I would love to get one of these. One of the things that I miss about living in the suburbs is being able to have a fireplace. Nothing like a blazing fire on cold nights to boost the cozy-factor. I have actually been frequenting a place in Brooklyn recently, almost solely for the fact that it has a giant fireplace (never mind the fact that I always come away smelling like camp fire).
Anyway, this model in modern design seems to be the solution. Designed by Holly & Martin, the portable fireplace runs on gel, and can be used indoor or outdoor.
