Pop Can Solar Furnace 2.0 - Part 1

I finally found time to assemble my second Pop Can Solar Furnace! I'll be posting step by step instructions this week, as well as reporting on it's output as the week goes by. Here's hoping for sunshine!

What makes this pop can solar furnace different from the last one is pretty simple: it's stronger, more stable, and has a custom fit in a vertical window.

Materials

1 piece 1/4" thick pressboard, cut to fit your window

4 pieces pf 1x3 or 1x4 cut to fit the dimensions of your window

approximately 100 pop or soda cans made from aluminium

1 can high-heat black bbq paint

a handful of finishing nails

Assembling the box

First, cut all the wood to build a frame that will snugly fit into your South-facing window. In this case, I used a mitre saw to create nice 45 degree corners, but you could use a simple butt-joint if you didn't have a fancy saw. Using the finishing nails, tack it together and test your fit before moving on to the next step.

The goal here is to create a light weight frame for your furnace that will look attractive from the inside of the house.

Of course, I recommend you use recycled materials whenever possible for a project like this.

Next up, place and painting the cans. (Go to step 2.)
