  • Exergy of solar radiation

    Solar radiation reaching the ground is accompanied with radiation entropy. When the entropy production rate within any solar energy conversion device is to be calculated, the incoming radiation entropy flux has to be known. In this contribution, first it is shown how the radiation entropy flux arriving on earth is to be calculated. Secondly, the interaction between the incoming radiation and the ...

  • A new type of solar concentrator employing a cone-cylinder combination

    Most conventional solar thermal radiation concentrators have some sort of symmetry which allows them to concentrate solar thermal energy for their operation. We report a new system that utilises the symmetry of a cone and a cylinder combination to simulate the concentration of solar radiation on a ring containing a fluid (water). A halogen lamp is used as the source of radiation to simulate solar ...

  • Flat absorbers with trapezoidal cavity for Fresnel reflecting solar concentrator

    The absorber is a very important component of the solar concentrating collector. The overall heat loss coefficient of the flat rectangular absorber and multi-tube absorber were studied experimentally. Both absorbers were coated with ordinary dull black paint. The heat loss coefficient was comparatively 4-11% lower in the case of round pipe absorber and increased with the absorber temperature in ...

  • The alternative to coal in South Africa

    With a desperate need for dispatchable generation, South Africa should be readily embracing CSP as a low-carbon, sustainable, base load energy alternative. So why do its energy authorities remain unconvinced? This question has formed the subject of Part 2 of the CSP Today South Africa Guide. London, UK October 11 2011 Forget green energy: while most nations are concerned ...
