Cheap quick optics experiments for solar reflector design
I wanted to explain compound parabolic reflectors to people but there was no suitable software to explain it so I made up this little set up instead. It might be a useful tool for many people.

Dome mould for compound parabolic solar cookers
Compound parabolic dishes differ from parabolic dishes in that they have an acceptance angle (a margin for error if you like) so they do not have to be exactly pointed at the sun or moved every few minutes. This is a very useful property!
This video shows how i made a mold for making parabolic dishes suitable for up to 3 hours of solar cooking before moving the dish. The mold can be used with whatever sheet material is available to make the dishes.
