Reinventing small scale steam - the next opportunity for 21st Century renewable power – electricity, mechanical power, heat, hot water, steam and distillation, 24 hours a day if necessary - all from local fuels.


The Uniflow Generator is a small scale, reciprocating steam engine for production of heat and power using the lowest grade woody and waste fuels. Presently designed for production of 5kW of electricity the Uniflow Generator is a 21st century steam engine with potential to provide power where ever a small diesel or petrol generator might otherwise be used – and in places where diesel and petrol are not available at all!

Small scale, reliable and robust steam engine generators have the potential to free off-grid households and communities from the need to purchase diesel or petroleum based fuels to generate power. This is particularly the case where a 'hybrid' renewable energy system, incorporating solar panels, or small scale wind turbines and a battery bank are already in place. Every one of these 'hybrid' systems generally also has a petrol or diesel generator integrated into the power supply to enable the battery bank to be conditioned and recharged. In many situations a Uniflow Generator could replace those fossil fuelled generators.

The Uniflow Generator can produce more than just electricity. This versatile energy production platform can also deliver hot water, rotary mechanical power, wet or dry steam, and distillation if required, all from low grade renewable fuels.

The Uniflow Generator is actually a combination of two notable and patented advances in steam and engine technology designed by famous Melbourne steam engine builder Ted Pritchard - a highly efficient small furnace and boiler, and the advanced single cylinder double-acting uniflow engine. Patents have been granted in Australia, the US and the Peoples Republic of China and in Europe on both inventions, and are progressing towards being granted in Japan, Brazil and India.

The company expects to complete the testing, design and engineering work required to prepare a commercial model of the Uniflow Generator for market during the coming year and has already fielded a number of enquiries from companies capable of being commercialisation partners in the UK, Europe, India, South America and South East Asia.

Models with outputs from as little as 2kWe and up to 20kWe are under consideration.


The patented engine of the S5000 has done for steam engines what IBM did for the computer, made it small and personal.
