There's just nothing like a roaring fire in the middle of winter to warm your bones. Unfortunately, for those of us living in big cities fireplaces are rarely a viable option. Personally, I've found the flaming trash can to be a decent replacement, but if you don't happen to live in a hobo-cluttered alleyway that might not work as well for you.
The Tabletop GlassFire Smokeless Fireplace uses efficient biofuel to create a blazing fire with no smoke, so you can use it indoors with no chimney. It looks pretty small, so fire-in-a-jar might be a more apt description than fireplace, but your mileage may vary. It's all yours for a mere $550.
