Advances in Aircraft Propulsion

Bio-fuel technologies, driven by the dual motivations of fossil fuel depletion and climate change imperatives, are progressing at a rapid pace. The technological feasibility of using bio-fuels in aircraft engines has already been demonstrated amply. It is only a matter of time before the cost of bio-fuels, which is around three to four times that of equivalent fossil fuels, is brought down by technological innovations to lower than that of fossil fuel. Changes to existing internal combustion jet engines to switch over to bio-fuel would be minimal and easily achievable.
