Alternative Propulsion
In the effort to develop an aviation biofuel, Air New Zealand and Boeing researched the jatropha plant to see if it was a viable green alternative to conventional fuel. A two-hour test flight using a 50-50 mixture of the new biofuel with Jet A-1 in the number one position Rolls Royce RB-211 engine of 747-400 ZK-NBS, was completed on 30 December 2008. The engine was then removed to be scrutinised and studied to identify any differences between the Jatropha blend and regular Jet A1. No effects to performances were found. The use of jatropha has been identified as a possible future fuel but large tracts of low quality land needed to grow the plant would have to be found without impeding other agricultural uses. Air New Zealand took the opportunity to retire ZK-NBS due to the economic global slowdown in 2009. It was then flown to the USA and broken up for reusable parts.

Famous quotes containing the word alternative:
“It is a secret from nobody that the famous random event is most likely to arise from those parts of the world where the old adage “There is no alternative to victory” retains a high degree of plausibility.”
