Research/Design Energy Harvesting Categories
Intro: Categories of Design Projects using Energy Harvesting
Design projects about or with energy harvesting are abundant. For discussion it is needed to categorize and select a reduced number of examples. The categories chosen are closely related to the curriculum structure of the WdKA. The goal of this categorisation is to produce examples which will have a direct appeal for the student groups studying in these domains. This categorisation will be combined with two other ways of ordering these projects: ordering on the amount of energy involved and ordering on the way the energy is generated. These three orders will create a three dimensional possibility space.
Commercial Projects
- Designers are involved in projects with the aim of generating commercially exploitable amounts of energy
Solar Bike Road
The idea is simple: for generating solare energy flat surface is needed. Roads are flat surfaces, why not use roads for energy production? At the moment several experiments are made to gain experience with this concept.
"SolaRoad is a pioneering innovation in the field of energy harvesting. It is a unique concept, which converts sunlight on the road surface into electricity: the road network works as an inexhaustible source of green power. SolaRoad is sustainable and can be used in practice in many different ways."(Citation from site)
"De opbrengst van SolaRoad, het fietspad in Krommenie dat zonnestroom genereert, is boven verwachting hoog. In het eerste half jaar is bijna 3.000 kilowattuur opgewekt." (Citation from article)
Comparison: "1 kWh kost momenteel (prijspeil 2014-2015) ongeveer € 0,23 per kWh stroom.". Dutch current cost of 1 KWh = 0.23 euro. Profit of solar bike road: 3000*.23 euro = 700 euro. Investment of the projct: 3000.000 euro for 70 meter of solar road.
Critical remarks about the idea of using roads for generating solar energy are coming from technicians: [ ] [ ]
sustainable dance floor
"The Sustainable Dance Floor modules flex slightly when stepped on which creates a movement that can be transformed into electric power by a small internal generator. Each module by the size of 75x75x20 cm can produce up to 35 watt of sustained output. Between 5-20 Watt per person." (Citation from site)
Solar Cells in Architecture, Central railwaystation of Rotterdam
In this case the architecture is having a roof of solar cells. This use of solar energy is hidden in the architecture and could in principle be added to all roofs of buildings without the interference of a designer. This is on the edge of what is the research subject of "Design and Energy Harvesting". The project is great for comparisons.
"De zonne-energiecentrale van 130.000 zonnecellen levert naar verwachting 340 megawattuur per jaar. Ruim voldoende voor de energievoorziening voor de roltrappen, verlichting en de liften op het station en vergelijkbaar met een energiebehoefte van 100 Rotterdamse huishoudens. Het zonnedak realiseert een CO2-reductie van ongeveer 8 procent." (citation from site)
Comparison: 340*1000kWh = 340 * 1000 * 0.23 = 78000 euro's, using the same data as the solar bike road.
Social Projects
- Designers are setting up many local small scale projects for example for people living in Africa
Art - Autonomous Projects
Awareness projects
- Designers are creating interesting game situations for children to gain intuition into energy
- for example: Energy Bugs
Research Projects
- research Designers are investigating possibilities of energy harvesting in clothing and devices and probing the social consequences
