This is the greatest DIY and eco-friendly project that I’ve ever seen. The Chinese farmer, Ma Yanjun, had found a great way to recycle all the beer bottles he had and turned all of them to form a solar-powered water heater for his mom. I guess noone had realized before that those old beer bottles could be so useful to make up a water heater that is powered by the Sun. Ma Yanjun used 66 beer bottles for his DIY project. All these 66 bottles are attached to a board and connected to each other so that water flows through them. Sunlight heats the water as it passes slowly through the bottles before flowing into the bathroom as hot water. Ma’s mom is simply the luckiest mom in the world as she’d received the greatest Mother’s day gift ever.
