Using a normative framework to explore the prototyping of wireless grids

The capacity for normative frameworks to capture the essential features of interactions between components in open architectures suggests they might also be of assistance in an early, rapid prototyping phase of system development, helping to refine concepts, identify actors, explore policies and evaluate feasibility. As an exercise to examine this thesis, we investigate the concept of the wireless grid. Wireless grids have been proposed to address the energy issues arising from a new generation of mobile phones, the idea being that local communication with other mobile phones, being cheaper, can be used in combination with network communication to achieve common goals while at the same time extending the battery duty cycle. This results in a social dilemma, as it is advantageous for rational users to benefit from the energy savings without any contribution to the cooperation, as every commitment has its price. We present a necessarily simplified model, whose purpose is to provide us with the foundation to explore issues in the management of such a framework, policies to encourage collaborative behaviour, and the means to evaluate the effects on energy consumption

Addressing long-term challenges in energy for sustainable futures by applying Moonshot Thinking

The rapid and exponential changes in our world require the education of engineers who can develop solutions to future and long-term challenges such as climate change. Exploration and innovation methodologies such as Futures Thinking and Moonshot Thinking have the potential to equip engineering students with useful tools and skills to build sustainable futures. To this end, the InnoEnergy MSc Energy for Smart Cities programme at BarcelonaTech (UPC) has developed a challenge-based learning (CBL) course that applies moonshot thinking to tackle major energy problems. This paper presents the methodology refined over three years of implementing the CBL course with second-year Masters's students in Energy Engineering. The course begins by constructing a narrative working future using exploratory tools from the Futures Thinking methodology. Breakthrough technologies are introduced, and their disruptive potential is analysed. Students then define a long-term sustainability and energy problem and use various ideation methodologies to develop a solution. Using technologies such as 3D printing, artificial intelligence and open-source electronic prototyping platforms such as Arduino, they build a minimum viable product (MVP) and develop a business model. Finally, using an agile approach, students must design future iterations and analyse the potential exploitation of their solution. This subject equips students with the necessary skills to address complex energy and sustainability challenges, and the course has proven effective in preparing students to apply their knowledge in practical, real-world settings.Objectius de Desenvolupament Sostenible::13 - Acció per al ClimaObjectius de Desenvolupament Sostenible::13 - Acció per al Clima::13.2 - Incorporar mesures relatives al canvi climàtic en les polítiques, les estratègies i els plans nacionalsObjectius de Desenvolupament Sostenible::13 - Acció per al Clima::13.3 - Millorar l’educació, la conscienciació i la capacitat humana i institucional en relació amb la mitigació del canvi climàtic, l’adaptació a aquest, la reducció dels efectes i l’alerta primerencaPostprint (published version

Cloudy in guifi.net: Establishing and sustaining a community cloud as open commons

Commons are natural or human-made resources that are managed cooperatively. The guifi.net community network is a successful example of a digital infrastructure, a computer network, managed as an open commons. Inspired by the guifi.net case and its commons governance model, we claim that a computing cloud, another digital infrastructure, can also be managed as an open commons if the appropriate tools are put in place. In this paper, we explore the feasibility and sustainability of community clouds as open commons: open user-driven clouds formed by community-managed computing resources. We propose organising the infrastructure as a service (IaaS) and platform as a service (PaaS) cloud service layers as common-pool resources (CPR) for enabling a sustainable cloud service provision. On this basis, we have outlined a governance framework for community clouds, and we have developed Cloudy, a cloud software stack that comprises a set of tools and components to build and operate community cloud services. Cloudy is tailored to the needs of the guifi.net community network, but it can be adopted by other communities. We have validated the feasibility of community clouds in a deployment in guifi.net of some 60 devices running Cloudy for over two years. To gain insight into the capacity of end-user services to generate enough value and utility to sustain the whole cloud ecosystem, we have developed a file storage application and tested it with a group of 10 guifi.net users. The experimental results and the experience from the action research confirm the feasibility and potential sustainability of the community cloud as an open commons.Peer ReviewedPostprint (author's final draft

FSEA 2014 – Proceedings of the AVI 2014 Workshop on Fostering Smart Energy Applications through Advanced Visual Interfaces

It is with great pleasure that we welcome you to FSEA 2014, the AVI 2014 workshop on Fostering Smart Energy Applications through Advanced Visual Interfaces. This workshop focuses on advanced interaction, interface, and visualization techniques for energy-related applications, tools, and services. It brings together researchers and practitioners from a diverse range of background, including interaction design, human-computer interaction, visualization, computer games, and other fields concerned with the development of advanced visual interfaces for smart energy applications. FSEA 2014 is the result of the efforts of many people involved in its organization, including our programme committee, and others who have assisted us in putting this workshop together
