The fuel ethanol still is a continuous distiller capable of producing 90-95% industrial grade ethanol continuously, suitable for fuel use. The 3KW fuel ethanol still is a small machine that produces 1.5L of fuel ethanol per hour. The machine can work automatically and can be attached to any size fermenting vessel or low spirit percentage source to produce high percentage fuel ethanol continuously. This version is no longer available for sale but is described in the fuel ethanol still construction manual. The still was tested with 1.5KW and 3KW heating elements. The production speed doubled with the 3KW element application, reaching up to 2.5L per hour at 95%. The still showed very stable performance with the 3KW element, and there are plans to try a 4KW heating element.

The 4.5KW fuel ethanol still represents the final version of the continuous fuel ethanol distiller. It is capable of producing 2-3L of fuel ethanol per hour with an alcohol strength of 95%. The amount of ethanol that can be produced by this unit is limited only by the feedstock supply. This means that the still can work 24/7, continuously producing fuel ethanol for your needs, especially if you have access to low-cost raw materials such as molasses and different kinds of sugars or by-products of sugar production.

In contrast to widely advertised and expensive micro fuelers that use expensive molecular membranes, the fuel ethanol still can be built by a hobbyist familiar with TIG welding. Access to a local scrap metal yard and plumbing suppliers is sufficient, and even buying a small TIG welding machine to build the still will be much cheaper than buying a fueler. The older version of the still shown in photos and videos on this page was built from off-cuts and stainless scrap from my business, demonstrating that it can be done without spending extra money.

Plans and more detailed information regarding the construction of this still are available on the DATA DVD or can be downloaded from http://www.doubloonbay.net/index.php. The materials include many pictures of stills constructed in a simple garage environment using simple tools and methods. The construction manual also includes a detailed video of still handling and exploitation.

This still is versatile; the detachable fractional column can be combined with the packed extension and used separately with a batch boiler for fractional distillation of food-grade ethanol. The main stripping column is a high-speed continuous stripping still that can work independently from the rest of the fuel still construction. It can be used for continuous production of raw spirit for further fractional distillation and purification with a fractional still, ultimately leading to food-grade ethanol production.
