But, just like all other feedstocks, the Rice husks or whatever else that is cheap today will become a commodity and will be expensive as the demand grows for it. So realistically, research should be focused on growing something that grows faster than a typical plant (whether it is rice or wheat or a tree) than we will stand a chance to curb Green House Gases. That's why people are so interested in growing Algae for fuel (which can double in it's mass every few hours).
i\'ve also developed a product using biomass like maize straw and maize cobs and other agri wastes by improving its nutritional value and digestibility so as to be used for naomadic sheep rearers in tamilnadu.
