Low cost solar conentrators

  We would like know if there is anyone interested in purchasing solar
concentrators.  We are considering manufacturing a line of parabolic
type reflectors (round & linear) Our objective is to produce low cost
concentrators from 11" to 44" in diameter & linear from 2' to 10'

 We hope to keep within a price range of $25 to $200 usd for round
types. Linear types are in development and price range is yet to be
determined.

 11" prototype will produce smoke on a piece of MDF in less than 30
seconds.

 Please feel free to respond by post or email if interested. There is
no obligation, if you respond. We are only assessing market interest
at this time.
Thanks,  Bob

Depending on specs, I might be interested in both types. I'd be
particularly interested in dimensions of focal area, materials used, and
expected longevity.


NBD. My 4x8 parabolic trough produced smoke on a piece of fir in less
than 3 seconds. The more important question is how well it'll perform
ten years later - and I don't have great expectations for my
rear-silvered 3/16" polycarbonate mirror. You might address shipping and
whether these can be shipped compactly (knocked-down) for assembly by
inexperienced folks at point of use...


Did. Don't feel any obligation. Talk to us!

Well, it's been almost a week. Just in case they don't come back or
didn't find enough market interest, I'll offer a set of seven
CNC-machined plywood ribs for US$99.95 - the set is suitable for use
with a sheet of 4'x8' mirror material to build a parabolic trough. The
trough I built with these ribs concentrates the light to a 3/8"-wide
line and produced a 724F temperature.

My offer ends when they identify themselves and post firm specs and prices.

Just in case there's anyone out there who wants even higher
temperatures, I'll offer a rib set for building an 8'x8' parabolic
trough for a mere US$249.95 - two of these sets can be combined to build
an 8'x16' trough. Shipping, of course, is extra.

I won't recommend building much wider than 8' because you might be in
danger of melting/vaporizing whatever you put at the focus. :-)

  You wouldn't have any plans for a flash boiler/heat exchanger
to go with that would you?
