Today, the access to electricity is considered as existential. Even small amounts of energy already mean a huge improvement of living conditions. Nevertheless, at the moment still two billion people worldwide have no access to modern energy services. Also in countries with public energy grids there are many situations without power supply: For instance in remote places, at mountain huts, while outdoor activities or most notably after natural disasters and crises. No matter where and why people have no access to electricity, there is one thing all this situations have in common: Under this circumstances people usually use fire — for cooking, for heating or to illuminate the darkness at least with a few candle flames. IGNIS is a tool that uses the heat of these flames, transforms it into electricity and stores it to provide light and power whenever and wherever needed. It can simply be placed on a hot stove while cooking or heating. In addition, at places without an oven, IGNIS also offers the possibility to produce heat by burning ordinary household liquids like spirits, any oil or even used frying fat that is available in every home.
