Quick Answer
Reflective space blankets can be used to start a fire during storms by reflecting sunlight onto a focal point, generating heat and potentially igniting tinder. This technique requires a clear patch of sky and precise aiming. It is a viable option when other fire starting methods are not feasible.
Using Reflective Space Blankets for Fire Starting
Reflective space blankets, also known as emergency blankets, are designed to retain body heat in cold environments. However, they can also be used to start a fire by reflecting sunlight onto a focal point. This technique is often referred to as a “solar fire starter.”
Preparing the Blanket
To use a reflective space blanket for fire starting, first ensure that you have a clear patch of sky and a dry, flat surface to work on. Next, locate the center of the blanket and mark it with a small rock or stick. This will serve as your aiming point. The reflective surface of the blanket should be facing upwards, towards the sun.
Focusing the Sun’s Energy
To focus the sun’s energy onto a small area, you will need to adjust the blanket’s angle and position. The goal is to create a concentrated beam of sunlight that will heat up a small area, eventually igniting tinder. A general rule of thumb is to aim for an angle of around 30-40 degrees, with the blanket’s center aligned with the sun’s rays. You can use a small stick or rock to help adjust the blanket’s position and angle. As you adjust the blanket, observe the spot where the sun’s rays are landing. This will give you an indication of where to place your tinder.
