs, cheaper fares for all communities and real demonstrated savings.

Solar-Prism Concentrator Unit


The SP Concentrator (SPC) Unit stores solar heat-energy in exotic-mediums such as mercury, oils or brine (EM1). EM1 is then applied to a combined-cycle low temperature gas medium (EM2) such as silicon, ammonia and helium to propel a turbo-generator to generate clean energy.


The SPC Unit can be scaled-up from a Distributed Power System (DPS) to large-scale base-load continuous power generation.



Solar-Prism Brine Electrolyzer Unit


The SP-Brine Electrolyzer (SPE-Brine) Unit is an on-line brine electrolyzer to extract Hydrogen gas (H2) out of waste from desalination plants, in an environmentally friendly way.


The power for the overall process is supplied by the integrated solar photovoltaic system contained in the SPE-Brine Unit. H2 gas is fed into a Fuel Cell to generate electricity for the desalination plant as co-gen, or to be exported to grid as renewable energy.


Solar-Prism Desalinator Unit


The SP Desalinator (SPD) Unit is a compact, stand-alone, on-line system for a continuous desalination process producing potable water for drinking. It is an integrated unit consisting of solar, in-built water reticulation off seashores, river ways, canals or dams/reservoirs and storage reservoirs, through to storage and filtration.


The SPD unit can be scaled-up from home usage through to a Distributed Water System.


Solar-Prism Hot Water Unit


The SP Hot Water (SPHW) Unit is a compact, stand-alone photovoltaic system to supply enough power for existing hot water units on houses, major buildings, hospitals, schools, industrial complexes etc.


The SPHW Unit is installed on the existing roof of building structures or on the ground.
