When I first saw the Vauni Globe, I thought, "What an uncomfortable place to sit!" And, indeed, it would be supremely uncomfortable to be incinerated.
The Vauni Globe fireplace can be turned 360 degrees so that you can direct its warmth anywhere. It's an ethanol-based, chimney-free system that's also freestanding so you can move it wherever you want. The lining is actually smooth concrete, and there shouldn't be any cleanup after you put out the fire as there's no wood burned, only fuel.
The Vauni Globe won't keep your house heated for cheap, though, as it costs over $6,000.
