Description given on Youtube:
In the wake of steeply-climbing fossil fuel prices, interest in bio-fuels has grown world wide. until recently the leading bio-fuel feed stocks were sugarcane and maize. But sugarcane requires a year to grow and large amount of irrigation water and maize also requires a fair amount of water. Sweet sorghum is similar to grain sorghum but with sugar-rich stalks and the ability to use water efficiently. sweet sorghum has shot into prominence because of its competitiveness as a major feed stock for bio-ethanol production.
The present video is based on the process and use of Sweet sorghum as an important Bio-ethanol crop.
