Hi Disqus,

I set up a Facebook profile where I can post my pictures, videos and events and I want to add you as a friend so you can see it. First, you need to join Facebook! Once you join, you can also create your own profile.

Thanks,
Adam

At a time when we all need to reduce our use of fossil fuels and energy obtained from them, and when too many "trendy" people have made wood-burning prohibitively pollution-intensive for modern, densely populated neighborhoods, any affordable source of non-polluting, renewable energy has to be welcome. And you can't get much more affordable than free!

Convestion works like this. The unit is all one temp when first placed in the sun. The black pop cans heat up quickly and thus also the air in side them. The hot air rises to the top naturally thus causesin cold air to be drawn in the bottom of the frame to replace the hot air that is rising and leaving through the vent at the top. This cycle will continue as long as the sun keeps the cans hot.

In a sense, this looks like a variation of a trombe wall without the thermal mass. Very clever! If you wanted to use this for cooling, you could vent the top outside instead of inside and draw the air from inside your structure, first routing your air intake down into the ground, aka 'solar chimney'.

I work with The Mad Housers, and we're definitely going to look at this ingenious low-tech, low-cost passive solar heater.

I always thought if you parked a black junk car next to the house , in the sun and ran a dryer vent hose over to a hole in the wall......

PLEASE send me the plans, I love this, and I work with hardowrking families taht just could use that extra boost - what a great idea for a community project! propertrm@live.com

Could you please send me the plans as well. Thanks a bunch in advance. cladyfan@aol.com

you could possibly use muffler tape. I think that would stand up to the heat?

Wow! I love that idea and it's nice that you want to help other people who can't afford heat. I'm going to try it!

IM RETIRED AND NEED SOME FREE HEAT can you send some plans?

If you can modify your design to accommodate some heat sinks (bricks, sand, etc), then you could likely reap another hour or two of heat out of it, maybe more.

Fascinating concept. Living near Lake Michigan lake effect clouds always present challenges for harnessing solar energy in the winter.

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.

Re: Free Heat From An Old Window And Some Soda Cans.

Guest — Sun, 27 Dec 2009 12:48:29 -0000

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

Awesome idea.
