Yesterday's Technology Today! Beer Bottle Solar Panels

Not everybody gets hot water when they want it. Ma Yanjun, of Shaanxi Province in China, was a farmer with a cold family. So he did the only logical thing one could do in such a situation: he built a solar panel out of beer bottles and affixed it to his roof. Now his family of four can each get a warm shower in the morning.

As The Beer Activist points out, "it's a great example of small-scale sustainable technology." Ma Yanjun managed to solve a pressing problem by using found materials and a little ingenuity. His solar panel depletes no resources, uses "unwaste" that would have otherwise been sent to a landfill, and it has even inspired ten other families in his neighborhood to do the same.

The science behind it is so simple that anyone can make one of these things. I couldn't find a step-by-step tutorial for this particular model online, but I did find instructions for making a hot water heater using reclaimed materials, as well as a great tutorial for a hot air heater. Of course, this might be a little more hands-on than most want to take on, but what a cool excuse to work your way through a case of beer!
