Jacob Lalinsky's Crows Nest Anti-Pirate UAV is one concept that needs to be created now. This UAV will keep ships and crews safe, which is necessary in today's pirate-plagued waters.
Pirates have made a resurgence while counter-piracy tactics have not. The Crows Nest Anti-Pirate UAV would keep ships safe by circling around and setting off an alarm at the sight of approaching vessels. The UAV also has a video feed, so you'll know who and how many are coming. Fighting fire with fire can be dangerous, especially against pirates. Sometimes a head start on running away isn't the worst thing to have.
