This fireplace of boomerang shaped is the EcoSmart Zeta, which, properly enough, comes from Australia. It is designed by John Dimopoulos, Geoform director, design and the firm of architects in Sydney and is a fireplace free of combustion that is fueled by denatured ethanol. Unlike the more traditional fireplaces, the EcoSmart Zeta requires hardly any maintenance and burn cleanly using a renewable modern energy source.
