The new Jetboil Sol is reasonably light - 260g

Nice! I've always kept my jetboil because of the convenience. Might be time for this upgrade when they are out

Thanks. I think I'll get a Sol-TI and leave behind the bottom cup and sleeve

9.17 oz. seems reasonably light for that set-up, assuming it includes an insulated cozy and sippy-top lid. The pot portion is reported to come in at 6 oz. and the stove at 3.17 oz.

I wonder if the titanium pot will perform as well as the aluminum one. The Ti does not hold the heat in as well due to much lower thermal conductivity. Sounds like a good test fo BPL!

Brian, it has been considered and tested fairly extensively here in the past, especially by Roger C., if I remember correctly. There is also plenty of anecdotal evidence that seems to suggest the difference is minimal (less than 2%); however the flux ring should likely still be made of aluminum.

"...however the flux ring should likely still be made of aluminum."

Why is that, Aaron? Wouldn't titanium hold the heat better, thereby being more efficient? Or am I missing something here? Maybe that would overheat the canister below?

You don't want the flux ring (or heat exchanger) to 'hold the heat' - you want it to conduct the heat into the pot. Ti is a very poor conductor of heat.

cheers

TI pots will be stronger for the same weight as aluminum, but not a deal breaker for most people.
If you really have to cut weight and not end up with a crushed pot from careless abuse, I vote for TI.

By the way, copper is a better heat conductor than aluminum. A thinner copper foil may be better for a flux ring?
Copper is heavier, but a thinner foil can be used.
I know the aerospace industry uses it for heat conduction over aluminum when gold is too expensive.

Maybe a gold foil flux ring for the elite:-)

> copper is a better heat conductor than aluminum

True, but aluminium is lighter than copper by a bigger factor. It wins.

Cheers

Isn't copper also more expensive than aluminum?

I remember someone saying that although copper is heavier than aluminum, it is used in aerospace technology because much less of it can be used to transport heat in electronics and the result ends up being lighter.
I think silver is even better and gold is the best.

And yes copper is more expensive than aluminum and of course silver and gold out of the question.

Though when it gets down to it, aluminum is probably the best choice for a heat exchanger as copper would need to be very thin and fragile.

I wonder about using very thin copper pot or a copper clad titanium or aluminum pot to reduce scorching for those that don't freezer bag cook?

Looks like the specs are out for the 2011 jetboil stoves

So 9oz for the TI setup and 7oz for a fuel canister? 1lb for 1.5 weeks of breakfast and dinner. Jetboil moving on up to Westside.
