  • Desert shrub yields new fuel alternative

An oil frequently used in cosmetics and shampoos may prove a viable alternative to diesel fuel for cars.

In this article, Ian Sample reports that scientists in the United Arab Emirates and in Egypt have found that engines powered with jojoba oil are less polluting, run more quietly and for longer, and perform as well as diesels.

Engineers think the oil, which is extracted from nuts produced by a desert shrub, 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.
