Have you seen this stove? It’s called the BioLite camp stove. Use it to heat your water and charge your phone, all from the same fuel (a few dry sticks). Pretty neat.
Thanks for the tip, Richard!
Update 10/28/2013: Here’s a link to a good Cool Tools review of this stove by someone that sounds like they’ve spent some time and assessing its pros and cons. I recommend reading it, if you’re interested in this stove.
