He used 44 cans of beer to make an appartus which provides heat FOR THE WHOLE HOUSE! (PHOTO)
The heating system functions in a way where the cold air comes in through the shaft on the panel, and in a well-isolated system it gets warmed by sun rays, explains Darko Milićević from the city of Paraćin, who invented a solar panel out of beer cans
Professor of Information technology and a mathematician from the city of Paraćin, Darko Milićević, used the old beer cans to make a solar panel which turns the outer temperature of -5 C into +52 C inside the house in a spectacular manner.

The panel is a small one because it is just an experiment, and it does not have enough power to heat the room completely, but Milićević claims that the "project is functioning", so here is an idea how beer enthusiasts can use the cans they have.
- During last winter I was searching online about different ways of heating. I found many different ideas, but this one grabbed my attention because it seemed to be pretty simple. I bought some plywood, Styrofoam for isolation, paint, and silicone. I had some breaks so it took a couple of months for the project to be completed. Before the next winter I placed the panel on the south wall of the house because the rays are the strongest there - says this creative professor.
The heating system functions in a way where the cold air comes in through the shaft on the panel, and in a well-isolated system it gets warmed by sun rays.
The air naturally goes up and it enters the house through an already-made hole in the wall.
- I started this project first with making a plywood frame 1x1 meter. Then, I placed Styrofoam around in the 3 cm width. I used black foil and made frames for cans which I had also painted in black. In this manner they absorb more sun rays. The panel has got 11 cans in 4 rows, 44 altogether. It is not expensive because the Plexiglas for protection is the most expensive. It costs around 2.500 RSD and should be put at the front side so that the hot air would not get out of the system. I do not count the cans as expense, so this heating system costs around 60 Euro, not counting the work - says Milićević.
A panel this small cannot heat the whole house by itself, but it is useful as an additional source.
- I took some measurement on 31 December. The outside temperature was -5 C, and hot air at the +51,8 C was going into my living room. Negative side is that the system only works on a sunny day - explains the professor, who already has more ideas.
Namely, apart from this solar panel, he made an authentic knife for slicing home-made pie, burek, a lot stronger than the one you can get at the stores.
Why exactly the knife, his wife Milka can explain.
- He has got creative ideas in many areas, and in the kitchen also. He is a specialist for making home-made piecrusts and different stuffing. He makes the stuffing out of mushrooms, soy, cabbage, and many other things so we need a good knife to slice those crispy crusts - says Milka.
When you think about it, there is a connection between these things because a home-made pie goes perfectly with beer.
