Re: PowerDolphin For some people and groups, a novelty.
But for those of us with even some sea time, and who admire a designers appreciation for natures designs and seeing if incorporating what already works will work - to see this is great.
It simply looks to me like a well designed water drone. So many water tasks have to be done 24/7, 365 in our world, that the applications noted in the vid are only some of how this is useful.
If the specs on energy use and other details are good, this idea of general use water drones should see success.
