Hello! I am new here, my name is Russell. How I prepare myself for hiking can be summed up as inventive scavenger. I try not to spend much money, instead I use what's abundant, and for some reason I have to much wax.
While hiking I find myself wanting more and more to start tea or hot water for oats as I wake up, and be ready before I get to packing up my shelter. I find tea lights work great for a couple runs of warmish water and are free because i refill with bees wax and replace the wicks, but they just dont have the speed I am looking for.

I am obsessed with rocket stoves but after watching my friend operate his portable Gasification stove and reading on here about someone's encouragement to create one with a candle, I got an wild idea. So two hours later I jury rigged up the only beer can I could find into a two chambered, self feeding, gasification, candle stove.

I took it for a run, took 11 minutes to get a decent boil. I originally had a rubberband lifting up the candle as it melted, but after 6 minutes it burnt up and dropped the wax, I was thinking of finding a small spring to replace it, the gassification didnt work until the candle dropped, it was still sputtery, so larger holes are needed (i used a thumb tack for vents). That aside, the idea of it is the outer shell and the candle tube are compression at the top while I insert a metal wire through both of them, one to hold it secure and two to prevent the candle from continuing to rise from the rubber band's tension. the bottom cup is to catch drippings and compress the candle tube secure from the bottom, also can be used as snuffer.

Let me know if this is to far fetched, I appreciate all feedback.Candle Gasification Stove

Another idea

Take an egg carton. Break into individual egg sections. Wrap outside in aluminum foil. Put 1 ounce of wax into each section. Turn on oven to lowest setting. Put sections in oven. Wax should melt and saturate the egg carton. Let cool. Remove aluminum.

This has a good amount of "wick". Put one of those in your stove. You won't have to adjust the height. Play with it and see if 1 ounce is the right amount to boil your water. I've played with this a little, but mostly I just use for fire starter.

Wax has about as good heat for the weight as anything else. Alcohol, as an example, is twice as heavy for the same heat. Wax, butane, white gas are all about the same.

Or google Dave Thomas posts – he had a bunch of ideas – you've probably already done that

Jerry,

"This has a good amount of "wick"."

Could you elaborate? Are you using the egg carton as the ignition point and wick?

You take a section of egg carton. One egg's worth. Put 1/2 ounce of wax in it. Put in oven so the wax melts and saturates the cardboard of the egg carton. Some wax at bottom of section.

The "wick" is the cardboard that goes around one egg:

egg carton

I leave one corner long, and then tear it off to light it. The fibers are easier to light. Otherwise, it's hard to get it lit.

The wick of a regular candle is way too small – not enough flame – takes forever to heat up water – it will only get warm, not boiling

The old "boy scout" method of coiling up cardboard in a tuna fish can is an idea, but way too much wick, and way too much wax. Hard to put out flame.

1/2 ounce of wax in one section of egg carton is the right amount to boil a pint of water. Or maybe it's 1 ounce. I just use this as a fire starter and have only boiled water a time or two.

There's a good BPL article about candle stoves. I believe they used a "plus sign" shaped wick of cardboard on edge in a container of wax. More or less wick didn't work as well. But then you have a big container of wax that's hard to put out.
