The Solar Spark Lighter is the world’s first pocket-sized solar-powered fire starter. It’s an ideal tool to carry along when you go camping. However, this one doesn’t have an induction coil that requires electricity, and neither does it convert light into electricity using photovoltaic cells. It’s just a small stainless steel parabolic mirror that reflects and focuses the sun’s heat to a single focal point in the center of the mirror. If you’ve burnt holes in paper or leaves using a magnifying glass, then you know how this works. The heating element at the center captures all the heat, so you just need to touch a cigarette or paper to the element to make it go up in flames. Even so, it’s best to keep your kids away from it to prevent accidents.
