Spinning Circles

           Nendo, a Japanese studio, designed a mobile battery that users can charge by rotating it. The stick-like battery, called Denqul, was made for use in disasters to ensure people have a reliable power source. The battery can be charged from a plug-in dock but can also be charged via the cranking mechanism. Nendo originally considered using solar panels to power the device. The stick can be pulled out and extended to twice its length. Denqul consists of a generator unit that uses magnets and coils of wire to convert “rotation power” into power. The difference in this crank and an ordinary hand-crank is that an ordinary hand-crank requires a lot of muscle strain. It is available in three different colors.

           I think we can all agree that a constant struggle we all have is our phone’s always have low batteries. Now, most of the time, we don’t really need to be on our phone and it takes useless time. But, during times of need, natural disasters, we need our phone to be charged or plugged in to a charger. I can speak for myself in saying that the times I need my phone the most, is usually when it has the lowest battery. The Denqul provides a sleek design which I like. The powerbank chargers are ugly and are a big rectangle. The Denqul also requires human interaction, it gives the user a sense of achievement for working to charge their phone battery. To me, this is architectural ingenuity. They have also taken a hot market item and improved it significantly.
