wouldn't an alcohol stove/burner be a good source of heat indoors? they are extremely easy to make and from what i've read, burning alcohol does not produce carbon monoxide. i use one for camping and i love it. if i remember correctly, DR had a link to a site that gave instructions on how to make an alcohol stove with a coffee can and a roll of toilet paper. i tried it and made one out of a coke can and it worked fine. i've also read you can use just about any small can packed with cotton balls. and the best part is that you can use regular rubbing alcohol or even vodka, scotch, etc. as a fuel source. can someone confirm that burning alcohol does not release carbon monoxide? just wanna make sure thats correct. thanks.
