While high tech CFV (Capillary Force Vaporizer) burners represent an advance in technology they are unfortunately too high tech to be offered to DIY stove builders as a solution.
Fortunately a low tech CFV stove can overcome the limitations and disadvantages of both the high tech CFV stove and the alcohol fueled beverage can stove by using low temperature evaporation of alcohol fuel fed to the flame at the perimeter by an encompassing pad wick made of almost any absorbent material. In fact, it might (except for the flame) be mor properly called a Capillary Force Evaporator stove.
While being easy to construct and simple to use it can be made to meet virtually any fuel storage, thermal generation capacity or durability requirement in addition to making replenishment of fuel during operation possible and startup hassles a thing of the past.
A basic low tech DIY CFV stove can be built quickly in an emergency to meet most any fuel or thermal need but with more time and materials it can be adapted and built to accommodate virtually any backpacking, camping or other need.
Step 1: Gather the materials and tools
To construct the test stoves I used aluminum flashing, since it is about the minimum thickness that can be secured with 1/8" pop rivets. Brass, stainless or aluminum machine screws can be used in place of aluminum or stainless pop rivets. I used aluminum pop rivets since I will most likely not be taking the stove apart. In the event I do need to take it apart, aluminum rivets are the easiest to remove. You'll need a pop rivet gun if you go with pop rivets as well as 1/8" by 1/8" pop rivets plus the length of the thickness of the stove you want to build - usually 1/4" long rivets will allow adequate space for fuel. Be careful not to over compress them as I have done.
Next you'll need some aluminum door screen. The dimensions of both the aluminum sheet and the aluminum screen as well as the number of pieces is the same. You will dimensions big enough to cut circles about 1/16" to 1/8" greater than the pot you plan to boil water in. For a frying pan you will want dimensions that are half the diameter of the frying pan. I used kitchen shears to cut both the screen and sheet.
You will need a straight edge, ruler, scribing compass, a power drill and 1/8" bit and some absorbent material. I used regular kitchen paper towels but cotton or fiberglass cloth would certainly be more durability. The choice of absorbent material is yours with the exception of synthetics and plastics, which melt. Update: I've now tried fiberglass angle hair, mat and asbestos cloth and I'm not really happy with either. The hair is extremely absorbent and for that reason the fuel can not be added before the pot is placed on the stove else half will spill. The fibers of the mat are too straight and stiff and will come loose and break into splinters. I have tried to seal them on the edges and sides with a blow torch but the glass can break and expose the fibers again. Asbestos cloth is best so I imagine fiberglass cloth would work at least as well.
I recommend alcohol fuel only since oil, mineral spirits and kerosene need to be heated inside a closed vessel until they become pressurized or they will burn incompletely and produce excessive carbon monoxide and soot.
