The Truth About Drones
This talk about drones, making deliveries, is absurd. Below is our opinion as to why we think these claims are purely propaganda. We are sure that drone delivery talks - with the current state of the union - are nothing more than a marketing trick, at best. There are serious impediments keeping these hopes grounded. Below we'll discuss the top three: 1) Noise, 2) Range, 3) Navigation.
The Home Delivery Falacy
NO, we're probably not going to see drones buzzing around our skies bringing Amazon packages to our doorstep. There are many reason behind "the why not", but we'll give you the big ones. First, noise pollution. The propeller angle needed to generate lift is also an angle that generates noise...lots of noise. And so far, no one has invented the "silent propeller". Second, payload vs. drone weight. in order to transport your products, drones have to be larger than their cargo. Drones are small, so there are limits to what they could delivery. Finally there is the issue of battery life. Drone flight time is on the average 25 minutes. That means it needs to make a round trip within that time frame. A community member had other reasons why this wont work. You learn more about his comments here.
Noise Polution as a limiting factor
The helicopter has been around with us for decades. Yet, their use has been very specific and limited. The noise level generated by a single drone is substantial. And if you increase that by any multiple, you end up with a mind numbing buzz seen only in horror films. Its hard to imagine the FAA approving the commercial use of home deliveries using drones in any wide spread scenario. Drones are already making their rounds off shore and in agricultural settings. There may be a place for them in certain urban settings too. But these needs are not wide-spread. But unless someone can invent a silent propeller, drones will be grounded from making mass deliveries to your home. And then, there is a the navigation issue...
Lets imagine for a moment that we were able to overcome the noise pollution generated by drone propellers. Drones would almost certainly need to be "self-flown". drones would also need to be interconnected before they could be set out in large numbers. And drones would need to have their own fly zone layer above 400 ft to move around before dropping out of the sky for the delivery and pickup of your product. Drones are quickly getting smarter and they are becoming far more familiar with their surroundings. They can identify and avoid obstacles. But this technology needs to be improved and drones would need to speak to one another so that you they could fly in large numbers without crashing into one another and or into their surrounding.
