It looks like an expensive "toilet paper heater". You know, those ones where you take an empty tin can, put a roll of toilet paper inside (with the core removed), and with an inch or so of space between the top of the can and the roll. Then you pour alcohol on it and light.

Also, I believe that even methanol does not combust completely and thus would produce carbon monoxide, making it unsafe for enclosed areas. I have not looked into it but perhaps there is a dose issue here.
