What do you guys think about this? or has someone already covered this : http://www.physorg.com/news156681859.html
Okay I have one question it only has a 8 hour battery so if it goes out how will they retrieve it and what about predators in the ocean ?
yip, was just wondering the same thing...plus, someone mentioned that fisherman could catch it and also it could be eaten by other predators...doesn't seem to be very well thought out!!!
On the plus side - at least they are TRYING to find a way to monitor pollution levels. I'm not sure that this is the brightest way to do it though.
Have to agree with all that's been said. 8hrs isn't a very long time, but yeah I too am glad they're trying to monitor the pollution levels and atleast do something about it.
Indeed it will Johan! That's the wonderful thing about earth. We're a bunch of scavengers and the earth could wipe us out in a second if it wanted to.
