I saw that aluminum cans can have many uses in the home, in particular by transforming them into decorative objects.
This time, aluminum cans find their home a practical role in forming, with little skill and patience, a solar panel. It requires minimal knowledge of thermodynamics and to turn aluminum cans into a passive device that propagate energy.
More specifically, solar heat is transferred inside the house thanks to aluminum cans that are a good thermal conductor. This solution is ideal for those who live in isolated areas but also in urban areas can be an effective measure to save money. Below are some steps a guideline to build a solar panel from aluminum cans.
Make sure, first, that your home is well insulated, otherwise any such effort is useless. First of all, build the framework to fixed in it the aluminum cans. This framework can be easily constructed of plywood 15 mm while the front will be used for 3 mm thick plexiglass. Over the layer of plywood inside the frame, you will use rock wool to insulate the structure and block the heat loss generated by aluminum cans.
After you have built the frame, wash the aluminum cans with warm water and dishwashing liquid. Let them then at least two hours in hot water to get rid of all smells content that you have, then rinse them all with hot water.
Drill wide holes in the botom cans similar to those in the upper dose that has already without chiping the lower edges, where doses will be leveraged to create and transmit a continuous body heat more easily.
Importantly, this system does not give heat produced and therefore it is recommended to use hot air stream as long as the sun shines in the sky. Otherwise, turn the two fans at the base of the system because they will pull warm air from inside the house and so the temperature will drop.
