Solar furnace?
My wife saw an article on these and wants me to build one to heat the basement. Anyone have any experience with them or in building them?

I was thinking of throwing together something like this.

I was tinkering with THIS ONE but now some well funded 'experts' beat me to it.

A good book on the building various solar projects is DIY Solar Projects by Eric Smith

RE: Solar furnace?
We bought 2 of these, and the fresh air Canadian design works well - but it cost $2500 for an 8 x 12' model. Cansolar, I believe. The 3x6' wall unit that recycles air from inside the house does nothing noticeable, and cost $1800. It does have a solar powered fan as well, so it will work when the grid is down, but since it doesn't heat anything, it doesn't matter.

The fresh air model, very good for tight homes burning wood, s no longer available for sale to consumers :-( The idea in the youtube video above is very good, and does not require a fan. Put it under a window and vent the top pipe into the house - heaqt rises.

I talked to several businessmen in the energy business about building these units, and NO ONE is interested. Everybody seems to think oil will go on forever....
