Drones have been tipped for the widespread use in smart cities and this is especially the case when you look at delivery services. They are also helpful when it comes to surveillance and even rescue operations. When you look at the unmanned aerial vehicles on the other hand, you will soon see that this is limited to very small battery packs. This ultimately means that their flight time is very limited, to 20 minutes or less. Those who work in engineering jobs will understand how frustrating this can be.

Researchers who work at the Queen's University in Belfast are working hard to try and develop technologies that will try and stop all of this from happening and the way that they are doing this is by using microwave beams that will be sent from the ground. This could mean that drones are able to fly continuously and without any delay. Existing systems really do require very close proximity and this includes charging pads for smartphones and even electric cars as well. These are all based on electromagnetic systems. The researchers are also going to work hard to try and develop new and powerful transmitters. They are going to try and send microwaves into the air in the same way that you would a laser beam. For this reason, it needs to be focused into a very fine beam and the current technology that is around doesn't do that too well at the moment. Experts are also working hard to try and make sure that the transmitter is in order as well, and it's safe to say that things are looking great so far. The hard work that they are putting in is really paying off and the results are speaking for themselves.
