Home Forums Hunting & Shooting Backpack Hunting tipi light w/o batteries

Way back when on another forum there was a discussion of using the stove for a tipi light. I think glass window in the pipe was tried but it got too sooty. I suggested a thermocouple driving an led lantern. Metal thermocouples are not efficient enough. I just ran across these solid state thermoelectric devices. I think they might work. Maybe try it out when I get time.

Constructive criticism(sp?)

#1: The unit cost $50. You can buy a few Lithium batteries for that.
#2: It probably weights more than the battery.
#3: Specs are for a 200�C differentail. You would need a heat sink (more weight) and or a cooling fan to achieve even close to that I think.
#4: Its rated for 260�C (500�F). You would have to be carefull not to cook the thing. If the tinfoil stove got red, that thing would suffer.

It sounds like a cool idea, but I think power generation will be hard to achieve in as light and compact a package as an LED light with a battery.

I played around a bit cooling overclocked CPU's with Peltier (simmilar device,opposite effect) coolers and copper heat sinks with cooling water flow. It was fun but hightly impractical.

What is wrong with the candle lantern? Not a whole lot of light, but no batteries.

Does anybody know of a company that makes a lantern to thread on these??



I've got quite the pile of mostly used up ones. I was thinking more for Fly-Fishing camps than backpacking... But who knows, with a big enough group of guys it might go hunting too

Brunton does.

No experience with them, however.

Good points. Thanks. The parameter of the original discussion was to have light source as long as you had wood, essentially indefinitely.

I'll have to think it over before I blow fifty bucks. I don't need 5 or 15 watts, more like a hefty fraction of that for something like a brunton led lantern. So I don't need to run it at spec.

Dude,


Thats exactly what I was looking for




Thanks..

Don't forget Snowpeak: Giga Lantern

I almost bought one but my Zebralight is more than sufficent.

Primus makes a small but bright, lantern, and I prefer it over the Snowpeak or the Brunton. comes in a durable hard plastic case.

Heh, somebody caught on.

I wonder how that works after a week or so of heavy rain.

I have to throw my vote to the primus lantern. It is small and bright and in a one or two man shelter will take the chill out of the air. Just remember to be carfull about carbon monoxide.

husky.

I have tried a bunch of things and nothing beats a good LED flashlight with DIY diffuser for a UL bright option however this takes at least one battery. I use LSD NiMH that could be recharged in the field with my fold up charger or at home for guilt free lumens.





But then again a candle lantern is kinda nice as it adds maybe 5 degrees to my shelter and is one of the few things that actually works better in the cold. It goes without saying these are battery free.
