Here's something I've been wanting to do for awhile now. This is a heat box that attaches to the outside of your home or work shop. It's FREE energy! I've done a lot of research into these and they generate a lot of heat when the sun is shining. I have seen others getting results of a 150F exhaust temperature when it is only 25F outside! Who cares if they only produce heat on sunny days. Free is free. On those days your heater won't be burng gas, or your electric base board heaters won't be on, or you will save firewood.
Here we go
I had my 50 year old windows replaced last year. I made sure to keep the large windows as for sure they don't have any UV protection on them. You want the full power of the sun to shine threw.
I began by dismantling the windows. One did not survive
. I then repurposed the wood keeping in mind that the windows would fit right back in. I used foil backed insulation for the back and all sides. You don't want any heat escaping.
I'm using the latest design which implements the use of aluminum screen door mesh. It's that simple. The original design from years ago use's pop cans. That evolved into down spouts, both very time consuming. It was later discovered that unrestricted air flow is what works best.. enter the screen door design, and it's super simple in comparison and allows a great amount of airflow. The early designs for sure generated a ton of heat inside the box.. but it was useless heat cause they couldn't get heat out of the box and into the house quick enough. A 12v DC 6" computer fan will be used with a small solar power panel for power. It will be activated with a thermostat so that when the sun goes down.. it doesn't keep running and pump cold air into the house at night or cloudy conditions.

Wooden frame to hold 3 layers of mesh. Some people use 2 layers and others 4 layers. I went down the middle.. in anycase they all had great success. -

Screen just sits in there loose. It will expand and contract many times a day, so don't hard mount it. Notice how its tilted. Cold air comes in from the bottom and has to pass threw the screen to get to the exhaust.
