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.

The bottles are connected, and sunlight heats the water as it slowly passes through them before flowing into the bathroom.

It folds up into surprisingly convenient little pockets, and a little Velcro makes the perfect closure.
