Solar reflector mounted on part of an office chair, might give people some ideas. Answered
http://www.youtube.com/watch?v=VhpwOD2gZLA is a video that shows a solar reflector that I made from mylar and an 8 by 4 sheet of corrugated plastic. I approximated a parabolic dish by cutting it to make cones.
I used bamboo to make it more sturdy. (Still needs more bamboo).
It is on a stand made from an old office chair. I intend to line up the mount properly and put it on equatorial mount but that will take a while.
It might be weeks before I have time to test the thing so here it is for now. I am slow at the experiment stuff. The dish started last september! And it took me that long to figure out how to keep the shape resonably tight.
So here it is at this moment. It will change a lot before it is finished but no reason not to show the current state of the project.
