In the do it yourself category we have Ma Yanjun, a farmer in Mizhi county, Shaanxi province in China, that managed to build a solar water heating system using empty beer bottles. The reason he did it, was to allow his 73-year old mother to take a warm bath every day.
Since there was no warm water in the area and he couldn’t afford paying the big bucks for a hi-tech solar panel, Ma had to be innovative and instead of photovoltaic panels he used dozens of beer bottles. He finished work in 2006 and ever since, he attracted the envy of 20 other local farmers, which needed his help and skills.
We don’t care who emptied those beer bottles and want to congratulate Ma for his achievement.
