Anyone own one of these or seen one? I'm not familiar with the way the wood can burn like that. What are some problems in tending what seems such a delicate fire?

I've been very intrigued with this since discovering it. I imagine myself some day living in a small place in the woods and this looks very preferable to a simple wood stove for heating purposes. This thing looks like it could radiate some nice heat. I'd most likely live in new england btw to give you a sense of my heating needs.

What do you think about these /out?
