In posting that article, I was mainly interested in pointing out the extent of growing competition within the ethanol market and how there will be a race to meet demand. Judging from its latest success in Iowa, AENS is very well positioned to exploit that market and stand up to any competition which makes this a great investment, especially at the current PPS.
Beemer sees this as a "cottage industry" but within a few years, when supply and demand approach equilibrium, I would expect to see some price wars between competing cottages.
Of course, oil prices will fluctuate, but because oil production will be unable to increase fast enough to meet the demand, the trend will always be toward higher oil prices, good for the suppliers of ethanol. I'm not even considering the economics of peak oil.
