Good memory, Rob! Yes, this does work, and in the future this will really give marine biologists a weapon to keep track of a number of sea creatures, sharks, of course, among them. But imagine the possibilities for tracking other types of fish and observing migration paths, depletion of fish in overfished areas and other patterns of behavior. Long-term these types of robots could prove to be valuable ecological and even economical tools. There also could be other applications for a wireless network in the sea.
That is funny, naperlou, but seriously, the implications of turning these tags into a network is a great idea. If the connections between enough sea creatures were initiated, a real-time 3D view of the enviromment and creature interaction could be invaluable for understanding the interrelationships of sea dwelling creatures, and their migration patterns. This could also give early warning to adverse environmental conditions.
Chuck, as you probably remember, Elizabeth did a story about great white tracking in the Pacific off San Francisco. If it works, it could be helpful on the East Coast. That is, if they could tag every great white.
Ann, if this is like a social network for sharks, the next step is letting them communicate with each other. With all the advances in robotics that should be something that is being researched. Then, Facebook could sell ads to them.
Ann, such real time tracing technologies will help to identify the moving pattern of shark. Moreover I think a small modification in the system may help to extend the study to other underwater specious too. but am not clear how long (range) the signals can be transmitted through under water, which can disintegrate on long distance under the acoustics conditions.
Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
Norway-based additive manufacturing company Norsk Titanium is building what it says is the first industrial-scale 3D printing plant in the world for making aerospace-grade metal components. The New York state plant will produce 400 metric tons each year of aerospace-grade, structural titanium parts.
