Has anyone built one of these?
(There are a zillion videos about this on YouTube- here's one to get you started.

The commercial models cost $2800, and I'm sure we could build one more cheaply than that, but I'm curious as to how much we should plan on spending and well they work. They say that the 240 can model will heat 1000 square feet.
Since we have 10c can deposit here, I think it would be more cost effective for us to use 3" aluminum ductwork.
We have a well insulated, 1500 sq ft house with great Southern exposure, a pellet stove as an additional heat source, and a 600 square foot old Michigan basement.
I would love to hear any ideas or experiences.

Here's an interesting link that compares several types of passive solar heaters:

I was a little surprised that the black screen one had the best results! Sure would be the fastest to make.
Tons of solar projects on that site, too!

The intense rays set the sails on fire and staved off the invasion. Since Archimedes, many of the most progressive thinkers have harnessed the power of the sun. The effect is similar to that of our atmosphere which traps sunlight and warms the earth.
