I like this kind of thinking...

"A few months back the idea of using kudzu for biofuel was 
receiving a good deal of attention, with one entrepreneur 
attempting to market ???kudzunol???. Now another invasive species 
in the US Northwest is being investigated for use as a biofuel: 
Eurasian Milfoil. The water plant has been infesting rivers and 
lakes for three decades now, and a good deal of money is spent 
removing it every year. What if that plant could be put to better 
use? That???s the question that was asked by a couple from 
northeast Washington."
