Best Lightweight Alcohol Stove for Backpacking?

Looking for the most compact, simple, cheap, and lightweight alcohol stove on the market? Look no farther than Zelph Stoveworks' Starlyte Alcohol Stove. Here are the claimed specs from Zelph Stoveworks' website:

Weight: .6 oz
Dimensions: 2" x 2"
Boil Time: 6.5 minutes for 16oz water (1/2 oz of fuel)

Here's how it is supposed to work:

Measure out 1/2 oz of alcohol (HEET brand fuel line treatment).
Pour this into the base of the Starlyte Stove.
Light with a lighter.
Place the windscreen around the stove.
Set your pot on top to boil.
Have boiling water in 6.5 minutes.

all the various cooking gear in my set.

Why go with an ultralite alcohol stove?

They can weigh (in this case) 800% less than canister stoves. This is pretty considerable as far as weight savings go. No other piece of gear in your pack (probably) can be modified to get an 800% gain in weight savings.

Alcohol fuel can be carried in exact amounts. For example, if you're out for 3 days and know you'll need one fl oz of alcohol to boil your water per day, you can carry only 3 oz of alcohol. With a canister stove, you're stuck with whatever amount (and weight) of fuel that happens to be left in your canister.

Alcohol stoves don't have any moving parts (usually) and therefore are highly unlikely to malfunction in the field. The Starlyte stove has even less components than most alcohol stoves.

They're super cheap. You can make your own for free out of an old soda can. Or buy the Starlyte for $23. Opposed to lightweight canister stoves that will cost you $50-$100.

It's much easier to find alcohol fuel in many remote areas than it is to purchase canister fuel. This no longer holds true for the Appalachian Trail, however. There is now ample access to fuel canisters at various suppliers along the trail due to the high demand by hikers every year.

What it's like in the real world:


Alcohol stoves are generally much more vulnerable to physical damage than canister fuel stoves. If you accidentally step on, drop something on, or otherwise abuse your alcohol stove that weighs in at less than an ounce, you can expect it to not survive. Don't take this to mean that these stoves won't hold  a pot. Alcohol stoves are made to hold a heavy pot of boiling liquid, but they're not forgiving to damage.

Alcohol stoves must have a windscreen to use. These stoves don't burn with the intensity of compressed canister fuel. The flame is very vulnerable to wind gusts. Even in a perfectly calm environment, a windscreen is still necessary to conserve the heat energy of the stove. Alcohol stoves don't put out the BTU's that a canister stove can.

It's either on or off with an alcohol stove. There's no simmer setting. Once you light the flame, it's going to burn at the same intensity until it runs out of fuel.

Some alcohol stoves have the possibility to spill burning alcohol fuel everywhere if tipped over. The Starlyte stove avoids this by including a fiberglass-like material in the base to soak up the alcohol so that it cannot spill once on fire.

They can be very precarious to use. The Starlyte has a diameter somewhere around 2". Put a 6" diameter pot will of 16 oz of water on top of this tiny base and you've got a recipe for spilled pasta dinner if you're not on a very flat and stable surface.

What I've found with the Zelph Stoveworks' Starlyte Alcohol Stove:


Disclaimer: I've only done one test so far. Expect to see more results soon, as well as a video.

So is the Zelph Stoveworks' Starlyte Stove the best choice for going ultralight alcohol with your backpacking stove? Here's what I've got to say so far.

The let down:

I used 1oz of fuel (2x the suggested amount) to boil 16 oz (2 cups) of tap water. According to the manufacturer's specifications, 2 cups of water should boil in 6.5 minutes with only 1/2 oz of fuel. My findings?

With the windscreen securely in place, on a mildly breezy day (~8mph winds), my 1 oz of HEET denatured alcohol fuel burned for almost 11 minutes. In my Snowpeak Trek 900 titanium pot, 2 cups (16 oz) of water never reached a full boil. After about 8 minutes the water had developed fish-eyes (bubbles on the bottom of the pot) but by 10 minutes the water was still barely bubbling.

This was very disappointing as I used twice the suggest fuel and still never got a boil going in almost twice the time claimed by the manufacturer's specs.

Other lessons in alcohol stove use:

I also learned that (as stated earlier) it's very difficult to balance a pot full of water on a 2" diameter base. I can easily foresee spilled meals and boiling water in the future with the use of such a slim stove base. There's also nothing on the bottom of the Starlyte Stove to be able to grind into the soil to add stability (as the rim on the bottom of a fuel canister might be used to gain stability).

Furthermore, with my Trek 900 titanium pot, the handles had to be folded in to accommodate the wind screen. This leaves precious little to hold on to when opening the pot lid to stir contents, increasing the possibility of tipping your pot of boiling water over. The windscreen does its job well, blocking wind and holding heat in. Unfortunately all that heat gets channeled up to the pot handles and the pot lid, making it even more difficult to handle the stove while it's on the already unstable surface.

Conclusion:

At this point I've found out the hard way (as usual) some of the more subtle intricacies of using an alcohol stove. Considering the extremely cheap investment in a piece of gear that I've been curious about for some time, I do not regret the purchase. I plan to paint on some black grill paint to increase the efficiency of my pot and to conduct more controlled and numerous tests with the Zelph Stoveworks Starlyte Stove before giving a final "yes or no" answer as to how I feel about using this stove. For now, however, my canister stove will be staying in the backpack.

The Lightweight Backpacking Trend

The more time you spend reading about, writing about, and generally immersing yourself in outdoor culture, you will begin to see trends. I, for example, have noticed trends recently occurring in a couple of major directions. One major trend is a branch of running called Barefoot Running which I recently wrote about. Another trend is in the climbing world where Slacklining has taken fans by storm (it's fun, try it). The last trend I will mention here is Ultralight and Lightweight Backpacking which I will be discussing in some detail here.

In the last five years I have personally made a very rapid transition from hobbyist outdoor enthusiast to majoring in Outdoor Education, authoring a blog on outdoor activities, and testing all sorts of outdoor gear. As a poor college student I approach almost every situation weighing cost and benefit very closely. Something that seems to be a mystery to most outdoor consumers these days. My own perception of backpacking gear has been that a shift has taken place where people are more wrapped up in, and willing to invest in, new hyped up trends. Such as ultralight backpacking.

I've done some digging around and I think that you'll see these data trends reflecting some of my suspicions. Data for the following was taken from Backpackinglight.com's Press Kit, as well as Outdoor Foundation's Research Participation Topline.

According to Backpackinglight.com, "traditional backpackers" spend much less money on gear than ultralight hikers.

  • 62% of lightweight backpackers spend >$1000/year on gear
  • only 12% of traditional backpackers spend >$1000/year on gear
These ultralight backpackers also have a relatively high household income. Of lightweight backpackers, 58% have higher than $70,000 annual household income. Backpackinglight.com's research also suggests that lightweight backpackers influence other buyers by having a high participation in online gear reviews and being more likely to participate in face-to-face gear talk. Lightweight backpackers also have a tendency to shop at highly specialized retail stores. These stores (in my experience) have poor selection, biased staff, and highly inflated prices.

The recently released 2011 Outdoor Foundation's Research Participation Topline is rating hiking as the 5th most popular outdoor activity among people age 25+, with 22.8 million people participating in the US. With such staggeringly high participation, it's pretty obvious that outdoor lightweight specialty brands, products, and retailers have a lot to gain (your money) by keeping the newest, most expensive model of lightweight hiking gear hyped up for consumers to purchase.

Remember, do your homework before you buy. You can almost always find a better deal on gear online than you can if you walk into a store. Be careful who you talk to and what store employees suggest. Their interest is in your money, not your products. As a frugal shopper, and poor college student, trust me when I say it pays off to shop smart.

Neo Air Competitors: Peak Elite AC, Ether Elite 6, and SynMat

Don't have the money for the listed retail value for Therm-a-Rest's new NeoAir? It's $150 retail price and guess what Cascade Designs forgot to do again? They forgot to include a bag to put your NeoAir in. "That'll be $15 extra, please," says Cascade Designs in their ongoing low-blow marketing scheme. Come on guys, who sells an unfinished product? And we all know that's what an inflatable mattress without a stuff sack is: incomplete product. And if you haven't read all the bogus reviews, the frequency with which the internal baffles "pop" on the NeoAir is absolutely unacceptable for a mattress with a $150 price tag. Overall the NeoAir is too expensive, poor insulation, and terrible durability.
I'm going to do all of you NeoAir freaks a favor and expose you to a few more economical choices that rival, or surpass the features of the NeoAir. Here they are.


Pacific Outdoor Equipment Peak Elite AC
The POE AC has got the NeoAir beat hands down. It should be available early spring 2011. Here's the quick and dirty:


  • Peak Elite AC = 15oz (L) --->  NeoAir = 19oz (L)
  • Peak Elite AC has vertical baffles ---> NeoAir has horizontal baffles

        *Horizontal baffles allow the pad to conform to your body shape better and hold you in place

  • Peak Elite AC R Value is 4.4 under the torso and 2.5 on extremities ---> NeoAir R Value is 2.5
  • Peak Elite AC pad size 20"x78"x2.5" ---> NeoAir 77"X25"x2.5"
        *Peak Elite AC is narrower, however the vertical baffles help hold the sleeper on the pad, thus
          allowing the pad to be smaller while still being effective. Plus the shaved down size also shaves  
          weight.

  • Peak Elite AC and NeoAir are both manually inflated, meaning you must blow them up like a ballon.
  • Peak Elite AC pack size 4"x12" ---> NeoAir 4.5"x11"

Pacific Outdoor Equipment Ether Elite 6
Extremely similar to the POE Peak Elite AC, the "old" Ether Elite 6 has all the same features except it lacks the new "Radiant Heat Return" technology. So a slightly lower R Value. However the Large EE6 was priced at only $69 versus the NeoAir's (large) $169. That's a huge difference! And guess what? Pacific Outdoor Equipment didn't try to cheat us out of a stuff sack, they sell those with their products. Wow!



Exped SynMat Basic 7.5
Is now available for purchase! It's heavier than the others we've talked about but it's 3" thick instead of 2.5". Exped boasts an R Value of 4 for this mat which they rate down to -11º C (12º F). It comes in at 9.5"x5.7" packed and 71.5"x19" as a mat. It's narrower, yet, than the POE AC, and 6" narrower than the NeoAir.
Exped's sister series; the SynMat Pump is a bit heavier but has higher R Value and, you guessed it, an air pump to fill them up.
