I like your thinking. Minority interest I thought would be in the 1-5% range. Branson would want more than 1-5%. From a name dropping standpoint, I am thinking Bill Gates or Ted Turner. We already know that the guy from Sun ie McNealy is in on this somehow with Celunol.
Gates is on a buying spree so expect some of his money to come this way.
If you're going to make a wishlist of investor names, how about you include some even bigger ones like Exxon, Chevron, BP, Shell, DuPont? $30 million is hardly anything to those companies & it would make a wonderful PR for them to be able to say they are "leading the world" in cellulosic biofuels. Not that any of this is likely to happen, but it kind of makes you want to load up on shares just in case.
