The most popular alcohol fuel based DIY backpacking and camping stoves utilize aluminum beverage cans to provide a laminar or pressurized vapor fed flame. However, they have limited fuel storage and thermal generating capacity, durability and adaptability. Most require an extraneous pot stand or holder and have additional construction, storage, startup and usage needs.
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
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.
