Virginia Polytechnic Institute and State University researchers found a way to use discarded corn husks and stalks to make cheap hydrogen fuel . Used efficient method to convert 60 % of plant sugars into 'green ' fuel . It 's previously only been possible to convert 100 % of sugars into hydrogen . Breakthrough could see motorists filling up at roadside bioreactors .
