Solar Heating
I was going to raise this in the wood heating thread but thought maybe a new post.
I don't know if this is worthwhile so I put it up for comment.
The basic idea is we build a box in glass, probably clear plastic...old windows..whatever such that we have a compartment, how big not sure yet...in there we lay insulation and lay about rocks, painted black maybe...a pipe of what diameter I am not sure runs to the house ...ideally the box is below the house and the hot air in the box will rise to the house however I expect small solar powered fans would be needed.
So the rocks heat up and warm air pumped into the house.
Now tell me why it won't work...
