DIY Survival Heater/Stove! New/Improved!! (it's a Heater and a Stove!) non-electric! alcohol powered

DIY Survival Heater/Stove! Two "Metal Can" Air Heater and Stove Combos! 2 new designs, how to make them (with full instructions on using them) included in the video. this is an upgrade or improvement to the standard "toilet paper in a metal can" air heater. these upgraded versions work as air heaters and stove burners and are insulated, have greater stability and have thermal mass. i built 2 models with 2 wick sizes. the cooking and heating power of each is shown in the video. the flames on these are powerful so cast iron pots and pans work the best for cooking. regular metal pans are the best (the fastest) for boiling water. as for heating; one unit can heat a big area. i had two going and the whole front half of my house heated up (40F [4.44C) outside at the time). i used both 70% and 91% isopropyl alcohol as fuel. both work well. to convert the unit into a stove just coil up a small piece of 1/2" hardware cloth. (4 squares high) and set it on the gravel (or dirt) surrounding the inner can. works great! great for any off-grid situation (emergency, power outage, camping) or just for general everyday use. be prepared. make it "before the storm". remember to aways use caution around open flame. one easy way to put it out is to cover it with a metal spatula or the bottom of a metal pan. tip: the "wick" lasts a long time (but eventually needs to be replaced). when it's time - you can get an extra use (double-use) out of it by just flipping it over, and reinserting. note that dirt can be used in place of the gravel if gravel is not available. coffee can model is made with a #10 (coffee can) style can and a 28 to 30 oz. steel food can (the inner can). wick on that one is a double roll. paint can model is made with a new empty (gallon size) metal paint can and a progresso soup can (inner can). wick on it is a regular size roll. if you like the vid. please rate comment sub and share.
UPDATE (1/11/2022): i just posted a video on how to add "flame size" control to these units! super easy to do! takes about 2 minutes. allows you to reduce the flame down to the size of a regular candle (or anywhere in between). here's the link to the video on how to do it    • The BIG CANDLE! Large DIY "Alcohol" C...
