No. What it means is that according to everything I know about biological systems, the laws of physics, the process of pumping, transporting, and cracking oil, etc., taken in conjunction with the facts presented in this article about processing algae, I have every reason to think that this technology is a viable alternative to at least some of our energy needs.
I use language such as "suggests" as all scientists use such language--to mean that all available evidence supports my opinion, while acknowledging that contrary evidence could show up in the future. If there is opposing data, it is not out of reach--I or someone else would have found it or known about it already.
Do not mistake a scientist's acknowledgement that he or she could be wrong for uncertainty. We use language such as "suggests", "could", "possibly", etc., when we are, in fact, very, very certain.
