solar heat from pop cans...

[Anny]

Interesting idea I just stumbled across, wondering if anyone has tried anything like this before?

Very interesting. I'd like to see if it works for my DH's shed also (so he can tinker around when its cold outside) might even work great for a small greenhouse. Thanks for the site and info.

I have friends who built a house into the side of a hill in the 70's.

They used tall beer cans to make a solar water heater. It still works.

thats just too neat. I wonder if it works. Crystal

The link won't work

Using solar power to collect heat is cheap and very effective, so much more
so than making electricity from it. If every house had one panel just to
make hot water we would save billions a year in fuel costs, reduce
pollution, reduce demand for foreign oil, increase the available supply
of natural gas(which we should be fueling our cars with), and more.


Remember we have two opposing forces at work here. One is Opec
and the oil lobby and the other is the environmental movement which
promotes misinformation about alternate energies.

Thermal solar, natural gas, man made gas, wind power, and nuclear
plants together can solve 90% of the US's energy problems. Clean coal is
ok too but does produce CO2 so if you buy into global warming it's
not that great.


Sorry, I tend to go nuts on solar posts.

sounds easy enough, my boyfriend has lots of computer parts. He also has a shed he can try it on.

Yep, made one similar to that a few years ago. It produced a surprising amount of heat. The only real difference in design, was that I used a sheet of aluminum behind the cans to give it some added thermal mass.

It was destroyed when a tornado passed near (about 100 yds away), this Feb. I'm collecting cans to build a new one for this winter. I'll try to post a picture when it's done.

Here's one almost the same. I'm going to build it this year for my coop

I'm wondering if you could utilize a similar concept to keep water unfrozen in the winter? We don't have snow or have that problem where we are but I just read the other post about ideas to keep water unfrozen during winter and then came upon this one and was wondering if doing something like painting the water storage section of the watering unit black (and making it like metal) would keep the water unfrozen during the day.

Just thinking outside the square.
