Although I'm not an expert in this field, I have an idea for a arc lighter that can be charged by simply walking with it in your pocket. With an hour of walking, it should be possible to generate enough power to light between 5 to 10 cigarettes. To enhance its functionality, I suggest integrating a solar cell which can charge the lighter when exposed to sunlight, so you can load it at balcony when you are home. Additionally, in case battery depletion, it would be possible to add a foldable crank to provide a manual backup power source.
