This is a solar air convection heater for my garage that is powered by the low angle winter sun. This is a second version of an earlier instructable I did; a solar heater for the chicken coop. The idea and design is from Mother Earth News (December/January 2007 Issue #219.

Ingredients:

  • 2×6 lumber
  • 2×4 lumber
  • 2×2 lumber
  • glass, plexiglass, or some kind of clear material.
  • black aluminum screen
  • caulking, paint, screws, lag screws, staple gun + other tools
