There's been quite a bit of fuss over the use of airborne drones for just about everything, but these underwater drones are making just as big an impact. While arguably the biggest story for its airborne brethren is the de-polluting potential, this underwater variety will feature weather predicting ability.
There will 16 submarines that will be continually collecting information about the ocean and the currents to predict weather. The drones will travel about 35 kilometers daily and use depth and altitude sensors to find patterns in the weather.
The reason for using underwater drones is because the health of the oceans can be directly linked to the health of the planet. The weather can have a direct impact on the ocean, its pollutants and all manner of other factors.
