The warm summer months never last forever. Soon it’s time to look for a way to bring a little extra warmth into the home and this simple solar heater is a great project to do just that. It’s made of metal cans, steel or aluminum, and can produce a surprisingly strong and consistent airflow upwards of 140F.
Even on a heavy snow day you’re looking at somewhere around 75-85F.
Best of all, this simple project requires just a few common parts and many of them can simply be re-purposed from your regular recycling. Watch the project come together in the fully-detailed video on the NEXT PAGE:
He should have painted the cans black matte.

We made this in Junior high school some 40 years ago.. Someday it will catch on..
So why are we spending Billions on solar energy projects?

Put that thing in freezing weather sucking in freezing air and tell me how “hot” the air coming out is??
When we lived in Colorado a house on our street had a huge solar setup on their roof built out of aluminum cans between gl$#%&!@* panels.
@[100001564879732:2048:Jeffrey], @[100000692927854:2048:Patricia] , maybe a way to burn less wood next winter?
Might offset the hikes in heating costs from the killing of the coal industry. Good reuse of materials.
Simpler and cheaper, no cans. make a frame inside the box and stretch black aluminum window screen on both sides. Make stand-offs so it is centered in the box. It’s about the same surface area/heat output. For added efficiency, use a small solar panel and thermostatic switch. It will only run when the internal air temperature is high enough and the sun is out to add heat. My dad built something similar and even in freezing weather there was a significant heat gain.
