Jojoba (simmondsia chinensis)
Jojoba Oil (pronounced "ho-HO-bah"), is a desert shrub that can reach up to 4.5 metres high and typically lives more than 150 years, producing nuts that yield half their volume in oil.
"Engineers think the oil has potential as a motor fuel because it releases a lot of energy when it burns and is chemically stable at the high temperatures and pressures in a working engine.
To test jojoba in engines, Mohamed Selim and his colleagues at the United Arab Emirates University in Al-Ain and at the Helwan University in Cairo, connected an array of sensors to a diesel engine and monitored its performance while burning regular diesel fuel. They then ran the engine on a fuel called jojoba methyl ester, which they made simply by adding a dash of methanol and a catalyst to raw jojoba oil. 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."
