This aquatic drones can be used to study the ocean. It is a Saildrone that is able to capture precise data on salinity, temperature and count the population of fish.
The drone’s carbon fiber sail was designed to imitate an aircraft wing, so efficiently generates thrust from air flow. (Images via CSIRO)
It costs $2,500 a day to rent a Saildrone. The drones are also controlled via satellite and feature solar panels. In the future, this Saildrone might police illegal fishing and investigate global warming, the usages can be applied in other wider aquatic fields.
