Bringing electricity to this population will require an unprecedented use of mini-grids and standalone solar home systems. This analysis compares household demand for power in rural Africa with the estimated cost of supply from off-grid systems. Based on current conditions, it will be difficult to meet international goals of providing households with a basic level of power at an affordable price. However, a large percentage of households should be able to obtain enough power to meet their highest priority needs - lighting, communication, and entertainment. Refrigeration will be a tougher challenge. Solar home systems (SHS’s) will likely meet the needs of many more African households than mini-grids. For small household loads, they are a cheaper option than mini-grids, particularly pure solar mini-grids, and face few of the regulatory and financial barriers that have stymied mini-grid deployments. Technology developments, such as cheaper battery storage and more efficient appliances, could provide greater advantages to SHS’s. Biomass currently accounts for 90% of household primary energy demand, and there should be significant potential for its greater use for power generation.","PeriodicalId":136014,"journal":{"name":"Sustainable Technology eJournal","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132281101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As Blockchain technology and the IoT begin to disrupt multiple industries, utilities and individuals are both presented with the opportunity to capitalize on the fastest-growing energy source. Therefore, the purpose of this paper is to investigate the current pain points facing the solar power sector and discuss existing blockchain-based solutions to mitigate said issues. \u0000Approach: Online research and Internet-based resources were used to explore the potential use cases of blockchain to initiate the permanent shift of the energy industry towards renewable resources. \u0000Findings: The findings identified several blockchain-based applications such as smart metering, peer-to-peer trading, EV charging, renewable cryptocurrencies, wholesale trading and settlements, energy access, blockchain labs, and various decentralized energy applications. Results demonstrate the high potential for utility companies to benefit from this technology while also considering limitations of the applications. \u0000Discussion: It is likely to be over a decade before any significant progress is made in the renewable energy sector, which can be mainly attributed to the high cost of energy storage and the inability to conduct large-scale research-backed pilots. \u0000Value: There are several publications on blockchain and energy which focus on specific applications within the industry. This paper provides value through its comprehensive list of existing pain points in energy production, storage, and distribution, while also exploring the most prominent use-cases currently aiming to tackle these issues.","PeriodicalId":136014,"journal":{"name":"Sustainable Technology eJournal","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126341914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The new biomaterials used have special mechanical and biological properties for which they should be extensively studied for their use for various advanced biomedical applications. The new hybrid material has been prepared using 2 and 5% by volume of detonating nano-diamonds and poly (hydroxy-ethyl-methacrylate) hydrophilic. Both the mechanical and biological properties specific to the nanocomposite are hybrids in nature. The paper presents the analytical procedures of the hybrid material and the preliminary mechanical characterization. This class of hybrid materials has a high potential for biomimetic, osteoconductive and osteoinductive applications as active bio-mechanical bones for increasing osteoblasts and differentiating stem cells. At the same time, these hybrid nano-composites possess a much improved mechanical strength that exceeds the mechanical deficiencies of the hydrogels traditionally used for bone regeneration and can be applied as an osteoinductive coating for metal trabecular scaffolds. Micro-trabecular metal structures coated with active and osteoinductive biomechanical ceramic-polymeric biomechanical scaffolds are proposed to recreate macro and micro-distribution of bone stresses and deformations.","PeriodicalId":136014,"journal":{"name":"Sustainable Technology eJournal","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131399920","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Innovation pathways depend on how actors, interactions, and variables affect the origin of innovation; the uptake of the innovations (adoption and diffusion); the impact of this diffusion on upgrading, structural change and inclusion; the complementarity between these processes; the potential trade-offs between structural change and inclusion. The paper offers a set of novel applications to test the proposed framework, through different examples of innovation pathways: (a) international technology transfer, based on an extensive systematic literature review; (b) product and process innovation in the dairy sector in Kenya, based on a secondary case study; (c) an organisational innovation in the provision of antiretroviral treatment in Mozambique, also a case study; (d) a systematisation of metrics and indicators of innovation, structural change and inclusion and an empirical exploration of their relationship. The learning generated will support a multidisciplinary, multi-methods research agenda to map the dynamics around innovation, structural change, and inequality and generate an integrated platform of evidence on these processes. In doing so, we respond to the recently increasing demand coming from international institutions, inter-departmental research funds, NGOs and national ministries, for better knowledge to shape a more effective innovation policy for sustainable and inclusive development in low income countries.","PeriodicalId":136014,"journal":{"name":"Sustainable Technology eJournal","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127840964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
