World-wide water scarcity, especially in the developing world, indicates a pressing need to develop inexpensive, decentralized small-scale desalination technologies which use renewable resources of energy. This paper provides a comprehensive review of the stateof-the-art in one of the most promising of these technologies, solar-driven humidification-dehumidification (HDH) desalination. Previous...

This paper reviews the stability, heat transfer efficiency and photothermal conversion optimization studies of solid-liquid phase change materials applied to water heaters. Suggestions prospects were proposed. The study shows that PCMs are mostly filled in tank, thermal storage devices or solar collector heater system with paraffin wax, addition can significantly improve performance. Further in...

Induction cooktops are a key element in home electrification. This paper presents new use of induction cooktops, which allows the preparation infusions directly ceramic mug. It is proposed design water heater with an immersible metallic load. The dimensions load allow its embedding small vessels. Despite being smaller than conventional inductors, has specific shape that it to efficiently receiv...

The operation of water heating uses a substantial amount energy and is responsible for 30% household’s overall electricity consumption. Determining methods reducing demand crucial countries such as South Africa, where supply almost exclusively electrical, 88% it generated by coal, deficits cause frequent blackouts. Decreasing the consumption tanked heaters can be achieved standing losses therma...
