sea gliders

I agree, I think it's a nice idea, I would love to travel in a vehicle like that but it wouldn't be fun running into a wave or a breaching whale. At the speeds they're talking about, you won't have a lot of time to avoid something. I think it would be great for calm waters without potential obstacles, I just don't think the Hawaiian islands are suitable. Who knows, though, maybe they have some technological breakthrough that makes it safe.
