Meet Cyro, the Virginia Tech College of Engineering underwater life-like jellyfish drone in development for US Navy surveillance.  The jellyfish drone isn’t designed as an extremely efficient method of hydrodynamic propulsion, but rather it is meant for ‘natural stealth advantage’ allowing subversive access otherwise unattainable by traditional engineering.  This current version of the Cyro can last three to four hours in motion with its rechargeable nickel metal hydride battery.
