I wish we could harnass that underwater technology so that we humans could finally explore the biggest mystery of our own planet. The depths...
There has got to be a way to reduce friction underwater and achieve better speed and depths. At the rate we are going it would take a Thousand years to map and cover all the deep water in the world, salt and fresh.
* NOTE - that's my own exaggeration of time but it seems like progress there is slow and at the low end of dollars going into it.
Just my 2cents
Also heard some chatter about oceanic mapping. The idea involves hundreds of small robotic submarines being released in all the World's oceans. They would be programmed with search parameters and conduct detailed grid surveys of all the oceans using radar etc. The data would be communicated back via satellite. One of the problems was power to keep them going. There was some talk about nuclear power, but that would freak out the environmentalists knowing hundreds of reactor are swimming about on their own.
I believe it was one of the oil-giants that were toying with the idea.
