Best Gift for Mom on Mother's Day - Solar Water Heater Made of Beer Bottles


Ma, a 42 years old farmer in China recently build a simply solar water heater from beer bottles as a gift to his mother. This heater only cost about twenty dollars and three days labor. Now this simply water heater is expanding within the village and more rural elderly people are benefiting from it. Ma's long goal is to promote this device into more rural areas in China.

    It would be truly useful if you could post a simple schematic or even just a closeup photo, showing a basic detail or two about the water heater's construction. How does water circulate between the bottles?
