So we hooked up a hair dryer to the inlet on the bottom of the box and used high-tech sealants to seal it fairly well. Then we used a piece of dryer hose, taped it to the outlet on top of the box and ran the other end of the hose into the window. Then we used old towels and a couple of socks to seal up the remainder of the window opening.
Just think about that for a minute. 130° air blowing at a constant rate into your house or wherever it is that you wish to duct it to, that doesn't cost you anything. How cool is that? Lots of guys hook up a thermostat to their solar heater and their fan only kicks on and blows hot air into the house when the temperature in the house drops below a certain preset level. I was rather impressed and it is definitely worth running a duct system through the window and hooking up a blower motor to circulate the cold air from inside the room, sending it outside through the box and then back inside once it works its way up through the box and gets hot. Stay tuned for further updates.
