There is an urgent progression of climate change due to air pollution caused by harmful substances produced from the use of fossil fuels and the increase in carbon dioxide. With the depletion of fossil fuels, interest in alternative energy that can replace fossil fuels is growing. Based on the technology of burning waste cooking oil, we have designed a heating device that can replace fossil energy and reduce the cost burden of fuel. It's a heater that can be easily used outdoors and has high firepower, making it versatile in various applications.
