Hope the personality focus and negativity some unfortunately have can stop, and on-topic discussion and good will can prevail.

Regarding woodburning systems: I experimented with these quite a bit. They have their pros and cons. The cons can be largely overcome through better skills and practices.

IntenseAngler shows his DIY woodburners in action. Others also have videos at youtube.com on the topic.

However, once you learn a variety of improvised setups, and gain a little facility with these, they are quick and simple. And you don't need to carry them around.

These are both lighter and simpler than alcohol fuels and stove systems. And less bulky, easier to carry.
