Not familiar with this puppy, but in spending a few minutes researching, it appears that the business model is flawed.
According to the link below, ethanol has historically sold for a higher price than unleaded gasoline. The government subsidies (on which the business model is based), drops the price below gasoline. The problem with that however, is that ethanol contains about two-thirds of the heat energy of gasoline. So on at BTU basis, ethanol is still more expensive.
Alternative energy is fine, but at what cost? If I'm the CEO, I would change the model. If he has a track record of turnarounds, you may have a shot. Creditors are in line though (followed by a likely class action) so the turnaround would take years.
Henning seems like a smart guy, but it appears he is close to 70, and formerly retired. He is likely just a bridge to clear the creditor issues, and I'll guess he bails after that.
