Comment Coral Pipes (Score 1) 27
Can't find anything on the InterWebs, but I remember hearing a news story in the '80's about a company in FL that was using a low-voltage electric charge on a chicken-wire dorm to attract corals. They were going to use the process to make permeable drainage pipes, which would be useful in FL and other places where groundwater accumulation can lead to things like sinkholes or swamp-like conditions during flooding.
IIRC, they were saying that in the warm water off southern Florida, they could create one section of pipe in about a month. No idea what the impact was on near-by coral populations of course.
Since there's nothing about it online, I'm sure the whole thing went south, but it was a neat idea.
