Parabolic Troughs for DIY High-Temperature Projects

I've been exploring some of the possibilities of mechanical systems
powered by solar heat (there's a link to one of the projects below)
and would like to encourage other people to try out their ideas.

It appears that DIY activity/success is limited to by cost and
availability of materials and components. Judging from some recent
threads, it seems that persistance and determination are as important
as availability of funds.

I'm thinking of offering CNC-routed parabolic ribs for concentrating
collectors; and would like to find out if there's any interest. My
current software works from the thickness and width of the collector
material and can handle ribs up to 97" wide (long?). I can produce
wider ribs; but doubt that there will be many DIY types building
troughs wider than eight feet (or circular dishes bigger than sixteen
feet in diameter).

What do you think - is this something that'd fill a need or am I just
engaging in wishful thinking that other people might be interested in
exploring these kinds of applications?

You could contact these folks. They built DIY concentrators for people
in Africa as part of a program at MIT. It looks like they used routed
ribs.

Interesting project - but I don't think they'll make it to the "Top
10,000" list of sources for DIYers. :-)

 I would think a complete collection of parts should be offered. This
is based on: if people can cut and assemble the rest of the parts they
can usually cut their own ribs. Instructions, and each piece or a
complete kit could be offered for different levels of laziness and
skill.

 You might consider cutting and warping plywood sections for old C band sat
dishes.
Those make dandy solar collectors and people may need kits to cover those.
