Hemispherical Solar Concentrator?

I'm looking into experimenting creating a sort of hemispherical solar
concentrator. Perhaps some of you out there may have some words of
wisdom or ideas for me...

Looking something like:

| o |
\ |=/=== b
 -|-
  |
  a
1. Lightweight plastic(?) hemisphere - possibly some sort of sphere
that might be cut in half.
2. Some form of reflective coating?
3. Small copper ball (o) attached to copper tube/wire (o-a)
   dropping thru hemisphere.
4. Clear plastic(?) tubing(?) (a-o-b)

Experiment is to heat water in tube (o-a) to cause thermosyphoning
from cooler water below (a) to be heated and flow out thru (b).

Any suggestions for parts/information/etc much appreciated.
