Ragged edges

Bit off topic, but here's the solar panel (tracking parabolic mirror etc) I made a few years ago:
Got any pictures of what you've made?

Jonathan, very nice mirror. Does it have sun tracking system ??
Minnican, yes I want to see some pictures as well :) Very interesting subject

Yes it does - that's what the small PV on the top right powers. There's a small geared motor with a linkage to track the mirror. The mirror rotates on bearings placed around the focal pipe. You can just about see the temperature in that image - that's in Celcius. I've seen about 160C on it. I will post a better picture later when I've found it.
