Weeds Are The Fuel Of The Future
Kudzu is an extremely fast growing plant, usually considered a weed that can grow up two two inches a day. A native plant of China, it was first introduced to the USA in 1876. It was planted extensively in the southern United States to prevent soil erosion. Fast forward to today, and Kudzu is everywhere in the South, growing out of control and messing up the local ecosystems.
The good news is that the Kudzu plant is a great raw material to make ethanol. The roots are the size of sweet potatoes and contain all the right elements to produce the (currently) corn crop hogging fuel.
