Really promising tech, and what looks like a unique approach to driving robots on (and in) different environments, such as water, sand and snow.

But I was really disappointed by the reference to 'stealth capabilities'. They're sponsored by Naval Research, so I'm sure military uses will come first - ahead of environmental use-cases. This is a shame, because it does look to have been developed to interact with the environment with a very light touch.

Their website does mention divers and recreational use (stick a board on top, and you'd have an awesome play-thing), but I wonder how far down the pecking order those applications will be.

Very nice hunt...I just hope the project heads in the right direction.
