Which stove?

[Cadenza]

I have tried to buy a RUCAS stove without success. Nothing on ebay. No response to repeated emails. Where can I get one?

RUCAS-Stoves@hotmail.com
Try this email. I had a response from him within 20 minutes and the stove was in my hands three days later.

Those RUCAS stoves look like the stoves I make, except maybe 1 cm wider, and they used a paint stripping chemical. Make sure to paint the stove with a clear engine enamel if it isn't already.

The stoves I make have 24 holes on the sides of diameter 1/32" and cost $7 or $8.

Beer Bottle Stoves.....so many designs out there. Here is one you missed and the video shows something interesting:




The Cobalt was designed while I was very active here in the DIY forum. It was made in response to a challenge made by minibulldesign.

The stove is the "Cobalt" it's jets blossom in under 20 seconds. They are available on ebay being sold by my son for $7.50. They are a one piece stove and have the original protective ink coating.

The stove is also available at my online store:

Here are some problems I have with these demonstrations:

- There's no reason to use a stove in water. If the ground is wet, place the stove on an upside down can. All alcohol stoves will be less efficient when in contact with a heat conducting surface.
- You should hover your pot 3" (or a little more) above the stove while it primes, so you can cook while the stove is priming.
- These stoves are meant to have a pot on them (after they prime) because they're "pot pressurized stoves".

The point of that demonstration, i think, is not the wetness, but the conductive heat loss. The demonstration simulates cold ground. Placing the stove on a can will still suffer from the coldness of the ground, as will any bark, ir rock or whatever is available as it will be the same temp.

The pressurized stoves, whether pot pressure, penny pressure or whatevs look cool but are fuel wasters. The might get ya to a boil a few seconds faster but at a cost of fuel grams (the grams add up rather quick on a long hike). I have more time in the bush than I do alcohol. Everyone has their own favorite stove for whatever reasons they feel are most important. BYOS (Burn Your Own Stove) In the end its all fire.

[cabbagehead]

An upside down can creates an air pocket. When the stove is put on top, it is well insulated from the ground by that air pocket. Dry wood is also a good insulator, but you have to make sure that it's an isolated wood surface that won't start a dangerous fire if an accident occurs.

[russb]

First, even dry wood will be the same temp as the ambient temp, which is likely to be sub zero. Again, the point was not that it won't work. It was a comparison between the two stoves.

I have been using alcohol stoves for a number of years, have a box of many different designs. Each year I seem to get a chance to use one at a lower temperature than before. This past winter was -22*F. Yes that is a negative. I am sure it is Not a record by any means, but I do know what i am talking about.

[russb]

BTW, if you send me some data, I can run efficiency numbers for you. Efficiency defined as heat potential from fuel transferred to temperature change of water. Let me know if you want me to do a run.

He finally got in contact with me through email and I ordered one. We shall see . . .

Good deal! I think you'll like it.

The guy is a little unorthodox in his marketing strategy,....like he has no clue about it.
But for my money his stove rocks. I have a drawer full of alchy burners,....some expensive titanium ones, etc. and the RUCAS blows them away.
Personal opinion of course, but I think it's also the nicest looking one.

I have no connection with the maker and it's no sweat off my burners whether he sells them or not. Truth is, the Emberlit-UL is my favorite cook stove. But for alchy, it's hard to beat the RUCAS.

[cabbagehead]

I forgot to post the page where people have been giving me comments about the stoves I make.

I'll send you a free Cobalt stove to try. I think you'll agree that it's better than the RUCAS once you've tried it.

Send me a PM if you would like one.

After watching someone blow up a canister during a hike last spring, I'm kind of scared of them. A good alcohol stove is a little slower, but not nearly as destructive if it blows up.

All I was saying is that the stoves were compaired in conditions they should never be used in. The comparison is invalid.

I understood you. I acknowledge the conditions were not real-life, however I countered that the conditions simulated a specific outdoor condition while controlling for other variables. This is how laboratories conduct experiments to determine effects of single variables, they use simulations. Thus I disagreed that the comparison is invalid for the reason you stated.

Well,.....how can I resist a deal like that !?
PM sent.

But,...I'll tell you what,.....I don't ask for free stuff. When I recommend a product it means I paid for it with my own money and would do so again.
If it works better than the RUCAS I'll send you a check AND get on here and tell everybody about it.

I'm sending it out tomorrow and I said it was FREE. You didn't ask me for a stove. If you find that you don't like it, get on this thread and let eveyone know what you didn't like about.

It's important to point out that alcohol stoves can have problems in cold areas and are far from windproof. The alcohol needs to vaporize to light and if the cold or wind prevents you from getting to the fumes you will have a rough time.

In the ultra cold, use a wick based stove, like zelph's fancee feest or starlyte. I have used both in subzero temps with no problem whatsoever. Not all stoves are this easy to use in the ultracold. Wind, of course, if definitely an issue hence the use of a windscreen with all alcohol stoves.

Thanks Russ. Here is a couple of videos to show how the Super Stove lights in cold breezy conditions:





I'll see if I can find the video made up in MN a few years back using the StarLyte to thaw out a frozen car door latch.
