are you even reading the thread, stuart? ( I'll let you in on a secret, stuart- I DO know about gas stoves of all kinds - MSR has GIVEN me multiple stoves including a PocketRocket. I still would not bring a pocket rocket bike touring! )

I'm sorry but thulsadoom was retelling his use of the large, heavy green propanes common at cheap mega store outdoor sections. there are single burners that attach to the tops of these.

I wouldn't be referring to them except as a mistake for bike touring but YMMV.

for all the dis stuart is giving alcohol stoves, alcohol stoves are VERY COMMON overseas, common with bike tourers and the ultralite backpacking crowd. Anyone grousing about BTU values of fuel is really overthinking a very simple, reliable stove system.
alcohol stoves burn alcohol, which you can buy at a drugstore, a gas station, a hardware store, a grocery store, just about anyplace. You can burn everclear or 151 rum, paint thinner-check the label!-, rubbing alcohol and HEET.
