This is cool but the autonomy problem remains. Most (aerial) drones can't fly more than 15 minutes. I am curious about the power used underwater to move it.

- jessriedel 11y agoThe ~15 minute lifetime comes from needing to continuously tread air to stay aloft. (You can use up the battery faster by going fast, but there is a max time to just hover.) In contrast, a water-density vehicle could float around and leisurely collect data for almost unlimited amounts of time so long as it doesn't need to get anywhere quickly. (Currents will complicate this.)
