Cool piece of engineering there. I don't understand how the convection process works though. How does it draw in the air without a motor/electricity? Also, do you have a backup for overcast days?

Ah Jester, but just think - all that hot sun in India could equal lots of "free power" if its hooked up right...

Great idea but I don't know when it gets cold outside do you leave the gadget in the sun outside? Will that work? I am not the smartest cookie in the box. So please don't think my question is stupid.

Great idea. I'd like to try something like this when I get a place of my own.

I like the means for the supplies, but you must be making one to heat the mall! I usually can supply the cans in a few days, nothing like a few cans away from a beautiful day! FLH jack

Great project, I have looked at several and this seems to be easiest and most efficient, do you have any more detailed plans of this? Thanks if you can forward any.

This seems like a very worthwhile project, I have seen others but this seems to be the best so far. Do you have any dimensions or other info for this project?

Thanks

Awesome. I have been trying to think of a good way to heat our small house here in Miyako. It is sub tropical so it doesn't get to cold, but winter time can get a bit chilly. Something like this might work pretty good considering we do get a lot of sun.

hey parker,
how much does the heat cost?
that's right, it costs nothing.
it is free.
you're confusing the conversion of energy, which is clearly happening here, with the cost in dollars of said energy. The energy is not being created from nothing, however it is not being paid for. hence it is free

you really need a life, this guy has made this awsome thing and all you can do is preach on what he should be calling it. 'nor should others be aloud' ALLOWED i think is the proper grammer here, im sure a 12 year old would have picked up on that.

Too funny Deanna. I tend to ignore those who correct me when their corrections are full of grammar and spelling mistakes. :)

If you're going to be an intellectual snob, at least use the correct word: I think you mean "allowed," not "aloud."

My Father-in-law died in 1985. He was a retired high school shop teacher and sort of a tinkerer, although I never knew him. When cleaning out his garage 25 years after his death I ran across a device, the function of which I was not clever enough to deduce; until I saw this! It was so similar to this that I am sure I now know what it was.
His was about 30"h x 60"w x 3"d thick. The sides, one masonite and one aluminum were painted a lime green. Pop cans were cut in half and attached to the aluminum side, with pop rivets as I recall, several inches between them. Also attached to the aluminum side were 4 baffles also made of aluminum, that ran not quite the width of the box, dividing it up into 5 areas approx. 12" x 30". The cans were all attached within the center 3 sections. Two regular floor heat registers, one at each end and both on the masonite side allowed for air flow; one vent had a computer cooling fan attached.

I have several photos I took while dismantling it which I would be willing to share with you if you like. Let me know.

Thanks for solving the mystery!

I'm just wondering if your idea would work for a small greenhouse? Although being up north were we really don't get much sun light during the winter, I'm thinking there isn't enough sun light to produce much heat.... But the concept is very good.

Anyone use this set with a greenhouse?

thanks

Please do not say "free heat" it is in no way free. you can not make nor can you destroy it you can
change its form from solar to thermal energy. I know what you mean but it peeves me and i find
if a 12 year old cant say it with out being lectured in school nor should others be aloud without being lectured.

Hello,

I have been experimenting with a freestanding version of a passive heater. It heated up pretty quickly, but now trying to figure out the best way to pipe the heat into my garage or living space. I used black pipe (the same as my heat chamber) but it was a bit clunky.

Anyone have this type of design and if so did you use something like a vacuum hose to transfer the heat into the living space several feet away? Just curious.

You can see some of my pics @ http://gravitygarden.com/powergarden/?page_id=11 if interested.

No, good comment. Even though it does say that, I didn't notice until I read your comment and reread the article. I actually came down here to post the same thing you did.

Do you think that if you make the cans larger at the bottom and progressive smaller as you get to the top it would be a little more efficient?
