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.
it has to be hot to work, so why would you need heat?
I keep saving these things in case of the apocalypse but I just realized there won’t be any electricity and I won’t be able to access my computer!!! LOl!
Bet this would be lovely for a chicken coop in the winter.
neat! <3 =)

What moves the air into the house? No fan or anything? Or did I miss that part?
Heat rises and you do too I’d bet. I’ve seen more efficient with the same funds. $50 , we should make it a BTU challenge contest.
I made one last week and sealed the window, must have done something wrong because it doesn’t work.
So Rich, my friend
Where do I get one?
