A different add-on is making headlines this week and we will leave it up to you to decide if it is useful or not. Meet the TF-19 Wasp, aka the Flamethrower drone.
Drones have a ton of versatility in them. You can mount different cameras onto them, you can add baskets under them for deliveries, and you can even add toy cannons that fire plastic balls. Drones are very versatile and can do a variety of jobs if given the right add-ons.
As the name implies, the Flamethrower drone is a standard drone armed with a fully functional flamethrower. It comes with its own fuel source on deck. This not only means the flamethrower can stream fire into its enemies continuously, it also means it is very portable. Having the ability to fly and reach tight places means, it can be a very effective pest control tool, especially against hornet nests and other agricultural pests.
The TF-19 Wasp can shoot a stream of steady fire at up to 25 feet, giving it a bit of range. It can also fly for a decent amount of time, although it will fly shorter than most drones as it has a payload to carry. The added weight of the flamethrower unit itself, as well as the 1-gallon fuel tank means that the drone you will use will work overtime carrying the entire rig.
Of course, with such a radical idea come setbacks. Controls would be a bit more difficult than operating a flamethrower manually. The high elevation environment also adds a ton of risk, and carrying fuel onboard exponentially multiplies it. Having a device that can shoot fire means it has a ton of risk for excess damage, and even accidental fires of the area. It can also damage more than its intended targets, leaving you with more worries than gain.
