Building a Solar Can Heater (Window unit)

This is a small window unit solar passive air heater I made as a test to see how they worked. I am currently working on a big version of this for suplementing my homes heat this winter.

Great video man! I'm not sure where you live but in winder does the unit produce the same heat in the winter as in this video? Keeping it in full sun both in winter and summer.

@mat2dong yes it does i build a huge unit to replace this one though works great.. im producing on average 150 degree heat during the day off the large unit.. the house is cozy!

i'm looking to make one myself, just curious what u r using to power your fan? i see a red wire but i can't see where it goes and i don't see any solar cells anywhere to power it. would appreciate if you could let me know, its starting to get colder here where i live (by Canada) so the sooner i get started the better.

great job by the way.

@msguit Im using a 12 volt DC adapter i bought just clipped off the tip and shrink wrapped the wire together using wire sleeves. Its a 12 volt fan.. i did the same thing on my larger sliding glass door unit.. i just finished a huge model im using a large 12 volt fan powered via solar panels. ill be uploading that video next week.

@nx2overide, thanks! I think I may give this a try over next winter:)

You are the only person I've seen yet that has offset his inlet and outlet holes. Good job

I like the video but what is the product name of that little fan? What is it called exactly? thank you

[msguit]

i appreciate your quick response. it would be nice to have a video of the electrical aspect as i and others are novices at it. i'm going to sound dumb here. doesn't the adapter need power? i understand now how the fan is working thru the adapter but guess i didn't know they had self-powering adapters. is it something you can get at radio shack? i bought 2 little fans for the fins & motors and was going to use solar cells but if i can use adapters i'd go that way.

thanks for your help.
