I think you are both right, but I think the main point is total cleanliness, most efficient and cost effective, least amount of waste and most environmentally friendly will win. Overall that is. Batteries are huge polluters when their lifespan is over not to mention the other things involved with creating electricity. The main point I have seen and read is there is not a way to produce enough fuel from algae in a cost effective manner that makes it feasable at this point in time (key point, at this point in time). Like the article said, it is about finding a technology that will be cost efficient to produce fuels from algae. That technology is being worked on and is being massaged, tested, adapted etc, to become more efficient. Seems to me it is only a matter of time until the most efficient and cost effective way to produce fuels is learned and perfected. Even once we think we have it perfected it will then be re-tested etc. until even more efficient. Batteries can only do so much, stay so green and go so far. All in my opinion!
