He is just a farmer from Ma Yanjun, China but he already become one of the famous man in his country. The story begin when he want to supply hot water for her mom’s bath. I’m sure his mom will be proud of his invention. His own solar-powered water heater out of beer bottles and hosepipes….!!

Ma’s invention features 66 beer bottles attached to a board. The bottles are connected to each other so that water flows through them. But how does it work?

Sunlight heats the water as is passes slowly through the bottles before flowing into the bathroom as hot water. Ma says it provides enough hot water for all three members of his family to have a shower every day.

For your information, more than 10 families in the village have already followed suit and installed their own versions of Ma’s invention. [via]
