A threat to boating. Or possibly its saviour.

A very interesting story in the Sandusky Register here. The major question on everyone's lips is, of course, where the heck is Sandusky, but that's not important. The big question is whether making fuel from algae is a good thing.
Apparently, algae can be brewed into fuel just like maize or palm oil, but with the great advantage that it doesn't displace crops for food.
I am in two minds about this. If algae are removed swiftly and efficiently from the waters I personally row in to feed fuel production, that is obviously good, but if they decide to farm algae in my favourite rowing waters, this would not be so good. Another eco-conundrum.
