I posted about a week ago about my attempt to harness the sun for free heat. Well, today is the first sunny day we've had since then and I can report that it works. The sun as been on the panel for a few hours and I have 120 degree air (and still rising) coming out of the panel.
I'm excited!! Maybe I'll go ahead and build a full-sized one for the garage next (7'X25').

Awesome! When I land my own digs there will be many a DIY solar heater installed.

Did you check to see how much air came out via convection only? I bet you'd be surprised!

Right now it's only convection. I have the fan installed, but not solar (electric) panel yet. So the heat is coming out of the top and collecting in the coved area. I want to power the fan to blow the heat into the kitchen area.

This is what's happening now.

Late last night I stumbled onto some of the most reasonably priced solar electric panels I've seen.

Here: http://www.saferwholesale.com/category-s/554.htm

A 200W "do it yourself kit for $218.

Congrads. I love when DIY, cost savings and green intersect.

I wonder if a HF solar battery charger would have enough umph to drive a small fan?

Yeah, I think it would. It's only a 10 watt fan. But those chargers are like $80 or so. I'd hate to spend that kinda coin only to take it apart and destroy it. But it is looking like my best bet.

Holy hell, 120*. That's awesome. Clearly when I get a house I need to do this to some doors.

And that was with an outside temp of 18*.

That's pretty cool! The front door of one of my houses faced south, and we had a full view storm door. On a cool winter day the dark gray front door would get so hot you couldn't touch it.

Haha!
That was kinda the point of the post. I'd love to see others doing this. I dig free or near free energy. that's the whole reason I do the Greasecar thing. I'm not a Mercedes kinda guy, it's a terribly uninspiring car to drive (nice, but not inspiring) but free fuel (or energy) get's my wiggly bits all tingly.

if I owned this place and didn't rent it.. I would probably rig up something. It's funny, while my front porch faces north, I get great southern view out the back of the house. Even in winter, the heat does not come on much till it start to get dark

i kinda wanna try this at home. We have two windows in the garage that i could do this on and it would make a HUGE difference

Yeah, I think that's my next step now that I see it works. I'm thinking about basically doing a 6' by 20-24' panel on the garage. Oh yeah, some insulation too!
