Robotic Fish Detect Ocean Pollution
Built at a cost of $30,000 each, these robotic fish are designed to "head out into the open water, take in data about water pollutants, return to a charging station about every 8 hours and while charging, submit data about water quality." Video after the break.
The issues with this first batch of fish is pretty clear - they're way too expensive to be made in numbers big enough to be very helpful; their charge lasts just 8 hours so they aren't able to have a very large range away from their charging stations.[via Geekologie]
