Ma Yanjun, a farmer in the Shanxi province of China, wanted to find a low-tech, low-cost way to heat water for his mother’s showers. 66 beer bottles attached to a board on the roof of his home turned out to be enough to provide hot water for all three members of his family every day. The bottles are connected, and sunlight heats the water as it slowly passes through them before flowing into the bathroom.

16-year-old Peter Ash of Somerset, England invented a hamster-powered cell phone charger for a school science project. For this incredibly innovative DIY project, Ash attached a generator to his hamster’s wheel and connected it to his phone charger. “I thought the wheel could be made to do something useful so I connected a system of gears and a turbine,” he said. “Every two minutes Elvis spends on his wheel gives me about thirty minutes talk time on my phone.” For all that effort – and the recognition he’s gotten on the internet – Ash received a C for the project.

This tutorial also uses scrap carpet from a dumpster, old plastic shopping bags and some glue. They may not win any fashion accolades, but they’re non-slip, eco-friendly and practically free.
