SUNFLOWER POWER

If you were passed by a BL 1.5 or 2‐litre car on the roads of Britain's Midands recently, you could have unknowingly witnessed the beginnings of a new epoch in transport: flower power with a vengeance. For the overtaking car chugging effortlessly by in the other lane might well have been a test diesel‐type model running on liquid flower power — sunflower oil. Its engine, run entirely on ordinary sunflower oil as used by thousands of housewives in their kitchens, is claimed to do up to 75 miles per gallon.
