I made a new device for more easily forming parabolic dishes in august
last year. The "mechanical mathematician". Using a mechanical mathematician
is a major help if you make a tracking solar cooker. Initial guidelines
can be found at
http://groups.google.com/group/Sustainable-devellopment/web/tracking-solar-accumulating-barbecue
and video explaination can be seen at
Several videos are there
explaining the mathematician too. If you make one, please post pics of it
here or elsewhere. thank you Brian white

You have posted this in many groups repeatedly. The proper way is to
put multiple groups in the to box so that only one message is stored.

Multiple reasons not to multi post, but to cross post instead.
Multiple posting splits and seperates the discussion across many groups.
Are you even reading this group? Multi posting inevitably annoys the
regulars, and that is enough of a reason.
On another note, the OP has an interesting point on using a fraction
of a parabola. Of course we all do as they are infinite, but
instinctively we would use a symetric section rather than a section that
wouldn't shade itself and a section with easier geometry.

I am here to explain a few new concepts. I really do not care if regulars
get offended.
How often does something new come along in solar thermal? Not very often at
all.
And people recoil when it does!
I think the most successful solar cookers in the world are the Scheffler
reflectors. I do not know how they work, but I bet it is similar to my
proposal.
Only difference is that you need to be a mental wizard to make a scheffler
solar cooker, and mine can be done by ordinary joe soap or perhaps even
someone who cannot write.
With my proposal, you can easily track the sun either manually or with a
motorized telescope tracker and your focus remains fixed on the cooking
spot all day, heating it up all day for evening cooking.
And you can build your parabolic dish from scratch too.
Thats a hell of a big deal actually.
Also, it is many times easier if you do not! do a symetric section of the
parabola with my proposal.
Please get symmetry out of you head with parabolic solar cookers.
It is preventing people from making a leap forward.
I put this in solar thermal because it belongs here.
Make fun of it or get offended if you wish.
Be true to your nature.

This has nothing to do with your subject matter, but rather your
method of posting.
It isn't a big deal. People here are typically not the ferocious
bulldogs, as in some groups.
