Solar Heater With Plastic Bottles

When I started studying solar energy, I could not understand anything, I was going to my classes and everything but I did not understand a 100%, it was until I saw how things worked, when built them, that I could understand how solar energy worked.

This same thing happened to me the first time I was told that we would build a solar heater with plastic bottles; I could not imagine how it would be until I saw it built.

That’s why I post this short video which briefly explains the operation and we can see how it works “live”, when I started this would have been very useful and that is why I want to share it with you.

Share and Enjoy:
