Ethanol fireplace burner without smell

The bioethanol burner is designed to be placed inside an home fireplace. Bioethanol (beet sugar alcohol) is a 100% natural, and finely distilled. While burning, it does not smell or generates smoke, only water vapour and carbon dioxide, the equivalent of 3 candles.
The leads from the chimney are not necessary, and can be closed. In an open fireplace, 2/3 of the heat goes away through the leads. By closing the duct, the heating capacity is multiplied by 3.
