Soya jet fuel is ready to take off

It is used for cooking, breast implants and aromatherapy. Now soya oil could take us on holiday.
Biochemists believe the oil could be used as replacement for jet fuel. Scientists have experimented in the past with blends of aircraft fuel - known as Jet A - and vegetable oil.
But while aviation fuel stays liquid down to -40°C, vegetable oils freeze at around 0°C. Now biochemists at Purdue University in Indiana have developed a blend of 40 per cent soya oil and 60 per cent Jet A that freezes at - 40°C.
If the fuel is a success, it could have a big impact on air travel - and on the planet, New Scientist reports. There is growing concern that air travel produces the gases that cause global warming.
Some experts believe that, by 2050, air travel could account for nearly 75 per cent of Britain's greenhouse gas emissions.
