In 1964, Pritchard formed Pritchard Steam Power Pty Ltd and began work on the design and construction of an auto engine. The resulting 33.5-kilowatt engine was fitted to a 1963 Ford Falcon that by 1968 was a daily sight in the inner city.
In 1972, he took his Falcon to California, where it was demonstrated to major car companies and investors. The trip resulted in a significant "option" payment from US investors and he was invited to testify before a US Senate committee into alternative fuels.
Two years later, Pritchard drove the Falcon from Melbourne to Canberra and back, taking Labor ministers of the day for a joy-ride around old Parliament House while he was there. That engine was tested at the Ford factory in Geelong and recorded tailpipe emissions that were not equalled until the Euro 2 low emissions standards were introduced in 1998.
Having demonstrated that a steam-driven car not only worked, but had real operating advantages over internal combustion engines, Pritchard moved on to design a production model of the power unit. It took longer, and cost more than expected, but finally an advanced Pritchard steam engine was built at the Bendigo Ordnance Factory, with backing from the federal and Victorian governments in 1978.
Technically referred to as an external combustion, advanced uniflow steam engine, the "V-Twin" as it was known, was set up on a dynamometer and started for first time by Sir Rupert Hamer without ever being test-fired before the then premier turned the key.
Despite years of overtures from car companies, Pritchard was never able to attract a major backer. He designed his own "green" car from the rubber to the chrome, built a prototype (he and the car are pictured together) and exhibited it in 1981 before finally being forced to pull the plug on Pritchard Steam Power due to lack of funding.
