Boil time for pots made from different metals

For years I have heard that aluminum pots are better for backpacking. While the aluminum weighs more than titanium, aluminum will conduct heat better and thus boil water and save fuel. Less fuel means less weight overall.

I decided to test which whether what I have heard actually proves out.

Here is what I did. I setup my MSR WhisperLite Internationale stove on my back patio.

Altitude:             4500ft
Ambient Temp:  48ºF
Water Temp:       37ºF
Water Amount:   500ml
Wind:                  15-20 mph

Pot	Weight	Boil Time (hh:mm:ss)
Peak 1 Stainless Steel	341g	00:04:30
MSR Quick Solo Aluminum (Hard Anodized)	220g	00:03:30
Optimus Terra Weekend HE (Hard Anodized)	278g	00:03:20
MSR Titan (Titanium)	341g	00:04:30

Weights listed are just for the pot, lid, and the pot lifter for the Titan pot as seen in the video.

Extending the Sawyer Squeeze

As spring struggles to make an appearance, I have begun taking short excursions in the foothills that surround my home. I generally tuck a Sawyer Squeeze into my hydration pack, just in case those ice cold mountain stream calls to me.

After my most recent trip, while drying the squeeze pouch I began to wonder about using the Squeeze as a gravity filter.  With the Squeeze connected directly to the two liter pouch the water flow using gravity is minimal. I retrieved from my gear, my Sawyer Inline Hydration Pack Adapter, and a replacement MSR AutoFlow hose. I removed the connector from the 12 inch AutoFlow hose piece. Placed the hydration adapters on each end of the 12 inch piece. Removed the bite valve from the squeeze and fit the long hose onto the nipple under the bite valve. Used the included pinch clamp to shut the hose down, and attached the completed squeeze/hose to a two liter Sawyer pouch. I essential built the same configuration that every gravity fed system uses. I released the pinch clamp, and started a timer. It took 1 minute and 26 seconds to empty the pouch.

My fastest gravity filter takes 1 minute and 15 seconds to empty a two liter pouch using a .2 micron nominal hollow fiber filter. The Sawyer Squeeze is a .1 micron absolute hollow fiber filter.  My gravity filter is rated at 1,500 liter cartridge life. The Squeeze at 1,000,000 gallons cartridge life.

A little nostalgia

Over the weekend I had the time and inclination to dig through my accumulated backpacking gear. It is amazing to see the changes in gear. I started backpacking in the early 1970's with a home made pack, pup tent, rectangular flannel sleeping bag, and an old aluminum mess kit. Dehydrated food was either too expensive, too tasteless, or unavailable.

My home made pack, gave way to an H-frame without hip belt. Then I added a hip belt, which then gave way to an internal frame pack.

The aluminum mess kit gave way to a stainless steel kit. Stainless steel turned into hard anodized aluminum. Hard anodized aluminum became titanium.

Open fire cooking turned into a Peak 1 400A stove with a factory windscreen.  Peak 1 gave way to a WhisperLite International.  The WhisperLite into a canister stove. Canister stove became an inverted canister stove. The inverted canister stove morphed into a stove system.

Drinking water straight from the source gave way to a ceramic filter cartridge.  The ceramic filter changed into hollow fiber.

Rectangular sleeping bag became a synthetic mummy bag.  Synthetic bag gave way to a water resistant down bag.

I have kept each item, and each item is still completely functional.  I still use my 20 year old WhisperLite (with original pump) for winter camping. I have, however, given up lugging the Peak 1 stove around.  I have also given up lugging most of the older equipment. You couldn't pay me enough to carry the steel framed home-made pack again :)

My point here. You do not need the latest greatest equipment to have an enjoyable time in the back country. Get the gear that works for you and your budget, and go have some fun!

What is the best ...?

When friends, acquaintances, and coworkers discover how much I enjoy backpacking I am often asked my opinion on specific gear. The question usually comes as "what is the best water filter, stove, backpack, etc.". I sometimes feel that the question is unfair, and very similar to asking someone, "what is the best car?".  As you can imagine, if there was only one best car, everybody would be driving the same vehicle.

Over the course of many discussions I have come to the conclusion that my best response is to ask another question of my own. "What is your budget?". Then I can narrow into some items in their budget and maybe add a little knowledge of the pro's and con's of the items.

There is not a perfect stove, nor a perfect water filter. You must make decisions based on your use patterns and budget.  Remember, a higher price does not necessarily indicate a better item.
