Try It Without the Fan

My guess is that using it without the fan probably works just as well. It might take a few minutes or seconds longer to start flowing in the morning, but once there is enough temperature difference between the intake and the internal box temperature, the air will flow by itself (heat rises).

In fact, sometimes in passive solar design, a home will have a solar chimney effect (as if the home is inside the box), and the wind will get too strong and cause papers to go flying.

Hummm... I wonder if I should apply for a patent on a solar-powered home dust remover? Which reminds me that the design shown here is probably patented, assuming it is the same design as the one owned by the company in Canada.

What do you think?
