Details: The patented (#D701,721) Solo Stove Titan is the larger version of the original Solo Stove. It is a unique wood burning stove that incorporates a secondary combustion for a more efficient and cleaner burn. The bottom vents allow air to enter and flow up the bottom of the grate to feed the primary combustion, a top down smolder. In addition, air entering in from the bottom vents heats up within the inner wall and rises up and out the top firebox vents causing a secondary combustion at the top of the stove. The Solo Stove Titan actually cooks the smoke out of the wood and then burns the smoke not once, but twice! This technique makes for a cleaner burn which means less smoke and higher efficiency. Forget the Fuel: Our stoves cook your meals with nothing but the twigs you collect on your journey, eliminating the need for heavy, expensive, polluting petroleum gas. It s easy to light, fast to boil and clean to use. Gasify your Wood: A unique gasification and secondary combustion process lets our stoves achieve a highly efficient and more complete burn. This means you ll use fewer twigs to achieve a boil. It also means less smoke while cooking. Travel Lighter: The Solo Stove Titan only weighs 16.5 oz and eliminates the need to carry fuel canisters – a great way to lighten your load. It also nests inside most pots leaving you with more space in your pack. Stay Green: By using renewable resources for fuel instead of petroleum, you re reducing your carbon footprint. You ll also keep fuel canisters out of the landfill. Be Prepared: The Solo Stove is great for emergency situations.
