What You'll Learn
Convenience and cost-effectiveness of propane vs liquid fuel
The convenience of propane versus liquid fuel is largely dependent on context. For instance, propane is a popular choice for automotive fuel, as it can be produced and distributed domestically, reducing reliance on imported petroleum. This also makes propane a more convenient option for high-mileage vehicles, as it has a high octane rating, low carbon emissions, and low oil-contamination characteristics, improving engine life and reducing maintenance costs.
Propane is also a convenient option for outdoor fire pits, as it does not require certified gas installation or a gas line to operate. Additionally, propane is considered a "green fuel" and is environmentally friendly, contributing to improved public health and a resilient transportation system.
On the other hand, liquid fuel, such as gasoline, may be more convenient in certain situations. For example, gasoline has a better average fuel economy than propane, and in the context of heating a home, natural gas (a type of liquid fuel) may be more cost-effective if the price is low enough (generally under $20 per 1,000 cubic feet).
In terms of cost-effectiveness, propane is generally considered more cost-effective than liquid fuel options, especially when taking into account the environmental benefits. Propane has lower operating costs due to its typically lower cost per gallon, and it is more energy-efficient, delivering more BTUs (British Thermal Units) per gallon or per cubic foot.
However, there are certain contexts where liquid fuel may be more cost-effective. For instance, in the case of constructing a permanent fire pit, installing a natural gas line may be more economical in the long run, as it provides an unlimited supply of fuel without the need for refills.
Overall, while there may be specific situations where liquid fuel is more convenient or cost-effective, propane generally offers greater convenience and cost-effectiveness, especially when considering its domestic production, reduced environmental impact, and improved engine performance.

The risk of water in the fuel tank
Lanterns, particularly those used for outdoor activities like camping or hiking, often feature a double fuel tank design. One of the primary reasons for this is to separate fuel from water, which is crucial for several reasons.
The presence of water in the fuel tank can pose several risks and negatively impact the performance and safety of the lantern. Water can enter the fuel tank in several ways; it can condense and collect inside the tank due to temperature changes, or it can accidentally mix with the fuel during the refilling process if the lantern is used near a water source for an extended period. Having a double fuel tank mitigates these risks by providing a built-in mechanism to separate and trap water, ensuring that it doesn't end up in the lantern's burner.
Water in the fuel can lead to corrosion and damage to the lantern's internal components, especially if the lantern is not used for extended periods between uses, as water can react with the metal parts, causing them to rust or degrade. This can result in reduced performance, blockages, and even permanent damage to the lantern, rendering it unusable.
Additionally, water can negatively impact the combustion process. When water mixes with the fuel, it can affect the vaporization of the fuel, leading to an inconsistent or incomplete burn. This not only reduces the lantern's light output and performance but also results in the release of unburned fuel, which is both wasteful and potentially harmful, as it can produce noxious fumes.
The separation of water from the fuel is, therefore, a critical safety feature. By preventing water from reaching the burner, double fuel tank designs reduce the risk of unexpected flameouts or, worse, fuel leaking out of the lantern, which could create a hazardous situation. This design ensures that even if water does enter the fuel tank, it can be safely separated and drained without affecting the lantern's performance or compromising safety.
In summary, the double fuel tank design in lanterns is a practical solution to manage and separate water from fuel, ensuring optimal performance, longevity, and safety. It is a simple yet effective mechanism that allows outdoor enthusiasts to rely on their lighting equipment even in challenging environmental conditions.

The brightness of the lantern
The brightness of a lantern is a key consideration when choosing a lantern for camping or any other outdoor activity. The Coleman Powerhouse Dual Fuel Lantern is a popular option that provides a bright, steady glow of up to 800 lumens with a range of up to 22 meters. It offers an adjustable control knob, allowing users to tailor the brightness to their needs, from a subdued glow for a festival to maximum brightness for sports events.
The Coleman lantern's brightness is also influenced by its fuel type, with users reporting that it performs better and provides a longer run time with Coleman fuel compared to unleaded gasoline. This lantern is also self-cleaning, ensuring that the brightness is not affected by a dirty burner.
For those seeking even brighter options, the Northstar single-tube double-tie propane lantern is a good choice. It is reported to be significantly brighter than the white gas powerhouse lantern, but it is worth noting that at full brightness, the hissing of propane can be loud.
Liquid-fuel lanterns, such as those that use kerosene or white gas, may require re-pressurization during their runtime, which can impact their brightness. Propane lanterns, on the other hand, maintain a more consistent brightness due to pressure regulators.
Overall, the brightness of a lantern is influenced by its design, fuel type, and maintenance, and it is important to consider these factors when selecting a lantern for activities that require specific lighting needs.

The safety of the lantern
The safety of a lantern is a critical consideration, especially when using flammable fuels. Lanterns have evolved over the centuries, from early candle-powered and animal oil-based designs to the modern-day liquid-fuel and propane lanterns.
The safety of a lantern is closely tied to the type of fuel it uses and the lantern's design. For example, early whale-oil lanterns were designed to transmit more heat into the fuel, requiring a much higher flashpoint. Using the wrong fuel with a low flashpoint could result in a runaway flame or an explosion. Kerosene, for instance, has a minimum recommended flashpoint of 124 degrees Fahrenheit for safe use in oil lamps and lanterns.
Some fuels, like gasoline, Coleman Fuel, white gas, and paint thinner, are highly dangerous and should not be used in lanterns due to their low flashpoints. If the fuel's flashpoint is too low, the fuel in the tank can heat up, create vapors, and ignite, causing an explosion or a blowtorch effect. This risk is mitigated by using the correct fuel and ensuring the lantern's design keeps the fuel tank away from heat and ignition sources.
Modern lanterns, like the Coleman Dual Fuel Lantern, offer dual-fuel technology, allowing users to choose between Coleman Liquid Fuel and unleaded gasoline. This design provides convenience and economic advantages. However, users must still be cautious and follow proper procedures to maintain safety. For example, ensuring the lantern is pumped up to maintain sufficient pressure and brightness.
Additionally, the use of mantles, small woven fabric bags that attach to the burners, is essential for safety. They help produce illumination while keeping the fuel tank away from direct heat. Spare mantles are recommended as part of a camper's standard supplies to ensure safe and continuous use of the lantern.
