Fill your PAC LOK hibachi with wood chunks and place on top of the Proto or Star Fire stove supports. With the right amount of heat and time you can produce your own charcoal. Prep your wood small enough to feed into the top port and front access door. Start with full load, hot fire. Feed prepped wood throughout the burn to maintain good heat and control. A batch of usable charcoal can be made off grid with this utility stove. You can also utilize a coffee can or even a dutch oven, set down inside your PACstove. The hibachi set up works better for smaller charcoal chunks. The coffee can works great and fast for high quality charcoal but may destroy the vessel after a number of uses. You have options.
For this set up, make use of common waste stream items like food cans and pie tins. Poke holes out of the base of one can and fill with pine sap. Cover this can with a larger can. Be sure that the inside can has the punched holes on the bottom. The stove drain hole in the bottom will receive and drip out the filtered pine sap. Use a common pie tin to collect your resin below the stove. Pine tar can be further processed in to medicinal salve's and balms. Used for fire starter, or distilled further into turpentine and pine rosin.
No firewood where you live? No problem. The paper jack is designed to be used with very commonly available items. See pics. Just through testing this device, we put several recycle containers out of business for the year. It will fit over the common 5 gallon bucket. You can make briquettes without wax or pine sap and they work fine. Our briquettes leave a hole in the middle that you can fill with anything from wax, pine sap, to old cooking grease. Briquettes burn long steady and with very little smoke. Great for urban environments.
With a minimal materials you can produce decent quantity of your own activated charcoal for water filtration. A simple coffee can with a metal lid and nail hole is enough. Use same method as pine tar rendering however we use a coffee can with stainless steel pet water dish for a cap. Fire wood is placed on and around the can as it sits in the bottom of the stove. Any addition of wood through out the burn should be done so as not to tip over your can. The pet stainless steel dish with tapered sides works well with a common coffee can although the coffee cans usually last through 4-5 burns only. One cycle at this quantity is more than enough filtration media for an average person. Procure your own sand and gravel layers from a river bar and use heat over your PAC stove to clean and pasteurize before adding to your filter. Your simplest and easiest form of a filter would be a common 2 liter bottle with the bottom cut off. You can decide to get fancier but that is base line and easy to find world wide. There are a couple other items needed to rinse your media but you can decide on your needs. Distilled water and lemon juice are the only other things you will need for the rinse step.
