Ethanol? Ethyl Alcohol? Pure etoh(well, 95 percent pure...)?Originally Posted by Miguelon
Why? So you can make a cocktail after you light your fire?
The lightest backup fuel for a woodburning stove IMO is Esbit (in terms of heat output/gram fuel), but alcohol is easier to find in many locations. Both can be used in most woodburning stoves that have a multifuel option.

Thanks Qiwiz... I'll look into that.

Have you compared WetFire to Esbit? I am betting WetFire burns hotter, but shorter...
I have not made the comparison. Efficiency (in my general experience) tends to increase when a burner is less hot but burns longer, so a hotter burn for a shorter period of time might not be a good thing. I'll leave that to others to sort out. An Esbit tab weighs a half ounce. A full tab will usually boil 3 cups of water with good wind protection and correct pot height over the burning tab. That's good enough for me. For Esbit cooking I generally budget 2.5 tabs/day (1.25 oz fuel weight/day) so that I can have plenty of hot drinks along with a cooked breakfast and dinner. When using Esbit as a backup to wood burning, I usually just add a couple of "in case I need/want it" tabs to my kit, for a total weight penalty of an ounce. Just sayin . . .

Hi QiWiz! guess what, I am about to build a Sea Water Desalination pot that works with the larger stove. I have ordered a specific pot that will arrive in the next two days and I am putting together a nested pot, coil, and cup. If I get anywhere I will send you a video.
I have a second idea to convert seawater to fresh, but requires a lot of metal work that is beyond me and would work with a single pot of any kind.

Dogs are excellent judges of character, this fact goes a long way toward explaining why some people don't like being around them.
Woo
Three cups of water to boil on one esbit tab; you've got to be kidding? I challenge that assumption. My trials punked out with two cups of water and one tab under controlled conditions. I find esbit to be frustrating and worthless except for reheating previously prepared food, which is what it was designed for.

With this set-up, Toaks 900 and a DIY windcreen/pot support, I can consistently get 3 cups of water to boil easily with 1 regular size esbit under ideal conditions.

Challenge you can. Pot height and wind protection are critical to success with Esbit. I am not lying when I say that you can boil 3 cups with one tab. Get a Caldera Cone setup (or a similarly well-crafted set up, see Zelph's post) and you will be convinced. When out west above tree line, I have done many extended trips with Esbit as my primary fuel. For dinners I usually boil 4 cups (2 for food, 2 for beverage). With 1.5 tabs I bring 4 cups to a boil and have 3-5 minutes of simmer time before the Esbit is used up. No lie.

Using the same set-up as in the above photo but substituting the pot to be a kmart grease pot, I could get 4 cups to 190 degrees using 1 regular size esbit. I used a Brian Green Esbit Tray(BGET) with bread pan corners to hold the esbit while it burned. Esbit has POWERAdd another 1/2 cube and it's easy to boil the 4 cups and simmer as QiWiz has stated.
