Hey Brad
These stoves are a lot of fun to build and "play" with. But alcohol stoves have an added danger other liquid fuel stoves dont share. Alcohol burns without any yellow and sometimes without any blue flame.
The stove can be lit and the camper can get burned because you can't see the flame and so reach into the flame or the camper makes the terrible mistake of openiong the alcohol bottle and tries to add more fuel. An intense fire can follow.
If you know the risks these can be light weight functional stoves. I have used them hiking often.
I would never use one in a TD however. Not even in the back galley area of an open hatch TD.
Here is why...
Alcohol fuel is very volitile. More so than gasoline and much more so than kerosine. Spilled liquid evaprates almost instantly and it looks like it is gone. But the flamable vapor isn;t. The vapor is heavier than air and it will flow to the lowest drawer, cabinet, or cavity in the TD. When you light the stove the vapor trail will also ignite.
In MHO these tiny alcohol fuel stoves are not for children to play with or use.
I only use the can stoves in completely open areas out doors. Even then I am always careful about what is "down terrain" from the stove.
By the way...
There are fewer hydro carbons in alcohol fuel than white gas etc. There for it takes more alcohol fuel / unit of weight to boil water than white gas propain etc...
Have fun! Be safe! Camp Happy!
