stoves became popular on boats as an alternative to dangerous kerosene stoves. Although denatured alcohol, such as Sterno, is more expensive than other fuels, and puts out less heat, it is often preferred as a marine stove for safety reasons. Alcohol stoves have also become popular as camp stoves because alcohol is environmentally friendly to burn. A beverage-can stove is an example of a very lightweight alcohol stove for camping.
