I tried googling this question and searched on here.
I was curious if one could use isopropyl alcohol or dentured alcohol in a rocket mass heater as the fuel source?
the reason I am asking is if this is possible then perhaps one could build a small version of a rocket mass heater but have it vented on the inside (no danger in fumes?). I have found through google searching that the byproduct of alcohol is carbon dioxide and water. none the less, the fuel source I was thinking about was a small tuna can with toilet paper stuff inside and soaked with alcohol. desertsun02 - on youtube has made several of these heaters using rubbing alcohol and toilet paper with different sized cans:

has anyone tried this before? burning alcohol as a fuel source in a rocket stove?
in another video (a little off subject) desertsun02 made a small heater with a galvanized stack boot and a 90 degree elbow using alcohol as his fuel source. I got to thinking about cob and thermal mass and had an idea - what if one were to place cob around the metal piping design he put together? Would this be of any benefit? here is the video:

This one batch type is runing on alcohol for some testing.
Tho venting inside for few minutes, and using it for heating is a different thing. I've seen thoses "fireplaces" run onto alcohol, that they have released lately in France. And i don't believe they are that safe.
It's like Kerdane stoves, which are vented inside. I have had one, and can tell you; you get a headache after runing one for only few hours.
Plus, runing on alcohol wouldn't be too ecological imho.
Allen Sharp : SoneEarly internal combustion engines had very short intake manifolds and inlace of a carburetor a cloth saturated in kerosine. This was an early
attempt to atomize the fuel to get a clean burn!
The biggest problem you have is atomizing your alcohol fuel, inspire of its low vaporization temperature !
You will ether need to spray it through a nozzle or use some kind of Electronic fuel injection. Also you are trying to use a low BTU fuel, My local Lowes just quoted
me a price of $15.98 per one gallon can of Denatured alcohol !
There is a whole ultra light camping crowd that carries Alcohol cook stoves, and this trend will continue as more and more areas and their hiking trails get closed
to open Fires!
