What makes this different from other kinds of camp stoves is that it has a "power module" that uses heat from the fire to generate electricity to power a fan. This fan blows air into the fire, making it burn hotter and more efficiently than it would otherwise. And as an added bonus, since it generates more power than it needs, it also has a USB port that you can use to charge small electronic devices when the fire is burning.
Interestingly, they also make a large model. Their Home Stove is targeted at people who routinely cook over open fires (like in many third-world countries.) Using a similar design to the Camp Stove, the Home Stove consumes less wood, emits less smoke and gives off less carbon monoxide than an open fire. And it also has a USB port to power small devices.
I realize that I'm not the target audience for these products, as a person who lives in a house with a modern kitchen and never goes camping, but I can appreciate great tech when I see it, and this is pretty awesome.
