    Try it with both heights (take the seal out to protect it?). Same amount of water and fuel, the time it?

    But if you're like me, don't expect to remember to take it out every time if you're using it on a regular basis :oops:

    This thread has just reminded me I have to burn off whats left in me speedster open top stove from the other night, cheers! :thumbsup:
    Time for a cuppa me thinks.

    Stormin stove is about 30mm although the mesh is about 27mm, speedster 30ml is about 20mm.

    I guess I'll have a play and test it myself. Did see this on stormins page though:"They have the advantage over the lower height wick stoves used with a bottom vented windshields. Commonly between 20-25mm high they are in direct line of incoming wind fluctuations, causing flame disruption and uneven heat conduction"

    Once the shops are open buy the cheapest/ flimsiest silicone baking dish you can find (Poundland, B&M, Home Bargains, etc) & cut a replacement seal from that; I think I got the last 20cm diameter flan type dish from Poundland.
    I also punch a small hole in the centre of the seal as I've found that if you screw down the lid when the stove is still hot as it cools the silicone disc gets 'sucked' down breaking the seal.

    If the tests indicates the height makes a difference I'll go down that route @Whiteburn

    Do you know what the distance between the top of the mesh & the base of your pot (the flame gap) is? I have the flame gap for my speedsters at 35mm I think off the top of my head, open top burners tend to give a high flame & with the wick the flame stays at the same height until nearly spent I find.
    Can't comment on the stormin cones, but I haven't found the lower burner to be any problem with the cone made using captain paranoia's script.

    I replaced the seal with a silicon disc cut from one of those small oven glove things, seems to be OK.

    Silicone seal has a number of benefits: the silicone is easily good for 200C so you can get the top on as soon as it's cool enough the handle, saving fuel; it seals reliably (unlike the cardboard) to stop ethanol vapour corroding the threads

    Every stove seller reckons theirs is better/different than the others.

    Personally I think the (lower) holes on Stormin cones and windshields are unnecessarily large and let in too much wind. Homemade cones using smaller holes by standard paper punches let plenty enough air in and are more wind resistant.

    The light wind today was definitely getting in my to stormin' cone, but to be fair the hex was in a low sided pot.
    The holes do look quite big.

    The TD cones have always delivered for me irrespective of stove and fuel choice.
    Not used, nor will I, the alternatives.

    Yep. Also what Ed says. After years of using homemade aluminium cones (using Captain Paranoia' script - as plagiarised by Stormin), I coughed up and bought a Trail Designs Titanium Sidewinder 3 years ago. And another for a smaller pot this year. The dovetail joint is so well made. They have narrower vent holes too.

    Yes it will damage the lid seal (as I found out the hard way).

    With this talk of CP, it got me thinking, did anyone here ever try to make one of his Squeezbox stoves?
    I remember Paddy Dillon used to use one, but can't remember anyone else who did.
    Don't know why I thought of it really, just that I remember it being a nifty design & I went looking for it with no joy as the page has been removed from OM. :(
    edit: found it on zen stoves https://zenstoves.net/PotStands-WindscreenStands.htm about 4/5's down the page

    Finally got round to this.
    Stormin alu cone, base plate, alpkit 900ml ti pot.
    Bio-ethanol fuel. 500ml boil test

    Speedster 30ml - 12g 7:30
    Stormin stove - 13g 9:00

    Conditions wern't identical as I tested Speedster before bed and Stormin in the morning but temperature read 4C for both.

    Not a perfect test but enough for now to convince me that the difference is negligable between the two with speedster perhaps being faster despite the height difference, might do more comprehensive testing with the speedster height and include the stormin cone stove aswell in the future.

    With the TD cone and a Speedster, I've found that increasing the height can speed up the boil with negligible effect on the efficiency, up to a point. I also found that it can lead to soot on the pot unless I increased the number of oxygen holes. Whether you find that may depend on your cone. Also, your pot is wider (and thus your cone) so you may not have the same problem.

    I must be bored due to lockdown, but I thought I’d post my experience with my MYOG alcohol stove (I’ll call it the Turbine stove due to the intercalating ‘vanes’). The efficiency really impressed me versus any other stoves I have used in the Flatcat Snow Leopard system and Trail Designs Sidewinder (the latter with 600ml Evernew pot). But I thought I’d also test it versus a simpler version in the same container (see photo) – maybe not with the results I expected

    The stove was made with an aluminium container with a top containing a transparent plastic insert (which I removed). Using some metal from a drinks can, just cut a circle and then cut 8 or 12 ‘slices’ towards the centre (not all the way of course), then carefully cup the sections so they slide over one another as you insert into the container and hold secure by inserting the cap. The idea was to do something similar to the Flatcat stoves with an insert rather than folding in from the outer wall, to enclose more of the fuel within the stove, and make it slightly smaller and lighter than the Flatcat stoves. I’ve been using this as my main stove for 2 years and found it more efficient in both systems I use than any other stoves I have.

    So, yesterday I decided to compare this stove with the empty container it is based on (without insert), and it was a bit of a surprise (all with 400ml water, 14g bioethanol, indoors; Snow Leopard system)…
    Turbine Stove: 8min 30s boil, 12min 20s flame out
    Empty container: 8min 10s boil, 12min 5s flame out

    Almost no difference, although because the fuel does slosh around inside the empty container version I’d still choose to use the Turbine burner – but the ‘engineering’ seems to do little in terms of performance. Will it be different in real-world conditions? I wonder if the apparent efficiency is just a function of having the right stove-to-pot distance and stove output (most of the others I have are more powerful).

    I can send you some ceramic insulation to stop the slosh if you like, then you'll have a no-spill wick stove commonly used by a lot of alkies. Starlyte/Speedster/Kojin etc.

    Thanks for the offer @Mole. I probably should have mentioned that I'd deliberately chosen not to go the wicking stove route. The Turbine stove has no issues with 'sloshing', is super-easy to light and you can see how much fuel is left.
