Selim says jojoba is worth pursuing as an alternative fuel because it contains less carbon than fuels like diesel, which means lower emissions of carbon monoxide, carbon dioxide and soot. And unlike diesel, jojoba oil contains no sulphur oxides, but the cylinders will be spared exposure to corrosive sulphuric acid, so the engine will last longer. Jojoba also has a higher ‘flashpoint’ than diesel, meaning it is less likely to explode while being stored or transported.
