A simple solar heater that is cheap and easy to make. When there is direct sun on the unit it produces heat like a hair dryer.
According to the creator it produces a stream of air of around 120 degrees.
Some suggested tips for improvement:
– Make sure your black paint is matte so it doesn’t reflect the sun.
– The air moves by convection, however, you could add a small computer fan on the outlet and wire it to a 12 volt solar cell the unit to control the air rate.
– The intake size could be adjusted to control air rate as well. Making the intake smaller will give the air time to heat up while passing through the dryer ducting but it will slow down the rate of air flow. You can run it hot and slower or with more air and not as warm.
– A flat plate could be added between the intake tube and inside wall up to a little pulley inside the house. You could then adjust the air rate like this as well and have an on/off option.
– Add insulation to help maintain heat running through the system. Could prove vital for very cold areas.

Steve, heat usually rises, but physics says heat goes to cold.
Tina Marie Cook, this for your pool
Rotflol, I just got up and as soon as I saw this I watched the whole video thinking I’d make one for my pool and then I checked my notifications and clicked on one that said Lisa tagged you in a post. lol and look what you said 😉 Imma redneck too!
They also have one from alum.cans, Fellow at work made it, pretty cool.
Ono mabe you and Chris should start considering this kind of stuff to reduce your bills. I’ve seen so many cheep easy stuff to make.
But Obama
Why would this create any more heat than just adding a second window to the room?
I have to laugh when I keep seeing “so called green” inventions to save you money. This is a joke! It will only work on mildly cool days. On cold winter days the sun can not heat up the air inside the box to a temp that is warmer then your house. It would make you house colder.
