built a solar cooker today

This afternoon we built a funnel-style solar cooker from household stuff & plans found at http://solarcooking.org/plans/funnel.htm.

The notion didn't hit us until the afternoon, so the first test ("How hot can we get this water?") was pretty brief. Performance seems impressive so far.

We used:
  • a cardboard JVC I'Art 27" flat screen TV box
  • about 2/3 of an ancient bottle of Elmer's glue & a roughly equal amount of water (way more than we wound up using) spread on the cardboard with a basting brush
  • Bell 1-qt jar, spray painted glossy black (because we didn't have any flat black on hand)
  • Reynold's Wrap Heavy Duty aluminum foil
  • box cutter (aka "utility knife")
  • printed copy of instructions (because returning constantly to the web during construction is just impractical)

My brother-in-law is pretty enthused & wants to take a crack at something similar, and I can't blame him. These puppies will be handy for recreation & the next inevitable hurricane.
