Researchers have created a silicone submarinal robot that gets about by mimicking the motion of a jellyfish. The robot is powered by heat-producing reactions catalyzed by its surface, and using hydrogen and oxygen present in the water as fuel. It's claimed that that the Robojelly, (named by its Virginia Tech creators), could run indefinitely, drawing energy from the water in which it swims. also known as Cyro.

It may someday be used for undersea suvelillance.
