Ma Yanjun, a Chinese peasant and carpenter, of Qiqiao village, Shaanxi Province has made a solar water heater – using only beers bottles and hoses. How does it work? Well, The beer bottles lie on a board in rows and are all connected by hoses, which allow cold water to flow through them. As the bottles and board lie outside, the heat from the sun warms the water in the bottles. The warm water can then be used for showers, or meals, or most anything we use hot water for.

“I invented this for my mother. I wanted her to shower at any time more comfortably,” says Yanjun.

According to Pakistan’s Daily Times, since his invention, Ma has helped more than 20 families in the village to make and install their own beer bottle solar water-heaters. He told the paper he will build a public bathroom for the village using his invention when he has the money to buy enough beers.

Great to see some creative and “green” uses for all the beer bottles we tend to empty. Well done, Yanjun!
