As we move towards a sci-fi-like future, we have seen companies come up with many innovative technologies to charge up our electronic devices. So now, scientists have found a way to perfectly beam energy across a room that can potentially charge up any electronic device without any cables or wires. And it is all possible, thanks to a new prototype device which they named “anti-laser”.
With this device, the scientists finally saw this whole thing coming to life. You see, this “anti-laser” device is capable of receiving scattered energy beamed around a space in a haphazard manner which makes it possible to receive 99.996% of the sent power.
In the past, such experiments had a time-reversal symmetry. For instance, in a video, if a person is making a pizza, you will see the person place the sausages on the pizza bread. However, if you play the same video backward you will see the person taking the sausages off the bread and placing them back.
