Airbus has joined Honeywell and JetBlue Airways in an effort to reduce pollution and dependence on oil. They are trying to develop a biofuel that could be used by 2030. The companies think they can almost cover one third of the world's airplane fuel need. A plan to create a biofuel that won’t affect food resources is the proposal. Algae is a possible alternative because it absorbs carbon dioxide, and it will not affect food production. However, algae and other vegetation are still just experiments, and algae is expensive to develop. Airbus recently had the first alternative fuel flight. It ran on 60 percent kerosene and 40 percent gas to liquids (GTL) fuel in one engine. It did not cut carbon emissions, but it was free of sulphur emissions. Alternative fuel was able to work properly in Airbus' aeroplane engine, so alternative fuels should not require new aeroplane engines. This flight and the company's long term efforts are considered big strides towards environmentally friendly aeroplanes.

Famous quotes containing the word record:
“He will not idly dance at his work who has wood to cut and cord before nightfall in the short days of winter; but every stroke will be husbanded, and ring soberly through the wood; and so will the strokes of that scholars pen, which at evening record the story of the day, ring soberly, yet cheerily, on the ear of the reader, long after the echoes of his axe have died away.”
—Henry David Thoreau (18171862)
