Nice one barit1. Yes there are issues with corn prices and ethanol. What will become of cornflakes if the USA moves to ethanol for it's cars and light a/c?
Far better to wait for Branson's lot to produce synthetic ethanol (uses almost any waste so not crop dependant) or grow elephant grass or Jatropha which can actually improve food harvests whilst making bio diesel.
eg:
The Vanilla Jatropha project undertaken through the Kenya Small Project Facility provides an example of the sustainable development benefits that can result from a small-scale CDM project that has generated interest from buyers. Local farmers will cultivate jatropha trees whose seeds will be harvested for expelling oil that will be used for production of jatropha oil. The raw jatropha oil will go through a transesterification process to produce bio-diesel and glycerol. The jatropha oil will replace the use of kerosene for lighting and cooking, and the bio-diesel will provide an alternative fuel for combustion engines such as generator sets. By-products include seed cakes that can be used as organic manure and glycerol that can be used to produce soap. Benefits to local families and farmers include both financial savings and income-generating opportunities, improved health benefits from using a clean fuel, and the additional benefit of organic fertilizer and glycerol production.
