Abstract: A water-based cooking apparatus onboard a vehicle includes a cooking bay and a controller. The cooking bay can be sealed with a lid so that water does not escape the cooking bay when the vehicle is in motion. The controller receives, from a computing device onboard the vehicle, cooking instructions including commands operable to perform one or more of filling the cooking bay with water, setting a temperature for the cooking bay, and adjusting a salinity of water in the cooking bay. The computing device can display cooking instructions on a display and can send status reports to a remote command center.
