Thing is, algae needs water and not land. so not sure the comment even makes sense.

I'm well aware that algae needs water... the point was that there isn't enough surface area of the water (because it needs light, too, right?!) to grow enough algae to completely offset oil production for diesel or gasoline.
Yes, that includes using all available bodies of water in the US, and US-accessible bodies. Trouble is, without a controlled growth method, there are other ecological side-effects to look after as well...
Sure, we could cover the entire ocean in algal growth, but then what happens to the creatures beneath the surface that need light?
The towers that are being researched are just water tubes that flow through a filter which filters algae that have grown to a certain size, and only when flow through the filter is opened. In this way, algae can be grown/sustained in water filled tubes that extend hundreds of feet into the air, rather than spreading that same amount of algae over hundreds of square feet of water.
Jeez, way to over-analyze a comment.
