Stove Testing

[sudden]

Very nice chart.

Can you plot another showing total weight (stove, windscreen, etc) vs. trend line?

I'd also like to know the percentage gains/losses? of the fastest boiler vs. the most efficient fuel user. (off to find my calculator).

[sudden]

OK, if I did this correctly, there is a 50% gain in boil time vs. only a 25% increase in fuel usage from the fastest boiler to the most efficient user.

[sudden]

I probably should have said boil speed

Nicely done!

Slower to boil on the bench means greater amount of fuel needed in the field and a greater amount of windscreen protection and insulation from cold ground in the case of the Ion and any other stoves that have statistics similar to it.

I have been staring at this graph for several hours and here is my takeaway

I thought I had too much time on my hands, you got me beat by a mile or two.

You got to read this thread submitted by tony. He really knows his stuff. Stove "Geek" representing the "Land Down Under" Australia

This chart is really valuable stuff!!!
If you have extra half an hour, could you (please, please) also measure the ordinary tealight stove, no WS, in your experimental setup, as a "common reference point", so that we can calibrate your results to our individual setups?

I think that would be a big help. It would be the smallest stove used by some hikers.

2 inches? Everybody is ok with this?

Not for me. I suggest 1" from rim of burner to pot.

[zelph]

I did 2 burns this morning. The ground to stove distance was 2" as this is what Jason Klass used in his Klasslight design. The tealight is 5/8" high so the stove to pot distance was 1 3/8".

15 ml boiled 2 cups of 70F in 9:30 with a FO @ 12:00
14 ml boiled 2 cups of 70F ibn 10:10 with a FO @ 11:20

OK, a single run was collected @ 1" stove rim to pot:

14 ml boiled 2 cups of 70 F in 10:20 with FO @ 11:10. This seems reasonable the height difference between this data and the original run was only 3/8".

I combined both tests with high lite in red.

So it seems the pot support can be lowered to 1" and all will be well. More compact and a fraction of a gram less.

1" is what the pot support is on the StarLyte which has a 2" dia. burner.

Thank you for adding the 1" support to your figures
