Are there any fans of alcohol cooking systems out there?

I haven't found many discussions about it. I tested one for a night, but the slightest breath of wind would put it out despite using a windscreen, and it took almost 10 minutes and 25/30 ml of fuel to boil half a liter of water, even with temperatures between 10 and 15 degrees Celsius.

It seems really inefficient to me. Any opinions in favor?
