Gentlemen, this thread is beginning to sound like so many alky stove threads, i.e. ever lighter stoves with no thought to FUEL EFFICIENCY.
** I still contend that my TD Sidewinder stove made for a small aluminum 3 cup pot is the most fuel efficient ESBIT stove available.
** With the Brian Green modified Gram Cracker tablet holder to hold in and utilize the burning tablet's liquid you will get even better performance.
** A narrow Fosters can is not as fuel efficient as my wide 3 cup aluminum pot. That's just physics, not opinion.
My Caldera Cone setup gets a 33%+ efficiency increase over my best previous ESBIT stove. And believe me, I've tinkered with ESBIT stoves for a few decades.
So it ain't all in the stove weight. It's in the amount of fuel carried as well.
OK, end of rant.
