If you have ever considered purchasing a drone or directly have one in your possession, you will surely know that one of the great limitations that it presents lies precisely in its autonomy, usually too small. Imagine if, as is the case, some team of researchers managed to eliminate the battery precisely from the equation while getting the drone to fly forever. This is precisely what they claim to have achieved in Imperial College London.
As those responsible for this project comment, the truth is that there is no other trick in its creation than to acquire a standard commercial drone, eliminate its battery and make it fly without the need for it. Even so, we still have many limitations to get this technology to reach the market since the drone is powered by electricity without cables, that is, moves thanks to magnetic induction. The result of this is that, it is true that the drone flies without a battery but it only manages to lift off the ground a few centimeters.
Imperial College London shows us a drone capable of flying forever without the need for batteries.
Contrary to what you can imagine, magnetic induction is very common today. Without going any further, we use this technology to charge our smartphone or tablet without cables and, as you surely know, for this to happen we find another of the limitations, in turn, of this technology and that is that the receiving object must be very close of the object emitting the magnetic field.
As those responsible for the project carried out at Imperial College London have commented, although the technology works perfectly, its short scope prevents it from really having a practical application. Even so, they warn that the transmission of electricity without cables improves day by day, ensuring that we are only in a first step that open the doors to drone flight without the need for batteries.
