I would think that this is info IR should have been ready and waiting to share We have proven time and time again that Jan is unreliable. Carl however is more forthcoming with his answers and explanations and actually the best source for info is our own DD.
You are right you cant supply 20-30 thousand acres with 279, but they have already stated here: http://www.viaspacegreenenergy.com/giant-king-grass.php that you can use 279 acres to supply seedlings for 10,000 and well if they used that 10,000 as well for seedlings....with exponential growth in short time 20-30 thousand would be NO PROBLEMO.
I think I'm going to send Carl me resume. They need my help BAD - There is a job opening at VGE, if you meet the qualifications. Are you a farmer or a builder today? JK
