“…The CPC technology developed over time since the 1960s and there is a wealth of information available on its performance and diverse range of applications (Winston, 1974;Baranov, 1965;Baranov and Melnikov, 1966;Baranov, 1967;Ploke, 1967;Hinterberger and Winston, 1966a;1966a;Winston, 1970). Modifications have been made for second stage enhancement of solar concentration typically applied for complete degradation of wastes (Sanchez et al, 2014). The CPC has the advantage of concentrating all the rays that fall on it without the need to make adjustment to track the sun.…”

Nutrients derived from urine such as nitrogen, phosphorous and potassium constitute valuable sources of fertilizers needed for growing plants and as alternatives to commercial fertilizers. Concentration of nutrients available from urine provides advantages of reducing the volume of transportation, the health risk and making nutrient application to soil stable and suitable. An exploratory review of a possible technology for concentration of nutrients from urine using solar power assisted evaporation and carbon dioxide trapping of evaporated ammonia is discussed in this paper as a potentially viable technology for concentrating nutrients from urine as well as another sequestration option to reduce carbon foot print in the environment.

“…Although the sun ray falling on the absorber is not focused, there is considerable concentration of sun ray concentration that can be attained with a CPC design. Specialized designs for ultra-concentration of sun rays involving second stage concentration have been developed for applications such as complete degradation of wastes [2].…”

Harnessing the freely available source of energy from the sun offers a number of additional benefits. Not least of these benefits is the fact that solar energy is an environmentally sustainable alternative. A four-wing compound parabolic concentrator (CPC) was designed as a modification of the regular non-imaging CPC concentrator that has a widespread use as solar collector. The design is intended to increase the angle of acceptance as well as concentration of energy from the sun. The conceptual design, mathematical formulation as well as construction and initial trial results have been presented in this paper. Pilot trials of the four-wing concentrator used for sanitizing both liquid and waste products produced satisfactory results. Improvements in terms of design as well as material used for construction and better preservation of heat can be considered further in the future research.

“…Under the best angle, the deep one can approach 46% thermal efficiency, 40% higher than the shallow one. Miriam Sánchez et al [6]design an ultrahigh solar concentrator and carry out optical analysis to it. Meanwhile, technical feasibility of using solar energy is validated, especially high temperatures with relatively simple devices.…”

Abstract-This paper explored the thermal performance of evacuated tube solar collector with/without a semicircular compound parabolic concentrator (CPC). The configurations of tested systems were: (1) the system without CPC, (2) the system with Model A CPC (3) the system with Model B CPC. This work investigated and compared the thermal efficiency of the evacuated tube solar collector with the CPC by the surface temperature measurements of the evacuated tube solar collector and temperature difference comparison in water tank. Under the following experimental conditions, experimental data indicated that thermal performance of back surface for evacuated tube solar collector can be improved by CPC assuredly. Furthermore, we discovered that two systems with Model A CPC and Model B CPC can improve the efficiency of water temperature in water tank than the system without CPC. The test results showed that CPC can improve thermal efficiency of evacuated tube solar collector effectively while thermal performance was effected by radial size of CPC. To some extent, the bigger the radial size of the CPC, the higher the thermal efficiency. These experimental results provided basis and reference for practical application of Solar Water Heater (SWH).
