Thai Solar Cooker: Cook Lookchin with the Sun

Easy DIY Thai Solar Cooker Project

Cook look-chins & hotdogs with the sun!

Here is a fun and easy DIY solar cooker project for Thailand. This solar look-chin or hot dog cooker really works! All you need are a cardboard box, tin foil, poster-board, and something to cook! Sunlight hits the tin foil and focuses its heat on the look chins or hot dog held in the center.

What do you need?

1. A cardboard box

2. Tin foil

3. Poster-board (or similar thick paper board)

What to do?

1) Select a long narrow box; the longer the box the more heat collection is possible. Trace identical curves on opposite sides of the box. Make sure the curves are centered and straight as seen in the picture.

 

 

 

2) Cut out the curves with a utility knife. Then measure and cut a piece of poster-board that will fix perfectly against the top opening of the box, like seen in the picture. Attach the poster-board with tape beginning at the center and working toward to edges.

 

 

 

3) Cover the curved poster-board with glue and apply aluminum foil with the shiny side facing up toward the sun. Start in the middle and smooth toward the edges. Try not to wrinkle or fold the foil; you want it as smooth as possible.

 

 

 

4) Use two scraps of cardboard taped to each side as supports. Place your solar cooker outside under the sun and find the focal point. The focal point will be the brightest spot on the tin foil. This is where the light/heat is concentrated. Place your supports opposite the bright spot and punch a hole in them for the skewer.

Insert the skewer and attach your look chins or hotdog. Cook until finished and enjoy your dinner!
