‘Underwater → Sky’ drone flying

The Aerial Robotics Lab of Imperial College London, UK, has developed a prototype drone called AquaMAV that explodes gas and soars into the air from underwater.

In addition to electric power, this drone has a propulsion system using calcium carbide and water. Calcium carbide reacts with water to generate acetylene gas, so when it is sent to the combustion chamber along with air and water, when it is ignited, an explosion occurs at once, causing the drone to go out underwater.

Aquamarb can use this method to reach altitudes up to 26 m underwater. This method can be used to collect water samples and monitor water pollution in the event of natural disasters such as flooding. Related information can be found here .
