Every year, wildfires destroy important ecosystems as well as valuable properties around the world. The cost of the damage caused by wildfires is estimated in the tens of billions of dollars every year, and the method used to put out these fires are very rudimentary; as they rely mostly on firefighters physical strength. It is then important to find a more efficient way of putting out these fires.
I am proposing the manufacturing of huge flying vessels filled with water. If a wildfire is detected, these flying vessels would be called in and make a pass above the fire, putting out the fire while it is still in its infancy. Hundred of these flying vessels (which I call “Wildfires Killer”) would be built and they would be located in stations around the world where wildfires happens the most. Each station could contain up to 100 wildfires killers and once a fire is detected, a sufficient number of wildfires killers would fly in and make a pass over the fire, putting it out before it has done a lot of damage.
Each wildfires killer could be 50m long, 4m wide and 1.5 m high (see Figure 1). It is clear then that this wildfires killer could carry 300 tons of water. If we consider that a wildfires killer is attacking the front of the fire and it is spraying 30 cm of high pressure water on a band of the fire that is 4m wide, we can see that this wildfires killer will run out of water after it has covered an area of the fire that is 4m wide and 250m long. 10 wildfires killers would then cover an area that is 4m wide and 2.5 km long and 100 wildfires killers would cover an area of the fire that is 4m wide and 25 km long; always spraying 30 cm of high pressure water on each point of the fire.
No matter how big is the fire, no matter how remote is the area where the fire is located, enough wildfires killers would be called in and put out the fire in a matter of hours, while the fire is still in its infancy. Each wildfires killer could carry a lot of fuel, enabling it to travel thousands of miles without refueling.
The key to manufacturing these wildfires killers would be to design powerful engines, engines that can supply enough power to a rotor so that the rotor can be able to lift more than 60 tons. In the case of the wildfires killer of figure 1, this means that the five rotors should be able to lift more than 300 tons combined. This challenge has been overcome already as currently the most powerful helicopter (the Mil Mi-26) has a maximum takeoff weight of around 56 tons.
With these wildfires killers available, the problem of wildfires would be terminated and large wildfires like the ones that devastated California and Australia very recently would be no more.
