tracking solar cooker

shows a solar funnel cooker i
made. The solar funnel is not particularly well made (it was made just to
test out the tracking method). please examine the way it points and tracks
the sun.
Thank you

Seems like a great idea. Will evaporation make the bottles empty
faster in the outoors than indoors?

Would be nice with pictures and text, the movie is a bit hard to
follow at times.

is the followup. Much simpler.
Anyone interested in doing some pinhole research with 2 liter popcans?
Basically, you make a pinhole at the bottom and let the water drip out. It
drips out fast at first and then slower. There is probably a graph and a
formula that shows the weight at a given time in the emptying.
Also, if the can is left on it's side, the dripping will take a lot longer.
(Again, the formula will tell the weight at a given time).
Next stage is to ally those results with how the carpenter's square moves as
the weight is removed.
What we want is 3 hours of emptying coresponding to 45 degrees of angular
movement.
Anyone interested?

Clever but. . . With the need to be finely balanced combined with the size
of the funnel I'd think any wind at all would really screw things up.
