I built and tested an alcohol stove. It is a fancy feast type stove with a carbon felt wick. The stove is really lightweight, fairly easy to build and works fine for smaller cups and pots.
I was surprised how fast it brought the water to a boil.
Considering that I have only two Trangia burners, three gas burners and a MSR multifuel stove that was a totally justified and desperately needed expansion of my gear and not playing around with a new toy.
GF had no objections to me testing it in the kitchen.
