  1. Question

    Can biofuel be used in space vehicles/ rockets etc.?

    Perhaps biofuels could be used. Many different chemicals have been used in liquid-fuel rockets, and kerosene (paraffin) is one of the common rocket fuels. While kerosene is derived from petroleum, similar materials could be made from so-called biofuels. David Morrison
