Do you have any videos of this beast in action? To suck up my pride, I really don't understand how it works.

Hi David:

Sure! I really need to make my own diagram of the anatomy of a chimney kettle.

Here's a video of my prototype in use: http://www.theboilerwerks.com/2010/05/rainy-day-hot-tea/

Here's a page with Thermette's diagram: http://www.thermette.com/thermette_history.htm

Edit: didn't regular old html links used to work on here?

Edit Edit Hmm: link. I swear that didn't work the first time. :)

Hi Devin
Great video. Yes you are correct you did not need to blow on it 'cause you had no marshmallows to toast...
I used the Thermette (2 L) about 30 years ago and yours pretty much works like that one.
Probably the easiest wood operated burner as there is no skill at all involved in lighting that up and keeping it going.
Well , very little anyway.
Very much looking forward getting mine.
Job well done !

Thanks for the links. That makes things quite clear. What a cool device. I love how light and compact it is.

Now, if I can just convince myself that it's worth violating the law to use (wood fires are generally illegal in Southern California except in developed campgrounds).

Thanks for the explanation about the neoprene. I'm won over enough that I ordered the deluxe version but I'll probably mostly eschew it. (But maybe a little Thinlight CCF?) Looking forward to trying it out.

BTW my own can-ufactured alcohol-burning kettle is described here. I'd like to bring that project home to field-usable completion one day if my fabrication methods can be improved, and the burner design optimized, so that it could survive packing. Just about 2.3oz heavy.

(Don't sweat the misspelling. My name gets misspelled all the time, but usually it's my last name.:)

Tim & Eric: I feel like you two should talk. You know what would make the boiler "no fires" compliant? An optimized alcohol burner that could achieve better than 50% efficiency. :)

Fred- Absolutely, I had actually been thinking about this. I don't think the good vibes, heartfelt thanks, and any other intangibles you all receive from giving me a gratuity are subject to import taxes. So I'll just list the amount you were required to pay.

Kind of fun to have an Fred Eric and an Eric Fred(ricksen) on the same thread. :)

My kettle was 41% efficient in my kitchen. It's possible that enough tweaking could get it to 50%. Who knows? Iterating is difficult, and I don't have your attention span, it seems. :)

What's the thickness of your aluminum, Devin? I'll guess 2 or 3 times that of AL cans?

Also, is the fire bowl AL too? Doesn't it burn up?

Could not resist! Just ordered one up, the fact that you are only 26 away from 100 also sped it up. Can't wait to brew a little cup while fishing!

Only 24 left now. I'm not sure if that counter is "live" but 2 were sold while I was browsing his videos.

Hmm. So maybe a little alchy stove could fit in the burner area? Hmm.

what method of shipping would you use to go north of the border? usps would be preferrable since private couriers do their own brokerage and charge outrages fees, especially ups.

Hey all!

I'm actually working on a presentation today (still in law school until December, after all) so I won't be too responsive until tomorrow, but I wanted to offer some updates.

On the fire bowl thickness: this is actually still in flux to some degree. In its thinnest possible iteration (what I've been using on my prototype), it's been fine through 100s of boils. The heating soft tempers the Al (so don't bang it against a rock to remove ashes), but the time it's expose to these temperatures is relatively short under normal use. Physically, you'll notice some softening between boils 0 and 1, but I have noticed no appreciable difference between boils 1 and 100. The kettle does not experience the same changes because of the heat sink effect of the water.

On availability: the numbers on the site are quasi-real-time. I update them when I see that I have a new order.

Shipping to Canada: Most likely USPS. Unless I see a reason to do otherwise, USPS is the way I'm going all around, with a 3d party providing shipping insurance where necessary.

I can see that many of you have been recommending these to friends and other little virtual communities on the web. Thanks so much! It's humbling to have such support.

Quick question on 11/18/2010 12:25:55 MST Print View

Can you use a regular stove (canister) to boil up the water. How about alcohol stove?

Only 12 left and that doesn't include the order I just placed. Better get a move on if you want one.

Yep - I've with a modified White Box alcohol stove and I'm sure the same could be done on a canister as long as the support progs are more than 4" from tip to tip. I've actually used it on a really regular stove (as in a range top). The challenge is for the flames to flow up the walls of the conical chimney rather than just straight up and out.

Only 4 left to go!

I won't get one since a) wood fires are generally illegal in Southern California and b) I frequently hike above tree line when I go up further north to the Sierra, but dang they look cool.

Devin, I think it's really cool that you've been able to design, prototype, and now basically bring to market such a great addition to the stove world. My hat is off to you. Good luck and God speed.
