"That is where my thought went for my Long Trail hike.. 1 100g canister went the whole way. 16-18 boils and still has some left. equivalent of alcohol would have been heavier, slower, and more finicky. a few more ounces for a canister stove is worth the aggravation for sure."
I did the Long Trail too, with my Esbit stove (admittedly the 3 oz version before I switched to the 0.3 oz titanium. Restocking every 4-5 days, which is necessary because of food, meant carrying a max of 70 g of fuel at any given time, usually less. My total stove+fuel kit, when restocking every 5th day, weighs 78.4 g on the first day and 8.4 g on the way out, which is significantly less than a canister stove could ever weigh, until they come up with a new kind of canister. Admittedly, if you're in a situation where you can't restock except every 16 refills, the Esbit option would weigh 232 g. However, at that point you've got over 30 pounds of food on your back, so you'd probably not notice.
Not to say that canister stoves don't have their place, which they do. I have one within arm's reach at the moment. It weighs much more than the 41 g of this new device.
I was mostly just making a wisecrack. And for the record, my interpretation of the phrase "World's Lightest Tent" is actually more like, "Extremely heavy poncho-tarp (without the poncho)".
