So for purposes of clarification,

My Wheelbarrow Thread

really should have been Corona Timekiller 1, which would would then make

Corona Timekiller: Hanging Ramps in my Garage

   Corona Timekiller 2

And so now I present Corona Timekiller 3: Making a $100 Cup of Tea with a Rocket Stove.

I learned about Rocket Stoves a few years ago (maybe here) and I have wanted one ever since. This kind of seemed like a good time to pull the trigger on one, so after a little comparison shopping, I placed an order on eBay.

About a week later, and following some very good communication with the seller, a very nicely made, and well packaged rocket stove arrived at my doorstep.

They are designed to burn just about any kind of combustible waste that you can scrape together. So I gathered up some assorted sticks and slightly larger scraps of wood from around The Estate.

 

Getting it to light took a little more effort than I had expected, but I don't think that my wood was very dry. With some judicious selection of super dry dead sticks, a little cardboard and a few breaths of supplemental air, it cranked right up. I also put a couple of pieces of wood in the vertical chimney to get the draft moving in the right direction.

My goal for the day was to boil water and make tea. I was a little overly optimistic at the volume of water that it could boil quickly at first, but after dumping a little off, we achieved a rolling boil in a relatively short period of time, thereby proving the concept.

Once this thing is up and running, it will burn just about anything. Small dry sticks are easiest, but I also supplemented it with half a handful of wood pellets at one point. I even burned the wet tea bag when I was done, and there was no sign of it during cleanup. The key is to avoid building up a lot of ash at the bottom, which would restrict the flow of fresh air to the fire.

Combustion is very efficient. I am sure that I could improve heating efficiency by stacking blocks around the vertical chimney to minimize heat loss and keep it all aimed at the cooking surface.

I am happy with my purchase, and I am confident that I can boil water, heat a can of soup, or even cook a steak on a skillet with this thing.

And...it's kind of fun. Two Thumbs Up!

I will send you to coordinates of the island that I will be seeking refuge at once mended. Bring that with you.

I've been doing that in my head for about three years, but I finally decided to just spend $100 and have one mailed to me.

Firefighter unable to start fire, cites years of doing the opposite. News at eleven.

 

That's a nifty little device. I'd love to know how hot you can get it going- it might be decent for melting lead outside.

Airflow was a little better when I threw a scrap metal cover over the feed port. Some stoves come with a similar hinged cover.

So, for the dummies of the group (namely me) is this just a way to get a screaming hot stove? Does it have a specific purpose?

I'm thinking a stainless J bend in 3" would do the job with a slight mod to the J. Tack a couple flats to the bottom and we are in action.

You can cook stuff using very little fuel. Sticks and twigs.

It sounds like you’re in business. Or at the very least, you can build a really big rocket stove.

When I was a kid I used to use the British army method of making hot drinks which was to fill a tuna can with sand and pour some lighter fuel over it. It will burn long enough to boil water or a can of soup.

Try running  birch bark in it. It ought to run extremely hot. Birch bark also has the very handy property  of lighting with a match while soaking wet.  At my cabin kerosene is called liquid birch bark

A fireman fascinated by fire. Who'd have thunk it. laugh

I keep threatening to build one, but I have so much crap now it's not even funny. When the world ends I'm just going to have to get by with a regular fire.
