As useful as I think the plan is, I have to wonder if it's practical.
British scientists have developed some sophisticated, robotic fish that they plan to release in waters off northern Spain. Their purpose is to detect leaks from underwater pipelines before they become calamitous.
The realistic looking robots make swimming movements and guide themselves. They run on 8-hour batteries and return to a recharger hub. I can almost picture these realistic-looking, robotic fish all gathered around some device, fluttering their fins as they get juiced up.
My big question is how a $29,000 robotic fish will protect itself from predators who generally eat smaller prey in big gulps. Picture the poor big fish who has swallowed one or more of these robots when it comes time for them to resurface to relay data to a control center. . . talk about stomach butterflies!
