It is a liquid so safety might be a concern. The MSDS mentions that while burning there is a risk of producing both CO and CO2. The MSDS for Sterno mentions no such risk. Still, with adequate ventilation that should be ok.
Could be useful for someone that needs more burn time due to space restrictions. I think that for my car kits I'll stick with the cans of gelled fuel and just pack more of 'em.
