- Get You Own PaleoHikerMD Patches HERE!: www.etsy.com/s... I recently did a video on using a windscreen with a canister stove safely, and many commented that using a windscreen is essentially mandatory with an alcohol stove. Now on this channel the proof is in the pudding, so let's put it to the test! And not only that, but let's test 2 different windscreens!

4:25 This tall windscreen is upside-down. The slots in the top should be at the bottom, to allow fresh air to come in the bottom of the burn chamber.
Might have been even better.
I noticed that too. I suspect the boil time would get reduced even further, but fuel usage probably creeps up 3-4 grams. Good eye on your part.
Glad I watched it. I have been using a aluminium foil screen. I wrap it closely around my pot. Definitely Boils faster.
@PaleoHikerMD Windscreens do more than block the wind. They also keep the heat against the pot walls AND they reflect the heat back to the pot. Like a sun oven, the more reflective the surface of the windscreen, the higher the reflected heat will be...which translates to faster, more efficient boil. The height of the windscreen should be equal to to the "full line" of the pot. Extra height provides no noticeable benefit and adds unnecessary weight to the pack. Aluminum foil is popular for DIY, but I prefer windscreens made from the shiny "dollar-twenty-five store" cookie sheets that are sold in 2-packs. They are more rigid, easier to manage, and the offer the same reflectivity as a solar oven. Additionally, they can be used to pasturize water (in a clear bottle) simply by laying the bottle in the windscreen in full sun, similar to using a solar oven.
One other consideration is the pot. The shinier the pot, the more heat it reflects away. Dull, darker pots absorb heat better, leading to faster boil times a greater fuel savings. Ever wonder why those ratty, dull aluminum cookpots we used to use boiled water so much faster than the shiny, stainless stuff sold at stores today? Not only does aluminum conduct heat better (think heatsinks), but the dull surface reflects less heat away. That would make a great video, btw. Appreciate all your videos. Be safe, brother!
Really great to see a scientific test. Would have been nice to see the results summarized in a graph or chart.
If a aluminum foil wind screen the fuel savings would more the make up the weight of the windscreen.
I always use windscreens with all of my stoves.
Yep. That is all I use. An aluminum foil windscreen and a couple small pieces of steel wire with 90 degree bends at the top to hold it in the ground on extra windy days.
I was impressed by the diligence with which you attacked this issue. Thank you!
Tall Windshield is upside down.
Good test and video. An inside test with a fan blowing a constant stream of air would make a clearer difference on the benefit of a windscreen. With zero wind it might be lighter to not have a windscreen and carry a little more fuel, and with a certain amount of wind it would be 'lighter' to carry a windscreen and less fuel. A windscreen is reflecting some proportion of radiant heat heat back of course.
I found enclosing the tall windshield fully around the pot and stove as you did drastically slows the boil. I too have a tall windshield and now leave the front of it open a couple of inches or so, with far superior boil times. Guess your sick of hearing you got it upside down tho....lol Entertaining video all the same God bless buddy....bex
Truly excellent experiments, thank you!
I was considering reducing the height of my tall windshield to fit it easier in my stove pack - I won’t be chopping it down after seeing this video. Great work! cheers
I would also like to see a comparison of boil tests with the best performing windscreen vs the Caldera cone.
Great video..especially like the difference with the higher windscreen. Very useful.
Interesting. Pretty sure I would have not thought to use my windscreen on a still day. Thanks!
Works 2-fold. Keeps heat against the pot wall, but also reflects heat back to the pot. The shinier the windscreen, the more efficient it is.
Working on alcohol/ remote canister Trangia knockoff,Trekmate brand cook kit ,near Trangia(?),Trangia stove,and knockoff canister remote.All in,60$,we'll see how it goes!
Can you do the experiment again but this time with a strong wind. The results could be hilarious.
Wow. That’s useful info. Thank you.
Tall windscreen was upside-down, cutouts should be on the lower edge to feed oxygen to the flame. Please test that out.
Thanks for sharing
Take care
Excellent test, just what I was looking for, many thanks from across the pond.
Helpful. I’m feeling more confident about trying outdoor cooking.
Hello my outdoors friend, thank you for sharing this very informative alcohol stove test. Be safe out there and keep those great reviews coming. 🤗
You put the large windscreen upside down and left the air intake holes up top. You would have probably gotten a slightly faster boil with proper airflow.
Great test. Thanks
Great test, Thanks 😊
great reasearch. thanks
Would a wind screen in the absence of wind be a heat concentrator. ;)
It's keeping the thermal radiation of the water cup "inside" rather than radiating away.
It probably doesn't matter much but I think the notches on the top of your tall windscreen go on the bottom.
Noticed that as well. Those notches have a purpose and do help to create a chimney effect. Actually, unless you use your windscreen upside down, the notches ARE at the bottom.
lapicker I noticed that too .. then saw the crack in the table top (only in that trial) and figured that took care of that ...
I've had problems with my alcohol (toaks titanium) stove in strong winds, it basically doesn't work withouth the screen, in those conditions.
Very good video!
Nice job,. Informative. I am getting ready to build a windscreen. Now I need to decide how tall. Thanks,
Frank
Maximum efficiency is achieved when the windscreen is the same height as the pot. However, there is no noticeable difference with windscreens past the height of the "contents" in a filled pot. Ie...if a pot is full 1" from the top, that's approximately where the windscreen can stop. Windscreens taller than the pot have inherent safety risks when trying to access the lid. They are also easier to knock over or blow over, plus it's just extra weight and space in the pack. Happy packing! Stay safe!
What kind of alcohol?
Good Video .. thanks for sharing.
Great Job. Thanks. How effective can the alcohol stove cook setup become?
Not all stoves are the same. Most sacrifice total burn time when they offer shorter time to boil, at least that is what I've seen with Caldera cone tests.
Good❤
Boil 2cups of water (500ml)
No windscreen 8:50min 22g fuel used
Windscreen 7:26 20g fuel
taller windscreen 6:25 17g
Notes:
- windscreens were upside down. Results not trustworthy.
- results are biased as they largely depend on how close the windscreen is to the pot. Snug=more heat transfer=fuel efficiency.
- low wind conditions here means results are more noticeable in windy conditions.
Result: completely worth bringing a windshield unless you have a shelter tarp/awning and cook in it.
In a breeze you will see a significant difference.
Is there a minimum of fuel that the stove needs to have?
Where are the results of the tests?
trust me when you're in high winds you need a wind screen
very good test! I needed this nfo today. thank you.
how are gonna see if you need a wind screen without any wind?
He just did it in the video! Did you watch it?
He pointed out that there was NO wind and got an improvement in the shorter boil times.
Besides block the wind, the windscreen reflect heat to the stove - helping in alcohol vaporization, and to the pot.
Will you repeat on a windy day?
yeah add wind.. thought that's the whole point of the protection.
An electric fan for consistency
Nice shirt.
Cool
👍👍👍🔥🔥🔥
Good review! would vargo wind screen work with Evernew stove with cross stand?
It should, thanks for watching!
Hi. I was wondering if possibly you coudn't just put the alchohol stove into a bigger rounder can which could act as a wind screen and a stand as well though you might have to put holes in the bigger can so it doesn't smother the alchohol stove as it burns. What do you think? Would this work? I have not tried this yet, only in theory. Putting your stove Inside a bigger can would protect the alchohol stove from wind and be a stand as well. Killing two birds with one can.lol.
You mean like the Toaks Ti stand? or the Trangia Triangle?
Evernew DX stand is what you think, the two round parts is pot stand and windscreen.
No alligators in the drink behind you is there?
Dont like that screen
.
Does this pass the "SO WHAT" test?
minibulldesign.com these people make and sell the best alcohol stoves...and they are all made in the USA. . .and are the lightest and hottest on the market...A Carbon fiber wind screen is the one you want to use with an alcohol stove...
