Waste Oil Burner for Off the Grid

I have been using a waste oil burner for a few years that works well. It is a Little Dragon design (patented)and uses compressed air and a venturi principal to atomize the warmed oil into a burn tube. I bounce the flame off of an old brake drum that turns cherry red… really cooks when it gets going. However… I am moving to an “off grid” location and would like to setup using a DC […]

Stirling Engine to Power Air Compressor/Pump for Babington

I am in the middle of building my first Babington, and am interested in the amount of electricity that the compressor/oil pump will consume. I have also been reading a little on Stirling engines and wondered whether there was a cheapish one that would be powerful enough to drive the pump & compressor directly. Does anyone know anything about Stirling engines? I had heard of them but didn’t know how one worked until I looked […]

Wood Chips as a Power Source

Over the last few months I have been working on a burner for the clean burning of woodchips – so that they may be used as a heat source for a small Stirling engine generator rated at about 500W. My first burner was built using a 2lb coffee tin, fitted with an air nozzle powered from a PC cooling fan. The burner is 3/4 filled with woodchips and lit with some newspaper. The fan soon […]

Lack of Stirling Engines

Stirling engines have been around since 1816, but achieved widespread commercial success between about 1880 and 1920. At that time they were commonly known as hot air engines and available in 4″, 6″ 8″ and 10″ bores, with power outputs generally less that 1hp. Manufacturers including Rider, Ericsson and Robinson were prevailent about a century ago. A hot air engine does not possess the regenerator, which characterises the true Stirling engine. During that time they […]

Solid Fuel Wood-Gas Canisters

Fuel handling for a modern wood gas car is going to be the major issue for public acceptability. Ideally the fuel should require little or no human handling and the ash and clinker should be disposed of in a user friendly manner. Here is one idea which could help to implement such a scheme. Imagine a 5 gallon drum made from cardboard , with steel endcaps, full of compressed sawdust. Down the centre of the […]

Free Breeze (Stirling) Fan & Small Stirlings

I noticed from a recent survey of the keywords used to access my site, that 45% of you were typing in “wood stove Stirling fan” . So, in order to give you what you want, here is the homepage of the Canadian built Free Breeze Fan. The idea is simple – a low tech, Stirling engine, optimized for the sort of temperatures that would be found on the hot plate of a stove (250 to […]

What Working Fluid is Best

I have been watching with interest the discussion of Freon, ether, etc. as a working fluid in some type of heat engine. I have an idea to build a system that would use heated water at 180deg F. We could use ambient outside temp, which in this area is never above 100deg. and is rarely above 90, to condense back to a liquid. Does anyone have a suggestion for that range? I don’t have a […]

Viebach Stirling Engine – Background

Here are some background notes about the Viebach ST05G Stirling Engine, the original prototype and the construction. Basically a DIY Stiling of about 500W shaft output based on aluminium casting set.  Power output improvements to 1kW should be possible. This engine has been built by amateurs – mostly in Germany, and I have seen it run on wood, charcoal, wood pellets, natural gas, propane. A ready built engine can be bought for $4000, or home built […]
