Super good questions Here are some answers: Who are the low-end and the high-end target group? A third world village without access to fancy tools or paint, but lots of sun. High-end are urban dwellers who are unconscious of the amount of energy they waste using electric and gas ovens and that they could bake in their windows or on their roofs. This version should be very stylized, but simple. The message could be something like, the future can be beautiful and efficient. It could be a version that is built into a window. Like a window box garden, but instead a solar oven. What are their needs? Low end needs: cheap, useful oven. Gives them time to do other things while the sun does the work. There is no smoke or use of wood, so it is efficient. High end: fast, efficient, easy, and pretty to look at. Why do they want to use this? Low end: Gives them time to do other things. Previously villagers had to sit near the fire to make sure the bread did not burn and also inhaled toxic fumes. So now they can work elsewehre exhaust free and the bread will never burn. High end: They want to be more ecological. When are they going to use it? Scenarios... Low end: always High-end: always, maybe there is a portable/collapsable version for camping or just because they like the idea of it collapsing and they can put it away in winter when there is no sun. How big should it be? I think i described scenarios above that will help with this What is the perfect form for using the solar energy? Angels? Parabola's seem best. Less angles more efficient... There are some excellent designs online that we can work from What surface reflects the best? Flat and aluminum or some sort of shiny metal What black material transfers the heat the best? So far most models use black paint, but lets explore Should the manual for building be on the internet? Yes, manual online, free and open source, so people who use ours can write about their experience and make design suggestions. Could we do without buying glue and paint? Let's explore. Less is more! What size? For how many people? Size small to medium. Something that can be carried on one's back. 2-4 people is fine. |
