While I have not been hobo-ing yet, when I do camp out and travel, I use a home made alcohol stove with 3 cans of coke, called the "keyhole stove" it got its own base with a wind block on the base. You fill it and put some alcohol on the bottom and light it, it will work when there is a breeze, and lights up quickly. I carry alcohol in a water bottle. ! squishable Gatorade bottle last 1 week.
The stove is small, fits inside a aluminum mug, which i bought for cheap. inside the mug also a aluminum foil windblock screen, a 3 leg stand made out of coat hangers and plastic syringe, lighter, scrub pad and lid made of large bean can. The entire cooking set fits inside itself ( except for fuel). it weights less than a cellphone. It doesnt work too well with a lot of breeze, takes longer to cook and less efficient.
For those who say you can't see the flame...you cant in broad daylight. But a shade of a bridge or your hand can make it visible. Also you can hold a twig see if it burns, or just look at the stove and watch for heat wave. You can totally see it at night.
Here is my stove:
Oh, and those who say you use Propane...are you talking about the green coleman canisters, or the small, aluminum canisters?
The big, heavy steel propane canisters are near indestructible, but heavy as fuck
The smaller aluminum come in tow types:
Isobutane ( a mix of 20% propane and 80% butane) found in wal-mart for coleman "hiking" mini stove. The propane propels the butane at low temperatures.
Butane: red MSR or gray cans found in outfiters, like Bass Pro shop, etc. 100% butane, same as your lighter. They dont work well when frozen or near freezing temps, you have to warm the can first.

Isobutane:
And Regular butane:
