In 2003 I posted the original instructions for a hiking stove that I had been developing for many years - one that is dependable, safe, lightweight, fast, efficient, but is still simple to make and use. I called it the Penny Stove. Making the Penny Stove Making the 1/2 Penny Stove Penny Wood Backpacking Stove |

Please not that these are controlled tests and different environments, pots,
lids, pot stands, and building techniques may increase boil times and/or fuel use.
Wikipedia gives these specs for "normal" beverage-can stoves:
* Time to boil 2 cups (500 ml): ~5 minutes (<2 tablespoons (30 ml) of fuel)
* Time to boil 4 cups (1 l): ~12 minutes (<3 tablespoons (45 ml) of fuel)
Compare these with tests of the Cat, Pepsi, and best commercial stoves at:

Thru-Hiker.com plotted the daily weight of stove+fuel for five stoves boiling two cups per day for a 14 day trip.
I have added the Penny to their chart showing how it relates to other stove and fuel options.
The Penny average is 5.25 oz/day, the Esbit is 5.1, Canister 7.8, Cat 7.4, Wisperlite 20, Doublewall 9.4.
What about the super high efficiency Jetboil Personal Cooking System stove?
Below the Penny & grease pot is compared with Jetboil & integrated pot as tested by backcountry.com
- based on a 14 day trip boiling 2 cups per day.
The Penny average is 8.5 oz. per day, Jetboil is 17 oz. per day.
First day Weight -14 day trip
Jetboil = 18 oz (pot & stove 14, fuel 4)
Penny = 12 oz. (pot & stove 5, fuel 7)
~Last day Weight -14 day trip
Jetboil = 16 oz. (pot & stove 14, fuel 2)
Penny = 5 oz. (pot & stove 5, fuel 0)

"Penny...wow! |
..."Just back from a very cold 4 days hiking north Shenandoah, snowed last day. First day with a wind chill factor of -9 degrees, temp was 14 degrees. Made and used for the first time a "penny stove" for the trip. Performed like a champ!!! Not affected by wind, or cold. Boiled water in minutes, simmers forever. Never have used alcohol stove before..... I would recommend this stove to anyone, anywhere." asphalt commando ~ |
"I shit you not...I put this thing together starting with two empty cans (did not bother yet making the lid) in less than 30min. Couldn't wait to test it following such an easy assembly. It brought a camp pot with 32oz of cold water to rolling boil in 7 minutes (920' elevation) and had fuel to spare for the simmer with the ring on. You've created a marvelous little jewel here man. I am very impressed!! I am taking this thing to elevation in the Rockies next summer to give it the major field test. I am sure I will not be disappointed. Kudos!! " Brian Parks, Madison, WI ~ |
"Having constructed and tested nearly every homemade version as described on the alcoholstoves website I was pretty impressed with Mark's claims for his penny regulator version using the Heineken beer cans. Soo...I had to make a couple just to check it out. The results of my comparison tests were pretty amazing! The penny stove burned much more consistently without flameups, it did not need a special primer ring to preheat the fuel, and it actually brought 2C tap water (71F) to boil in 3.5 minutes!!! Starting with 1 oz fuel, I had another 3 minutes of burn time after achieving the boil. ... I timed the boil to where it actually lifted the lid, not to where steam was observed. Also consider that I live in Aurora CO where the elevation is in excess of 5000 ft, therefore the boiling point is somewhat lower... Guess what I did with all my other stove versions! (deep 6)" Lin McEnerny ~ |
"I made a stove based on your instructions and it was the only source of heating water that I took on a 8 day 7 night hike through the Olympic National Park in Washington State. It worked faster than the white gas stove the other two in my group shared. The weather was cold and wet, but the stove worked flawlessly. Of all the designs out there, the penny alcohol stove is easiest to make, pack and refuel. Best of all, I made it myself and everyone I camp with has been amazed and impressed. The penny weighs as much as the stove. My views are my own and may not reflect the views of my employer, wife, or my dog. But I do strive to keep all of them happy." Russ Whitt ~ |
"I built the penny stove last summer and used it on a 2.5 month camping trip in Europe. It worked every time, 100% of the time, rain or shine. I had to write and say thank you for coming up with this elegant design. It is the perfect stove, especially for international use. If it gets confiscated at security, it takes about 30 minutes to make a new one. Fuel can always be found, even 70% isopropanol at drug stores if necessary. Simmers perfectly. Thanks again! Paul Lapides ~ |
... we are farmers in North Sulawesi, want to produce Bioethanol from Arenga Juice (Arenga Pinnata trees, palm family). Therefore we need alcohol stove, which, safe, cheap, eficient, durable, easy to make and has long burning time. After searching an learniing the nets for months, we decided to take your penny stove for our stove. We will sell the stove for household user, its price range usd 0.4-0.6/pcs. The stove will be sold to over 20.000 household in North Sulawesi. We will introduce Bioethanol as alternative fuel because North Sulawesi has over 2 mio Arenga trees and price for kerosene fuel will be higher and higher. Nocke Sumampouw, Manado-North Sulawesi Indonesia ~ |
"My wife and I have been backpacking for approx. 1 year now and as most, we have gotten addicted and into lighter and better. We bought a Snow Peak GigaPower stove and a Vargo Triad titanium alcohol stove. As part of my research into lighter gear, I stumbled across your design and decided to give it a try with both soda cans and the Heiny cans. The Heiny, in my opinion, is far superior (more durable). |
"I have actually made a penny stove with my leatherman... |
"I hiked the entire Appalachian Trail last summer using two penny-alcohol stoves. The only reason I used two is because I had a bad boil-over once and gummed up my first one. Due to the light-weight, the small size, the fast boil, and the geek factor, the penny alcohol stove is definitely the best and coolest camping stove ever. Thanks!" Fred the Red ~ |
"The Penny goes a step further and corrects a problem common to alcohol stoves. When alcohol is vaporized too quickly, it escapes through the jets without boiling, lowering fuel efficiency. The Penny uses a novel design to counteract this - a penny covers the fuelling hole and seals the stove until boiling alcohol accumulates excessively. At that point the penny lifts due to the pressure and the gas is released slowly and burnt off, preventing fuel loss. The stove took me a couple hours to make and is constructed of a couple ridged Heineken cans. I took this stove on my 5 day hike through Northern Japan, and also cooked with it for 3 other days spent at campsites in towns. What a rocket! I started my trip concerned about fuel consumption because I had to boil all of my water to kill a waterborne parasite that is rare but possible in those mountains. The Penny boiled tons of water, and in about half the time -- 4 to 5 minutes -- of other alcohol stoves. ... In any case, highly recommended: it weighs 19g and boils nearly as fast as clunky gas stoves." wendingwayfare.com ~ |
"Thanks for coming up with this stove. I think it works really well... I found that by using an 8 oz. Pepsi can as the burner you don't need to crimp it. It slides right in. I just got done with a simmer test and found by using the original simmer ring I was able to simmer hot water for over 56 minutes. I used 1.25 oz. of denatured alcohol. Thanks again," Phil Perkins ~ |
"... I must say, your penny valve is beyond clever; it is absolutely ingenious! I am amazed everytime I see the hot alcohol draining down beneath the penny. I have no idea how you figured that out. How does it work anyway? Is it because the surface tension drops once the alcohol gets hot?, or is it because of the heat expansion difference in metals? or is there some kind of divine intervention involved? LOL It is absolutely incredible invention! Incidently, I tested nickels and dimes as well, and your penny valve works best. Thank you! Don Trapp ~ |
"We had a blackout today and I made your stove from Heineken cans. I was able to cook eggs, french toast, & boil water for our coffee press. Needless to say, it has made the day so far quite tolerable... |
"Your design is elegant indeed! I just used it on two camping/ backpacking trips in Death Valley, CA and the mountains of Pennsylvania. It's performance was excellent, even with 50 mph wind gusts (with windscreen of course)." Bob McLaren ~ |
"For cooking, I cannot more highly recommend a Penny Stove... I had friends over last night, and we got on the subject of preps. They were "unbelievers" in prepping. I broke out my penny stove and camp pot. Cooked up 2 cups of rice in 20 minutes with 2 tablespoons of Heet (yellow bottle) for fuel..." Mike S. ~ |
"... I think my wife is a little concerned about my sanity, but the design is so fascinating, I can't help myself. I showed your system to a friend of mine, a 28 year backpacking veteran, and he just about fell out of his chair when he saw the water boil. I had gone to his house to give him my now unused MSR Whisperlite, which he immediately stuck in a corner of his garage in favor of building a penny in my shop next time we get together." Jeff Mauerman ~ |

"You are certainly welcome to use the photo on your website. It would be rather an honor, considering that your stove design is by far the best I've found online. I've made close to ten of the stoves, given most away, and used them from southern Mexico to Washington state. Thank you for releasing the design on the 'net!" Forbes Conrad ~ |
"The Penny Stove exceeds
my expectations! |
"When I read the part about using the popular "penny stove" I had to chime in. I found the instructions for building the penny stove on the internet back around Christmas time and decided to build one. The instructions were very clear and the cutting and assembly was quite easy. I've since taken the penny stove on 2 camping trips and simply love the stove. I've since built a couple more for my daughters and friends. There are 7 of us going on a 5 day trip to the Grand Canyon and 4 of us are sharing 2 of the penny stoves. Susan - I don't know if you've had a chance to use the simmer ring, but it works great too! It's pretty cool building something that actually works!" kl7rs, Sun May 8, 2005 4:14 pm, Ultralight Backpacking] Digest Number 379 ~ |
"I too used to like the beverage can stove, but have become a penny stove convert. It's more effecient and actually easier to build... I think it is a superior solution... I've made all sorts of alky stoves, and like the penny stove best for my purposes... |
"Hello, I have enjoyed making and using this design of stove. Heineken is definitely best, the premium cans (for burner) are a little different but epoxy glue works fine... Brilliant, as little as 10ml (we are quasi decimal here in UK!) will boil a 300ml mug. My wife thinks I’ve gone nuts staying late out in the garage! But I explain to her you can see the flames…… Ha! No Pacific Crest trail here, just the mountains (hills) of Snowdonia." Thanks, Chris Harper, Capel Curig, North Wales ~ |
"Your Penny Stove has been my favorite of all the stoves I've made, and I was thrilled to be able to use it out on the trail last summer. It really burned well! By the way, I pulled out the alcohol stove this week to teach my boyfriend how to use it on his trip in the Ventana this weekend, and I just never fail to be amazed by that design. It is really a thing of beauty!!! (and one that I was able to make myself, which is in some ways even more amazing!)" Debbie Kramer ~ |
"While skeptical at first, I love it. It's the easiest and most forgiving to build (but unfortunately requires Heineken instead of beer) and works better than the pepsi can design. I'm experimenting with the homemade alcohol stove genre and am happy to be impressed with your work. Thank you for your efforts. ...like most men I enjoy playing with fire. Guess not much has changed in 60,000 years of evolution." Chuck Bodner ~ |
"I have tried many different types of stoves over the years since I have been backpacking and camping. I have tried just about any type of stove I can think of. My preferred stove is the alcohol stove I made out of Heineken beer cans. It is called a Penny Stove. I have made several other types of stoves from soda cans and have not been as satisfied as I am with the Penny Stove. The Penny Stove can actually be used as a multi-fuel stove by flipping it over, putting a piece of screen in the bottom and using an esbit, or fire starter. The stove is very efficient and can easily bring 3 cups of water to a boil fairly quickly. It doesn't require a primer bowl to light it, and is extremely light weight. Can stoves are the lightest weight stoves I have seen. They are much lighter weight than the majority of commercial stoves on the market today. Though I mostly do boil-in-bag meals, I have tested the simmer ring for the Penny Stove. My impression was that it does exactly as the creator of the stove claims. It takes much longer to burn the same amount of fuel with the simmer ring than without. I was able to easily cook a pot of rice. This was regular rice that takes 20 minutes to cook; not minute rice...." Scott, hammockcamping.blogspot.com ~ |
"I believe there was a noticeable spike in the consumption of Heineken beer the week Mark Jurey announced his penny stove to the lightweight backpacking community. :^) The directions for making the stove are very clear and well done." Don Ladigin, BackpackingLight@yahoogroups.com ~ |
"While your stove and backward garden designs might appear "simple", "elegant" seems much more appropriate. The designs only look simple initially; in reality they embody complex design ideas boiled down to simple implementations." Mark Warren ~ |
"I really like your
stove design. It heats fast like the pressurized white gas stove,
is reasonably efficient like the best of the open alcohol designs and
best of all, it looks "cool" with the way the jets shoot the
flames out -- like the Viking gas cooktop in my wife's kitchen!" Cutman ~ |
"First,
I'd like to add my complements on Mark J.'s stove: A beautiful, simple,
elegant design. Great job, and thanks for sharing with this list!" |
|
"I have be able
to generate a burn time of 8 minutes with 30 ml fuel. Temperature change
of 157 degrees, effenciecy about 60%... The stove gives this result
with one of faster burn times, and offers one of the easist consturctions
available (Only Altoids/perlite stoves and fuzzy's stove are easier).
I am impressed with the stoves overall qualities, easy of constrution
and use. I suspect that effeicency of stoves is increased with approppiate
windscreens to help retain heat... Nice job on this stove. I will use
it." Mark Redlin ~ |
"I have finally cracked the nut on an alcohol stove that I actually like! The penny stove has consistently boiled 24 oz of water on 1 oz of fuel with lots of left over burn using an MSR titan kettle. I have found the 16 oz constraint that most stoves seem to have frustrating to say the least... considering that I'm a bit of a tea addict morning and evening. |
"1.5 oz Penny Alcohol Stove — MSR, Brunton, Jetboil cower in fear (sort of) |
"My favorite homemade stoves because the are easy to make and effective are the Penny Alcohol Stove and the Cat Stove." |
"This plan is human ingenuity
at its very finest. For the cost of a few beers (plus one penny), you
can build yourself a camping stove like no other. It's fuel efficient,
takes up little space in your backpack, and is about as safe as such an
item can be. The author's site has a decent tutorial on how to build this
Penny Stove and lots of scientific data to back up the claim that it's
the best travel stove for any money. If you've got the time, they've got
the plans." Jules Allen in the St. Ptersburg Times ~ |
"I recently had
the opportunity to enjoy your wonderful Penny Alcohol Stove site. I
built the stove, and it works exactly as described. I have never had
an alcohol stove- until recently I had a Seva 123 (how I miss that stove!)
but I was thrilled with how well your design works." R. Mark Adams, Ph.D. ~ |
"I use a chimney type charcoal briquette starter for my grill, the one with the newspaper and hassle. I was wondering one day about a better way to light the chimney and saw one of my little stoves and flash! Instead of using paper I use 3 ml denatured alcohol and place the chimney over the stove and there ya go. I have been using the Svea 123 since they were 20 dollars and now I don’t. Guy Clarke ~ |
"... I am very impressed, as it worked perfectly. It boiled close to a liter of water in about 6 minutes. As a comparison, I boiled the same amount on an electric range and got a boil at 6 minutes and 30 seconds..! I just returned from a backpacking trip in a Colorado wilderness area. Since my old trusty Svea 123 had come up missing, I bought an Optimus Nova for this trip. What a disappointment, as it took me about 20 attempts in 45 minutes to get it to light off at about 11,000 ft. elevation. If I had not been in such a dire need for my morning coffee, I would have smashed the damn thing to pieces..." Bill Pryor, Katy, Texas ~ |
"Just e-mailing to let you know that: 1. Methylated Spirits is denatured alcohol, 2. I tried the stove, and, 3. It's amazing. The concept, the quality, the heat, the boil times. To be honest, when I ordered it, it was for the novelty. I didn't think it would be good enough for the ground. But it is. More than good enough. From a military point of view, the cooker is faster and lighter than solid fuel, you can put it out at any time, and a bullet through a bottle of meths won't blow up a ruck like gas would. All it needed was a nice case to avoid it getting crushed, and voila, the best cooker I have yet used, and I've spent about 500 dollars on different cookers over the years. Thanks, again," Dónal ~ |
Scouting "...My fellow scoutmaster and I tinkered for many nights with the penny alcohol stove and wood stove and not only did we have a lot of fun working on the project, but developed some skills we could share with the youth on our troop. I made some modifications to the wood stove and incorporated the use of the penny stove into it as well, then field tested the units at elevations from 7,000 to 14,000+ feet. The penny alcohol stove performed spectacularly on Mt. Whitney, but I tired to use the wood stove as much as possible to conserve the limited amount of fuel I had brought. As it turned out, the penny stove was so efficient that I had about 5 oz. remaining when we finished..." Mike Lancaster, Aka Mountainman Mike, ASM Troop 354, Clovis, CA ~ |
""The stove burns denatured ethyl alcohol, a fuel alcohol which can be purchased locally at Fred Meyer for less than $10 a gallon (it is NOT drinkable). The stove takes 50 milliliters of fuel to operate, which comes to 13 cents for each use of the stove. Grenfell did the math. |
"This is all about education. People veto what they do not understand. There are several such things in our troop that have been met with apprehension. Make a couple of penny stoves and bring them to a meeting for a demo. Show the cost difference between the penny stove and the huge Coleman stove. not only in the purchase price but in storage and maintenance as well.... |
"My Scouts all build the penny stoves. The work well and are extreamly light... It took me 20 minutes the first time and I can now make a stove on the fly with little more than a scout knife in 10 minutes. It is also a great way to recycle." Patrick Caswell, Scoutmaster Troop 13 ~ |
