90 degrees and no power. Need solar fans or something else.?
Where can i find solar indoor fans? I am not referring to Attic fans. My family lives in Africa where they have power shortages that last for 2 weeks or more.So i want to get them a couple of solar fans. Something bigger than the portable fans. If you have alternative ideas please give me your suggestions?
A solar fan is a fan powered by sunlight. I found some portable ones, but i wondering if i can find something a bit bigger.
There is a project that several groups at GVSU have been trying to perfect for a couple of semesters now involving a fan that operates on hanging weights. It is difficult to describe in words, but basically a gear reduction slows down the speed of the dropping weight so that it lasts for at least a half hour or more on every "charge". The system they're working on is being designed for similar applications in Central America, and the prototype has been built using mostly discarded parts: used rebar, old fabric, bike sprockets etc.
