Drone warships may soon be sailing under their own power using sediment sucked from the sea floor. How does it work? Well, the batteries create current by using the natural fuel sources in the water and from sea bottom dwelling animalcules.

Office of Naval Research just did a patent on making energy with a combination of seawater and organic material at the bottom of the ocean. If this can work in large quantities, you can see an unmanned vehicle out there simply burrowing down into the bottom of the ocean trying to recharge. … It’s unmanned systems [like that] that offer tremendous versatility and tremendous reach.

These fuel cells convert naturally occurring fuels and oxidants in the marine environment into electricity making them a viable power source for long-term operation of autonomous underwater unmanned vehicles, in-water sensors, and devices used for surveillance and monitoring the ocean environment.

Thus far they’re using the technique to power small buoys but with enough research and big enouch batteries you could potentially sail the ocean blue with the slush at the bottom of the sea.
