You hear that whooshing sound? That's the sound of apartment dwellers all over the country pumping their fists in the air. Brasa's portable, ventless fireplaces run on denatured alcohol, otherwise known as bioethanol. No vents or installation are required, and the flame is regulated and can be controlled or extinguished at any time. There are 7 styles available, but my favorite was the one you see above: a stainless steel slim burner insert with a ceramic surround.
