Using denatured alcohol, 1 fluid ounce boils 16 ounces of water
The Caldera Cone is a cleverly designed alcohol stove system. It is lightweight, compact, and eco-friendly, making it ideal for backpacking and camping. The stove's base configuration includes an alcohol stove, a fuel bottle, a measuring cup, and a combination pot holder/windscreen (The Cone). The Cone is designed to fit specific pot sizes, optimising burn efficiency.
When using denatured alcohol with the Caldera Cone, 1 fluid ounce (approximately 28 ml) is typically sufficient to boil 16 ounces (4 cups or 1 pint) of water. This amount of fuel provides a rolling boil within 13 to 14 minutes. After boiling, there is often a small amount of fuel left over, which can be poured back into the fuel bottle for future use.
It is important to note that boil times and fuel efficiency can vary depending on several factors, including ambient temperature, altitude, wind conditions, and the starting temperature of the water. For example, in colder temperatures, methanol-based fuels like yellow HEET may be preferred due to their lower boiling point, while ethanol-based denatured alcohol may offer higher energy output in warmer conditions.
Additionally, the Caldera Cone's design allows for efficient heat retention, and its compact size makes it easy to pack and carry. The system's windproof feature further contributes to its fuel efficiency by minimising heat loss due to wind.
The Caldera Cone alcohol stove system is a popular choice among outdoor enthusiasts, offering a lightweight, quiet, and efficient solution for boiling water and cooking during camping and backpacking trips.
