"Though this is a very interesting article, could you not find anything more reacent than September 2003? That is 6 years ago. There has been a lot of research done since then and everything has changed as far as energy costs."
That was part of my point, to show that what some people are calling new and novel, is not.
Other points were the hydrogen production with a trigger, which is also not new, according to that paper.
I forget the rest, IIRC, there about 6 good reasons for linking to that paper. Another was to simply point out the kind of data any real investor is going to want to see before putting big dollars into this, by showing what the data should look like. It also answered some of the questions, about light penetration through layers of algae growth, which was being discussed in the vertical versus horizontal tube discussions.
