Boeing and Air New Zealand have announced that they will carry out the first flight test of "second generation" sustainable biofuel in an airliner on 3 December. The planned test will be carried out using an Air New Zealand Boeing 747 flying from Auckland. During the flight, one of the jumbo's four Rolls-Royce engines will run partly on biofuel. The juice to be used in next month's Antipodean test will be made from jatropha nuts. The hardy jatropha is said by its advocates to be capable of growing usefully in arid regions unsuitable for food crops, and in this case - according to Boeing - the nuts have been "sourced from nonarable lands in India and Southeastern Africa (Malawi, Mozambique and Tanzania)". Other ideas for gen-2.0 jetfuel biomass include algae farmed on water, various kinds of fungus, even domestic garbage. Read more here.
