The easiest is the black container method, such as the "solar showers " sold for camping. A guy tried to make one with a black plastic garbage pail, but it turned out that the weight of the water was too much for the pail, but he still wound up with something useful. He made 3 videos about it on youtube, here's the first: youtube.com/ watch?v= sewMS08Crlg If you want to see a really sophisticated solar hot water system (you will not be able to make this for school, but it will give you some idea of what people are doing in their homes), check out this house in Maine: solarhouse.com/ |
