Presentation 6 – Storing sunshine with microgrids This presentation clearly articulates the dilemma facing societies where current sources of energy contribute to climate change, but renewable sources of energy are not yet able to replace current energy demands. The use of microgrids, either as stand-alone systems or as part of a larger grid, is proposed as a possible solution. Microgrids would utilise energy from renewable sources such as wind and solar and store energy in new generation NCN-PHI batteries for low light/wind periods. The author outlines some of the obstacles to implementation of the proposed system. These obstacles include a lack of funding for both research and implementation and the inefficiency of solar panels in converting solar energy into usable energy. Added to this are the potential adverse social and environmental effects of devoting land to large arrays of solar panels or the construction of dams to produce hydroelectricity. The material is well presented and referenced but could benefit from having less information on each slide. Slowing down the speed at which the spoken word is presented would make it easier for the viewer to assimilate the material. Overall, the concept presented provides a possible solution to sourcing energy and at the same time reducing impacts on the climate. Presentation 7 – Artificial intelligence: in the shoes of a health care assistant In an interesting presentation the advantages and disadvantages of artificial intelligence are discussed but without artificial intelligence being defined. While artificial intelligence is still a developing technology it already has been proven to be of value in medical diagnostics. And yet, this success has raised the question of artificial intelligence being used to replace humans in various roles. The paradox is raised that humans don’t like to interact with appliances employing artificial intelligence (robots) because they aren’t able to express emotions, but if emotions can be inc orporated into robots, then humans will be more convinced than ever that the robots will usurp the roles of humans. This may not happen because it seems that technically, it is extremely difficult to incorporate these human traits into robots. To enhance the presentation, care should be taken to ensure that there is congruence between the spoken word and what appears on the slide. The arguments relating to artificial intelligence would be further improved if the opportunity was taken to develop the arguments further by using all the time allowed for the presentation. Overall, the author raises some important issues relating to development and future application of artificial intelligence.

Presentation 10 – Sustainable energy future and resolutions This presentation promotes the sun as a source of energy that should be used to the greatest possible extent as it does not produce adverse effects as do other sources of energy. The use of solar panels on all single-storey dwellings is strongly supported and the extension of their use to multistorey dwellings is proposed even though such buildings have not been designed to accommodate solar panels. However, the siting of solar panels at windows and on balconies is suggested. A major limitation to the greater use of solar panels is that currently used solar panels are relatively inefficient at converting solar energy into usable energy. Development of smaller, more efficient panels is recommended. This new generation of panels, combined with modifications to the design of new multi-storey buildings could encourage greater use of these panels. The growing issue of recycling of old solar panels is raised as another limitation to their use. It would have been beneficial if the presentation was developed further to utilise the time available and was supported by more technical references. In addition, to assist the viewer it would be valuable if the material presented on the slides coincided more closely to the spoken word. The presentation promotes a novel solution to the growing problem of providing energy to high density environments.
