Oiling the wheels of change
Sven Johnston’s reluctance to burn fossil fuels saw him convert his Nissan Safari to run on used vegetable oil.
He imported a conversion kit from America in 2004, which has enabled him to keep his car going on recycled oil.
Johnston says this alternative fuel minimises the impact he’s having on the planet.
Over the years, he’s converted a total of 14 vehicles, including two for his parents, who have nowmoved to an EV. The conversion to used vegetable oil suits older engines best.
Sven and his wife Sarah also teach natural building and straw build construction and have built several homes around the Geraldine area.
His advice: ‘‘Re-use – we can make great things out of other people’s discarded items.’’
Johnston says the use of straw, clay and sand is the basis of a sound and environmentally friendly house.
